+ fix a use-after-free in dlg_remove_callback().
+ improve handling of SIGWINCH for several widgets (Debian #865840).
+ menubox, the point of the Debian report was that it would be nice
to increase the window size if the terminal size increases. Did
that as a special case less problematic than decreasing the
terminal size. Added samples/menubox11 to demonstrate by
comparison with menubox10 a problem with debconf which puts extra
newlines in the caption that interfere with autowrap.

e.g., with "--trim" (report by Jarno Suni).
+ improve documentation of the various whitespace-filtering options,
to show which take precedence (Debian #867536, cf: Debian #102942).
+ modify msgbox.c, yesno.c to bind SCROLLKEY_BINDINGS before
TRAVERSE_BINDINGS so that up/down arrow will by default scroll the
message up/down rather than be aliases for tab-traversal (report by
Fredrik Kers).
+ modify dump_one_binding() to show when a binding is overridden.
+ improve format of trace-file, making comment-syntax consistent,
as well as showing argv-splitting as a series of comments.
+ modify dlg_string_to_argv() to change the quoting behavior to be
more consistent with shell behavior (patch by Denilson Sa Maia).
+ modify dlg_getc() to return ESC when a timeout expires, notifying
callers that a quit occurred rather than exiting the application
(suggested by Rodrigo Freitas).
+ modify handle_inputs() to ensure cursor-visibility is restored when
there is no input character available (report by Guillaume Vareille).
+ improve comment in manual page regarding which widgets can use the
"--help-button" (prompted by discussion with Csanyi Pal).
+ add a check for valid object pointer in tailbox's main loop since
the getc-callback may have been freed within ui_getc.c (report by
"David").

http://translationproject.org/latest/dialog/
+ update config.guess, config.sub

2017/01/31
+ use DLG_TRACE macro consistently to make "--disable-trace" configure
option work.
+ modify buildlist widget to support option "--reorder" for to allow
user to reorder the data based on the sequence of selections
(discussion with Paraic O'Ceallaigh).
+ fill background color on unused parts of buildlist.
+ fix a minor error in buildlist which let pageup switch columns.
+ change several calls to dlg_trace_msg to prefix with "#" to make
the trace logs more consistent for parsing.

+ further improve performance with very long command-lines by changes
to howmany_tags().
+ modify dlg_string_to_argv() to convert escaped double-quotes to
plain double-quotes when within a double-quoted string.
+ modify makefile to apply CFLAGS to linking
+ modify dlg_string_to_argv() to ignore escaped newlines except when
quoted, fixing a problem with samples/checklist9.
+ interpret $DIALOGOPTS before expanding "--file", etc., to allow
the environment variable to turn on tracing in that process.
+ improve performance when processing very long command lines, e.g.,
using "--file" by changing dialog_opts[] to an array of pointers to
the expanded argv[] (discussion with Lars Tauber).
+ modified autoconf macros
+ CF_CC_ENV_FLAGS amend the last change to move only the
preprocessor, optimization and warning flags to CPPFLAGS and
CFLAGS, leaving the residue in CC. That happens to work for gcc's
various "model" options, but may require tuning for other compilers
+ CF_LARGEFILE workaround for clang exit-code vs warnings
+ CF_MATH_LIB quiet strict gcc warning
+ CF_WITH_LIBTOOL fix a few places in configure/build scripts where
DESTDIR and rpath were combined
+ CF_XOPEN_SOURCE add "uclinux" to list of Linux's

2016/08/28
+ improve parsing and trace for "bindkey", to convert space to/from
"\s", as well as handle octal escapes for single byte characters.
+ change explicit checks for space character used for select or toggle
to make this rebindable to "TOGGLE" (prompted by discussion with
Paul van Tilburg).
+ add default bindings for cursor left/right to formbox. The cursor
left/right cases were replaced with rebindable symbols in 2005/12/07
without providing these keys as default values (report/patch by
Miroslav Lichvar).
+ modified autoconf macros
+ CF_PROG_LINT add cpplint to programs to use; drop ad hoc tdlint and
alint.
+ CF_CC_ENV_FLAGS don't limit the check to -I, -U and -D options,
since the added options can include various compiler options before
and after preprocessor options.
+ CF_GNU_SOURCE recent glibc (Debian 2.23-4 for example) has
misordered ifdef/checks for new symbol _DEFAULT_SOURCE, producing
warning messages when only _GNU_SOURCE is defined. Add a followup
check to define _DEFAULT_SOURCE.
+ CF_XOPEN_SOURCE use _GNU_SOURCE for cygwin headers, tested with
cygwin 2.3, 2.5 (patch by Corinna Vinschen).
+ mention --no-collapse option in manual page description of
--tab-correct option.
+ update config.guess, config.sub

2016/04/24
+ fix a special case in drawing shadow on a line-drawing cell where the
alternate-character set flag was lost (report by Martin Kravec).
+ fix a regression from 2015/05/13 changes for escaping; it is
necessary to retain backslashes within quotes to make "\Z" escapes
work (report by Marcin Krol).
+ fix test package for RPMs; changes in 2015 omitted symbolic links
for the library.
+ fix typo in help message for "--buildlist" (report by Rihards Olups).
+ modified autoconf macros
+ CF_PROG_AR, CF_AR_FLAGS added to improve check for archive tool.
+ CF_LD_RPATH_OPT, change FreeBSD to use -Wl,-rpath rather than
-rpath option. According to FreeBSD #178732, either works since
FreeBSD 4.x; however scons does not accept anything except the
-Wl,-rpath form.
+ CF_WITH_NCURSES_ETC, change from ncurses to check for pthreads
dependency.

2016/02/09
+ modify editbox widget to add a trailing newline if the text has none
to ensure the last line is not ignored (report by Florent Rougon).
+ change mouse initialization to look for button-presses rather than
button-clicks, for better response.
+ modify dump_curses_key() to show mouse-coding in readable form.
+ correct mapping of mouse-clicks on the day-grid in calendar widget
when "--week-start" is used to set the start of the week (report by
Stefan Vogtner).
> integrated changes from Stefan Vogtner:
+ use Gregorian algorithm for leap year
+ use mktime if available; calendar was written just as it became
standard.

2016/01/26 - release 1.3
+ correct --infobox documentation, which said it shows an OK button.
+ fix a couple of place in test-scripts which referred to $SIG_TRAP
rather than $SIG_QUIT
+ reorganize dialog.3, to use subsections for generating navigation
pane, using man2html
+ add "--week-start" option for calendar widget (prompted by discussion
with Stefan Vogtner).

the filled-in text area do not access past the end of the array
(report by Stefan Vogtner).
+ update configure macros from ncurses changes.
+ update config.guess, config.sub

2015/09/20
+ decrease table value for minimum number of arguments for the widgets
which use --no-items option (report by Raven Singularity).

+ use $SHELL consistently, deprecate non-POSIX shell
+ PKG_CONFIG may simply be unset - fix
+ add option to allow changing ABI version, from ncurses6.

2015/05/28
+ fixes for two autoconf macros, CF_ADD_INCDIR and CF_NCURSES_CONFIG
from work on ncurses.
+ build-fix for NetBSD curses (patch by Matthias Scheler).

2015/05/13
+ add configure option --with-install-prefix, like ncurses.
+ add --with-screen and related configure options from ncurses-examples
to allow building with ncurses6 test-packages.
+ update configure macros for improved coding style from lynx changes.
+ updated ro.po from
http://translationproject.org/latest/dialog/
+ update config.guess, config.sub
> patches by Florent Rougon:
+ fix two bugs in the "--file" option.
+ When the number of arguments read from the included file is 0, the
code used to just skip over '--file' and its argument instead of
removing them from the argument list, causing "Error: Unknown
option --file" later on.
+ In the alternative case (at least one argument read from the file),
the previous code used to do '--j;' in order to "force rescan" of
the inserted arguments. However, control then flowed to outer
blocks where a '++j;' counteracted this measure, causing "Error:
Unknown option --msgbox" (for instance) later on.
+ modify escaping in argv.c to be more uniform, whether or not the
backslash is found within a parameter.

2015/02/25
+ modify gauge widget to keep from erasing a second gauge widget, e.g.,
via the "--and-widget" option. This is a cosmetic change to match
behavior of dialog 1.0 (report by Jason Orendorf).
+ add configure option "--with-man2html"
+ add configure options for versioned symbols, from ongoing work on
ncurses.
+ update configure macros, e.g., for shared libraries

2015/01/25
+ suppress highlighting of character which denotes an abbreviation or
shortcut for the OK/Cancel and other buttons for these widgets, which
use abbreviations for the list shown on the screen: buildlist,
checklist/radiobox, menubox, treeview (Debian #775295).
+ add grid up/left and down/right bindings in editbox.c as synonyms for
field prev and next, respectively when handling the OK/Cancel buttons
(Debian #775294).

2014/09/11
+ correct malloc-size for change to prgbox.

2014/09/10
+ fixes to make "-c" option work when passing command to shell for the
prgbox widget, for example in samples/prgbox2 (report by Korantin
Auguste).

2014/09/08
+ fix an out-of-bounds array index in buildlist widget (report by

2013/09/02
+ modify makefile rule to make the ".png" filenames created by groff
predictable.
+ add option --help-tags to allow scripts to get the item's tag field
consistently from help- and help-item button results rather than
getting the item's text for the latter (discussion with Florent
Rougon).
+ correct manpage discussion of DIALOG_ITEM_HELP versus --item-help,
as well as --help-button return status (report by Florent Rougon).
+ correct limit used for --hline option (report by Devin Teske,
cf: 2011/06/30).
+ do not print empty "[]" if a --hline option was given with an empty
value (report by Devin Teske).
+ miscellaneous configure script fixes/updates. In particular, add
option --with-shared which builds shared libraries without a libtool
dependency.
+ add FreeBSD port-files for test-builds.
+ update lt.po, add fa.po from
http://translationproject.org/latest/dialog/
+ update config.guess, config.sub

2013/05/23
+ modify ifdef in arrows.c to work around packages which use the
wide-character ncursesw headers with the ncurses library (report
by Aleksey Cheusov).
+ correct workaround for xterm alternate-screen to work with/without
the fix made in ncurses that makes putp() always write to the
standard output (Debian #708829).

2013/03/15
+ update zh_TW.po, add an.po from
http://translationproject.org/latest/dialog/

2012/12/30 - release 1.2

+ add buildlist, rangebox and treeview dialogs, like Xdialog.
+ remove obsolete workaround for ncurses 4.2 scrolling in checklist
and menubox.
+ improve dialog_helpfile() by preventing it from showing extra buttons
(suggested by xDog Walker).
+ correct logic in formbox's scroll_next() function (report by xDog
Walker).
+ fix a case with inputbox widget where preset input text is not shown
until moving the cursor within the text (report by xDog Walker).
+ handle SIGCHLD in dialog_prgbox() to eliminate defunct processes
(report by xDog Walker).
+ improve the way "hotkeys" are assigned to widget buttons by checking
if a given key has already been used in the row of buttons (Debian
#684933).
+ amend fix for --trace parsing from 2012/07/03, which sometimes
skipped a parameter (report by xDog Walker).

+ use "id" rather than "$GROUPS", use sed to work with Solaris.
+ use sed to split-up the rename results to work with HPUX.
+ fix regression in msgbox (ArchLinux #30574)

2012/07/03
+ modify prgbox widget to work with --extra-button, etc.
+ add case values to several widgets to allow for mouse-clicks with
"--extra-button" and "--help-button" additions.
+ correct timebox widget's exit code for "--extra-button" when handing
the "enter" key.
+ modify msgbox widget to honor "--extra-button".
+ corrected processing of "--trace" option, which did not update the
index into command-line to point past its value.
+ add a check in dialog program for valid characters used in option,
e.g., to generate an error if a script attempts to add option value
using "=" rather than with whitespace.
+ add new command-line option --default-button and library function
dlg_default_button() to retrieve the value set by the option
to provide a way to set the default button directly rather than
by combining --nook, etc. (patch by Zoltan Kelemen).
+ amend include of unctrl.h to apply only to the case where curses.h
is included, to avoid conflict of ncurses' unctrl.h with a system
implementation (report by Martin Roedlach)
+ add limit-check to dlg_toupper() in non-wide curses mode to work
when non-character values such as arrow-key codes are passed to
it (patch by Zoltan Kelemen).
+ override timeout value, e.g., as set via --timeout command-line
option in pause widget because that interferes with pause's behavior
(report by Jan Spitalnik).
+ modify samples/inputmenu* to allow ":" in renamed text (report by
Andreas Stoewing).
+ modify double-quoting to make it more consistent, i.e., checklist
output is quoted only when needed. This fixes the case where
single-quotes were used whether or not needed, but also modifies
older checklist behavior for double-quoting which always added those
(Debian #663664).
+ correct exit-code used in inputmenu for "rename" button (Debian
#673041, forwarded from Ubuntu #333909, patch by Lebedev Vadim).
+ update el.po and hr.po from
http://translationproject.org/latest/dialog/
+ use checkbashisms to clean up sample scripts.

2012/02/15
+ modify menubox.c to use the same improvement as in checklist.c
+ improve auto width computation for checklist widget by using
dlg_calc_list_width as in the non-auto case (Edho Arief).
+ eliminate some bashisms in the sample scripts (Pedro Giffuni).
+ makefile fixes from FreeBSD ports (Li-Wen Hsu):
+ make --with-package option of configure script work.
+ get LIBTOOL_VERSION from configure script, needed by
${LIBTOOL_VERSION} in LIBTOOL_CREATE (LIB_CREATE in configure and
aclocal.m4)
+ update cs.po and sr.po from
http://translationproject.org/latest/dialog/
+ updated configure script macros, improving CF_XOPEN_SOURCE among
other fixes.

2011/10/20
+ fix --analyze warnings for clang versions 2.8, 2.9.
+ add configure check for lint program.
+ add check in dlg_getc() in case its window is freed as a side effect
of removing callbacks.
+ fix logic in freeing subwindows (report by xDog Walker).
+ fix a regression in logic distinguishing between inputmenu and menu
widgets (report by xDog Walker).
+ minor fixes to library manpage.

2011/10/18
+ modify header-sh.in to work around limit on sed script length on
HPUX.
+ add a special case of parameter parsing for "--trace" to the
initialization done before calling init_dialog(), to allow users to
capture the initial state of the parameter list before any options
are processed and removed. This is only done if "--trace" is the
first option, otherwise it is handled in the common options as before
(report by xDog Walker).
+ modify samples/testdata-8bit, discarding $1 from the parameter list
if it was used, so that the source'ing scripts can consistently use
"$@" to insert parameters before the widget, e.g., as an alternative
to using $DIALOGOPTS (report by xDog Walker).
+ modify treatment of function pointers in menubox.c, make
dlg_renamed_menutext() and dlg_dummy_menutext() visible to library
users (request by xDog Walker).
+ add dlg_count_real_columns(), use to modify centering for "--hline"
text to account for "\Z"s (report by xDog Walker).
+ improve check in dlg_draw_arrows2() for conflict between the window
title and up-arrow marker to take into account that the given window
may not be the top-level window of the widget.
+ change width of page up/down mouse areas in fselect panes to use the
full width of the panes rather than only the portion from the left
margin to the up/down arrow.
+ add/use dlg_draw_box2() and dlg_draw_bottom_box2() to use the
secondary borders.
+ modify rc-file read/write to accept/generate color values that refer
to previously-processed items in the color table. This reduces the
number of distinct colors that must be specified to set up a color
scheme.
+ add color table entries for secondary borders, i.e., the ones that
are normally drawn with the dialog's text-colors (Debian #641168).
+ modify fselect.c to scan the current directory if the input field
happens to be empty (Debian #640905).
+ repeated the discussion of environment variables that can override
the exit-status values in the manpage's return-codes section
(Debian #642105).
+ add an example to the manpage showing how to override the form
widget's keys used for field/button traversal (Debian #642108).
+ modify call to dlg_register_window() in formbox.c so that the editing
bindings are attached to the form sub-window rather than the
top-level dialog window. Also change the name by which the editing
bindings are bound for editbox.c, fselect.c and inputbox.c, so that
the editing and navigation bindings can be different.
+ correct logic in dlg_lookup_key() so that it matches the widget name
before using a binding from .dialogrc, allowing the inner/outer
windows of form and other editing widgets to have different bindings.
+ modify dlg_register_window() to call dlg_dump_window_keys() after
its updates, via the --trace output, to supplement the manpage
description of key bindings (Debian #642108).
+ add DLGK_FORM_PREV and DLGK_FORM_NEXT key-bindings to form.c, to
allow binding a single key to traverse both form-fields and buttons
(Debian #642108).
+ modify dlg_parse_rc() to check for error return from
dlg_parse_bindkey().
+ add function dlg_dump_window_keys(), to help with debugging widgets.
+ add CR, LF, TAB, FF and ESC to table of curses names to help make
key bindings more readable.
+ update table of dialog key-names so that helpfile and trace are
dumped properly.
+ correct dlg_dump_keys(), which was showing only the first item in
the matched binding table.
+ save/restore window current position in dlg_update_mixedgauge().
+ pass return-code from pause_for_ok() from dlg_progressbox() when
pauseopt is set, rather than only DLG_OK.
+ call setlocale() in init_dialog() rather than relying on on-demand
use within inputstr.c, since there are paths in textbox widget which
do not exercise the latter (report by xDog Walker).
+ fix some places where checks for "\Z" were done without also checking
dialog_vars.colors (report by Moray Henderson).
+ correct logic for DIALOGOPTS parsing so that the parse happens only
once unless memory leak checking is enabled (report by xDog Walker).
+ remove an incorrect free() call in dlg_free_gauge() (report by xDog
Walker).
+ modify dlg_trace_win() to log wide-characters (report by xDog Walker).
+ make traces shorter by skipping repeated ERR's, but showing the
number skipped (report by xDog Walker).
+ improve description in manpage to distinguish program box and
progress box from tailboxes (adapted from email by xDog Walker).
+ modify dlg_trace_win() so that it looks for the topmost window in a
dialog. Because subwindows share space with the top window, tracing
the latter shows the whole widget (report by xDog Walker).
+ expand tracing so that each window is traced before soliciting input,
making the ^T feature to print a window on demand partly redundant
(suggested by xDog Walker).
+ cosmetic change in dialog.h to avoid "*/*" strings from comments next
to "*" (report by xDog Walker).
+ ensure result from dlg_align_columns() has trailing null on each
string. Analysis was hindered by libc6's continuance of libc5's
early-1990s misfeature of clearing the result from malloc, noting
that libc6's documentation incorrectly claims that it does not do
this (report by xDog Walker).

2011/07/07
+ modify util.c to work better with old versions of ncurses:
+ suppress use of wchgat() before fix in 20060715 which is needed
for simple shadow manipulation used here in 2011/06/30 (report
by xDog Walker).
+ add a null-pointer check in dlg_print_scrolled()
+ fix a regression in dlg_getc() introduced by changes to intercept
F1 for help-popup (report by xDog Walker).

2011/06/30
+ correct license statement for prgbox.c (Debian #632198).
+ correct layout when "--colors" is used, by discounting characters in
the escape sequences from the column counts (report by xDog Walker).
+ modify dlg_checklist() so that only one item in the list can
initially be selected (report by xDog Walker).
+ add/use macro dlg_enter_buttoncode() to improve implementation of
"--nook" option (report by xDog Walker).
+ add option "--no-nl-expand" to suppress the conversion of "\n"
strings into newlines (request by xDog Walker).
+ modify LIB_CREATE symbol in makefile.in to include the library
dependencies such as ncurses. This is needed when dynamically
loading the library (report/analysis by xDog Walker).
+ modify dlg_exit_label() to suppress the Cancel button, for
consistency.
+ modify dlg_exit_label() to honor the --nook option, except when there
is no other button, e.g., the help-button.
+ modify dlg_exit_buttoncode() so that it returns the proper code for
help-button (report by xDog Walker).
+ correct loop limit when processing "--column-separator" (report by
xDog Walker).
+ modify handling of "--version" and "--help" to ensure that they are
processed, and exit before widgets. Separate "--print-version"
from "--version", allowing its output to be interspersed with
widget output (report by xDog Walker).
+ correct a few places where "--version" or "--help" options went
always to stdout rather than allowing redirection with the "--stderr"
option (report by xDog Walker).
+ improve repainting after erasing a widget and its shadow.
+ add "--hline" and "--hfile" options for compatibility with FreeBSD
dialog (request by Devin Teske).
+ add dialog version message when opening a trace file (request by
xDog Walker).
+ show filename of rc-file in traces.
+ add piped-in data for gauge widget to traces.
+ add entrypoints to gauge widget, for allocating, updating and freeing
the widget (adapted from patch by Stephen Hurd).
+ fix a reference to freed memory in the gauge widget.
+ fix --no-mouse option by actually closing the mouse (report by
xDog Walker).
+ add sk.po from
http://translationproject.org/latest/dialog/
+ limit Solaris xpg4 portability fix for redefinition of ERR to cover
the specific value found in <sys/regset.h>, in case an application
includes dialog.h after curses.h (FreeBSD #156601, report by Jaakko
Heinonen, Stephen Hurd).
+ updated configure macros:
+ CF_CURSES_CPPFLAGS,
+ CF_CURSES_LIBS, make checks for special libraries on hpux10 and
sunos4 optional
+ CF_CURSES_FUNCS, workaround for bug in gcc 4.2.1 (FreeBSD 8.1)
which caused part of test program to be omitted, i.e., when it saw
two return-statements in a row it omitted the _first_ one. Also
add expression to pointer check to help FreeBSD's linker decide it
should be validated. Just an assignment was not enough. Also, add
check for unctrl.h
+ CF_CURSES_HEADER, change order for curses.h / ncurses.h pairs to
put ncurses.h first, which will tend to provide the same #define's
as in CF_NCURSES_HEADER (report by Dennis Preiser).
+ CF_CURSES_TERM_H, modify to avoid spurious check for
<curses.hterm.h> if there is no ncurses version. Look for
ncurses's term.h anyway, to work around breakage by packagers who
separate ncurses' header files.
+ CF_DISABLE_RPATH_HACK, fix garbled message
+ CF_LD_RPATH_OPT, add mirbsd
+ CF_MAKEFLAGS, filter out GNU make's entering/leaving messages.
This only appeared when using the macro in a dpkg script, though it
should have in other cases.
+ CF_RPATH_HACK, add a check for libraries not found, e.g., from
suppressed functionality of gcc in linking from /usr/local/lib, and
add a -L option to help work around this.
+ CF_XOPEN_SOURCE, workaround for cygwin to get ncurses' configure
script to define _XOPEN_SOURCE_EXTENDED (cygwin's features.h
doesn't do anything, so it needs a crutch).
+ update config.guess, config.sub

2011/03/02
+ add --prgbox and --programbox (adapted from patch by David Boyd).
+ add sl.po from
http://translationproject.org/latest/dialog/
+ fix timeouts from 2011/01/18, which were being interpreted as
milliseconds rather than seconds (report by Luis Moreira).

2011/01/18
+ fix inconsistency in return-codes for textbox when help-button is
used by making dlg_exit_buttoncode() a wrapper for
dlg_ok_buttoncode().
+ modify pause widget to use dlg_ok_buttoncode(), so help-button works.
+ correct two infobox sample scripts, which did not pass extra
command-line parameters due to quoting problems.
+ add a limit-check to the timebox widget (patch by Garrett Cooper).
+ modify --trace option to also trace the command-line parameters.
+ account for combining characters when wrapping text (Debian #570634).
+ correct handling of SIGWINCH in gauge widget (Debian #305705).
+ add gauge_color, to make guage's progress-bar distinct from
title_color (request by Dominic Derdau).
+ update fi.po from
http://translationproject.org/latest/dialog/
as well as resync line-numbers in the other po-files.
+ modify configure script and dialog program to build with NetBSD's
wide-character curses functions, including workarounds for its
incorrect WACS_xxx definitions. Some of the UTF-8 examples work.
+ add back-tab for traversal of tailboxbg widgets, for symmetry with
tab-traversal.
+ reduce flicker in tailboxbg by checking if the input file size has
changed.
+ modify internals of callbacks to avoid blocking reads of their
associated files by keyboard input.
+ add command-line option --no-mouse, to suppress use of mouse.
+ add configure option --enable-header-subdir to allow the header files
to be installed into a subdirectory named for the package.
+ modify dlg_restore_vars() to retain the updated values of
input_result and input_length, eliminating the need for a caller to
provide their own user buffer (prompted by report by Thiago Bimbatti
Felicio).
+ add a null-pointer check in show_result() for
dialog_vars.input_result, and ensure it is set to null after freeing
(prompted by report by Thiago Bimbatti Felicio).
+ change order of -I options in CPPFLAGS (report by Michel Feldheim)
+ modify pause-widget so that it no longer exits when an unrecognized
key is pressed (patch by Creidieki M Crouch).
+ add --with-package option to configure script to allow renaming
of the dialog program and library, to support the package scripts.
+ add Debian and RPM package scripts for test-builds.
+ several improvements to configure script:
+ quote params of ifelse()
+ change obsolete ${name-value} to standard ${name:-value}
+ use new macros CF_ADD_LIB/CF_ADD_LIBS to enforce consistency.
+ AM_GNU_GETTEXT, drop $MKINSTALLDIRS, use "mkdir -p" consistently.
+ CF_ADD_SUBDIR_PATH, workaround - if $prefix was not mkdir'd yet, no
directories were added.
+ CF_BUNDLED_INTL, add --with-textdomain option, to use with lynx-dev
package
+ CF_FIND_LINKAGE, simplify save/restore of $LIBS
+ CF_GCC_WARNINGS, fix for Mac OS X (compiler makes conftest.dSYM
directory)
+ CF_HEADER_PATH, don't search for variations of everything in the
current include-path
+ CF_WITH_CURSES_DIR, move the calls to CF_ADD_INCDIR and
CF_ADD_LIBDIR for the curses-directory here, from
CF_NCURSES_CPPFLAGS and CF_NCURSES_LDFLAGS, so it will work even
with the default checking, e.g., no --with-ncurses, etc.
+ update config.guess, config.sub

2010/04/28
+ several improvements to configure script:
+ modify CF_CURSES_TERM_H to handle cases such as cygwin where
packager has installed curses.h and term.h in different
directories, e.g., to wedge in a termcap library.
+ modify CF_XOPEN_SOURCE, adding special case for OpenSolaris
+ modify CF_MAKE_TAGS to add check for exctags and exetags, prefer to
ctags and etags to work around pkgsrc (NetBSD) renaming.
+ correct CF_FIND_LINKAGE, setting cache variable for library_file in
the special case where no directory search is made.
+ improve CF_GCC_VERSION, suppress stderr for c89 alias of gcc.
+ improve CF_GCC_WARNINGS, moving -W and -Wall into the list to
check, since c89 alias for gcc complains about these options.
+ modify CF_HEADER_PATH, to not search for variations of everything
in the current include-path
+ use "mkdir -p", remove mkdirs.sh
+ use CF_CURSES_HEADER to fill in possible subdirectory used for
ncurses header filename.
+ modify CF_XOPEN_CURSES to work around current ncurse header loss of
predefinition of _XOPEN_SOURCE_EXTENDED
+ add "--disable-rpath-hack" option, along with scripting to add
rpath option to libraries found in unusual places.
+ modify pause widget to autosize like gauge, and to omit the area for
buttons when none are displayed.
+ fix an infinite loop in dlg_button_layout() if there are no buttons
to display (Debian #579390).
+ add makefile rules for generating html, etc., documentation from
nroff.
> patches by Samuel Martín Moro
+ reset errors in tailbox before reading new character.
+ modify dlg_draw_scrollbar(), omitting hiding percentages in boxes
when no arrows or scrollbar are needed.
+ correct value of row for scrollbars in formbox.
+ update es.po from
http://translationproject.org/latest/dialog/

2010/01/19
+ split up binding tables in inputbox and similar widgets to avoid
conflict between cursor-key use for input-string versus navigation
(report by slakmagik).
+ if strftime() is available, support --time-format option for timebox
widget.
+ if strftime() is available, support --date-format option for calendar
widget (request by Walter Harms).
+ build-fixes for linking to intl library in /usr/local
+ add --scrollbar option, use in most widgets to show a scrollbar on
the right margin of the data. That is cosmetic, does not respond to
the mouse.
+ reuse functions from msgbox to allow prompt for yesno box to be
scrolled in a too-small window.
+ correct mapping of button-codes with --nook option (report by Lebedev
Vadim).
+ cleanup sample scripts using new utility scripts setup-* and report-*,
and allow command-line parameters to be added, for ad hoc testing.
+ correct change to tailbox widget from 2009/02/22 using
dlg_button_layout(), which broke that widget.
+ document some of the portability caveats.
+ modify gauge widget to service callbacks (prompted by patch and
comments by Frank Sorenson).
+ modify editbox to allow its input buffer to be larger than MAX_LEN
unless bounded by the --max-input option, and add limit-checks for
the buffer (report by slakmagik).
+ improve manpage description of --checklist (report by Isaac Good).
+ several improvements to configure script macros: CF_ADD_CFLAGS
CF_CURSES_FUNCS CF_DISABLE_ECHO CF_GCC_ATTRIBUTES CF_MATH_LIB
CF_POSIX_C_SOURCE CF_REMOVE_DEFINE CF_WITH_LIBTOOL CF_XOPEN_SOURCE
+ add is.po, lv.po, sw.po from
http://translationproject.org/latest/dialog/
+ update de.po, id.po, pl.po, pt_BR.po, vi.po from
http://translationproject.org/latest/dialog/

2009/02/22
+ do not display top-arrows for scrolling if they would overwrite the
title (report by slakmagik)
+ consistently use dlg_button_layout() when autosizing widgets (report
by slakmagik).
+ add "-" and "+" bindings to timebox widget.
+ add "-" and "+" bindings to calendar widget (OpenSolaris #6739031).
+ review/fix other widgets to ensure that they exit on error, e.g.,
editbox.c
+ modify check in dlg_getc() to treat closure of either stdin or stdout
as an error, rather than both. This is more stringent than the check
added in 2007/07/04.
+ modify dlg_result_key() to map curses ERR to dialog's error exit
(adapted from patch by Domagoj Pensa).
+ updated several configure script macros:
+ consistently append, rather then prepend, to $CFLAGS
+ add cases for AIX 6, mint, and dragonfly to CF_XOPEN_SOURCE
+ use $PATH_SEPARATOR rather than $PATHSEP
+ improve CF_FIND_LINKAGE, use in checks for more libraries, e.g.,
libutf8 and libiconv.
+ update da.po, ru.po from
http://translationproject.org/latest/dialog/
+ update config.guess, config.sub

2008/08/19
+ amend changes to quoting; by default, the checklist widget quotes its
output except when --separate-output is used (Debian #495600).
+ add eo.po from
http://translationproject.org/latest/dialog/

2008/07/27
+ add pointer-check when closing piped input (cf: 2007/03/25)
+ use here-documents rather than echo, when passing backslashes in
strings, to accommodate the Debian shell "dash" (Debian #489563).
+ recode several ".po" files to UTF-8 for consistency.
+ change --separator to be an alias for --output-separator, for
compatibility with Xdialog.
+ add --output-separator option to allow scripts to change the output
separator from a newline (for --separate-output) or a space. This
applies to other widgets such as forms and editboxes which normally
use a newline.
+ add --column-separator option, to tell where column-aligned data for
radio/checkboxes or menus should be split into columns (request by
Ben Dibbens).
+ add id.po, ku.po, lt.po, nb.po and update ca.po, fr.po, gl.po, ja.po,
th.po from
http://translationproject.org/latest/dialog/
+ add "--quoted" option, to quote values returned by formbox, etc.
+ change names of EX/ES macros in dialog.1 to work around name-
pollution caused by changes in Debian #470729.

2008/03/16
+ modify dlg_mouse_wgetch() to loop only on errors that it detects,
rather than on errors forwarded from dlg_getc(), in case those are
due to a disconnected terminal (report by Anatoli Sakhnik).
+ allow "default" color in dialogrc file (request by Dashing).
+ fix an indexing error in formbox (Debian #469190, report by Dmitry
Gomerman, patch by Vladimir Mezentsev).
+ add bindings for CTL/N, CTL/P to checklist, fselect and menubox
widgets (prompted by discussion with John Gatewood Ham).
+ add be@latin.po, th.po and update zh_TW.po from
http://translationproject.org/latest/dialog/
> patches by Peter Åstrand:
+ modify dlg_auto_sizefile() to ensure the computed height and width
do not extend beyond the screen size.
+ use unctrl() to make inputstr.c work with Solaris curses.
> patches by Yura Kalinichenko:
+ extend pause widget to use ok/cancel buttons (the former giving the
same result as a timeout), rather than an exit-button.
+ fix initialization parameter of inputbox for multibyte characters.

2007/10/28
+ improve layout of checklist.c, menubox.c, ensuring that the list fits
within the available space (report by Gordon Schumacher).
+ undo removal of redundant chunk from checklist.c in 2007/02/27,
since some scripts depend on this (Debian #443077).
+ update nl.po from
http://translationproject.org/latest/dialog/

2007/09/30
+ correct cursor position in editbox after deleting past left margin
(report by Joe McDonagh).
+ add "--no-ok" option (patch by Klaus Knopper).
+ modify "--file" option to allow it to read from sources other than
a regular file (patch by Pieter van Beek).
+ improved hi.po (Hindi) (from Klaus Knopper).
+ fix masking of attributes in dlg_draw_shadow() which lost
line-drawing bit (report by David Everly).
+ fix editbox widget to handle zero-length files (report by Joe
McDonagh).
+ update "po" files eu.po ga.po it.po ms.po sv.po vi.po wa.po zh_CN.po
from
http://translationproject.org/latest/dialog/

2007/07/04
+ revise the resizable shadows so textbox's search dialog has text
visible in the shadow again.
+ improve the prefixing of autoconf-related symbols in the installed
header files, taking into account symbols which are not mentioned in
dlg_config.h
+ add a check when ERR returned from wgetch() to ensure that the
input/output streams are still valid. If that happens, force
ESC to be returned, quitting dialog (report by Reiner Huober).
+ add extern "C" declarations to dlg_keys.h so the corresponding
function declarations are exported to C++ as C symbols.
+ update config.guess, config.sub

2007/06/04
+ fix a memory leak in editbox.c
+ revise change from 2007/02/27 which moved the logic for trimming
option text out of the loop because that moved it before
initialization of the "--trim" option. Put it back in the loop, but
limit the tokens which are trimmed to cover only those for the
current widget. Also ensure that all tokens for a widget are
trimmed, rather than only the first, which is usually text (report by
Lai Zit Seng).
+ add _FILE_OFFSET_BITS definition in CF_LARGEFILE configure macro.

2007/05/28
+ revise changes needed to make textbox's searchbox handle ncurses
resizing events, e.g., by handling the ERR in that code rather than
in dlg_getc() (Debian #423732).

2007/05/14
+ supply a repaint_text() call in tailbox.c which was bypassed because
dlg_getc() now retries on ERR (Debian #423732, cf: 2007/02/27).
+ modify dlg_getc() to fix regression in 2007/02/27 for use of
timeouts, broken by fixes to allow resizing of textbox (patch by
Arnaud Fontaine, Debian #418905).
+ modify dlg_getc() to fix regression in use of TAB for traversal of
tailboxbg widgets due to changes for user-definable key bindings
(Debian #418917, cf: 2005/12/07).

2007/04/09
+ add case in dlg_getc() to handle tab for traversing between widgets
as in the samples/tailboxbg1 script. Normally the key binding
overrides, except for the special case where multiple widgets are
available.
+ add configure --with-libtool-opts, which passes its value to the
library creation and linkage passes, e.g.,
--with-libtool-opts=-static
to force the result to be static libraries (prompted by a related
request by Santiago Vila).
> several fixes based on Coverity scan:
+ fix memory leak in timebox, calendar widgets if the widget cannot
be created.
+ fix memory leak in dlg_key.c if a user binding's storage cannot
be allocated.
+ fix improperly delinked entry in dlg_del_window().

2007/03/25
+ improve mkdirs.sh to ignore error from mkdir if the target directory
happens to already exist (suggested by Harald van Dijk).
+ amend documentation for --gauge to reflect longstanding quirk which
allows it to read percentage from the first line after an "XXX"
(Debian #415596).
+ fix makefile dependency so "configure && make install-lib" works.
+ fix resizing of msgbox; the message was not repainted (Debian
#415022, patch by Brian Rolfe).
+ fix typo in makefile LIB_OBJECT symbol from 2007/02/27 changes.
+ improve CF_MBSTATE_T by including stdio.h, needed on Tru64 to make
the test-compile work.
+ change makefile to install dialog.3 as part of install-lib rather
than install-man (report by Thomas Klausner).
+ use $(INSTALL_SCRIPT) for installing dialog-config (report by
Santiago Vila).

2007/02/27 - release 1.1
+ mark as "dialog 1.1"
+ add dialog-config script, which provides applications with compile-
and link-information for using the dialog library.
+ move calls to dlg_trim_string() out of loop in dialog.c, so each
string is trimmed once (report by Ivanov Makcim).
+ modify textbox.c to allow resizing while the search box is presented.
This relies on bug-fix in ncurses 5.6 20070224.
+ use dgettext() rather than gettext() to allow libdialog to use the
messages installed for dialog (patch by Vajna Miklos).
+ modify inputbox to position the cursor initially at the end of any
initial-text (request by Klaus Knopper).
+ add configure --with-valgrind for testing.
+ add --trace option, for debugging.
+ add --ascii-lines and --no-lines options to control the way the
line-drawing characters are rendered (request by Klaus Knopper).
+ add --keep-tite option, to override suppression of smcup/rmcup
(termcap ti/te) strings which would switch to xterm's alternate
screen (Debian #380665).
+ modify fselect/dselect to use space-character as a completion
operator like tab in shells (patch by Yoram Bar Haim).
+ remove a redundant chunk from checklist.c which reported status a
second time if the help-button was pressed but no item-help option
was in effect (Andre C Barros).
+ fix return-status from "dialog --pause" (Debian #409254).
+ add --mixedform and --mixedgauge dialogs based on patch from
Kiran Cherupally.
+ add some notes on compatibility to the manpage.
+ add editbox dialog (compatible with Xdialog, Debian #368478).
+ add dselect dialog (compatible with Xdialog).
+ remove an incorrect initialization of .text_flen from 2005/12/07
changes, which made all fields in a form editable (Debian #404045).
+ report error and exit if a filename given for the --file option
cannot be opened (report by "Dog Walker").
+ make --program-prefix, etc., work in configure script, e.g., to make
program install as "cdialog". This does not alter the library name.
+ add install-bin, install-man (and uninstall) rules to makefile.
+ updates for configure script macros (originally vile, lynx, xterm):
AM_PATH_PROG_WITH_TEST, AM_WITH_NLS, CF_CURSES_CPPFLAGS,
CF_CURSES_LIBS, CF_INCLUDE_DIRS, CF_LARGEFILE, CF_MAKEFLAGS,
CF_PATH_SYNTAX, CF_SUBDIR_PATH, CF_SUBST, CF_WITH_DBMALLOC,
CF_WITH_DMALLOC, CF_WITH_LIBTOOL and CF_XOPEN_SOURCE.
+ update config.guess, config.sub
> adapted fixes from SuSE package (Werner Fink):
+ add some limit-checks in dlg_draw_shadow().
+ make shadows resizable, using new dlg_move_window() in msgbox.c
and yesno.c
+ add dialog_state.input, use this in end_dialog() to decide whether
to close pipe inputs and call _exit(), or simply call exit().
+ modify dlg_ctl_size() to check if the reason for failure is because
shadows were used; retry in that case without shadows.
+ add signal catcher for SIGSEGV.

2006/02/21
+ fix logic in split-out dlg_menu() to separate inputmenu and menu
handling (report by Auke Kok).

2006/01/26
+ fix fselect.c to compile properly with Intel compiler and largefile
option.
+ improve configure script checks for curses headers to work around
breakage in some packages, e.g., cygwin.
+ amend correction to menubox, fixes normal menus (Debian #349969).

2006/01/19
+ completed dialog.3 manpage
+ modify configure script option --with-gauge to cover all flavors of
the gauge (gauge, pause, progressbox).
+ add progressbox widget, a hybrid of gauge and tailbox (Reznic Valery).
+ fix a comparison in checklist.c to avoid unneeded arrows when the
list happens to fit in the window (patch by Peter Postma).
+ correct wrapping computation in print_line() from 2005/11/07 changes
(report by Barry Kauler).
+ update sv.po (comments only).
http://www.iro.umontreal.ca/translation/maint/dialog/
+ correct logic that passes the callback for menubox to do inputmenu
operations from 2005/12/7 changes (report by Reznic Valery).

2006/01/01
+ add a null-pointer check in dlg_register_buttons(), needed for the
tailboxbg (Debian #345524).
+ fix a few memory leaks reported by valgrind.

2005/12/19
+ correct return-values of new functions dlg_default_listitem() and
dlg_default_formitem() (Debian #344002).
+ add Swedish translation (Debian #343303, by Daniel Nylander)
+ begin function-summaries in dialog.3
+ update config.guess, config.sub

2005/12/07
+ change license to LGPL.
+ change naming convention in dlg_colors.h to make it easier to read,
and incidentally remove the last chunk of code preventing relicense.
+ add --passwordform (request by Reznic Valery).
+ modify pause.c, msgbox.c to work with --help-button.
+ modify formbox.c, inputbox.c, textbox.c, yesno.c to work with extra
button (adapted from Reznic Valery patch).
+ modify dlg_exit_label(), dlg_yes_labels() and dlg_ok_label() to allow
help-button (prompted by Reznic Valery patch).
+ add zh_CN.po file from
http://www.iro.umontreal.ca/translation/maint/dialog/
+ provide alternate interfaces for dialog_checklist(), dialog_menu()
and dialog_form(): dlg_checklist(), dlg_menu() and dlg_form()
(discussion with Michael Gebetsroither).
+ add/use dlg_result_key() to allow binding function keys to the
buttons.
+ implement user-definable key bindings in the rc-file.
+ modify inline cases for KEY_xxx values to use binding tables in new
module dlg_keys.c
+ add several DIALOG_STATE items to the rc file: aspect,
separate_widget, tab_len and visit_links
+ add a tab-adjustment to dlg_print_text() to improve solution from
2005/10/30, e.g., in the samples/form* scripts.
+ fix an off-by-one which made mouse-selection not work for menu items
past the first page (GenToo #112024, patch by Harald van Dijk).

2005/11/07
+ extend dlg_add_result() to allow caller to pass a null pointer
for dialog_vars.input_result (Debian #336986).
+ correct length used for text portion of radio/checkboxes (report by
Valentin Stoykov).
+ modify msgbox, textbox and center_label() to work properly for
LANG=bg_BG.utf8 examples by Valentin Stoykov.
+ modify use of freopen() to work with opaque FILE type on DragonFly
(report by Jeremy C Reed).
+ modify print_line() to compute columns, use that for the call to
dlg_print_line(). Fix a few places where strlen() was used instead
of dlg_count_columns() (reports by Valentin Stoykov).

2005/10/30
+ reviewed changes since beginning development in 1999, decided that
there are no appreciable portions of original code remaining.
Marked sources to correspond.
+ improve cache performance for inputstr.c using tsearch() rather than
a linked-list search (Debian #294853).
+ remove a special case for darwin in CF_XOPEN_SOURCE configure macro.
+ add ms.po file from
http://www.iro.umontreal.ca/translation/maint/dialog/
+ remove an assignment that caused the cursor to appear initially on a
form field rather than button (Debian #333506).
+ modify buttons.c to count columns rather than bytes, fixing case
where buttons were laid out incorrectly (report by Valentin Stoykov).
+ change dlg_print_text() to count columns rather than bytes, fixing
case where fewer columns were displayed in menu than expected
(report by Valentin Stoykov).

2005/10/05
+ improve fix for dlg_does_output(), eliminating redundant leading
separator.
+ fill background color for item-help text (report by Peter Postma).
+ correct interaction between --separate-output and --output-separator
broken in 2005/09/11 fix for Debian #326918 (Debian #331440).
+ update config.guess, config.sub

2005/09/11
+ undo doubled adjustment for left/right margins when wrapping text
for msgbox, gauge and pause (report by Xyba).
+ correct position of scrolled text in formbox broken by 2004/12/19
changes (report by Konrad Jelen).
+ call dlg_does_output() from dlg_add_result(), ensuring that
separators are used when combining widgets such as formbox (report by
John Suykerbuyk).
+ fix marker in textbox.c to make it disappear at the top of the file
(report by Patrick J. Volkerding).
+ fix marker shown in arrows.c for checklists, etc., which was "(+)"
where it should have been "(-)" (report/patch by Patrick J.
Volkerding).
+ fix --input-fd (changes in glibc since 2003 made dialog hang on exit
due to the way dialog updated stdin).
+ restore default value (a tab) for --separator or --separate-widget
lost in 2003/11/26 changes (Debian #326918).
+ make several widgets handle SIGWINCH (calendar, checklist, formbox,
fselect, inputbox, menubox, pause, tailbox, textbox, timebox). Only
msgbox and yesno had been done before. Note that some still have
fixed geometry requirements, so they cannot be shrunk below a given
threshold. Also, these changes do not address traversal, e.g., for
tailboxbg.
+ make gauge widget handle SIGWINCH with ncurses (Debian #305705).
+ add configure option to control whether largefile support is
compiled-in (Debian #298882).
+ update eu.po (Debian #312622, patch by Piarres Egana).
+ add/update po files from
http://www.iro.umontreal.ca/translation/maint/dialog/
fi.po, rw.po, sr.po, tr.po, zh_TW.po
+ fixes for configure script:
+ improve script for determining gcc version
+ improve checks for Intel compiler and related warning options
+ improve checks for defining _XOPEN_SOURCE (or alternatives) and
_POSIX_C_SOURCE
+ update config.guess, config.sub

2005/03/06
+ add/update po files from
http://www.iro.umontreal.ca/translation/maint/dialog/
ga.po, it.po
+ revert last change for da.po; it was from an older version (report by
Morten Brix Pedersen).

2005/02/06
+ modify makefile.in so --disable-echo applies to libtool builds.
+ corrected malloc size used for editable fields in formbox widget to
match the function which updates the corresponding buffer.
+ modify formbox widget's use of flen to allow negative values to be
used to limit the length of the displayed field.
+ improve description in manpage of output from formbox widget
(Debian #292418).
+ modify formbox widget to allow fields with flen==0 to display
(Debian #292417).
+ improved configure macros CF_POSIX_C_SOURCE and CF_XOPEN_SOURCE, to
avoid redefinition warnings on cygwin.
+ fix a typo in inputmenu-stdout found via "sh -n" (report by Steve
Grubb).
+ add/update po files from
http://www.iro.umontreal.ca/translation/maint/dialog/
ca.po, da.po, hu.po, nl.po, rm.po, ro.po, vi.po

2005/01/16
+ add --args option to help with debugging scripts.
+ adapted some new po files from Debian package for whiptail: ar.po,
bg.po, gl.po, hi.po, hr.po, mg.po, mk.po, ro.po, sq.po and zh_TW.po
+ update da.po (Morten Brix Pedersen).
+ add configure check for Intel 8.0 compiler, to set appropriate
warning options.
+ update config.guess, config.sub

2004/12/22
+ correct a typo in 2004/12/19 changes which caused width of multibyte
characters to be incorrectly computed in some locales.
+ modify --version and --help options to write consistently to the
standard output (report by Santiago Vila).
+ modify tailboxbg by resetting tty modes at the point where it forks a
process to update the screen, rather than waiting until that process
exits. This improves user feedback by making it apparent that dialog
is no longer processing input after that point (Redhat #142538).
+ minor updates to some .po files using Babel Fish, comparing with lynx.
+ update es.po (Santiago Vila).
+ work around bug in NetBSD 1.6 curses which seems to be confused by
reusing color pairs with different video attributes. The problem
does not appear in NetBSD 2.0 curses (but its headers do not provide
version info, so color-caching is not available for that
configuration).
+ modify pause and gauge widgets to ensure that reverse-video progress
bar is visible when the background is reversed, e.g., using the
default non-color attributes.
+ use chtype rather than attr_t, to build with old Solaris curses,
used in save/restore operation from 2004/09/20.

2004/12/19
+ add pause-widget (patch by Yura Kalinichenko).
+ modify exit-code returned on selecting the "Help"-button when the
--item-help option is given. Previously this returned the same code
as "OK", since it combines output for "OK" with the help status. It
now returns the help-code, but this can be overridden by setting the
environment variable $DIALOG_ITEM_HELP (reports by Erika Pacholleck
and Sebastian Muesch).
+ modify formbox widget so input-length is not limited to field-length
(report by David Liebermann).
+ localize the label on the search box for textbox widget (report by
Erika Pacholleck).
+ correct usage message detail for fselect, which listed an extra
parameter (Debian #284008).
+ add include for <sys/select.h> in ui_getc.c to build with QNX 4.25
using Watcom 10.6 (patch by Len Meakin).
+ modify behavior when no locale (or POSIX locale) is set to allow
legacy interpretation of Latin-1 character set (Debian #284795).

2004/11/18
+ correct computation of column width for menubox/checkbox tags, for
multicolumn characters, e.g., the menubox-utf8 example.
+ correct calls to wbkgdset(), which set the background attribute but
not the corresponding character (ncurses uses blank if none is given).
+ improve configure script check for _XOPEN_SOURCE and _POSIX_C_SOURCE.
+ improved limit-computation in show_message() to allow for scrolling
very long messages.
+ adjust scrolling logic in msgbox to account for the one-line offset
used by the logic which wraps text in a box, thus avoiding leaving
an extra blank line (report by Maxim Sobolev).

2004/09/20
+ add samples/whiptail.rc
+ add samples/dialog.py (noting that a later version of this exists
as pythondialog, but this is relatively self-contained). Modified
the script to accept the $DIALOG environment variable like the other
sample scripts, to specify the path of the program to use.
+ modify the install rule for header-files so the autoconf names in
dlg_config.h (and corresponding usage in dialog.h, etc), are altered
from "HAVE_xxx" to "DLG_HAVE_xxx", etc.
+ add a check for getenv("HOME") in rc.c
+ add a call to end_dialog() in signal_handler for tailboxbg (from
patch by Werner Fink).
+ correct initialization in checklist and radiobox for --default-item,
scrolling as needed.
+ modify --visit-items option so that it puts the cursor initially on
the list (in menubox, checklist and radiobox), accepts abbreviations
for the buttons when the cursor is on the button-row, and otherwise
(when --visit-items is given) abbreviations apply only to the list
(report by Erika Pacholleck).
+ modify a few widgets (inputbox, textbox, yesno) to beep on unexpected
input.
+ modify some msgbox widget to accept abbreviations of its button
label, for consistency with other widgets (request by Erika
Pacholleck).
+ corrected logic of dlg_char_to_button(), making it check only the
first uppercase letter in each button label rather than all uppercase
letters (report by Erika Pacholleck, cf: 2003/09/10).
+ improved description of --clear and --keep-window options (adapted
from Erika Pacholleck).
+ move discussion of --beep and --beep-signal options to Obsolete
Options section of manpage, remove these from the help-message
(report by Erika Pacholleck).
+ bracket extern's in dialog.h with C++ extern "C" declaration, in case
the library is used from a C++ application.
+ modify inputmenu examples to allow ESC to cancel the script.
+ modify inputmenu widget to cancel edit on a TAB or ESC.
+ modify inputmenu widget to use the same color scheme for the editable
text as the inputbox widget.
+ modify samples/killall to work around differences in "cut" versions.
+ use the color-caching from the \Z logic when loading the ".rc" file,
thereby reducing the number of color pairs required, and making it
less likely that deriving color pairs for drawing arrows on a given
background will run out of colors.
+ save/restore window attributes in dlg_draw_arrows() and similar
functions, to allow widgets to draw arrows using the widget's
background rather than a common/fixed value (request by Erika
Pacholleck).
+ modify textbox widget so the down-arrow will be hidden when at the
end of the file. (Modifying the up-arrow to be hidden is harder -
will do this when implementing scrollbars).
+ correct off-by-one in fselect.c which left down-arrows showing at
the bottom of directory- and file-lists (report by Erika Pacholleck).
+ improve display of percentages by omitting blanks where lines should
be shown.
+ modify logic for \Z escapes to make those that set video attributes
not clear the colors (report by Erika Pacholleck).
+ modify logic for \Z escapes to allow foreground and background
colors to be the same, provided that bold attribute is set.
Also improved the logic for choosing a background color when the
foreground and background are the same (report by Erika Pacholleck).
+ updated configure script macro CF_XOPEN_SOURCE, ensuring that the
_POSIX_C_SOURCE value is defined with a specific value (bug report
originally for lynx).
+ fix configure script so that po/makefile is generated properly when
the configure --srcdir --enable-nls options are used.
+ modify makefile.in to allow build/install from another directory,
i.e., using configure --srcdir (patch by Mike Castle).
+ updated da.po (Debian #262587, Morten Brix Pedersen).
+ modify some sample scripts to avoid using grave quotes nested within
double quotes with multiple file redirection, which does not work
with Solaris /bin/sh (report/analysis by Eric Haller).
+ check for end of string immediately after a \Z escape to avoid
displaying the null terminator as a ^@ (report by Erika Pacholleck).
> patches by Erika Pacholleck:
+ modify calendar.c, fselect.c and timebox.c to use color scheme like
other lists, using menubox colors rather than dialog colors.
+ correct charset for po/de.po, translate messages for "Help" and
"Rename".
+ omit parentheses around percentage in textbox.c
+ correct a few mismatched attributes, e.g., searchbox_attr in textbox.c,
percentage in msgbox.c,

2004/07/31
+ add test scripts to cover zero-width column case.
+ remove limit checks from checklist.c and menubox.c (cf: 2004/07/28),
since some scripts use zero-width columns (Debian #262411 and report
by Kyle Sallee).

2004/07/29
+ modify msgbox.c to only reserve space for percentage shown as part
of scrollable text for the msgbox widget. This makes infobox look
as it did before 2004/06/06 changes (report by Vinesh Christopher)

2004/07/28
+ remove redundant calls to wtimeout() from widgets since wtimeout()
is properly called from ui_getc() where it is controlled by the
--timeout option (bug report by juanjo).
+ add limit checks in checklist.c and menubox.c for very narrow screens
(prompted by Steve Grubb patch).
+ initialize step in dlg_draw_buttons() in case it is used to draw
a vertical list of buttons (prompted by Steve Grubb patch).
> fixes by Steve Grubb:
+ correct logic in checklist.c (cf: 2003/11/26 changes) which turned
quoting on unnecessarily for radiobox, breaking some old scripts.
+ increase size of array in dlg_ok_labels() to avoid overrun if extra
and help buttons are used (cf: 2002/06/22 changes).
+ initialize fkey variable in menubox.c and textbox.c (cf: 2003/07/12).

2004/07/21 - release 1.0
+ minor updates for configure script, i.e., CF_XOPEN_SOURCE,
CF_NCURSES_LIBS macros.
+ update config.guess, config.sub
+ add nl.po (Jacques Weewer).

2004/06/06
+ add --visit-items option, which allows the user to tab to the item
list in the checklist/radiobox and menubox widgets (request by
Ari Moisio).
+ use wide-character line-drawing for up/down arrows when configured
for wide-characters, gives better results with uxterm.
+ limit the number of times a --file option can be used, to prevent
runaway recursion if a --file option is embedded within a file which
is included.
+ improve discussion of wrapping in the manpage (Debian #251937).
+ modify msgbox to allow it to scroll vertically like textbox (Debian
#233276). This only works with ncurses.
+ implement $DIALOGVARS environment variable to apply common options to
dialog_vars when it is reset before processing other common options.
+ add --single-quoted option to control whether output is double-quoted
with '"' or single-quoted with single-quotes.
+ revert the default quoting behavior of checklists to use
double-quotes (report by Mark K Post regarding Slackware scripts).
+ add eu.po (Basque) (Piarres Beobide Egaa).
+ add ca.po (Catalan) (Jordi Mallach).

2004/04/21
+ add a call to flushinp() to init_dialog(), to discard any typeahead
before dialog is invoked (Debian #244746).
+ correct dlg_match_char() function, which was broken during rewrite
to support wide-characters (Debian #244777).
+ improved ru.po, uses UTF-8 charset (Leonid Kanter, Redhat #119200).
+ correct position of shadow drawn for dialogs, which appeared to work
for most versions of curses (other than NetBSD) but would have been
visible for certain color schemes (discussion with Julian Coleman).
+ correct loop-exit in longest_word() (Tomas Heredia, forwarded by
Santiago Vila).
+ add cy.po (Welsh) (Dafydd Harries).

2004/03/16
+ modify quoting of results to use single-quote rather than double
quote, and ensure that results containing a quote or backslash
character are escaped (report by Florent Rougon)
+ remove an incorrect comparison from checklist which made cursor
stick on the last line, from 2004/03/01 changes.

2004/03/14
+ add a dependency to install library if "--with-libtool" is used.
+ add manpage for the library.
+ add "--file"
+ modify formbox.c to support "--help-status" like menubox.
+ modify checklist.c to add item name to the "HELP" string when
"--help-button" is used and no --item-help option is given (Debian
#236841, report/patch by Jorg Sommer).
+ rename colors.h to dlg_colors.h, install that when the library is
installed.
+ add copyright notice to usage ("--help") message.
+ correct a missing bounds check for mouse-clicks in menubox (prompted
by Debian #233044).
+ updated several configure-script macros: AM_GNU_GETTEXT,
AM_WITH_NLS, CF_OUR_MESSAGES, CF_PROG_EXT, CF_WITH_DBMALLOC,
CF_WITH_DMALLOC, CF_WITH_LIBTOOL, CF_XOPEN_SOURCE.

2004/03/01
+ improve layout of calendar widget to allow for very long button
labels (report by Santiago Vila).
+ correct logic for $DIALOG_TTY, broken in 2003/11/30. The environment
variable must evaluate to a nonzero integer (report by Florent
Rougon).
+ document interaction between "--default-no" and "--no-cancel" options
in manpage (Debian #223488).
+ change configure script to use autoconf 2.52+patch, to work around
issues with Estonian locale (report by Seemant Kulleen).
+ add uk.po (Ukrainian) (Debian #232441).
+ make --default-item apply to checklist widget (Debian #225255).
+ correct a missing check for --item-help when --help-status was given
for checklist (Debian #232921).
+ correct a missing bounds check for mouse-clicks in checklist (Debian
#233044).
+ update config.guess, config.sub

2003/12/07
+ correct infinite loop in yesno widget when "--defaultno" option is
combined with "--no-cancel" (Debian #223077).

2003/11/30
+ suppress double-quotes added for "--help-status" option if the
string does not contain any special characters.

2003/11/26
+ add samples/sourcemage.rc, for comparison with slackware.rc
+ add "--insecure" option (request by Sean Mathews (DrWho@f34r.com)).
+ make "--defaultno" option apply to widgets which use OK/Cancel
buttons as well (Debian #209030).
+ improve documentation of exit-codes for each widget in the manpage
(Debian #217926).
+ add option "--keep-window" to suppress repainting after completing
each widget (request by Ingo van Lil).
+ add options "--yes-label" and "--no-label" to allow override of the
"Yes" and "No" strings (request by Christoph Zwerschke).
+ add option "--help-status" to allow script to restore a checklist
or radiolist after processing an item-help string (Debian #209031).
+ modify width-calculation for non-formatted text to ensure it is
wide enough for the longest word in the text (patch by Andrew Gaul).
+ modify dlg_index_columns() to count a newline as a single cell rather
than 2 for the normal curses case. This fixes an off-by-one for
the text-justification, shown in screen 2 of msgbox1 sample script.
+ fix dlg_char_to_button(); 2003/09/10 changes made it incorrectly
ignore case of the labels.
+ change calendar's use of arrow keys so they are (as before 2002/06/22)
interpreted within the day-grid as movement within that grid (request
by David Anders).
+ correct missing initialization of last_getc variable in dlg_getc()
(report/analysis by Victor Wodecki).
+ modify main program to make
dialog --no-shadow --print-maxsize
work. Normally dialog prints the screen size after subtracting the
area reserved for shadows, but some applications may need the actual
screen size (Debian #213424).
+ several related changes (Debian #213425):
+ separate the examples using "--stdout" and "--output-fd" from the
normal usage examples.
+ add "--input-fd" option, provide a sample of its use.
+ modify init_dialog() to use initscr() unless a "--stdout" option
was used. Some scripts relied on the coincidence that redirecting
standard output from dialog would "work". Before this change
init_dialog() assumed that redirected standard output was
synonymous with "--stdout" option (not the intended behavior).
+ modify command-line parsing to look for "--stdout" and "--stderr"
options first, allowing only one.
+ add a check for an environment variable $DIALOG_TTY which provides
the older behavior, i.e., try to open the terminal directly if
stdout is redirected.
+ interface changes, to make libdialog simpler to use:
+ rename all of the internal functions to begin with "dlg_", but
provide compatibility with older names if the application defines
__DIALOG_OLD_NAMES__.
+ add dialog_version() function, and corresponding DIALOG_VERSION and
DIALOG_PATCHDATE definitions to dlg_config.h
+ eliminate remaining global variables such as screen_initialized in
favor of dialog_state and dialog_vars.
+ move some data such as dialog_vars.output to dialog_state, since
they are normally not reset between widgets.
+ change interfaces of dialog_yesno() and dialog_checklist() to use
dialog_state.defaultno and dialog_vars.separate_output, making it
simpler and more consistent.
+ improve configure script and related definitions:
+ add "--with-libtool" option to provide shared library support by
libtool.
+ rename generated "config.h" to "dlg_config.h", so it can be
installed without naming conflict. Added "dlg_config.h" to
install-lib rule.
+ modify configure script and makefile to use EXEEXT and OBJEXT.
+ add "--enable-widec" option to control whether wide-curses features
are compiled-in, rather than check for the existence of those in
the curses library. This allows building with HPUX curses, which
has abandoned legacy features while not quite supporting X/Open
curses.
+ add configure check for getbegx(), etc., which are not provided on
all platforms.
+ update config.guess, config.sub

2003/10/02
+ update hu.po (Arpad Biro).
+ revert part of the 2003/08/18 change to "--stdout" option. Using
stderr for screen output does not work well on several platforms
since stdout's settings are affected (report by Kent Robotti).

2003/09/24
+ modify tailbox to allow it to display files with arbitrarily long
lines.
+ fix an infinite loop in tailbox, broken when making interface changes
to dlg_getc() (report by Ingo van Lil).
+ amend fix for "--and-widget" to not treat "---" as an option (report
by Kent Robotti).
+ updated es.po (Santiago Vila).

2003/09/10
+ correct "RENAMED" result from inputmenu widget, which did not reset
the result buffer, and did not account for scroll-offset (Debian
#209336).
+ modify button, menu and checklist logic that matches a character to
the beginning of a text field to support wide-characters (completes
Debian #195674).
+ modify configure script to not use "head -1".

2003/08/30
+ modify searchbox popup in textbox widget so one can simply press
return on an empty input to cancel the popup.
+ modify error reporting to avoid clearing screen if a problem is
found in the ".rc" file.
+ add color/attribute combinations for form widget (based on patch by
Reznic Valery).
+ combine rc-file colors, attribute- and color-tables to obtain a
single table for color values, which requires less work to add new
entries.
+ modify fselect widget to make back-tab work again, since it was
broken by the rewrite of dlg_edit_string().
+ modify howmany_tags() so it will quit searching when it finds any
option, not only "--and-widget" (Debian #206636).
+ correct call to dlg_print_text() in print_line(), which did not
account for hidden characters (report/patch by David Poole).
+ modify print_button() to display properly if locale defines ok/cancel
or yes/no buttons that contain multibyte characters.

2003/08/20
+ correct an indexing error when deleting from the end of a line using
KEY_DC; it happened to work on Linux because malloc() clears memory
like calloc().
+ add '\r' to case statement where '\n' is translated to KEY_ENTER to
work around defect in NetBSD curses.
+ modify configure check for getparyx(), etc., which are implemented
by NetBSD curses as functions rather than macros.
+ correct configure check for term.h, which may be <ncursesw/term.h>
if ncursesw development headers are installed, but not ncurses
development headers. Or they may not coincide (Debian #206287).

2003/08/18
+ modify checklist.c and menubox.c to display tags properly if they
contain wide-characters.
+ better solution for initializing curses when "--stdout" option is
used, e.g., use stderr for the output if it is a tty. Also correct
the error handling, so dialog exits with an error if it cannot
find a way to do output (Debian #205509).
+ modify sample scripts to use consistent definition of $DIALOG
(Debian #205508).
+ add UTF-8 examples inputbox6-utf8, inputbox6-utf8 (from Tomohiro
Kubota, Debian #195674).
+ modify print_line() to work with wide-characters, e.g., so it handles
wrapping for double-width characters.
+ cache results from multibyte character indices, speeds up cursor
movement.
+ modify form widget to support scrolling and mouse-selection.
+ add form widget (based on patch by Reznic Valery).
+ correct mouse-handling for inputmenu widget.
+ corrections to menu.c: location of clearing operation, and height of
rows in code for older ncurses versions (patch by Reznic Valery).
+ improve logic that compensates for xterm's alternate-screen by
cancelling the rmcup/smcup strings after the rmcup has been issued.
That ensures that dialog will not clear the screen on exit (report
by Javier Kohen).
+ modify initialization between widgets to retain the values for the
--aspect, --separate-widget and --tab-len options.
+ add --separator as an alias for --separate-widget (compatible with
Xdialog).
+ correct handling of Xdialog's --icon and --wmclass options, whose
parameter was not ignored.
+ correct logic for --separate-widget so its string is written before
each output, rather than only for --and-widget option (report by
Javier Kohen).
+ improve limit-check in center_label() for buttons.c (report by Tor
Vidar Havstad).
+ correct layout of --menu widget, which reduced display width due to
logic for --inputmenu being applied whether or not that configuration
was used (reports by Javier Kohen, Dimitar Zhekov and MAL
<mal@komcept.com>). Fixes Debian #201215.
+ modify gauge widget to support --begin option (Hans-Joachim Baader).
+ updated pl.po (Jaroslaw Swierczynski).
+ hide cursor while painting gauge.
+ add auto-sizing logic to gauge widget (reports by Javier Kohen and
Robert Schubert).

2003/07/20
+ rewrote inputstr.c, allowing it to enter and display wide-characters.
Some nonprinting characters such as control/B can be edited as well.
+ modify timebox to allow user to type numbers into the fields.
+ change interfaces of dlg_getc(), mouse_wgetch(), etc., to add
parameter that returns whether the result is really a function-key.
This is needed to work with wide-character curses.
+ correct computation of week-number in calendar widget (report by
Heiner Lamann).
+ updated configure script macros:
+ suppress -Winline with gcc 3.3, since it is broken.
+ fix caching bug in CF_UTF8_LIB
+ improved script for CF_BUNDLED_INTL.
+ update config.guess, config.sub

2003/03/08
+ add null-pointer checks to some malloc calls which were overlooked.
+ correct logic in dlg_add_result(), which did not copy content of
non-allocated buffer to the first allocation (report by Daniel
Dupont).

2003/03/02
+ correct an uninitialized value in dlg_add_result() (Debian #182683).

2003/01/30
+ corrected print_line(), which subtracted the margin twice from the
right-limit, making a string wrap unnecessarily (Debian #168823).
+ correct initial limit-check for arrows in checklist.c, which used
the wrong variable, showing the bottom arrow when it should not
(Debian #168823).
+ modify driver to always call show_result(), to simplify updates.
+ fix several memory leaks, important if dialog is run with a large
number of widgets (report by albert.veli@telia.com forwarded by
Santiago Vila).
+ check if the screen output is actually to the terminal before trying
to suppress xterm's alternate screen mode (see 2000/01/18) (report by
David Oliveira).
+ use dialog_vars.input_result consistently to return the text which is
printed after a widget completes. In many cases, dialog now
allocates enough space to hold the text, rather than use a fixed
buffer. The checklist widget was writing directly to the output to
avoid limits of the fixed buffer.
+ modify dialog.c to also write dialog_vars.input_result if the
Help-button was pressed (request by Amon Ott).
+ add hu.po (Arpad Biro).
+ update fr.po, pt.po, pt_BR.po to add strings for "Help" button (patch
by Frederic L W Meunier).
+ fix off-by-one error in menu.c, checklist.c (reported by
Tomasz Wasiak 2002/09/15 and others:
Andrew Gaul 2002/11/12,
Tobias C Rittweiler 2002/11/19,
Arpad Biro 2003/01/21).
+ updated configure script, improving checks for ncurses in various
locations, updated NLS script to match lynx. Added --with-curses-dir
option.
> Tobias C Rittweiler:
+ make ifdef in mousewget.c consistent with usage in dialog.h
+ use beep() rather than flash() in dlg_edit_string(), for consistency
with the other functions.
+ change order of buttons so extra button falls between Ok/Cancel.
+ fix so "dialog --print-maxsize" exits from curses.
+ add --inputmenu option.

2002/08/14
+ modify checklist.c and menubox.c to treat the extra button like the
"Ok" button by making dialog print the chosen items (request by
Tobias C Rittweiler).
+ add examples checklist6 and menubox6 to illustrate the --colors
option.
+ implement -colors option, which allows one to highlight words in the
titles and most text areas with color or video attributes (adapted
from patch by Tobias C Rittweiler).
+ add examples inputbox4, inputbox5 to illustrate how to use the
--output-fd option, and how to use dialog without any temporary
file at all.
+ add --output-fd option (Debian #153984).
+ documented vi-style keys for calendar, textbox widgets in manpage.

2002/06/22
+ improve mouse handling, e.g., for up/down scrolling in calendar,
checklist, etc.
+ add --extra-button and --extra-label options (adapted from patch
by Tobias C Rittweiler).
+ correct displayed cursor position in inputbox when returning to the
input area after traversing the buttons with tabs, etc.
+ add left/right arrows for traversal in calendar and timebox dialogs.
+ implement two new functions dlg_next_ok_buttonindex() and
dlg_prev_ok_buttonindex(), using these to hide details about the
traversal over buttons in several widgets.
+ modify checklist.c and menubox.c to verify if both --help-button and
--item-help are specified before assuming that selecting the help
button should cause the "HELP {item-help}" message to be printed
(reported by Marcel Ritter).
+ modify init_dialog() to work around HP's broken tty driver (report by
John Mudd). Specifically, the problem is that when opening /dev/tty
directly (to support the --stdout option), the terminal does not
change to raw mode. The workaround opens /dev/tty only as needed;
the --stdout option does not work on HPUX but otherwise dialog works.
+ updated el.po (patch by kromJx <kromJx@crosswinds.net>).

2002/05/19 - release 0.9b
+ add --no-collapse option to allow one to retain tabs and repeated
blanks in a message box (request by Roberto Simoni).
+ use DLG_EXIT_ESC constant rather than -1's in several places. This
has the effect of changing some exit-with-error cases to denote that
the exit was because ESC was pressed (patch by Diego Alvarez,
forward by Santiago Vila).
+ bump package version to 0.9b (with patch-date, as usual).
+ add --exit-label option (request by Roberto Simoni).
+ updated de.po to correct translation for "Cancel" (from Michael
Piefel, Debian #146402).
+ use definitions from autoconf macro AC_HEADER_TIME to ensure that
time() is properly prototyped.
+ update pl.po, adding translation for "Help" (patch by Jaroslaw
Swierczynski <swiergot@hacking.pl>).
+ update COPYING file, to reflect address change of FSF (reported by
Santiago Vila).
+ update some configuration script macros: CF_CHECK_CACHE,
CF_CURSES_CPPFLAGS, CF_HEADER_PATH and CF_MAKEFLAGS.
+ correct misuse of "$with_XXX" variables in the configure script,
which prevented configuration against curses library as opposed to
ncurses.
+ update config.guess, config.sub

2002/03/09 (a)
+ modify geometry of samples/fselect scripts to allow them to run in
a 24x80 screen (report/patch by Santiago Vila).
+ correct exit-code for menubox.c when Cancel is pressed. This was
unintentionally altered when adding --help-button (reported by
Patrick J Volkerding)

2002/03/09
+ add --timeout option, which forces the program to exit with an error
if no user response is given within the specified number of seconds
(request by <andrew@argoncorp.com>).
+ modify calendar widget to allow day/month/year values to default to
the current date (request by <Ron.Perrella@bellsouth.com>).
+ modify display of buttons in checklist.c and menubox.c to handle the
case where the button label is empty (Debian #134388).
+ extended logic for ok/cancel/help to make this work with checklist
widget.
+ revert pt_BT.po, apply changes to pt.po (report by Frederic L W
Meunier).
> several changes from Stanislav Ievlev:
+ add options --help-button and --help-label to make menubox display a
third button which can be used to return an exit code causing the
calling script to show extended help information.
+ use home/end keys in input string-editing, e.g., inputbox.
+ add option --max-input to limit length of string returned by inputbox
and other widgets which allow the user to edit a string.

2001/12/02
+ add --ok-label and --cancel-label options (request by Kyle Sallee).
+ correct usage message for --fselect option (reported by Patrick J
Volkerding).
+ add samples/debian.rc, for comparison with slackware.rc
+ corrected samples/slackware.rc, which was just the compiled-in
default values (patch by Patrick J Volkerding).
+ modify search rule for rc-file to add a global rc file /etc/dialogrc
(patch by Patrick J Volkerding).
+ updated pt_BR.po with modified entries for fselect.c (Frederic L W
Meunier).
+ add pl.po (Swiergot <swiergot@l02.ids.czest.pl>).

2001/11/11
+ modify command-line parsing to allow a "--" argument to act as an
escape, so the next argument is not recognized as an option if it
begins with "--". This is apparently one of popt's undocumented
features, upon which some Debian scripts depend (Debian #116642).
+ add da.po (Morten Brix Pedersen <morten@wtf.dk>).
+ add an install-strip rule to makefile, changing the normal install
rule to not strip the installed executable (based on discussion with
Santiago Vila).
+ initialize my_output variable if user cannot open /dev/tty, e.g., if
su'd to another user (patch by Richard Braakman (<dark@ssh.com>), Debian
#117177).
+ add configure option --with-ncursesw, to allow configure/build with
wide-character version of ncurses.

2001/10/14
+ add option --ignore, to make dialog be ignore options that it does
not recognize.
+ add option --trim, to trim literal newlines and repeated spaces from
text that will be displayed. Add samples/msgbox2, which is the
same as msgbox1, but using --trim (cf: change for Debian #102942).
+ minor correction to attributes for buttons.c to use active_attr on
the right-side of a button.
+ add a sample dialog rc-file slackware.rc based on diffs in hdasetup
package at
http://ftp1.sourceforge.net/pub/mirrors/slackware/slackware/source/a/hdsetup/
(discussion with Frederic L W Meunier).
+ modify dialog.pl to avoid using a statically-named tempfile, allowing
multiple processes to use this script (patch by James Ranson
(<euclid80@yahoo.com>), Debian #110609).
+ correct fprintf() call in j_menu() function, i.e., "--menu" option,
which did not guard against expanding '%' embedded in the parameters
(Stavros Chatzistefanidis <sxatz@yahoo.com>).
+ add et.po (Ivar Smolin <okul@trenet.ee>).
+ update fr.po (Frederic L W Meunier).
+ modify to allow scripts to alter the exit codes, mainly to
distinguish ESC and ERROR exits. This is done by setting a shell
variable such as DIALOG_ESC to a new value (request by Petr Vandrovec
(<vandrove@vc.cvut.cz>), Debian #99264)

2001/08/27
+ use VPATH in makefile to support build with configure --srcdir, if
the make program supports that. Note that samples/install/makefile
is not generated, due to awkward limitation of autoconf script
(reported by Frederic L W Meunier <0@pervalidus.net>).
+ add po/pt_BR.po (Frederic L W Meunier <0@pervalidus.net>).
+ correct sense of --enable/--disable shown in configure --help (report
by Frederic L W Meunier <0@pervalidus.net>).
+ correct logic for --clear option, broken in 2000/07/02 (fixes Debian
#110254).

2001/08/11
+ porting fixes to work on AIX: flush output to work around bug in
curses library, use ./killall in scripts to avoid conflict with
AIX program by that name.
+ modify dlg_trim_string() to retain literal newlines if the string
does not contain "\\n" strings, and to retain leading blanks on the
resulting lines, for compatibility with older scripts (Debian
#102942).
+ add charset specification to cs.po
+ change dates in CHANGES to consistent format, add el.po for Greek
(patch by kromJx <kromJx@crosswinds.net>).
+ eliminate static globals (bss, data) from modules rc, tailbox,
textbox using better parameter-passing convention, and const.
+ cleanup temporary files in a few of the sample scripts.
+ rewrote tailboxbg using select() rather than fork(), thereby
eliminating lock-files. Only one process should be trying to display
on the screen at any given time.
+ add error check to ensure that numeric parameters are really numbers.
+ correct off-by-one in error messages reporting too-few or too-many
tokens for a given option (reported by George Mirchev).
+ fix typo in manpage, "textboxbg" where "tailboxbg" was meant
(reported by George Mirchev <la@mail.techno-link.com>).
+ use DLG_EXIT_xxx symbols consistently for all exit codes.
+ updated es.po (patch by Santiago Vila).
+ updates for some configure script macros from lynx: CF_MAKEFLAGS,
CF_NCURSES_VERSION, CF_PROG_EXT.
+ fixes to compile if <term.h> is included, e.g., when building with
AIX curses (report by Suzi Dowson <Suzi.Dowson@capgemini.co.uk>).

2001/05/27
+ updated dialog.pot
+ modify fselect.c to work with autosize, i.e., given height and width
zero (report by Martin Povolny).
+ add a null-pointer check in justify_text(), needed by fselect.c
+ add several more options which dialog can safely ignore, from
Xdialog 2.0.2
+ refinements for configure macros checking for $CPPFLAGS, from lynx.
+ update config.guess, config.sub to match autoconf 2.50
> Martin Povolny <martin@solnet.cz>:
+ add cs.po
+ use nl_langinfo() to customize names for day-of-week, and month

2001/05/11
> Vincent Stemen <dialog@AdvancedResearch.org>:
Fixed dialog.c to not pass menu items through dlg_trim_string().
Stripping extra spaces out of the menu items broke some of my
scripts by altering the string that it compared to know which menu
item was selected. There should be no need to do justification on
the menu items, which are always one line, anyway.

2001/04/29
> Vincent Stemen <dialog@AdvancedResearch.org>:
+ rewrote the text justification code to be able to have preformatted
text in the prompts with extra spaces like the older versions of
dialog. If there are "\n" strings in the text, then extra spaces are
preserved. Lines are always wrapped on word boundaries.
+ fixed --cr-wrap to break lines on '\n' (newline) characters and not
add an extra line at the top and bottom of the text. It now works
as the manual says it should.
+ it is no longer necessary to use "\n\" at the end of lines to escape
the '\n' character. "\n" now works. However, the old way, "\n\"
still works.
+ the fixes involved the following changes:
- rewrote dlg_trim_string() to recognize preformatted text (know
when not to strip extra spaces) and to pay attention to --cr-wrap.
- rewrote justify_text() which now calls a new function in util.c,
print_line(), to print each line and end it on a word boundary.
- modified real_auto_size() to call a new function
auto_size_preformated() to calculate the box size for preformatted
text.
- removed skip_blanks() and skip_text() since they are not used by
the new justify_text().
- modified dialog.c to not call dlg_trim_string() on title strings
so that titles retain their spaces.
+ modified the following demo files in the sample directory:
- inputbox
changed all "\n\" strings to "\n" to demonstrate the extra
backslash is no longer needed.
- inputbox1
removed all the "\n\" strings from the end of the lines to
properly demonstrate --cr-wrap.
- msgbox1
this sample was using "--aspect 9 --cr-wrap". Rewrote it to
properly demonstrate --aspect. 9 is already dialog's default
aspect ratio. It now creates several dialogs in sequence,
demonstrating aspect ratios of 9, 12 and 6 and properly
demonstrates --cr-wrap.
+ made the following changes to the manual (dialog.1).
- rewrote the description of --aspect to be more understandable.
- rewrote the description of --cr-wrap to be more correct and more
detailed. It did say, "Otherwise, the text for each dialog will
display on a single line.", which is not correct. It wraps the
text to fit in the box.
> T.Dickey:
+ use logic from menubox dialog in checklist to handle autosizing when
list height is given as zero (fixes problem reported by Eric Veltman
<eveltman@baan.nl>).
+ modify checklist and menubox dialogs to check for too-wide data, and
truncate one or both of the name and text fields to fit (also
reported by Eric Veltman).
+ corrected a few items from Vincent's patch:
- use C89-style comments rather than C++
- restore logic in justify_text() which checks for win==0, needed to
work with standard curses implementations other than ncurses.
The first call on justify_text() passes a null pointer as a flag
to indicate that checking should be done, but no screen updates.
- avoid modifying the buffer in decode_percent(), otherwise a message
containing a space or newline would be truncated at the whitespace.
- modify dlg_button_x_step() and dlg_button_layout() slightly to
work with altered print_autowrap(), etc.
+ fixes to build/work with SunOS 4.x 5lib curses

2001/04/15
+ fix a memory leak in mouse_region().
+ simplify handling of optional parameters with new functions
optional_str() and optional_num().
+ add calendar and timebox dialogs (compatible with Xdialog).
+ correct typo in fallback definition for getparyx, and remove void
cast for mouse_open and mouse_close which prevented build with
Sun's Solaris compiler.
+ rename --enable-lxdialog configure option to --enable-Xdialog
+ modify CF_NCURSES_CPPFLAGS macro to match more variations of ncurses
header files.
+ update config.guess, config.sub
+ modify some configure script macros to avoid problems with buggy
autoconf 2.49c which breaks changequote().

2001/01/15
+ small fix to revised real_auto_size() and justify_text() to avoid
adding origin to box-width, which broke samples/wheel.
+ apply 1999/12/25 tempfile change to wheel and copismall samples.
+ add sample script for tailboxbg.
+ revised lock-file management to better ensure that locks are actually
created by the tailbox subprocess(es).
+ correct hardcoded signal 15 in tailbox to SIGHUP to match
documentation. Signal 15 is usually SIGTERM, which cannot be caught.
+ correct off-by-one comparison of return-value for arg_rest() which
made
dialog --gauge test 10 50
dump core because it expected a 4th parameter (fixes Debian #80641).
+ resync config.sub, config.guess from
http://subversions.gnu.org/cgi-bin/cvsweb/config/ (which finally have
cases for OS/2 EMX), minor tweaks to related configure script macros.

2000/12/17
+ restore treatment of predefined height/width in real_auto_size()
which was lost in 2000/12/12 rewrite (report by Raphael Halimi
<raphaelh@easynet.fr>).
+ updates for configure script macros AM_PATH_PROG_WITH_TEST,
CF_CURSES_LIBS, CF_LIB_PREFIX, CF_PROG_EXT for $PATHSEP and $CFLAGS
fixes.

2000/12/13
+ correct change for create_lock(), which resulted in an infinite loop
(patch by Chris Butler, <chrisb@debian.org>).

2000/12/12
+ rewrote print_autowrap() and real_auto_size() to share common code
justify_text(), which now does text flow even when the string
contains newlines (fixes Debian #77199).
+ improve create_lock() function using open() with O_EXCL rather than
fopen() (patch by Matt Kraai (<kraai@debian.org>), Debian #78951).
+ correct description of --fselect in man page (patch by Tomas Pospisek
(<tpo@spin.ch>), Debian #77200).
+ add --no-cancel as alias for --nocancel for compatibility with
Xdialog (report by Luis E Limon <luisl@abriasoft.com>).

2000/10/27
+ some lint fixes using lclint (mostly void-casts, but some
sign-extension fixes e.g., for ctype.h macros, and loop in
dlg_char_to_button()).
+ modified to build/run on OS/2 EMX with ncurses.
+ minor changes to po/*.po (trim trailing blanks, provide explicit
translation for "OK"), to work with Solaris gettext.
+ modified to allow this to build with archaic version (1.8.6)
of ncurses on FreeBSD 3.1 (does not run).
+ update config.guess, config.sub from subversions.gnu.org

2000/10/17
+ use new function sub_window() to check success/failure of calls to
subwin(), printing an error message if it fails (fixes Debian #74903).
+ use combination of isatty/ttyname to look for workable tty device
on systems which have no /dev/tty, e.g., BeOS.

2000/10/08
+ change exiterr() to use stdarg.h, make some messages easier to
understand.
+ add dialog_clear()
+ make samples/install/setup build.
+ implemented mouse support for buttons, e.g., in yesno dialog using
ncurses (the gpm support no longer works, but is useful for reference)
+ add a configure check for chtype.
+ updates for configure script macros (CF_BUNDLED_INTL, CF_CURSES_LIBS,
CF_GCC_ATTRIBUTES, CF_GCC_WARNINGS, CF_INCLUDE_DIRS), and scripts
config.guess, config.sub
+ cleanup of item-help change, integrate with checklist and radiobox.
+ add ja.po, from Hirofumi Takeda <takepin@turbolinux.co.jp>.
> patch by Marco Mariani <marcom@sferacarta.com>
+ add --item-help option, which makes menubox data interpreted as
3 columns rather than 2. The third column is displayed on the
last line of the screen as a help/status message for the currently
selected item.
+ add it.po, pt.po
+ change TAG_KEY_HL to FALSE, making unselected items in checklist
easier to read on Linux console.

2000/07/30
+ change real_auto_size() to allow it to be used for dialogs that have
no prompt, e.g., fselect. Also, rather than requiring both height
and width to be given as -1 for maximizing the dialog, allow either
alone.
+ increase minimum height needed for autosized yesno dialog.
+ add --version as an alias for --print-version.
+ fix for build on Solaris without NLS (cannot redefine 'gettext()').
+ add fselect dialog (compatible with Xdialog).
+ add --enable-lxdialog configure option.
+ use new configure macro CF_ARG_MSG_ENABLE to show progress with
enable/disable switches.

2000/07/02
+ implement --stdout and --stderr options as in Xdialog.
+ move logic that translates "\\n" into '\n' into main program to
simplify logic that formats text.
+ make ifdef's for rc-file not specific to ncurses.
+ correct logic making percent parameter of gauge optional.

2000/06/29
+ add alternate test-script for gauge, adapted from Xdialog.
+ modify gauge to make optional a percentage which was read at the
beginning of the XXX-delimited message text, since clones of dialog
are written to assume this is text. If the line is not a simple
integer, dialog will treat it as text.
+ make the percent parameter of gauge optional, as in Xdialog.
+ undo one use of CharOf() in guage.c, an error.
+ fix configure macro AM_WITH_NLS to refrain from attempting to make a
symbolic link into/libintl.h if we are not using the bundled intl
directory from gettext (reported by Julian Coleman
<J.D.Coleman@newcastle.ac.uk>).
+ add ru.po, from Michael Sobolev <mss@transas.com>
+ updates for config.guess, config.sub from tin.
+ updates for configure script macros: CF_MATH_LIB (improperly nested
brackets/parenthesis) and CF_XOPEN_CURSES (make include of
<*curses.h> depend on configure tests).

2000/04/25
+ repaint screen when a control/L is pressed.
+ apply CharOf() macro to avoid sign-extension on calls to waddch(),
fixes a problem with accented characters (reported by Santiago Vila).
+ add es.po, from Santiago Vila <sanvila@unex.es>

2000/04/23
+ modified to use gettext (configure option --enable-nls). This uses
gettext 0.10.35, which must be previously installed. (It can also
use an included intl library, but I consider that to be a waste of
disk space).
+ remove code in checklist/radiobox, menubox that try to use
abbreviations for the OK/Cancel buttons since those conflict with the
check for abbreviations in list entries, which are more useful.
+ moved padding of button labels out of string literals, into the
logic of dlg_draw_buttons().
+ resync/update with configure macros CF_CURSES_LIBS, CF_FIND_LIBRARY,
CF_HEADER_PATH, CF_LIBRARY_PATH and CF_NCURSES_LIBS, as well as
mkdirs.sh and config.guess.

2000/02/22
+ add --default-item option, for menubox to set the default selection
(fixes Debian #49796).
+ add sample scripts for --nocancel and --fb options with inputbox.
+ modify inputbox* sample scripts to show application errors, if any.
+ add --nocancel option, and ignore --noitem, --fb, --fullbutton, to
make this compatible with whiptail scripts. (whiptail does not
handle many dialog scripts however).
+ modify checklist/radiobox to handle home, end, nextpage, prevpage
keys, as well as make the abbreviation search work for the whole
list, not only the current page.
+ treat KEY_LL the same as KEY_END in checklist and textbox.
+ add logic for KEY_BTAB.
+ use new function dlg_draw_buttons() to better manage the layout of
yes/no/ok/cancel buttons.
+ another pass of cleanup of dialog.c, makes it use a single table for
lookup of option names and help-message. Eliminated numerous
adjustments to 'offset' variable.
+ on initialization, check if standard input is from a terminal. If
not, open /dev/tty (fixes Debian #57771)

2000/02/05
+ implement inline editing in textbox.c search dialog.
+ revise inputbox.c, allowing inline editing with arrow-keys. removed
redundant logic in that module.
+ correct a typo that prevented rc-file configuration from building.
+ correct ifdef's to compile/run if the curses implementation does not
support color.

2000/01/23
+ improve test-case for gauge.
+ change gauge.c to show progress in reverse-video, add a check for
end-of-file in the loop for reading new messages.
+ use curses whline() function to simplify print_arrows() logic in
checklist.c and menubox.c
+ use curses beep() function rather than hardcoded strings.
+ correct several compiler warnings for gcc -pedantic (mismatch of
const, signed/unsigned).
+ modify exiterr() to avoid possible expansion of '%'.
+ change CF_MATH_LIB configure macro to allow specifying a particular
test-function. For dialog, this should be sqrt(). The macro was
originally written for ncurses, which needs sin(). However, that is
a builtin function on the m68k port (reported by Roman Hodek
<Roman.Hodek@informatik.uni-erlangen.de>, this fixes Debian #55553).

2000/01/18
+ update manpage (Debian #25648).
+ modify configure test for math library to avoid using a constant
parameter to the test function, lest gcc optimize the call away
(fixes Debian #55553).
+ restructure help-message so actual problem is indicated. The original
help-message is shown if no parameters are given, or if the --help
option is specified alone.
+ suppress xterm's alternate screen mode by sending an exit_ca_mode
after initscr if the terminal looks like xterm, e.g., has key_mouse
defined, and has private-mode escapes in both enter_ca_mode and
exit_ca_mode (fixes Debian #55181).
+ change yellow lettering on white to blue on white, since it offers
better contrast (fixes Debian #51196).
+ use napms() rather than sleep().
+ some cleanup/simplification of main program. Indent'd dialog.c and
util.c
+ eliminate several places where repeated options are treated as
an error, since they are really executed once anyway.

2000/01/15
+ remove pre-autoconf Makefile
+ remove sleep's from a few of the sample scripts, which left users
thinking that dialog was slow to complete an action.
+ rewrote infobox sample script, using dialog's --sleep option and
a loop in the script.
+ change 'ch' variable in tailbox.c to an integer, because it is
compared against EOF (fixes Debian #53157).
+ corrected mandir variable in makefile.in (reported by Santiago Vila).
+ small changes to sample scripts, from Debian: rename "guage" script
to "gauge", change path to copy of GPL used in textbox.
+ add uninstall rule to makefile.in, fixed some dependencies so
"make install" works without first doing "make all".

1999/12/25
+ use more portable scheme for tempfile generation in samples.
+ add a configure script, prefer to not use the original Makefile
because it works only with GNU make.
+ correct prototype of 'main()', which misused const.
+ modify guage.c to use fgets() rather than gets().
+ merge changes from Debian package maintainer
Santiago Vila <sanvila@ctv.es>:

1999/10/07
+ add a password dialog box (Debian #45964, patch by Joey Hess).
+ implement "--defaultno" option to specify if the default for
the yes/no box is "No" (Debian #46076, patch by Joey Hess).
1999/03/10
+ modify input.c to clear the input field to the right of the
given string, to help with screen-refresh
1998/12/08
+ check for list_height less than one in checklist.c (Debian
#22239).
1998/10/21
+ use function wscrl() in preference to scroll() in checklist.c
and menubox.c (unclear: in ncurses, scroll() is a macro that
uses wscrl()).
+ remove the "-I/usr/include/ncurses" option from Makefile
since Debian does not install ncurses' header files into
that directory.
1998/09/12
+ simplify menubox.c using new functions print_arrows() and
print_items(). add logic to handle KEY_NPAGE and KEY_PPAGE
(Debian #26326).
+ modifications to provide sample scripts (Debian #26211):
+ change sample scripts to use Debian tempfile utility rather
than putting files into /tmp.
+ change sample scripts to use 'dialog' from user's path
rather than in the parent directory as in the build
directory.
+ use the system copy of GPL rather than that in the build
directory as an example for the textbox script.

1999/11/27
+ fix some gcc warnings about ambiguous use of "else"

1999/05/01
+ cleaned up some of the redundant code with new functions:
box_x_ordinate
box_y_ordinate
draw_title
draw_bottom_box
new_window

+ modified msgbox.c and yesno.c to work with the KEY_RESIZE sigwinch
handling in ncurses 4.2

+ corrected spelling of "gauge"

The relevant portions of the Debian change log for the original version
(dialog-0.9a-12) are abstracted here, omitting details of their packaging:

1998/05/24

+ Replaced guage.c by the one in dialog 0.6z, which is known to work.
Fixes Debian #18284: unstable dialog.

1997/12/16

+ dialog.c: dialog_input_result printed with "%s" format. This was
Debian #9913, fixed by Bill Mitchell, but the change was lost.
+ Pristine source, .depend is not removed in clean target. Instead, it
is made zero length (otherwise it would not work *without* fakeroot).
+ Added '^U' support in input box (Debian #9915, patch by Joey Hess).
+ Wrote patch to fix core-dumping problem (Debian #13170). Sven Rudolph
