NAME

       adacursesw6-config - configuration helper for AdaCurses libraries

SYNOPSIS

       adacursesw6-config [--cflags] [--libs]

       adacursesw6-config --version

       adacursesw6-config --help

DESCRIPTION

       This  program  development  aid  simplifies  the process of configuring
       applications to use the AdaCurses library binding to ncurses.

OPTIONS

       --cflags   reports the GNAT (Ada compiler) flags needed to compile with
                  AdaCurses.

       --libs     reports the GNAT libraries needed to link with AdaCurses.

       --version  reports  the  release  and  patch  date  information  of the
                  ncurses libraries used to configure and build AdaCurses  and
                  exits successfully.

       --help     issues a usage message and exits successfully.

       Omitting options implies "--cflags --libs".

EXAMPLES

       Consider a program using AdaCurses to write the message "Hello, world!"
       in the center of the screen and wait for the user to press the "q"  key
       before exiting.  Populate a file hello.adb with the following.

           with Terminal_Interface.Curses; use Terminal_Interface.Curses;

           procedure Hello is
              Visibility : Cursor_Visibility := Invisible;
              Message : constant String := "Hello, World!";
              done : Boolean := False;
              c : Key_Code;
           begin
              Init_Screen;
              Set_Echo_Mode (False);
              Set_Cursor_Visibility (Visibility);
              Set_Timeout_Mode (Standard_Window, Non_Blocking, 0);

              Move_Cursor (Line => Lines / 2,
                           Column => (Columns - Message'Length) / 2);
              Add (Str => Message);

              while not done loop
                 c := Get_Keystroke (Standard_Window);

                 case c is
                     when Character'Pos ('q') => done := True;
                     when others => null;
                 end case;

                 Nap_Milli_Seconds (50);
              end loop;

              End_Windows;

           end Hello;

       Then, using
           gnatmake `adacursesw6-config --cflags` hello \
               -largs `adacursesw6-config --libs`
       or, more simply,
           gnatmake hello `adacursesw6-config`
       you can compile and link the program.
