  • Bold text (in terminal) from Ada?

    From reinert@21:1/5 to All on Tue Oct 11 01:06:42 2022
    Any simple way to print out bold text from an Ada program?
    In case, how?

    Assume linux.

    Print the corresponding ANSI control sequence to turn on bold mode
    before you print the text, then print the ANSI control sequence to turn
    off bold mode.

    See https://www.linux.org/threads/ansi-codes-and-colorized-terminals.11706/.

    Example:

    with Ada.Characters.Latin_1;
    with Ada.Text_IO;
    procedure Be_Bold
    is
    use Ada.Characters, Ada.Text_IO;
    begin
    Put ("This is a very ");
    -- Bold mode:
    Put (Latin_1.ESC); Put ("[1m");
    Put ("bold");
    -- Normal mode:
    Put (Latin_1.ESC); Put ("[0m");
    Put_Line (" program.");
    end Be_Bold;

    Looking at PragmARC.Ansi_Tty_Control (https://github.com/jrcarter/PragmARC/blob/Ada-12/pragmarc-ansi_tty_control.ads)
    we can see that sending

    PragmARC.Ansi_Tty_Control.Bold_Mode

    to most Linux terminal emulators initiates bold mode.

    Totally depends on what device you are printing to.

    Others have posted solutions for terminals that respect certain control
    codes.

    If you are printing to paper or a pdf file, you'll need to use some
    typesetting program like latex or Open Office document.

    Assume linux.

    Not enough information.

    No partly general solution?

    Another candidate is GNATCOLL.Terminal
    It supports the ANSI sequences and the Windows historical terminal (the newer Windows Terminal supports the ANSI sequences)

    If you're using Alire, try Mosteo's ansiada crate. Add it to your own project with `alr with ansiada`. See https://ada-lang.io/ to get started.
