sudo ninja install -C build

Compilation

valac --pkg pluie-echo-0.1  main.vala -o echo

Docker

docker run --rm -it pluie/libecho

Usage

playing with colors

using Pluie;

int main (string[] args)
{
    var c1 = new Color(37, false);
    var c2 = new Color(204, true);
    stdout.printf ("[%s][%s]", c1.s ("oki"), c2.s ("cool"));
    return 0;
}

playing with ColorConf

compile main.vala

valac --pkg pluie-echo-0.1  main.vala -o echo

run ./echo

then, change in resources/echo.ini :

title      =  15,1,97
title_item = 220,1
title_sep  =  97,1

run echo again :

init OutputFormatter

using GLib;
using Pluie;

int main (string[] args)
{
    var of = Echo.init (true /* enable tracing */, "resources/echo.ini" /* optional config file */);
    Dbg.in (Log.METHOD);
    
    of.echo (
        // multiline string
        "\nsample echo\non multiple\nline", 
        // newline
        true,
        // indent all line
        true,
        // set color with Pluie.ECHO enum (listing all defined styles in echo.ini)
        ECHO.ACTION
    );
    ...

    Dbg.out (Log.METHOD);
    return 0;
}
