Saw a library recently which allowed you to color text, but it 
had an odd syntax.

Since I already had some code for coloring text in terminals, I 
made this (hackish, POSIX only) project during lunch break. It in 
action:

     import std.stdio : writeln;
     import termcolor;

     // Color → Green → Foreground
     writeln(C.green.fg, "Green text", resetColor);

     // Color → Red → Background
     writeln(C.red.bg, "Red background", resetColor);

     // only tested on macOS running zsh using 
iTerm2/Hyper.js/Terminal.app

Hope this helps those who are making CLI applications :^)

Clever idea!  Doesn't quite cover all the color features of newer
terminals, but good enough for basic coloring on the terminal.  Maybe
I'll steal your idea next time I'm looking for some terminal colors. :D

Maybe during another lunch break ;)

However, not sure if it's active anymore, but ConsoleD (by Robik 
and Adam D. Ruppe) has most Windows specific colors and 
attributes available. Maybe give that a look?

I've used Adam Ruppe's terminal.d to great effect in my CLI programs.
Highly recommended:

Well, the consoleD part I'm not sure about, but I still work on 
my terminal.d which includes cross-platform color support (among 
a lot more like mouse input, line editing, etc).

Your api is not compatible with old Windows, but newer versions 
of Windows support the same esc sequences linux uses - though I 
think you have to opt into it with a console api call. (I might 
be adding support to this to terminal.d but eh i already have the 
features in there)

Maybe the documentation, in trying to be exhaustive, hasn't 
showed how simple it can be. I'm not sure why it is perceived as 
odd. Can you clarify?


 Since I already had some code for coloring text in terminals, I 
 made this (hackish, POSIX only) project during lunch break. It 
 in action:

     import std.stdio : writeln;
     import termcolor;


import textattr;


     // Color → Green → Foreground
     writeln(C.green.fg, "Green text", resetColor);


       writeln(ta("green"), "Green text", ta("off"));

*or* the shorter:

       writeln(ta("g"), "Green text", ta("f"));

*or* the even shorter:

       tawrite(" g", "Green text", " f", '\n');

The   indicates that it is an "at"tribute.

It's not an issue to add a tawriteln which adds the newline at 
the end. I first posted the basic library thinking to make 
additions as per demands later.


     // Color → Red → Background
     writeln(C.red.bg, "Red background", resetColor);


       tawrite(" /red", "Red background", " off", '\n');

The / indicates that it's a background colour. This is stated in 
the HTML documentation, but maybe not clear within the 
limitations of the README.md. I'll see what I can do to improve 
it.

Having premade symbols in the library as you have done is easy 
enough for basic 16-colour or even attribute support, but adding 
256 colour or true colour support this way would unnecessarily 
use up too much memory.
