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