tempera

Template based terminal coloring made really easy.

Usage

Tempera allows to add coloring to terminal in a really easy way.

Colorize strings

To colorize strings, simply use the colorize function, passing a vector of styles you want to apply. The list of supported color names correspondes to the keys of CODES variable.

use tempera::*;

fn main() {
  println!("{}", colorize("Colorized", &["red"]));
  println!("{}", colorize("Colorized", &["red bgBlue"]));
}

Colorize templates

To colorize a template using a tagged template syntax, simply use the colorize_template function.

use tempera::*;

fn main() {
  println!("{}", colorize_template("{red}This is in red, {green underline}this in green underlined{-}, this in red again.");
}

The template recognizes styles between curly braces (use a single or double opening brace to escape them) and the token {-} as universal closing tag (which also restores the previous style).

The closing tag at the end of the string can be omitted, since tempera will append the global reset style (\u{1b}[0m) if any style was set.

If you want to discard styles to be restored, use the {reset} token.

Setting custom styles

If you want to define custom styles, use the add_style function.

use tempera::*;

fn main() {
  println!("{}", add_style("custom", &["yellow", "bgRed"]).is_ok());
}

256 and 16 millions colors support

tempera supports 256 ANSI codes and 16m RGB colors. Just give it a try:

use tempera::*;

fn main() {
  println!("{}", colorize("Colorized", &["ansi:100"]));
  println!("{}", colorize("Colorized", &["bgANSI:3,4,5"]));
  println!("{}", colorize("Colorized", &["rgb:255,0,0"]));
  println!("{}", colorize("Colorized", &["bgRGB:0,255,0"]));
  println!("{}", colorize("Colorized", &["hex:#FF0000"]));
  println!("{}", colorize("Colorized", &["bgHEX:00FF00"]));
}

ANSI, RGB, and HEX can be used in style definitions and templates as well.
