ANSI colorization helper functions for Clojure programs.

You can call (clansi/style-test-page) to see what colors and styles are supported by your terminal.

Wrap strings in ANSI color and style codes like this:

(style "foo bar" :red)

(style "foo bar" :underline)

(style "foo bar" :blue :bg-red :underline)

You can turn the production of ANSI codes on or off by rebinding the clansi.core/*use-ansi* variable at runtime. This allows you to maintain only one version of your code with the strings marked up for color, and then turn ANSI on or off as desired, according to the properties of each output device, user preference, execution context, etc.

(without-ansi) and (with-ansi) convenience macros are provided for this purpose:

(defn print-colorized [] 
 (println (style "foo bar" :red)))

(print-colorized) ;; prints "foo bar" in red
(without-ansi (print-colorized)) ;; prints plain "foo bar", without any ANSI color codes
(without-ansi (with-ansi (print-colorized)) (print-colorized)) ;; prints a red "foo bar", then a plaintext "foo bar"

Bonus Features

  • call (clansi/colorize-docs) to make doc colorized
  • also supplies the color-doc macro, a stylized version of doc
