I was unable to make it display ansi colorized output in Lisp REPL despite this project claims.


The code seemingly doesn't do anything except setting a variable. However in my slime folder .emacs.d/elpa/slime-20170319.1601 doesn't seem to contain anything slime-repl-ansi-color could use.

It still works. You need to have the file in the contrib directory under .emacs.d/elpa/slime-20170319.1601, then do something like

(push 'slime-repl-ansi-color slime-contribs)

to enable it.

It interfaces with slime through the slime-repl-emit function.
