epygments is a simple wrapper to Pygments to highlight source code from your erlang program.



You can install manually the python dependancies or use Pip:

$ pip install -r requirements.txt

to use compile epygments:

$ make

to create the doc:

$ make docs

then open index.html in the doc folder.

Use it:

For now epygments offers you 2 function that you can use in your application:

  • epygments:all_languages/0 : get all languages
  • epygments:highlight/2, epygments:highlight/3, epygments:highlight/4 : prettify the source code. See the reference doc for more informations.

Test it:

$ erl -pa ebin -pa deps/poolboy/ebin
Erlang R15B (erts-5.9) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]
