Erlang literate programming

gistfile1.txt

Simple literate programming.

Add comments to your Erlang file with a special %%% syntax, like this:

%%% This is a comment that will be formatted in a variable width font with Markdown.
%%% You can use *emphasis* and
%%% # Headings
%%% and even
%%%
%%% - Lists
%%% - of
%%% - things
%%%
%%% while the rest of the code is formatted like normal.

Then format the file by using sed to convert to Markdown and pandoc to convert to PDF:

sed -E -e 's/^/    /g' -e 's/^    %%% ?//g' | pandoc --toc -o listing.pdf -
