I’m actually writing a paper on concurrency and I’m using tons of Elixir code.

I’m using the listings package and created a definition for the Elixir lang.

Some things like atoms and module attributes don’t work quite like I would prefer, but it is better than creating images and pasting then all the time

Here’s the definition:

\lstdefinelanguage{elixir}{
	morekeywords={case,catch,def,do,else,false,%
		use,alias,receive,timeout,defmacro,defp,%
		for,if,import,defmodule,defprotocol,%
		nil,defmacrop,defoverridable,defimpl,%
		super,fn,raise,true,try,end,with,%
		unless},
	otherkeywords={<-,->},
	sensitive=true,
	morecomment=[l]{\#},
	morecomment=[n]{/*}{*/},
	morestring=[b]",
	morestring=[b]',
	morestring=[b]"""
}

And here’s the rendered result:

If you do not fear \write18 and have a recent version of pygments installed, you can use minted package.

I made some minor changes to this, and ended up with highlighted keywords. The only downside is that a keyword needs to be followed by a space to make the parser happy.

\lstdefinelanguage{elixir}{
    morekeywords={case,catch,def,do,else,false,%
        use,alias,receive,timeout,defmacro,defp,%
        for,if,import,defmodule,defprotocol,%
        nil,defmacrop,defoverridable,defimpl,%
        super,fn,raise,true,try,end,with,%
        unless},
    otherkeywords={<-,->, |>, \%\{, \}, \{, \, (, )},
    sensitive=true,
    morecomment=[l]{\#},
    morecomment=[n]{/*}{*/},
    morecomment=[s][\color{purple}]{:}{\ },
    morestring=[s][\color{orange}]"",
    commentstyle=\color{commentgreen},
    keywordstyle=\color{eminence},
    stringstyle=\color{red},
	showstringspaces=false,
}

I have put an entire minimal example online here: Elixir Listings Latex · GitHub

The rendered output looks as follows:
