Elixir Setup

Elixir requires Erlang.

Building Erlang

On Windows, building on Cygwin seems possible but tedious.

Get precompiled binaries: https://www.erlang-solutions.com/downloads/download-erlang-otp

On Unixy systems you can use Kerl to build Erlang versions: https://github.com/yrashk/kerl

Install it into "/erlang". We cannot use "/.erlang" because thats seems to cause an error in the Window's version of Erlang.

Add this to your .zshrc:

# erlang (windows installation)
if [ -d "${HOME}/erlang" ] ; then
    export PATH="$HOME/erlang/bin:$PATH"
fi

Try: $ erl.

Building Elixir

Building Elixir on Cygwin also seems possible but tedious.

Get the precompiled binaries: https://github.com/elixir-lang/elixir/releases/

On Unixy systems try using kiev https://github.com/taylor/kiex or exenv https://github.com/mururu/exenv.

Extract the archive into "~/.elixir".

# elixir (precompiled)
if [ -d "${HOME}/.elixir" ] ; then
    export PATH="$HOME/.elixir/bin:$PATH"
    # we have to use the windows versions
    alias elixir='elixir.bat'
    alias elixirc='elixirc.bat'
    alias iex='iex.bat'
    alias mix='mix.bat'
fi

Please note that these aliases will not be expanded in exs script hashbangs. You can either force the shell to expand the aliases, or you can force symlink the Elixir binaries to the .bat equivalents. The Elixir binaries don't work inside Cygwin.

For now to use iex: iex --werl. --werl is required on Windows.
