Why would you want to use Elixir master?
There are really cool upcoming features in next Elixir release. This
sentence is true no matter which one is the upcoming release, in my
experience ;). It would be awesome to - on occasion - try some of these
out. The upcoming
v1.6 release has an Elixir code formatter built in,
and you will need it if you want to cut the code formatting discussion
Being able to easily check out, update and switch between versions might also help you contributing to Elixir itself. The source is on your computer - open it and read it :D.
It’s pretty easy to compile Elixir from source. You will need the usual
packages for Erlang,
build-essentials, development versions of
make and - optionally
wxgtk3 library if you
want to use graphical tools that come with Erlang - such as the
On Ubuntu, install those with something like:
sudo apt-get install git build-essential libssl-dev libreadline-dev libncurses5-dev zlib1g-dev m4 curl wx-common libwxgtk3.0-dev autoconf
the package versions might differ between Ubuntu releases, but overall that’s all you need.
Check out the most recent
master from Github:
$ git clone https://github.com/elixir-lang/elixir.git
and build it:
$ cd elixir $ make
At this point, you will have the usual command-line tools that come with
mix) built and installed in
To use this locally built version of Elixir, all you need to do is to
set up the
$PATH variable to point to your
bin/ directory where
those executables were put.
Using asdf version manager
Manual approach is fine, but you might be already using a version manager to manage different Elixir versions. If you chose asdf version manager, you are lucky - it supports installing Elixir form master with one simple command:
$ asdf install elixir ref:master
If you do not have
asdf version manager installed, I highly recommend
you do. It’s got pretty shitty name, but is an awesomely reliable tool,
which I do use to manage my Ruby, Elixir, Node.js and Erlang versions.
You will need
asdf-elixir plugins, and
you will need to install Erlang before you install Elixir.
If the build succeeds, a
ref:master should be listed among installed
$ asdf list elixir 1.3.4 1.4.0 1.4.1 1.4.2 1.4.5 1.5.1 ref:master
Use it globally with
asdf global elixir ref:master or within the scope
of project with:
asdf local elixir ref:master.
asdf installs the Elixir in
the “-“ replaces “:” in directory name. You can easily update this
installation to newer version of Elixir with:
$ cd ~/.asdf/installs/elixir/ref-master $ git checkout master $ git pull $ make clean && make
After that, and
elixir -v should show you new development version,
with version number pointing to the latest commit on
asdf simply expects the Elixir repository with built executables
to be present in it’s
~/.asdf/installs/elixir directory, you can also
check out Elixir source from Github to other directory on your system,
~/Projects/elixir and symlink it there:
$ cd Projects $ git clone https://github.com/elixir-lang/elixir.git $ cd elixir $ make $ ln -s `pwd` ~/.asdf/installs/elixir/ref-master
ref-master version of Elixir should be listed as
one of installed, available versions:
$ asdf list elixir 1.3.4 1.5.1 ref:master
That’s all folks!
