asdf-elixir
Elixir plugin for asdf version manager
Install
This plugin needs unzip to be installed.
If you have a Debian system you can install it by typing:
sudo apt-get install unzip
Elixir requires Erlang to be installed. You can use the asdf-erlang plugin to install Erlang versions.
asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git
Check compatibility between elixir and erlang:
Elixir precompiled versions
Precompiled Elixir packages are built by Bob whenever a git push or a new release is made at the elixir repo. There's also a status page available with an overview of all available packages and their availability.
The precompiled packages are built against every officially supported OTP version, however if you only specify the
elixir version, like 1.4.5, the downloaded binaries will be those compiled against the oldest OTP release
supported by that version.
If you would like to use precompiled binaries built with a more recent OTP, you can append -otp-${OTP_MAJOR_VERSION} to any installable version that can be given to asdf-elixir.
So, for example, to install Elixir 1.5.0 and take advantage of the new features from OTP-20 you might install version 1.5.0-otp-20.
Be sure to also install the corresponding Erlang/OTP version with asdf-erlang, and to have both selected versions in your
.tool-versions file.
Note: You do not need to have Erlang installed to install a precompiled version of Elixir installed, but you will need to have it available at runtime, otherwise your Elixir commands will fail. Even though it's possible to install Elixir first, it's recommended to install Erlang first.
Compiling from a Git reference or from source
Using the CLI
You can download and compile a specific commit reference from the Elixir GitHub repository by running: asdf install elixir ref:<commit reference>. You can then set the local/global version to your new version by running:
asdf local elixir ref:<commit reference>
# Or
asdf global elixir ref:<commit reference>
You can also compile Elixir from source without using asdf (for example, so that you can use the master branch of elixir or a branch with your own modifications), then use it by specifying the directory path:
# After Elixir already installed into /path/to/elixir
asdf local elixir path:/path/to/elixir
# Or
asdf global elixir path:/path/to/elixir
.tool-versions file
You can specify the version to install with a line like so in your .tool-versions file:
elixir ref:<commit reference>
Or if you've already compiled Elixir from source in a specific directory:
elixir path:/path/to/elixir
Note that the path specified must be an absolute path to the Elixir installation's root directory (e.g. the directory containing the bin directory).
Elixir escripts support
This plugin supports elixir escripts, adding them to your path just like any other elixir binary.
Whenever you install a new escript with mix escript.install you need to asdf reshim elixir in order
to create shims for it.
Default mix commands
After installing you can specify which additional mix commands must be run after adding a new Elixir version.
This can be particurlarly useful for installing often used archives.
They need to be specified in $HOME/.default-mix-commands, the flag --force will be added by default.
An example:
local.hex
local.rebar
archive.install hex phx_new
