asdf Build Status

extendable version manager

Supported languages include Ruby, Node.js, Elixir and more. Supporting a new language is as simple as this plugin API.

SETUP

Copy-paste the following into command line:

git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.4.0

Depending on your OS and shell, run the following:

  • Bash on Ubuntu (and other Linux distros):

    echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc

  • Bash on macOS:

    echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bash_profile
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bash_profile

  • Zsh:

    echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.zshrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.zshrc

  • Fish:

    echo 'source ~/.asdf/asdf.fish' >> ~/.config/fish/config.fish
mkdir -p ~/.config/fish/completions; and cp ~/.asdf/completions/asdf.fish ~/.config/fish/completions

For most plugins, it is good if you have installed the following packages OR their equivalent on your OS

  • macOS: Install these via homebrew coreutils automake autoconf openssl libyaml readline libxslt libtool unixodbc
  • Ubuntu: automake autoconf libreadline-dev libncurses-dev libssl-dev libyaml-dev libxslt-dev libffi-dev libtool unixodbc-dev
  • Fedora: automake autoconf readline-devel ncurses-devel openssl-devel libyaml-devel libxslt-devel libffi-devel libtool unixODBC-devel

That's all ~! You are ready to use asdf

USAGE

Manage plugins

Plugins are how asdf understands how to handle different packages.

You can find a list of all asdf plugins in the plugins repository.

There is a super-simple API for supporting more languages.

Add a plugin
asdf plugin-add <name>
# asdf plugin-add erlang

If the plugin you want to install is not part of the plugins repository, you can add it using its repository URL:

asdf plugin-add <name> <git-url>
# asdf plugin-add elm https://github.com/vic/asdf-elm
List installed plugins
asdf plugin-list
# asdf plugin-list
Remove a plugin
asdf plugin-remove <name>
# asdf plugin-remove erlang
Update plugins
asdf plugin-update --all

If you want to update a specific package, just say so.

asdf plugin-update <name>
# asdf plugin-update erlang

Manage versions

asdf install <name> <version>
# asdf install erlang 17.3

asdf current <name>
# asdf current erlang
# 17.3 (set by /Users/kim/.tool-versions)

asdf uninstall <name> <version>
# asdf uninstall erlang 17.3

If a plugin supports downloading & compiling from source, you can also do this ref:foo (replace foo with the branch/tag/commit). You'll have to use the same name when uninstalling too.

Lists installed versions
asdf list <name>
# asdf list erlang
List all available versions
asdf list-all <name>
# asdf list-all erlang

View current version

asdf current <name>
# asdf current erlang
# 17.3 (set by /Users/kim/.tool-versions)

Set current version

asdf global <name> <version>
asdf local <name> <version>
# asdf global elixir 1.2.4

global writes the version to $HOME/.tool-versions.

local writes the version to $PWD/.tool-versions, creating it if needed.

Alternatively, if you want to set a version only for the current shell session or for executing just a command under a particular tool version, you can set an environment variable like ASDF_${TOOL}_VERSION.

The following example runs tests on an Elixir project with version 1.4.0. The version format is the same supported by the .tool-versions file.

ASDF_ELIXIR_VERSION=1.4.0 mix test

The .tool-versions file

Add a .tool-versions file to your project dir and versions of those tools will be used. Global defaults can be set in the file $HOME/.tool-versions

This is what a .tool-versions file looks like:

ruby 2.2.0
nodejs 0.12.3

The versions can be in the following format:

  • 0.12.3 - an actual version. Plugins that support downloading binaries, will download binaries.
  • ref:v1.0.2-a or ref:39cb398vb39 - tag/commit/branch to download from github and compile
  • path:/src/elixir - a path to custom compiled version of a tool to use. For use by language developers and such.
  • system - this keyword causes asdf to passthrough to the version of the tool on the system that is not managed by asdf.

To install all the tools defined in a .tool-versions file run the asdf install command with no other arguments in the directory containing the .tool-versions file.

You can view/modify the file by hand or use asdf local and asdf global to manage it.

The $HOME/.asdfrc config file

Add a .asdfrc file to your home directory and asdf will use the settings specified in the file. The file should be formatted like this:

legacy_version_file = yes

Settings

  • legacy_version_file - defaults to no. If set to yes it will cause plugins that support this feature to read the version files used by other version managers (e.g. .ruby-version in the case of Ruby's rbenv).

Uninstall

Uninstalling asdf is easy.

Docker images

The asdf-alpine and asdf-ubuntu projects are an ongoing effort to provide Dockerized images of some asdf tools. You can use these docker images as base for your development servers, or for running your production apps.

Development

To develop the project, you can simply git clone the master branch. If you want to try out your changes without making change to your installed asdf, you can set the $ASDF_DIR variable to the path where you cloned the repository, and temporarily prepend the bin and shims directory of the directory to your path.

We use bats for testing, so make sure bats test/ passes after you made your changes.
