asdf

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 v0.2.0

Depending on your OS, run the following

# For Ubuntu or other linux distros
echo '. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo '. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc

# OR for Mac OSX
echo '. $HOME/.asdf/asdf.sh' >> ~/.bash_profile
echo '. $HOME/.asdf/completions/asdf.bash' >> ~/.bash_profile

If you use zsh or any other shell, replace .bashrc with the config file for the respective shell.

For fish, you can use the following:

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

• OS X: Install these via homebrew 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. Below is a list of plugins for languages. There is a super-simple API for supporting more languages.

Language	Repository	CI Status
Elixir	asdf-vm/asdf-elixir
Elm	vic/asdf-elm
Erlang	asdf-vm/asdf-erlang
Go	kennyp/asdf-golang
Idris	vic/asdf-idris
Julia	rkyleg/asdf-julia
LFE	vic/asdf-lfe
Lua	Stratus3D/asdf-lua
LuaJIT	smashedtoatoms/asdf-luaJIT
LuaJIT-luarocks	smashedtoatoms/asdf-luaJIT-luarocks
OpenResty	smashedtoatoms/asdf-openresty
MongoDB	sylph01/asdf-mongodb
Node.js	asdf-vm/asdf-nodejs
PHP	odarriba/asdf-php
Postgres	smashedtoatoms/asdf-postgres
Python	tuvistavie/asdf-python
Redis	smashedtoatoms/asdf-redis
Riak	smashedtoatoms/asdf-riak
Ruby	asdf-vm/asdf-ruby
Rust	code-lever/asdf-rust
Terraform	neerfri/asdf-terraform

Add a plugin

asdf plugin-add <name> <git-url>
# asdf plugin-add erlang https://github.com/asdf-vm/asdf-erlang.git

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.

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.

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).
