Generic plugin for versioning system tools with asdf.
This is a plugin for tools that have No ASDF installer (maybe because the package
is hosted at a private location, or perhaps things that you already installed with
a vendor package manager, eg
brew on OSX which supports many installed versions).
Or maybe things that can only be installed with some GUI interaction and for which creating an asdf installer would be a bit complicated, eg Android tools, AWS or Google Cloud tools.
For example, many systems already come with
perl installed (two versions on my system).
Or on OSX where you can install the java tools via many methods, like the official package
from java.com, or by using other methods like
or sdk managers like sdkman or jabba,
there are lots of ways to get things installed on your system, and ASDF wont ever replace
In these cases you might still want to use the convenient ASDF
.tool-versions file to
enable the right tool per project or system wide, so that you just cd into the
working directory of your like and let asdf select the right executable for you.
The first thing you have to do is to think of a good name. That is the name of the
tool you will be selecting versions for. Say
## READ above before copy-paste this line # You can execute this as many times as you want with different names $ asdf plugin-add NAME https://github.com/vic/asdf-link.git
This can be anything, from now on, these examples will be for
$ asdf plugin-add jdk https://github.com/vic/asdf-link.git
Now if you execute
asdf list-all jdk you will notice it will only say
That is because we cannot possibly know which versions are available. And actually,
this plugin will let you install ANY version you give to it. So it's up to you
to use a meaningful version.
In my case, I have the following jdks
1.8 which I downloaded from the java
1.9 which was installed with
brew install Caskroom/versions/java9-beta
$ ls /Library/Java/JavaVirtualMachines/ jdk1.8.0_111.jdk jdk-9.jdk
To use them, lets tell ASDF about their existance with:
$ asdf install jdk 1.9 Link your system binaries to /Users/vic/.asdf/installs/jdk/1.9/bin
As previously mentioned, this plugin lets you install any version,
actually it just creates a
bin/ directory for you. The idea is that
we link (hence the plugin name) our versioned binaries into that
bin/ directory directory.
# linking all the java tools into the 1.9 versioned bin/ $ ln -vs /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/bin/* /Users/vic/.asdf/installs/jdk/1.9/bin/ # after this, just reshim $ asdf reshim jdk
And we are done, you can create a
.tool-versions in the current directory
asdf local jdk 1.9. See the asdf
documentaion for more on managing versions.
The advantage of using this plugin is that even if you have lots of binaries on
by hand-picking and linking them inside the plugin's
bin/ directory, you get shims for free. The
following is the travis test we use, linking perl.
# perla is spanish for perl $ asdf plugin-add perla https://github.com/vic/asdf-link.git $ asdf install perla 5.18 $ ln -s /usr/bin/perl5.18 ~/.asdf/installs/perla/5.18/bin/perla $ asdf reshim $ asdf local perla 5.18 $ perla -v
