How to: Use SourceTree, with git hook via lefthook, running bundle exec with asdf managing Ruby versions

That's a long title huh?

Anyway I got a combination of software I use with an issue that I cannot find the answer on the Internet.

Background

At the time of writing, I use

• SourceTree 3.2.1
• Git (latest, version doesn't matter)
• lefthook 0.7.7 (as git hook manager)
• asdf with ruby plugin

Lefthook Setup

I have hook scripts inside folder ./.githooks under project root (all version controlled)

git config core.hooksPath .githooks
brew install lefthook

Workaround for source tree for path issue

sudo launchctl config user path `echo $PATH`

Issue

I have recently switched from RVM to asdf.
After a restart of my computer I realize that one of my git hooks running bundle exec rubocop no longer works.
The workaround above works for RVM.

Investigation

• lefthook binary is found (with workaround above)
• bundle is using the binary from MacOS built-in Ruby

Solution

In my hook script pre-commit
Add the following before the code running lefthook

# ASDF compatibility
if test -f /usr/local/opt/asdf/libexec/asdf.sh ; then
  . /usr/local/opt/asdf/libexec/asdf.sh
fi
if test -f /opt/homebrew/opt/asdf/libexec/asdf.sh ; then
  . /opt/homebrew/opt/asdf/libexec/asdf.sh
fi
