Use a git hook to match a Jira issue ID from the current branch, and prepend it to every commit message
Assuming the current branch contains a Jira issue ID, you can use a git hook script to prepend it to every commit message.
Create an empty commit-msg git hook file, and make it executable. From your project's root directory:
install -b -m 755 /dev/null .git/hooks/commit-msg
Save the following script to the newly-created .git/hooks/commit-msg file:
Tageless Final interpreters are an alternative to the traditional Algebraic Data Type (and generalized ADT) based implementation of the interpreter pattern. This document presents the Tageless Final approach with Scala, and shows how Dotty with it's recently added implicits functions makes the approach even more appealing. All examples are direct translations of their Haskell version presented in the Typed Tagless Final Interpreters: Lecture Notes (section 2).
The interpreter pattern has recently received a lot of attention in the Scala community. A lot of efforts have been invested in trying to address the biggest shortcomings of ADT/GADT based solutions: extensibility. One can first look at cats' Inject typeclass for a naive implementation of [Data Type à la Carte](http://www.cs.ru.nl/~W.Swierstra/Publica
