Module documentation for 0.1.7.0

githash

Build Status

Some handy Template Haskell splices for including the current git hash and branch in the code of your project. Useful for including in panic messages, --version output, or diagnostic info for more informative bug reports.

Most of the complication in the GitHash module is due to the various places the current git hash might be stored:

  1. Detached HEAD: the hash is in .git/HEAD
  2. On a branch or tag: the hash is in a file pointed to by .git/HEAD in a location like .git/refs/heads
  3. On a branch or tag but in a repository with packed refs: the hash is in .git/packed-refs

These situations all arise under normal development workflows, but there might be further scenarios that cause problems. Let me know if you run into them!

0.1.7.0

  • Expose giFiles to users.

0.1.6.3

  • Specify protocol.file.allow=always for latest git #28

0.1.6.2

  • Fixed bugs; now this library’s Template Haskell functions are much more likely on recompilation to detect Git update that doesn’t affect workspace: e.g. git switch -c <new_branch> (equivalently git checkout -b <new_branch>) and git commit --amend --only. Implemented in #23.
