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:
- Detached HEAD: the hash is in
.git/HEAD - On a branch or tag: the hash is in a file pointed to by
.git/HEADin a location like.git/refs/heads - 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!
