Data.GitEmbed

Use Template Haskell to embed Git revision, branch, and tag information.

Also adds dependent files so that changes to git refs cause a rebuild.

Example:

{-# LANGUAGE TemplateHaskell #-}
import Data.GitEmbed

main :: IO ()
main = putStrLn ("Git revision: " ++ gitRev ++ ", branch: " ++ gitBranch)

gitRev :: String
gitRev = $(embedGitShortRevision)

gitBranch :: String
gitBranch = $(embedGitBranch)
