I love emacs' tags-query-replace function, which allows me to do a search-and-replace across an entire repo. But to do that I need a TAGS file that, at least, lists all the Hsakell files in GHC.

What is the approved way to construct a TAGS file for a bunch of Haskell modules? Is this documented anywhere?

I haven't tried this recently on GHC but my first instinct would be to use hasktags [1]: $ cabal install hasktags $ hasktags --etags ./compiler At some point in the past I would have said that ideally Hadrian would be able to build such a thing. However, at this point TAGS files are slowly falling out of fashion in favor of language servers. Another way to reach a similar end would be to rather search-and-replace across all git-tracked files. However, somewhat surprisingly, a bit of Googling didn't turn up any easy way of accomplishing this. The closest I can find is [1].
