Instead of re-parsing each FilePath here, we reuse the globs parsed above in checkGlob.

And instead of re-parsing and then re-running the glob find, we just use the results generated above.

these args are all just String 🤪 and were incorrectly documented before.

liftCM was not previously exported, but it is necessary to actually use this if the liftint interface doesn't suffice - and since that interface has a forced return of (), it can't work here.

If we don't want to expose this I can probably replace with a function like liftInt but that allows a secondary return, like,
liftIntWith

can simplify this to globMatches t and rely on callers to concat the args, too 🤷🏻

BTW the API change label is neither a complaint nor a barrier to getting it into 3.14; it does mean backporting to 3.12 isn't possible. |
This PR modifies the glob logic to avoid doing redundant work. Results of operations are now passed forward into further checks.
Locally, this improves the time for a no-op
cabal replfrom 50s to 32s.Combined with my other PRs on this, I think this whole operation on our large
extra-source-fileswill go from 35s to 65ms 😄Template Α: This PR modifies behaviour or interface
