Always "No files matched your search criteria.."

[simonmichael]

Thanks for calligraphy!

I tried every variant of the MODULE argument and working directory I could think of, but I couldn't figure out how to make it find files. Eg in this repo:

~/src/calligraphy$ calligraphy Calligraphy
No files matched your search criteria..

Did you generate HIE files? If I run this in this repo, it correctly produces the call graph for the Calligraphy module: cabal run --ghc-options=-fwrite-ide-info calligraphy -- Calligraphy --stdout-dot

[simonmichael]

(I had forgotten to generate them after switching to the calligraphy repo to test there, but doing so didn't help.)

I have been using stack. Switching to cabal, I can reproduce success with your command cabal run --ghc-options=-fwrite-ide-info calligraphy -- Calligraphy --stdout-dot. But that's the only command I've found that works, so I still have questions:

~/src/calligraphy$ cabal run --ghc-options=-fwrite-ide-info calligraphy -- Calligraphy --stdout-dot  # works
~/src/calligraphy$ calligraphy -- Calligraphy --stdout-dot
Warning: no output options specified, run with --help to see options

• The hie files are in place, but the cabal run part is still needed somehow ?
• Isn't --stdout-dot an output option ?
• The help implies that just calligraphy with no arguments should do something using defaults

Ah, I should have removed the -- when I ran calligraphy by itself, then it works normally (my bad). And I think the original failure is because it finds .hie files generated by a cabal build, but not the ones generated by a stack build.

(sample hie file locations:) cabal: dist-newstyle/build/aarch64-osx/ghc-9.8.2/calligraphy-0.1.6/build/extra-compilation-artifacts/hie/* stack: .stack-work/dist/aarch64-osx/ghc-9.8.2/build/*

Very strange. For context, this is what happens for me:

Ah, I hadn't seen your new messages. I'm not very familiar with stack, maybe there's an easy way to pick up stack build artifacts too

[simonmichael]

Thanks for your help. Another small improvement might be to have the error say "no .hie files were found, have you built with CMD" - I thought it was failing to find my source files and wasted time on that.
