How do you use (un)folding?

[googleson78]

For this single file, with an implicit cradle

x = 3

y = x

These code actions on x

  refactor.extract: Fold x in current file
  refactor.extract: Fold x
  refactor.inline: Unfold x in current file
  refactor.inline: Unfold x

appear to not do anything.

Am I supposed to also install a retrie binary or something similar? I'm using LanguageClient-neovim.

No need for a retrie binary, if the file typechecks it should rewrite to y=3. There may be a bug where the rewrite uses the file on disk, so you may need to save it first.

It is saved. Does this log help?

It seems to be some path related issue?

Yes, that helps.
I have pushed a potential fix to #408
Please test and let me know

Still doesn't work

I've pushed another fix, give it another go when you can.

[googleson78]

Do you mean from master? Trying from current master (e390da5) gives the same error in the log.

#424

Thanks, works from that branch!
