How to run haskell-hie from cli #204
Description
Just trying out the haskell-hie indexer. I feel like something like this should work but no luck:
# in the tests dir
$ pwd
/home/dons/Glean/glean/lang/haskell/tests/code
# make some .hie files
$ ghc --make -fwrite-ide-info B.hs
Loaded package environment from /home/dons/.ghc/x86_64-linux-8.10.7/environments/default
[1 of 2] Compiling A ( A.hs, A.o )
[2 of 2] Compiling B ( B.hs, B.o )
$ ls
A.hi A.hie A.hs A.o B.hi B.hie B.hs B.o
$ cd
$ cd Glean/
$ glean-shell
