I use `hasktags -b .` in the compiler directory, and it generates a `tags` file with lines in it like

```
tags\021080:mkHsPar ./GHC/Hs/Utils.hs 142
tags\021081:mkHsParPV ./parser/RdrHsSyn.hs 1920
tags\021082:mkHsParPV ./parser/RdrHsSyn.hs 2019
tags\021083:mkHsParPV ./parser/RdrHsSyn.hs 2072
tags\021084:mkHsParPV ./parser/RdrHsSyn.hs 2154
```

This gives the full path, and emacs is happy.
And of course in this example mkHsParPV does in fact have multiple definitions, it is a class method.

Hello devs,

I also often jump to files. In my case usually using VS Code using Ctr+P as well which searches for files by name.
While I can check which folder a file is in in the case of duplicates it is a overhead which this refactor forces onto me.

While there are workarounds, both for my case as for Matts. It's worth asking if requiring these workarounds is better
than just accepting redundant prefixes on module names.

Personally I would prefer unique file names even at the cost of redundancy.
I rarely add import statements/full module names, but I *very* often jump to files.

Cheers
Andreas

Duplicate record fields is going to make this a bigger problem. Vim does support duplicate tags (:tselect and :tjump and related bindings), but hopefully haskell-ide-engine will one day provide us with semantic tags and solve this problem once and for all!

.

I just configured my editor to use fzf and now I can use the `:GFiles`
command to perform fuzzy search on files which is probably better than
tags. If anyone else is using NixOS, all I had to do was add the
`fzf-vim` plugin to the vim configuration.

Cheers,

Matt
