Q: Is `/mnt/c/` with WSL supported?

[Wizek]

I'm trying to use GHCid with Windows Subsystem for Linux, and I am running into file changes only being picked up when I set --poll. Is hfsnotify supposed to work on mounted drives on WSL like /mnt/c? Or is this known to being not yet supported?

Here is the relevant GHCid issue: ndmitchell/ghcid#121

also got this issue, i notice hinotify (the package fsnotify uses) works fine on /mnt/c/ paths

[dten]

it seems that CloseWrite is never fired (when editing from windows) on wsl from hinotify and so no modified events are sent

Thanks for the research @dten! Given that fswatch doesn't support WSL, I think this will be a wontfix for fsnotify as well, for now at least. We should revisit this if/when the WSL inotify system has its bugs ironed out.

I'm on Windows 10 17751, and confirm that ghcid works for /mnt/c/ paths out of the box. fsnotify version is 0.3.0.1.

This is exciting! Thanks for reporting
