Polling instead of inotify

[trevex]

I am currently using reflex to recompile go application when something changes. Unfortunately I noticed reflex is not working properly when inside a VM with filesystems like vboxsf. Is there any chance that reflex will support somethink like force-polling or polling as a fallback?

I'm having the same issue on my Vagrant environment. I've found an issue opened for fsnotify fsnotify/fsnotify#9.
https://github.com/radovskyb/watcher this is a GO package for watching for files or directory changes without using inotify.

If we implemented polling, how would we detect that the normal notification method or the platform doesn't work and that we should poll instead?

I can confirm the same issue when using Docker for Windows.

I think it should be by ways of configuration instead of automatic detection. Similar to https://webpack.js.org/configuration/dev-server/#devserverwatchoptions-
So perhaps another command line option:

-p, --poll=1000
    Turn on polling to watch for file changes. Default uses file system notification.

This issue has pained me for a long time. I tried the polling method but it gets slow when the project is big. I finally decided to write my own tool to overcome this problem. It has a similar design to reflex. Hope this will help you guys: https://github.com/AgentCosmic/xnotify
