replacement for inotify and its successor hgwatchman

[Uwe Brauer]

Hi

Reading (the bit outdated?)
https://gregoryszorc.com/blog/2013/05/12/thoughts-on-mercurial-(and-git)/

I came across inotify (that  is no disabled)
and its successor hgwatchman, whose link to bitbucket is no
de functional. I might find it using the archive, but

What do others recommend? Is there a similar functionality in core
mercurial or any other extension 

Regards
