watchr New files not automatically watched.

New files are not automatically picked up to be watched. watchr must be stopped & re-started for saved changes in new files to match a watched pattern.

Ubuntu w/ ext3 fs watchr 0.5.7 rev 0.3.1

Not really a big deal. autotest has the same problem.

+1 would also like to be notified if this gets fixed.

Detecting new files is currently not supported. This is mainly due to how rev works in the backend. It's pretty much the #1 feature I want to implement though, so it will be in there soon-(ish). There are various ways to go about it though and I still have to see which one's the most appropriate.

I'll leave this issue open until the feature gets added.

@jhelwig btw, as a temporary workaround there are two options:

touch/save the script file (it will rescan for files matching the patterns)
add a signal handler in your script that touches the script file for you. you can use the #path method for that (system "touch #{path}").

Steven Parkes has a fork of watchr that uses EventMachine to get this functionality instead of rev. Last I spoke with him, I got the impression that it was functional, but there was still some work that he wanted to do.

Thanks. Yeah I'm aware of his fork, playing with it atm actually. I've tried having an EM backend twice before (one attempt is still in a branch http://github.com/mynyml/watchr/blob/em/lib/watchr/event_handlers/unix.rb) so i'm pretty interested in his approach.

One other solution I was considering is using inotify and kqueue directly (the earliest version of watchr used inotify directly http://github.com/mynyml/watchr/blob/f0a0b3045f4458cb973eb708cce3d4b3905ce2fe/lib/watchr/event_handlers/linux.rb) instead of the rev wrapper, since it allows more flexibility, including watching directories. That power would come with potential maintenance headaches though, so at this point smparkes's solution seems to be the most interesting one.

Touching or reloading the script isn't really an option for me since that throws away the state I've been collecting up to that point. Would be nice to have this solved in rev.

Any news on this front?

+1 for this as well.

I'm currently using a custom ruby project to run all my tests, linting, and compilation. I would love to abandon it in favour of watchr, but I can't without the ability to detect new files.
