attempting to use fsmonotir in a coffeescript cake deployment ... I keep hitting the error I mentioned in the subject line, any ideas?

this is the code:
fsmonitor.watch '/', ['*.js'], (change) ->

Hey!

It expects an instance of RelPathList from pathspec.js. I planned to turn an array of strings into one automatically, but I could have forgotten. Until I can fix it, pls either workaround by doing it yourself (see https://github.com/andreyvit/pathspec.js/), or, better yet, cook up a fix and send me a pull request. (You can find a usage example in the cli tool, see bin/fsmonitor.js.)

Ah ok - is it expecting an instance as root too?

&.. thanks for the lightning fast response :)

Nope, root is a string.

Sorry - additional issues:

It does seem to work for a couple of minutes - I don't get any file change notifications - then it just errors out.

I've updated permissions - passed it an instance of RelPathList as such:

list = RelPathList.parse(['/*.coffee', '!/node_modules']);

I never saw ENOSPC, but then, I only tried this on Mac and Windows. If you happen to be on Linux, maybe that's the error you get when you run out of file descriptors? Try increasing ulimit -n if that's correct; fsmonitor uses a file descriptor per each monitored folder, so if you have a ton of folder and a low default ulimit, that could be it.

Otherwise, I don't really know the reason.
