Allow excluding file patterns by passing in a file about fswatch HOT 9 CLOSED

In the meantime, git-check-ignore allows deferring this logic togit itself: fswatch . | while read file; do git check-ignore -q $file || echo $file; done

Hi @bengillies,

In fact, this is an issue which has already been requested. I leave it open for reference and hope I'll be able to integrate it quite soon. The only catch I have (that I have not investigated yet) is a convenient way to implement the ** wildcard in patterns, since AFAIK functions like glob or fnmatch do not recognize it.

If someone has got an idea about this, let's brainstorm, since end of the year is quite a busy time.

Thanks for replying so quickly. I'm afraid I'm not much of a C++ person so probably not much help.

Question though: does it really need to support ** immediately?

from fswatch.

You're welcome.

Well, it certainly needs not, although I'd like to avoid confusing the users. git had the same problems some time ago: ** was initially implemented only on certain systems, leading users to quite a good deal of confusion.

I want to have a look at git sources to check what they've done and then decide what I'll do. I'm just short of time.

I'll then consider omitting implementing ** and see how it goes.

Cheers,

Hi @ricardobeat, I'm afraid this issue hasn't been worked on yet.

Being able to exclude files is important so that fswatch can exert a lesser load on the system, especially when the monitor uses limited resources such as file descriptors. Trimming an otherwise huge file hierarchy is a feature that is definitely required. Maintaining the current implementation (a fswatch-specific syntax) is OK to me.

Having fswatch understand other exclude file types may be nice, but it's not only essential: the output can be filtered, how a user exactly wants. Furthermore, as @ricardobeat pointed out, in the case of git it's very easy to check a path against the ignore patterns.

I'm closing this issue and I'll probably add an example using git check-ignore to the documentation.
