Find out which paths to watch about node-ignore HOT 4 CLOSED

I don't exactly understand your problem

from node-ignore.

I would like to know, for a given path, if all possible subpaths are ignored, or not.

In other words, is there a matching regex that ignores the path and no unignore regexes that match subpaths?

This knowledge is useful for monitoring a git workdir on Linux for changes. You can't get filesystem events for subtrees so you must recurse, and if a subtree is fully ignored you don't need to recurse into it.

An optional prefix "!" which negates the pattern; any matching file excluded by a previous pattern will become included again. It is not possible to re-include a file if a parent directory of that file is excluded. Git doesn’t list excluded directories for performance reasons, so any patterns on contained files have no effect, no matter where they are defined. Put a backslash ("") in front of the first "!" for patterns that begin with a literal "!", for example, "!important!.txt".

From gitignore spec

And node-ignore is an JavaScript implementation according to the gitignore spec

I suggest to get better understanding about the usage of .gitignore file

from node-ignore.

/*/
!/bar/hello/

Will not work expectedly, coz /bar is already ignored

Change it to

/*
!/bar
/bar/*
!/bar/hello

from node-ignore.
