Slashes don't work inside logic operators

[ntrrgc]

For instance, querying the following

glob.sync("!(a/b)", {})

will throw this error:

node_modules/glob/sync.js:147
  var dotOk = this.dot || rawGlob.charAt(0) === '.'
                                 ^

TypeError: Cannot read property 'charAt' of undefined

It is correct that slashes do not work inside of extglob patterns such as !(a|b). Those can only be used to indicate path parts, not entire paths. This is how Bash works as well. In that case, the pattern is read as a file named b) inside of a folder named !(a, which is weird, but not impossible.

That being said, you have found a bug here, because it should not throw if you use a pattern like that.

I was trying to implement something like gitignore, with a set of filtered patterns. Isn't there a way to do that with node-glob?

You can take a look at how fstream-ignore does it. That's what npm uses for .npmignore files. https://github.com/npm/fstream-ignore

Thanks for the tip. I couldn't find something like that the last time I
searched.
