"Root" glob relativity to PWD

[harwood-qualia]

^{(I did a search for "glob" and looked over those questions, but I didn't see one talking about this.)}

This question concerns a glob with a leading / which should only match, in the case of a .gitignore file, a thing in the same directory the .gitignore is in. (Mentioned in the first example: https://git-scm.com/docs/gitignore#_examples)

My understanding is that the pattern !/bar/ means: ignore any "local root" directory bar/ and anything under it. That is how it works for Git, anyway.

I have this setup:

/tmp/example                                                                                                                                                                                                                   
$ tree
.
└── foo
    ├── bar
    │   └── file
    ├── file
    └── qux
        └── bar
            └── file

Here are a few cases:

1. PWD is /tmp/example. No PATH provided.
   👍 Expected behavior.

   /tmp/example                                                                                                                                                                                                                   
   $ rg --files-with-matches --glob '!/bar/' syzygy
   foo/bar/file
   foo/file
   foo/qux/bar/file
   

2. PWD is /tmp/example/foo. No PATH provided.
   👍 Expected behavior, given that the current directory contains that foo/ directory.

   /tmp/example/foo                                                                                                                                                                                                               
   $ rg --files-with-matches --glob '!/bar/' syzygy
   file
   qux/bar/file
   

3. PWD is /tmp/example. PATH is provided as foo/.
   🤔 Hmm... does this make sense?

   /tmp/example                                                                                                                                                                                                                   
   $ rg --files-with-matches --glob '!/bar/' syzygy foo/
   foo/bar/file
   foo/file
   foo/qux/bar/file
   

So, perhaps you'll say, "Yes, 'root' globs are always evaluated relative to the PWD rather than considering any path or paths provided as individual 'roots' for those globs." If so, then it's confirmed. I just need to manage the PWD as well as any provided paths if I want to use 'root' globs. Maybe there's more to it though?

Thanks!

Yeah I think the sensible behavior here is that / is always interpreted relative to the working directory of ripgrep. I think changing it depending on the directory being searched leads to more complicated semantics.
