What version of ripgrep are you using?

-SIMD -AVX (compiled)

How did you install ripgrep?

cargo install

What operating system are you using ripgrep on?

Describe your bug.

Several of our repos have a pattern in their .gitignore file which git grep is fine with, but rg shows an error for.

What are the steps to reproduce the behavior?

git init foo && cd foo
echo "^\.git\/" >.gitignore
rg sometext

What is the actual behavior?

Show the command you ran and the actual output. Include the --debug flag in
your invocation of ripgrep.

If the output is large, put it in a gist: https://gist.github.com/

If the output is small, put it in code fences:

No files were searched, which means ripgrep probably applied a filter you didn't expect.
Running with --debug will show why files are being skipped.

What is the expected behavior?

Ripgrep/globset should not consider this an error as git grep does not.

This is fixed.

It's worth pointing out that escaping a / is superfluous. So while it's technically permissible, it isn't accomplishing anything by being there.

Although I appreciate it's superfluous, I don't manage (or have sufficient input-into/control-of) all the repositories I read from. As it's permissible it's great that it's no longer an error, thank you.

textproc/ripgrep: update to 14.0.2
3d89a00 
14.0.2 (2023-11-27)
===================
This is a patch release with a few small bug fixes.

Bug fixes:

* [BUG #2654](BurntSushi/ripgrep#2654):
  Fix `deb` release sha256 sum file.
* [BUG #2658](BurntSushi/ripgrep#2658):
  Fix partial regression in the behavior of `--null-data --line-regexp`.
* [BUG #2659](BurntSushi/ripgrep#2659):
  Fix Fish shell completions.
* [BUG #2662](BurntSushi/ripgrep#2662):
  Fix typo in documentation for `-i/--ignore-case`.


14.0.1 (2023-11-26)
===================
This a patch release meant to fix `cargo install ripgrep` on Windows.

Bug fixes:

* [BUG #2653](BurntSushi/ripgrep#2653):
  Include `pkg/windows/Manifest.xml` in crate package.


14.0.0 (2023-11-26)
===================
ripgrep 14 is a new major version release of ripgrep that has some new
features, performance improvements and a lot of bug fixes.

The headlining feature in this release is hyperlink support. In this release,
they are an opt-in feature but may change to an opt-out feature in the future.
To enable them, try passing `--hyperlink-format default`. If you use [VS Code],
then try passing `--hyperlink-format vscode`. Please [report your experience
with hyperlinks][report-hyperlinks], positive or negative.

[VS Code]: https://code.visualstudio.com/
[report-hyperlinks]: BurntSushi/ripgrep#2611

Another headlining development in this release is that it contains a rewrite
of its regex engine. You generally shouldn't notice any changes, except for
some searches may get faster. You can read more about the [regex engine rewrite
on my blog][regex-internals]. Please [report your performance improvements or
regressions that you notice][report-perf].

[report-perf]: BurntSushi/ripgrep#2652

Finally, ripgrep switched the library it uses for argument parsing. Users
should not notice a difference in most cases (error messages have changed
somewhat), but flag overrides should generally be more consistent. For example,
things like `--no-ignore --ignore-vcs` work as one would expect (disables all
filtering related to ignore rules except for rules found in version control
systems such as `git`).

**BREAKING CHANGES**:

* `rg -C1 -A2` used to be equivalent to `rg -A2`, but now it is equivalent to
  `rg -B1 -A2`. That is, `-A` and `-B` no longer completely override `-C`.
  Instead, they only partially override `-C`.

Build process changes:

* ripgrep's shell completions and man page are now created by running ripgrep
with a new `--generate` flag. For example, `rg --generate man` will write a
man page in `roff` format on stdout. The release archives have not changed.
* The optional build dependency on `asciidoc` or `asciidoctor` has been
dropped. Previously, it was used to produce ripgrep's man page. ripgrep now
owns this process itself by writing `roff` directly.

Performance improvements:

* [PERF #1746](BurntSushi/ripgrep#1746):
  Make some cases with inner literals faster.
* [PERF #1760](BurntSushi/ripgrep#1760):
  Make most searches with `\b` look-arounds (among others) much faster.
* [PERF #2591](BurntSushi/ripgrep#2591):
  Parallel directory traversal now uses work stealing for faster searches.
* [PERF #2642](BurntSushi/ripgrep#2642):
  Parallel directory traversal has some contention reduced.

Feature enhancements:

* Added or improved file type filtering for Ada, DITA, Elixir, Fuchsia, Gentoo,
  Gradle, GraphQL, Markdown, Prolog, Raku, TypeScript, USD, V
* [FEATURE #665](BurntSushi/ripgrep#665):

  The `--debug` flag now indicates whether stdin or `./` is being searched.

  Make `-d` a short flag for `--max-depth`.
* [FEATURE #2645](BurntSushi/ripgrep#2645):
