We currently implement globs by converting them to regexes, and in doing
so, sometimes use grouping. In all but one case, we used non-capturing
groups. But for alternations, we used capturing groups, which was likely
just an oversight. We don't make use of capture groups at all, and while
they usually don't have any overhead, they lead to weird cases like this
one: https://github.com/rust-lang/regex/issues/1059
That particular issue is also a bug in the regex crate itself, which is
fixed in https://github.com/rust-lang/regex/pull/1062. Note though that
the bug fix in the regex crate is required. Even with this patch to
globset, memory usage is reduced (by about half in rust-lang/regex#1059)
but is not returned to where it was prior to the regex 1.9 release.
It turns out our fast path for -w/--word-regexp wasn't quite correct in
some cases. Namely, we use `(?m:^|\W)(<original-regex>)(?m:\W|$)` as the
implementation of -w/--word-regexp since `\b(<original-regex>)\b` has
some unintuitive results in certain cases, specifically when
<original-regex> matches non-word characters at match boundaries.
The problem is that using this formulation means that you need to
extract the capture group around <original-regex> to find the "real"
match, since the surrounding (^|\W) and (\W|$) aren't part of the match.
This is fine, but the capture group engine is usually slow, so we have a
fast path where we try to deduce the correct match boundary after an
initial match (before running capture groups). The problem is that doing
this is rather tricky because it's hard to know, in general, whether the
`^` or the `\W` matched.
This still doesn't seem quite right overall, but we at least fix one
more case.

This PR adds `*.bat` and `*.cmd` file types.
In doing so, it makes a distinction between batch files (old standard
from the MS-DOS era) and command scripts (new flavor - can operate on
batch files, although `*.cmd` is preferred for various reasons, the
main one being batch files will set `ERRORLEVEL` following inconsistent
MS-DOS style rules[1]).

This does not seem to have worked at all. For example, there were
Actions being used that were clearly deprecated/archived[1]. But
Dependabot didn't make a peep. So just get rid of it to avoid the false
sense that someone is checking our dependencies for us.

Previously, sorting worked by sorting the parents and then sorting the
children within each parent. This was done during traversal, but it only
works when sorting parents preserves the overall order. This generally
only works for '--sort path' in ascending order.
This commit fixes the rest of the sorting behavior by collecting all of
the paths to search and then sorting them before searching. We only
collect all of the paths when sorting was requested.
Fixes#2243, Closes#2361
This causes ripgrep to stop searching an individual file after it has
found a non-matching line. But this only occurs after it has found a
matching line.

Adds a new eprintln_locked macro which locks STDOUT before logging
to STDERR. This patch also replaces instances of eprintln with
eprintln_locked to avoid interleaving lines.

Previously, we were only doing a binary existence check on Windows. And
in fact, the main point there wasn't binary existence, but ensuring we
didn't accidentally resolve a binary name relative to the CWD, which
could result in executing a program one didn't mean to run.
However, it is useful to be able to check whether a binary exists on any
platform when associating a glob with a binary. If the binary doesn't
exist, then the association can fail eagerly and let some other glob
apply.
Closes#1946
We also make py/python, md/markdown and ts/typescript aliases of one
another.
Note that this only introduces aliases at the point where default types
are defined. This just makes them a bit easier to read/write, and also
makes it easier to expose more names that describe the same thing.

*.adb and *.ads are the usual extensions for Ada source code,
and *.gpr indicates a GPRbuild project file used for Ada, and
these days often being combined with alire for package dependency
resolution. Alire stores a bunch of files named alire.toml in
different directories in your (gitignored) cache/dependencies/...
Closes#2013
See the README and comments in the build.rs. Basically, this embeds an
XML file that I guess is a way of setting configuration knobs on
Windows. One of those knobs is enabling long path support. You still
need to enable it in your registry (lol), but this will handle the other
half of it.
Fixes#364, Closes#2049
When the extra-verbose style is set for the types tag, completed types
are displayed along with the patterns they correspond to. This can be
enabled by e.g. adding the following to .zshrc:
zstyle ':completion:*:rg:*:types' extra-verbose true
This change also makes _rg_types use the actual rg specified on the
command line to look up types, and it fixes a mangled complete-all
style check
Fixes#2195
I definitely wonder whether I should just drop 'sudo' from the install
instructions and just rely on the user to "know" to do it. But some
commands legitimately do not require 'sudo', so there are actual
differences. Overall, this feels clearer to me but reasonable people can
disagree.
Eclasses are "ebuild libraries" and generally if you're filtering
for/filtering out an ebuild/eclass, you don't want the other either.

This matches the behavior of GNU grep which does not ignore
before-context and after-context completely if the context flag is also
provided.
Note that this change wasn't done just to match GNU grep. In this case,
GNU grep has the more sensible behavior.
