It turns out that if there are text anchors (that is, \A or \z, or ^/$
when multi-line is disabled), then the "fast" line searching path isn't
quite correct. Since searching without multi-line mode is exceptionally
rare, we just look for the presence of text anchors and specifically
disable the line terminator option in 'grep-regex'. This in turn
inhibits the "fast" line searching path.

When a glob pattern ended with a \/, and since we permit backslash
escapes, the glob parser gave a "dangling escape" error. Which is weird,
because the \ is clearly not dangling.
The issue is that the layer above the glob parser, the gitignore parser,
was stripping the trailing / so that it wouldn't be part of the matching
logic. Of course, stripping the trailing / while it is escaped without
removing the backslash escape is wrong. So we do that here.

This furthers our kludge of dealing with PCRE2's look-around in the
printer. Because of our bad abstraction boundaries, we added a kludge to
deal with PCRE2 look-around by extending the bytes we search by a fixed
amount to hopefully permit any look-around to operate. But because of
that kludge, we wind up over extending ourselves in some cases and
dragging along those extra bytes.
We had fixed this for simple searching by simply rejecting any matches
past the end point. But we didn't do the same for replacements. So this
commit extends our kludge to replacements.
Thanks to @sonohgong for diagnosing the problem and proposing a fix. I
mostly went with their solution, but adding the new replacement routine
as an internal helper rather than a new APIn in the 'grep-matcher'
crate.

Like .hpp, .hh is an occasionally used extension for C++ headers
(to distinguish them from C headers). At least one popular project,
FreeBSD, uses this extension.

PR #2192
This improves the error message printed when ripgrep can't read the
file path pointed to by RIPGREP_CONFIG_PATH. Specifically, before this
change:
$ RIPGREP_CONFIG_PATH=no_exist_path rg 'search regex'
no_exist_path: No such file or directory (os error 2)
And now after this change:
$ RIPGREP_CONFIG_PATH=no_exist_path rg 'search regex'
failed to read the file specified in RIPGREP_CONFIG_PATH: no_exist_path: No such file or directory (os error 2)
In the above examples, the first failure mode looks obvious, but that's
only because RIPGREP_CONFIG_PATH is being set at the same time that we
run the command. Often, the environment variable is set elsewhere and
the error message could be confusing outside of that context.
Closes#1990
Previously, the 'fut' type only matches files called '.fut', while in
reality we want to match all files with the '.fut' extension. This
commit fixes that issue.
PR #2027
It looks like it's possible for mmap to succeed on 32-bit systems even
when the full file can't be addressed in memory. This used to work prior
to ripgrep 13, but (maybe) something about statically linking vcruntime
has caused this to now fail.
It's no big deal to disable mmap searching on 32-bit, so we just do that
instead of returning incorrect results.
Fixes#1911
It sounds like Projectfile is no longer being used,
but we should keep it around in case folks are
still using it. It's unlikely that its presence will
do much if any harm.
PR #1904
This is a weird bug where our optimization for handling -w more quickly
than we would otherwise failed. In particular, if the original regex can
match the empty string, then our word boundary detection would produce
invalid indices to the start the next search at. We "fix" it by simply
bailing when the indices are known to be incorrect.
This wasn't a problem in a previous release since ripgrep 13 tweaked how
word boundaries are detected in commit efd9cfb2.
Fixes#1891
