This commit removes the previous smart case detection logic and replaces
it with detection based on the regex AST. This particular AST is a faithful
representation of the concrete syntax, which lets us be very precise in
how we handle it.
Closes#851
This update brings with it many bug fixes:
* Better error messages are printed overall. We also include
explicit call out for unsupported features like backreferences
and look-around.
* Regexes like `\s*{` no longer emit incomprehensible errors.
* Unicode escape sequences, such as `\u{..}` are now supported.
For the most part, this upgrade was done in a straight-forward way. We
resist the urge to refactor the `grep` crate, in anticipation of it
being rewritten anyway.
Note that we removed the `--fixed-strings` suggestion whenever a regex
syntax error occurs. In practice, I've found that it results in a lot of
false positives, and I believe that its use is not as paramount now that
regex parse errors are much more readable.
Closes#268, Closes#395, Closes#702, Closes#853
This update brings with it a new feature of the regex crate which will
now use SIMD optimizations automatically at runtime with no necessary
compile time flags. All that's needed is to enable the `unstable` feature.
Other crates, such as bytecount and encoding_rs, are still using the
old-style SIMD support, so we leave the simd-accel and avx-accel features.
However, the binaries we distribute on Github no longer have those
features enabled, which makes them truly portable.
Fixes#135
This commit provides basic support for a --stats flag, which will print
various aggregate statistics about a search after all of the results
have been printed. This is mostly intended to support a similar feature
found in the Silver Searcher. Note though that we don't emit the total
bytes searched; this is a first pass at an implementation and we can
improve upon it later.
Closes#411, Closes#799
Namely, when ripgrep is asked to count things and is also asked to print
every match on its own line, then we should just automatically count the
matches and not the lines. This is a departure from how GNU grep behaves,
but there is a compelling argument to be made that GNU grep's behavior
doesn't make a lot of sense.
Note that since this changes the behavior of combining two existing
flags, this is a breaking change.
This commit introduces a new flag, --count-matches, which will cause
ripgrep to report a total count of all matches instead of a count of
total lines matched.
Closes#566, Closes#814
This commit adds support for printing 0-based byte offset before each
line. We handle corner cases such as `-o/--only-matching` and
`-C/--context` as well.
Closes#812
Use the new `Globset::backslash_escape` knob to conform to git behavior:
`\` will escape the following character. For example, the pattern `\*`
will match a file literally named `*`.
Also tweak a test in ripgrep that was relying on this incorrect
behavior.
Closes#526, Closes#811
This commit makes the ErrorKind enum extensible by adding a
__Nonexhaustive variant. Callers should use this as a hint that
exhaustive case analysis isn't possible in a stable way since new
variants may be added in the future without a semver bump.
From `man 7 glob`:
One can remove the special meaning of '?', '*' and '[' by preceding
them by a backslash, or, in case this is part of a shell command
line, enclosing them in quotes.
Conform to glob / fnmatch / git implementations by making `\` escape the
following character - for example `\?` will match a literal `?`.
However, only enable this by default on Unix platforms. Windows builds
will continue to use `\` as a path separator, but can still get the new
behavior by calling `globset.backslash_escape(true)`.
Adding tests for the `Globset::backslash_escape` option was a bit
involved, since the default value of this option is platform-dependent.
Extend the options framework to hold an `Option<T>` for each
knob, where `None` means "default" and `Some(v)` means "override with
`v`". This way we only have to specify the default values once in
`GlobOptions::default()` rather than replicated in both code and tests.
Finally write a few behavioral tests, and some tests to confirm it
varies by platform.
This fixes a bug where ripgrep's man page wasn't generated in the ARM
cross-compile build. Mostly, this should just require installing
asciidoc and making sure we test that it actually works.
Fixes#791
This adds a hint for end users that run into a common failure mode where
ripgrep won't search any files because they have a `*` rule in their
`$HOME/.gitignore`.
Fixes#815
This commit fixes a performance regression in Windows that resulted from
fallout from fixing #705. In particular, we introduced an additional
stat call for every single directory entry, which can be quite
disastrous for performance.
There is a corresponding companion PR that fixes the same bug in
walkdir: https://github.com/BurntSushi/walkdir/pull/96Fixes#820
This commit fixes a bug where symlinks were always being followed on
Windows, even if the user did not request it. This only impacts the
parallel iterator.
This is a regression from the fallout of fixing #705.
Fixes#824
Generating a Debian binary package was pretty easy using `cargo deb`, so
it is now part of the release. This commit updates the README's
installation methods to reference it.
I did look into setting up a PPA for Ubuntu, but my eyes glazed over while
reading the documentation. Providing a binary Debian package is likely a
faux pas, but it is extraordinarily convenient.
This commit fixes a bug where `rg --hidden .` would behave differently
with respect to ignore filtering than `rg --hidden ./`. In particular,
this was due to a bug where the directory name `.` caused the leading
`.` in a hidden directory to get stripped, which in turn caused the
ignore rules to fail.
Fixes#807
This commit fixes a bug in the handling of custom gitignore file names.
Previously, the directory walker would check for whether there were any
ignore rules present, but this check didn't incorporate the custom gitignore
rules. At a high level, this permits custom gitignore names to be used
even if no other source of gitignore rules is used.
Fixes#800
