This removes ripgrep-specific code for filtering files that correspond to
stdout and instead uses the 'ignore' crate's functionality for doing the
same.
This commit adds a new 'skip_stdout' option to the directory walker. When
enabled, it will skip yielding any directory entries that are believed to
correspond to stdout for the current process. This is useful for filtering
out 'results' in a command like 'grep -r foo > results' in order to avoid
an unbounded feedback mechanism.
These flags each accept one of five choices: none, path, modified,
accessed or created. The value indicates how the results are sorted.
For --sort, results are sorted in ascending order where as for --sortr,
results are sorted in descending order.
Closes#404
This permits callers to sort entries by their full file path, which makes
it easy to query for various file statistics.
It would have been better to provide a comparator on DirEntry itself,
similar to how walkdir does it, but this seems to require quite a bit of
work to make the types work out, assuming we want to continue to use
walkdir's sorting support (we do).
This commit adds a 'same_file_system' option to the walk builder. For
single threaded walking, it defers to the walkdir crate, which has the
same option. The bulk of this commit implements this flag for the parallel
walker. We add one very feeble test for this.
The parallel walker is now officially a complete mess.
Closes#321
This commit fixes a bug where the first path always reported itself as
as symlink via `path_is_symlink`.
Part of this fix includes updating walkdir to 2.2.1, which also includes
a corresponding bug fix.
Fixes#984
This commit beefs up the package metadata used by the 'cargo deb' tool to
produce a binary dpkg. In particular, we now include ripgrep's man page.
This commit includes a new script, 'ci/build_deb.sh', which will handle
the build process for a dpkg, which has become a bit more nuanced than
just running 'cargo deb'. We don't (yet) run this script in CI.
Fixes#842
This commit undoes a work-around for a bug in Rust's standard library
that prevented correct file type detection on Windows in OneDrive
directories. We remove the work-around because we are moving to a
latest-stable Rust version policy, which has included this fix for a while
now.
ref #705, https://github.com/rust-lang/rust/issues/46484
This also updates some code to make use of our more liberal versioning
requirement, including the use of crossbeam-channel instead of the MsQueue
from the older an unmaintained crossbeam 0.3. This does regrettably add
a sizable number of dependencies, however, compile times seem mostly
unaffected.
Closes#1019
Previously, we used --pcre2-unicode as the canonical flag despite the
fact that it is enabled by default, which is inconsistent with how we
handle other similar flags.
The reason why --pcre2-unicode was made the canonical flag was to make
it easier to discover since it would be sorted near the --pcre2 flag. To
solve that problem, we simply start a convention that lists related
flags in the docs.
Fixes#1022

This basically rewrites every integration test. We reduce the amount of
magic involved here in terms of which arguments are being passed to
ripgrep processes. To make up for the boiler plate saved by the magic,
we make the Dir (formerly WorkDir) type a bit nicer to use, along with a
new TestCommand that wraps a std::process::Command. In exchange, we get
tests that are easier to read and write.
We also run every test with the `--pcre2` flag to make sure that works,
when PCRE2 is available.
This commit does the work to delete the old `grep` crate and effectively
rewrite most of ripgrep core to use the new libripgrep crates. The new
`grep` crate is now a facade that collects the various crates that make
up libripgrep.
The most complex part of ripgrep core is now arguably the translation
between command line parameters and the library options, which is
ultimately where we want to be.
libripgrep is not any one library, but rather, a collection of libraries
that roughly separate the following key distinct phases in a grep
implementation:
1. Pattern matching (e.g., by a regex engine).
2. Searching a file using a pattern matcher.
3. Printing results.
Ultimately, both (1) and (3) are defined by de-coupled interfaces, of
which there may be multiple implementations. Namely, (1) is satisfied by
the `Matcher` trait in the `grep-matcher` crate and (3) is satisfied by
the `Sink` trait in the `grep2` crate. The searcher (2) ties everything
together and finds results using a matcher and reports those results
using a `Sink` implementation.
Closes#162
