Upstream deprecated env::home_dir because of minor bugs in some corner
cases. We should probably eventually migrate to a correct implementation
in the `dirs` crate, but using the buggy version is just fine for now.
This commit removes an unconditional extra regex search that is in fact
not always necessary. This can result in a 2x performance improvement in
cases where ripgrep reports many matches.
The fix itself isn't ideal, but we continue to punt on cleaning up the
printer until it is rewritten for libripgrep, which is happening Real
Soon Now.
Fixes#955
Specifically, this will use a buffered writer when not printing to a tty.
This fixes a long standing performance regression where ripgrep would
slow down dramatically if it needed to report a lot of matches.
Fixes#955
This commit adds a new type, BufferedStandardStream, which emulates the
StandardStream API (sans `lock`), but will internally use a buffered
writer.
To achieve this, we add a new default method to the WriteColor trait that
indicates whether the underlying writer must synchronously communicate
with an API to control coloring (e.g., the Windows console API). The new
BufferedStandardStream then uses this default method to determine how
eager it should be to flush its buffer before employing color settings.
This should have basically zero overhead when using ANSI color escape
sequences.
This causes SIMD to kick in automatically when compiling with stable
Rust 1.27+.
We also update the README to describe the current state of things.

This commit updates the OverrideBuilder and GitignoreBuilder docs
for the case_insensitive method, denoting that it must be called before
adding any patterns.
Snap has caused a number of nonsensical bug reports, and not even the
`--classic` flag seems capable of fixing them. Therefore, remove snap
from the README and put in a special line in the ISSUE_TEMPLATE about
snap.

Puppet is primarily written in it's own format of .pp files, but
custom facts and functions are often written in Ruby. The templating
language is ERB and so this will allow scanning of any of the three
most commonly used formats for Puppet specific things.
This commit makes Gitignore::empty a bit faster by avoiding allocation
and manually specializing the implementation instead of routing it through
the GitignoreBuilder.
This helps improve uses of ripgrep that traverse *many* directories, and
in particular, when the use of ignores is disabled via command line
switches.
Fixes#835, Closes#836
A bug in the atty crate was previously masking a problem with the
integration tests on Windows. Namely, the bug in atty resulted in
atty::is(Stdin) returning true if we couldn't get the file name for the
stdin stream. This in turn caused tests like `rg foo` to search the CWD,
which was the intended behavior. However, once the atty bug was fixed,
atty::is(Stdin) no longer returned true, causing `rg foo` searches to
fail.
On Unix-like systems, the atty behavior has always been correct.
However, on Unix-like systems we have a decent way of detecting whether
stdin is readable or not. If it isn't---which is the case in the
integration tests---then we fall back to searching the CWD. On Windows
however, we haven't yet implemented anything to detect whether stdin is
readable or not, so we must always assume that it is. Therefore, we
never get the "go ahead" to search the CWD and the tests fail.
Most of the tests are written to search the CWD explicitly, but there
were a few stragglers that don't.
This isn't great, and we should try to figure out how to do better stdin
detection on Windows.
This commit does what no software project has ever done before: we've
outright removed a flag with no possible way to recapture its
functionality.
This flag presents numerous problems in that it never really worked well
in the first place, and completely falls over when ripgrep uses the
--no-heading output format. Well meaning users want ripgrep to fix this
by getting into the alignment business by buffering all output, but that
is a line that I refuse to cross.
Fixes#795
The new --no-ignore-messages flag permits suppressing errors related to
parsing .gitignore or .ignore files. These error messages can be somewhat
annoying since they can surface from repositories that one has no control
over.
Fixes#646
This makes it clear that the --no-messages flag doesn't actually
suppress all error messages, and is therefore not equivalent to
redirecting stderr to /dev/null.
See also: #860
There is a small hiccup here in that a `DirEntry` can embed errors
associated with reading an ignore file, which can be accessed and logged
by consumers if desired. That error type can contain an io::Error, which
isn't cloneable. We therefore implement Clone on our library's error
type in a way that re-creates the I/O error as best as possible.
Fixes#891
atty 0.2.7 (and 0.2.8) contain a regression in cygwin terminals that
prevents basic use of ripgrep, and is also the cause of the Windows CI
test failures. For now, we pin to 0.2.6, but a patch has been submitted
upstream: https://github.com/softprops/atty/pull/25
It would be nicer to switch to the `ripgrep` snap package, but
apparently it is configured to install with a binary name `ripgrep.rg`
instead of just `rg`. *sigh*
