The --pre-glob flag is like the --glob flag, except it applies to filtering
files through the preprocessor instead of for search. This makes it
possible to apply the preprocessor to only a small subset of files, which
can greatly reduce the process overhead of using a preprocessor when
searching large directories.
These flags provide granular control over ripgrep's buffering strategy.
The --line-buffered flag can be genuinely useful in certain types of shell
pipelines. The --block-buffered flag has a murkier use case, but we add it
for completeness.
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 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
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 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.
This commit adds a new --no-ignore-global flag that permits disabling
the use of global gitignore filtering. Global gitignores are generally
found in `$HOME/.config/git/ignore`, but its location can be configured
via git's `core.excludesFile` option.
Closes#934
The preprocessor flag accepts a command program and executes this
program for every input file that is searched. Instead of searching the
file directly, ripgrep will instead search the stdout contents of the
program.
Closes#978, Closes#981
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
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
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
This commit adds support for reading configuration files that change
ripgrep's default behavior. The format of the configuration file is an
"rc" style and is very simple. It is defined by two rules:
1. Every line is a shell argument, after trimming ASCII whitespace.
2. Lines starting with '#' (optionally preceded by any amount of
ASCII whitespace) are ignored.
ripgrep will look for a single configuration file if and only if the
RIPGREP_CONFIG_PATH environment variable is set and is non-empty.
ripgrep will parse shell arguments from this file on startup and will
behave as if the arguments in this file were prepended to any explicit
arguments given to ripgrep on the command line.
For example, if your ripgreprc file contained a single line:
--smart-case
then the following command
RIPGREP_CONFIG_PATH=wherever/.ripgreprc rg foo
would behave identically to the following command
rg --smart-case foo
This commit also adds a new flag, --no-config, that when present will
suppress any and all support for configuration. This includes any future
support for auto-loading configuration files from pre-determined paths
(which this commit does not add).
Conflicts between configuration files and explicit arguments are handled
exactly like conflicts in the same command line invocation. That is,
this command:
RIPGREP_CONFIG_PATH=wherever/.ripgreprc rg foo --case-sensitive
is exactly equivalent to
rg --smart-case foo --case-sensitive
in which case, the --case-sensitive flag would override the --smart-case
flag.
Closes#196
This commit adds opt-in support for searching compressed files during
recursive search. This behavior is only enabled when the
`-z/--search-zip` flag is passed to ripgrep. When enabled, a limited set
of common compression formats are recognized via file extension, and a
new process is spawned to perform the decompression. ripgrep then
searches the stdout of that spawned process.
Closes#539
The --passthru flag causes ripgrep to print every line,
even if the line does not contain a match. This is a
response to the common pattern of `^|foo` to match every
line, while still highlighting things like `foo`.
Fixes#740
