15.1.0

This is a small release that fixes a bug with how ripgrep handles line buffering. This might manifest as ripgrep printing output later than you expect or not working correctly with tail -f (even if you're using the --line-buffered flag).

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

Bug fixes:

BUG #3194: Fix a regression with --line-buffered introduced in ripgrep 15.0.0.

Feature enhancements:

FEATURE #3192: Add hyperlink alias for Cursor.

15.0.0

Sponsorship is appreciated!

ripgrep 15 is a new major version release of ripgrep that mostly has bug fixes, some minor performance improvements and minor new features.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

Here are some highlights:

Several bugs around gitignore matching have been fixed. This includes a commonly reported bug related to applying gitignore rules from parent directories.
A memory usage regression when handling very large gitignore files has been fixed.
rg -vf file, where file is empty, now matches everything.
The -r/--replace flag now works with --json.
A subset of Jujutsu (jj) repositories are now treated as if they were git repositories. That is, ripgrep will respect jj's gitignores.
Globs can now use nested curly braces.

Platform support:

aarch64 for Windows now has release artifacts.
powerpc64 no longer has release artifacts generated for it. The CI release workflow stopped working, and I didn't deem it worth my time to debug it. If someone wants this and can test it, I'd be happy to add it back.
ripgrep binaries are now compiled with full LTO enabled. You may notice small performance improvements from this and a modest decrease in binary size.

Performance improvements:

PERF #2111: Don't resolve helper binaries on Windows when -z/--search-zip isn't used.
PERF #2865: Avoid using path canonicalization on Windows when emitting hyperlinks.
PERF #3184: Improve performance of large values with -A/--after-context.

14.1.1

Sponsorship is appreciated!

This is a minor release with a bug fix for a matching bug. In particular, a bug was found that could cause ripgrep to ignore lines that should match. That is, false negatives. It is difficult to characterize the specific set of regexes in which this occurs as it requires multiple different optimization strategies to collide and produce an incorrect result. But as one reported example, in ripgrep, the regex (?i:e.x|ex) does not match e-x when it should. (This bug is a result of an inner literal optimization performed in the grep-regex crate and not in the regex crate.)

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

14.0.0

Sponsorship is appreciated!

ripgrep 14 is a new major version release of ripgrep that has some new features, performance improvements and a lot of bug fixes.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

The headlining feature in this release is hyperlink support. In this release, they are an opt-in feature but may change to an opt-out feature in the future. To enable them, try passing --hyperlink-format default. If you use VS Code, then try passing --hyperlink-format vscode. Please report your experience with hyperlinks, positive or negative.

Another headlining development in this release is that it contains a rewrite of its regex engine. You generally shouldn't notice any changes, except for some searches may get faster. You can read more about the regex engine rewrite on my blog. Please report your performance improvements or regressions that you notice.

Finally, ripgrep switched the library it uses for argument parsing. Users should not notice a difference in most cases (error messages have changed somewhat), but flag overrides should generally be more consistent. For example, things like --no-ignore --ignore-vcs work as one would expect (disables all filtering related to ignore rules except for rules found in version control systems such as git).

BREAKING CHANGES:

rg -C1 -A2 used to be equivalent to rg -A2, but now it is equivalent to rg -B1 -A2. That is, -A and -B no longer completely override -C. Instead, they only partially override -C.

Build process changes:

ripgrep's shell completions and man page are now created by running ripgrep with a new --generate flag. For example, rg --generate man will write a man page in roff format on stdout. The release archives have not changed.
The optional build dependency on asciidoc or asciidoctor has been dropped. Previously, it was used to produce ripgrep's man page. ripgrep now owns this process itself by writing roff directly.

Performance improvements:

PERF #1746: Make some cases with inner literals faster.
PERF #1760: Make most searches with \b look-arounds (among others) much faster.
PERF #2591: Parallel directory traversal now uses work stealing for faster searches.

13.0.0

ripgrep 13 is a new major version release of ripgrep that primarily contains bug fixes, some performance improvements and a few minor breaking changes. There is also a fix for a security vulnerability on Windows (CVE-2021-3013).

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

Some highlights:

A new short flag, -., has been added. It is an alias for the --hidden flag, which instructs ripgrep to search hidden files and directories.

ripgrep is now using a new vectorized implementation of memmem, which accelerates many common searches. If you notice any performance regressions (or major improvements), I'd love to hear about them through an issue report!

Also, for Windows users targeting MSVC, Cargo will now build fully static executables of ripgrep. The release binaries for ripgrep 13 have been compiled using this configuration.

BREAKING CHANGES:

Binary detection output has changed slightly.

In this release, a small tweak has been made to the output format when a binary file is detected. Previously, it looked like this:

Binary file FOO matches (found "\0" byte around offset XXX)

Now it looks like this:

FOO: binary file matches (found "\0" byte around offset XXX)

vimgrep output in multi-line now only prints the first line for each match.

See issue 1866 for more discussion on this. Previously, every line in a match was duplicated, even when it spanned multiple lines. There are no changes to vimgrep output when multi-line mode is disabled.

In multi-line mode, --count is now equivalent to --count-matches.

This appears to match how pcre2grep implements --count. Previously, ripgrep would produce outright incorrect counts. Another alternative would be to simply count the number of lines---even if it's more than the number of matches---but that seems highly unintuitive.

FULL LIST OF FIXES AND IMPROVEMENTS:

Security fixes:

CVE-2021-3013: Fixes a security hole on Windows where running ripgrep with either the -z/--search-zip or --pre flags can result in running arbitrary executables from the current directory.
VULN #1773: This is the public facing issue tracking CVE-2021-3013. ripgrep's README now contains a section describing how to report a vulnerability.

Performance improvements:

PERF #1657: Check if a file should be ignored first before issuing stat calls.
PERF memchr#82: ripgrep now uses a new vectorized implementation of memmem.

12.1.1

ripgrep 12.1.1 is a patch release that fixes a couple small bugs. In particular, the ripgrep 12.1.0 release did not tag new releases for all of its in-tree dependencies. As a result, ripgrep built dependencies from crates.io would produce a different build than compiling ripgrep from source on the 12.1.0 tag. Namely, some crates like grep-cli had unreleased changes.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your gitignore rules and automatically skip hidden files/directories and binary files.

Bug fixes:

BUG #1581: Corrects some egregious markup output in --help.
BUG #1591: Mention the special $0 capture group in docs for the -r/--replace flag.
BUG #1602: Fix failing test resulting from out-of-sync dependencies.

12.1.0

ripgrep 12.1.0 is a small minor version release that mostly includes bug fixes and documentation improvements. This release also contains some important notices for downstream packagers.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files.

Notices for downstream ripgrep package maintainers:

Fish shell completions will be removed in the ripgrep 13 release. See #1577 for more details.
ripgrep has switched from a2x to asciidoctor to generate the man page. If asciidoctor is not present, then ripgrep will currently fall back to a2x. Support for a2x will be dropped in the ripgrep 13 release. See #1544 for more details.

Feature enhancements:

FEATURE #1547: Support decompressing .Z files via uncompress.

Bug fixes:

BUG #1252: Add a section on the --pre flag to the GUIDE.
BUG #1339: Improve error message when a pattern with invalid UTF-8 is provided.
BUG #1524: Note how to escape a $ when using --replace.
BUG #1537: Fix match bug caused by inner literal optimization.
BUG #1544: ripgrep now uses asciidoctor instead of a2x to generate its man page.
BUG #1550: Substantially reduce peak memory usage when searching wide directories.
BUG #1571: Add note about configuration files in --type-{add,clear} docs.
BUG #1573: Fix incorrect --count-matches output when using look-around.

12.0.1

ripgrep 12.0.1 is a small patch release that includes a minor bug fix relating to superfluous error messages when searching git repositories with sub-modules. This was a regression introduced in the 12.0.0 release.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files.

Bug fixes:

BUG #1520: Don't emit spurious error messages in git repositories with submodules.

12.0.0

ripgrep 12 is a new major version release of ripgrep that contains many bug fixes, several important performance improvements and a few minor new features.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files.

In a near future release, I am hoping to add an indexing feature to ripgrep, which will dramatically speed up searching by building an index. Feedback would very much be appreciated, especially on the user experience which will be difficult to get right.

This release has no known breaking changes.

Deprecations:

The --no-pcre2-unicode flag is deprecated. Instead, use the --no-unicode flag, which applies to both the default regex engine and PCRE2. For now, --no-pcre2-unicode and --pcre2-unicode are aliases to --no-unicode and --unicode, respectively. The --[no-]pcre2-unicode flags may be removed in a future release.
The --auto-hybrid-regex flag is deprecated. Instead, use the new --engine flag with the auto value.

Performance improvements:

PERF #1087: ripgrep is smarter when detected literals are whitespace.
PERF #1381: Directory traversal is sped up with speculative ignore-file existence checks.
PERF cd8ec38a: Improve inner literal detection to cover more cases more effectively. e.g., +Sherlock Holmes + now has Sherlock Holmes extracted instead of .
PERF 6a0e0147: Improve literal detection when the -w/--word-regexp flag is used.
PERF ad97e9c9: Improve overall performance of the -w/--word-regexp flag.

Feature enhancements:

Added or improved file type filtering for erb, diff, Gradle, HAML, Org, Postscript, Skim, Slim, Slime, RPM Spec files, Typoscript, xml.
FEATURE #1370: Add --include-zero flag that shows files searched without matches.
FEATURE #1390: Add --no-context-separator flag that always hides context separators.
FEATURE #1414: Add --no-require-git flag to allow ripgrep to respect gitignores anywhere.
FEATURE #1420: Add --no-ignore-exclude to disregard rules in .git/info/exclude files.
FEATURE #1466: Add --no-ignore-files flag to disable all --ignore-file flags.
FEATURE #1488: Add '--engine' flag for easier switching between regex engines.
FEATURE 75cbe88f: Add --no-unicode flag. This works on all supported regex engines.

Bug fixes:

BUG #1291: ripgrep now works in non-existent directories.
BUG #1319: Fix match bug due to errant literal detection.
BUG #1335: Fixes a performance bug when searching plain text files with very long lines. This was a serious performance regression in some cases.
BUG #1344: Document usage of --type all.
BUG #1389: Fixes a bug where ripgrep would panic when searching a symlinked directory.
BUG #1439: Improve documentation for ripgrep's automatic stdin detection.

BUG #1485: Fish shell completions from the release Debian package are now installed to /usr/share/fish/vendor_completions.d/rg.fish.

11.0.2

ripgrep 11.0.2 is a new patch release that fixes a few bugs, including a performance regression and a matching bug when using the -F/--fixed-strings flag.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files.

Feature enhancements:

FEATURE #1293: Added --glob-case-insensitive flag that makes --glob behave as --iglob.

Bug fixes:

BUG #1246: Add translations to README, starting with an unofficial Chinese translation.

BUG #1334: Fix match regression with -F flag when patterns contain meta characters.

11.0.1

ripgrep 11.0.1 is a new patch release that fixes a search regression introduced in the previous 11.0.0 release. In particular, ripgrep can enter an infinite loop for some search patterns when searching invalid UTF-8.

Bug fixes:

BUG #1247: Fix search bug that can cause ripgrep to enter an infinite loop.

11.0.0

ripgrep 11 is a new major version release of ripgrep that contains many bug fixes, some performance improvements and a few feature enhancements. Notably, ripgrep's user experience for binary file filtering has been improved. See the guide's new section on binary data for more details.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files.

This release also marks a change in ripgrep's versioning. Where as the previous version was 0.10.0, this version is 11.0.0. Moving forward, ripgrep's major version will be increased a few times per year. ripgrep will continue to be conservative with respect to backwards compatibility, but may occasionally introduce breaking changes, which will always be documented in this CHANGELOG. See issue 1172 for a bit more detail on why this versioning change was made.

This release increases the minimum supported Rust version from 1.28.0 to 1.34.0.

BREAKING CHANGES:

ripgrep has tweaked its exit status codes to be more like GNU grep's. Namely, if a non-fatal error occurs during a search, then ripgrep will now always emit a 2 exit status code, regardless of whether a match is found or not. Previously, ripgrep would only emit a 2 exit status code for a catastrophic error (e.g., regex syntax error). One exception to this is if ripgrep is run with -q/--quiet. In that case, if an error occurs and a match is found, then ripgrep will exit with a 0 exit status code.
Supplying the -u/--unrestricted flag three times is now equivalent to supplying --no-ignore --hidden --binary. Previously, -uuu was equivalent to --no-ignore --hidden --text. The difference is that --binary disables binary file filtering without potentially dumping binary data into your terminal. That is, rg -uuu foo should now be equivalent to grep -r foo.
The avx-accel feature of ripgrep has been removed since it is no longer necessary. All uses of AVX in ripgrep are now enabled automatically via runtime CPU feature detection. The simd-accel feature does remain available (only for enabling SIMD for transcoding), however, it does increase compilation times substantially at the moment.

Performance improvements:

PERF #497, PERF #838: Make rg -F -f dictionary-of-literals much faster.

Feature enhancements:

Added or improved file type filtering for Apache Thrift, ASP, Bazel, Brotli, BuildStream, bzip2, C, C++, Cython, gzip, Java, Make, Postscript, QML, Tex, XML, xz, zig and zstd.
FEATURE #855: Add --binary flag for disabling binary file filtering.
FEATURE #1078: Add --max-columns-preview flag for showing a preview of long lines.
FEATURE #1099: Add support for Brotli and Zstd to the -z/--search-zip flag.
FEATURE #1138: Add --no-ignore-dot flag for ignoring .ignore files.

0.10.0

ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern while respecting your gitignore rules. ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.

This is a new minor version release of ripgrep that contains some major new features, a huge number of bug fixes, and is the first release based on libripgrep. The entirety of ripgrep's core search and printing code has been rewritten and generalized so that anyone can make use of it.

Major new features include PCRE2 support, multi-line search and a JSON output format.

BREAKING CHANGES:

The minimum version required to compile Rust has now changed to track the latest stable version of Rust. Patch releases will continue to compile with the same version of Rust as the previous patch release, but new minor versions will use the current stable version of the Rust compile as its minimum supported version.
The match semantics of -w/--word-regexp have changed slightly. They used to be \b(?:<your pattern>)\b, but now it's (?:^|\W)(?:<your pattern>)(?:$|\W). This matches the behavior of GNU grep and is believed to be closer to the intended semantics of the flag. See #389 for more details.

Feature enhancements:

FEATURE #162: libripgrep is now a thing. The primary crate is grep.
FEATURE #176: Add -U/--multiline flag that permits matching over multiple lines.
FEATURE #188: Add -P/--pcre2 flag that gives support for look-around and backreferences.
FEATURE #244: Add --json flag that prints results in a JSON Lines format.
FEATURE #321: Add --one-file-system flag to skip directories on different file systems.
FEATURE #404: Add --sort and --sortr flag for more sorting. Deprecate --sort-files.
FEATURE #416: Add --crlf flag to permit $ to work with carriage returns on Windows.
FEATURE #917: The --trim flag strips prefix whitespace from all lines printed.
FEATURE #993: Add --null-data flag, which makes ripgrep use NUL as a line terminator.
FEATURE #997: The --passthru flag now works with the --replace flag.
FEATURE #1038-1: Add --line-buffered and --block-buffered for forcing a buffer strategy.
FEATURE #1038-2: Add --pre-glob for filtering files through the --pre flag.

Bug fixes:

BUG #2: Searching with non-zero context can now use memory maps if appropriate.
BUG #200: ripgrep will now stop correctly when its output pipe is closed.
BUG #389: The -w/--word-regexp flag now works more intuitively.
BUG #643: Detection of readable stdin has improved on Windows.
BUG #441, BUG #690, BUG #980: Matching empty lines now works correctly in several corner cases.
BUG #764: Color escape sequences now coalesce, which reduces output size.
BUG #842: Add man page to binary Debian package.
BUG #922: ripgrep is now more robust with respect to memory maps failing.
BUG #937: Color escape sequences are no longer emitted for empty matches.
BUG #940: Context from the --passthru flag should not impact process exit status.
BUG #984: Fixes bug in ignore crate where first path was always treated as a symlink.
BUG #990: Read stderr asynchronously when running a process.
BUG #1013: Add compile time and runtime CPU features to --version output.
BUG #1028: Don't complete bare pattern after -f in zsh.

0.9.0

This is a new minor version release of ripgrep that contains some minor new features and a panoply of bug fixes.

Releases provided on Github for x86_64 will now work on all target CPUs, and will also automatically take advantage of features found on modern CPUs (such as AVX2) for additional optimizations.

This release increases the minimum supported Rust version from 1.20.0 to 1.23.0.

It is anticipated that the next release of ripgrep (0.10.0) will provide multi-line search support and a JSON output format.

BREAKING CHANGES:

When --count and --only-matching are provided simultaneously, the behavior of ripgrep is as if the --count-matches flag was given. That is, the total number of matches is reported, where there may be multiple matches per line. Previously, the behavior of ripgrep was to report the total number of matching lines. (Note that this behavior diverges from the behavior of GNU grep.)
Octal syntax is no longer supported. ripgrep previously accepted expressions like \1 as syntax for matching U+0001, but ripgrep will now report an error instead.
The --line-number-width flag has been removed. Its functionality was not carefully considered with all ripgrep output formats. See #795 for more details.

Feature enhancements:

Added or improved file type filtering for Android, Bazel, Fuschia, Haskell, Java and Puppet.
FEATURE #411: Add a --stats flag, which emits aggregate statistics after search results.
FEATURE #646: Add a --no-ignore-messages flag, which suppresses parse errors from reading .ignore and .gitignore files.
FEATURE #702: Support \u{..} Unicode escape sequences.
FEATURE #812: Add -b/--byte-offset flag that shows the byte offset of each matching line.
FEATURE #814: Add --count-matches flag, which is like --count, but for each match.
FEATURE #880: Add a --no-column flag, which disables column numbers in the output.
FEATURE #898: Add support for lz4 when using the -z/--search-zip flag.
FEATURE #924: termcolor has moved to its own repository: https://github.com/BurntSushi/termcolor
FEATURE #934: Add a new flag, --no-ignore-global, that permits disabling global gitignores.
FEATURE #967: Rename --maxdepth to --max-depth for consistency. Keep --maxdepth for backwards compatibility.
FEATURE #978: Add a --pre option to filter inputs with an arbitrary program.
FEATURE fca9709d: Improve zsh completion.

Bug fixes:

BUG #135: Release portable binaries that conditionally use SSSE3, AVX2, etc., at runtime.
BUG #268: Print descriptive error message when trying to use look-around or backreferences.
BUG #395: Show comprehensible error messages for regexes like \s*{.

BUG #964: Add a --no-fixed-strings flag to disable -F/--fixed-strings.
BUG #988: Fix a bug in the ignore crate that prevented the use of explicit ignore files after disabling all other ignore rules.
BUG #995: Respect $XDG_CONFIG_DIR/git/config for detecting core.excludesFile.

0.8.1

This is a patch release of ripgrep that primarily fixes regressions introduced in 0.8.0 (#820 and #824) in directory traversal on Windows. These regressions do not impact non-Windows users.

Feature enhancements:

Added or improved file type filtering for csv and VHDL.
FEATURE #798: Add underline support to termcolor and ripgrep. See documentation on the --colors flag for details.

BUG #815: Clarify a common failure mode in user guide.
BUG #820: Fixes a bug on Windows where symlinks were followed even if not requested.
BUG #824: Fix a performance regression in directory traversal on Windows.

0.8.0

This is a new minor version releae of ripgrep that satisfies several popular feature requests (config files, search compressed files, true colors), fixes many bugs and improves the quality of life for ripgrep maintainers. This release also includes greatly improved documentation in the form of a User Guide and a FAQ.

This release increases the minimum supported Rust version from 1.17 to 1.20.

BREAKING CHANGES:

Note that these are all very minor and unlikely to impact most users.

In order to support configuration files, flag overrides needed to be rethought. In some cases, this changed ripgrep's behavior. For example, in ripgrep 0.7.1, rg foo -s -i will perform a case sensitive search since the -s/--case-sensitive flag was defined to always take precedence over the -i/--ignore-case flag, regardless of position. In ripgrep 0.8.0 however, the override rule for all flags has changed to "the most recent flag wins among competing flags." That is, rg foo -s -i now performs a case insensitive search.
The -M/--max-columns flag was tweaked so that specifying a value of 0 now makes ripgrep behave as if the flag was absent. This makes it possible to set a default value in a configuration file and then override it. The previous ripgrep behavior was to suppress all matching non-empty lines.
In all globs, [^...] is now equivalent to [!...] (indicating class negation). Previously, ^ had no special significance in a character class.
For downstream packagers, the directory hierarchy in ripgrep's archive releases has changed. The root directory now only contains the executable, README and license. There is now a new directory called doc which contains the man page (previously in the root), a user guide (new), a FAQ (new) and the CHANGELOG (previously not included in release). The complete directory remains the same.

Feature enhancements:

Added or improved file type filtering for Apache Avro, C++, GN, Google Closure Templates, Jupyter notebooks, man pages, Protocol Buffers, Smarty and Web IDL.
FEATURE #196: Support a configuration file. See the new user guide for details.
FEATURE #261: Add extended or "true" color support. Works in Windows 10! See the FAQ for details.

FEATURE #544: Add support for line number alignment via a new --line-number-width flag.
FEATURE #654: Support linuxbrew in ripgrep's Brew tap.
FEATURE #673: Bring back .rgignore files. (A higher precedent, application specific version of .ignore.)
FEATURE #676: Provide ARM binaries. WARNING: This will be provided on a best effort basis.
FEATURE #709: Suggest -F/--fixed-strings flag on a regex syntax error.
FEATURE #740: Add a --passthru flag that causes ripgrep to print every line it reads.
FEATURE #785: Overhaul documentation. Cleaned up README, added user guide and FAQ.
FEATURE 7f5c07: Add hidden flags for convenient overrides (e.g., --no-text).

Bug fixes:

BUG #553: Permit flags to be repeated.
BUG #633: Fix a bug where ripgrep would panic on Windows while following symlinks.
BUG #649: Fix handling of !**/ in .gitignore.
BUG #663: BREAKING CHANGE: Support [^...] glob syntax (as identical to [!...]).

BUG #705: Fix a bug that prevented ripgrep from searching OneDrive directories.
BUG #717: Improve --smart-case uppercase character detection.
BUG #725: Clarify that globs do not override explicitly given paths to search.
BUG #742: Write ANSI reset code as \x1B[0m instead of \x1B[m.
BUG #747: Remove yarn.lock from YAML file type.
BUG #760: ripgrep can now search /sys/devices/system/cpu/vulnerabilities/* files.
BUG #761: Fix handling of gitignore patterns that contain a /.
BUG #776: BREAKING CHANGE: --max-columns=0 now disables the limit.
BUG #779: Clarify documentation for --files-without-match.
BUG #780, BUG #781: Fix bug where ripgrep missed some matching lines.

Maintenance fixes:

Friends of ripgrep:

I'd like to extend my gratitude to @balajisivaraman for their recent hard work in a number of areas, and in particular, for implementing the "search compressed files" feature. Their work in sketching out a specification for that and other work has been exemplary.

Thanks @balajisivaraman!

0.5.0

This is a new minor version release of ripgrep that includes one minor breaking change, bug fixes and several new features including support for text encodings other than UTF-8.

A notable accomplishment with respect to Rust is that ripgrep proper now only contains a single unsafe use (for accessing the contents of a memory map).

The breaking change is:

FEATURE #380: Line numbers are now hidden by default when ripgrep is printing to a tty and the only thing searched is stdin.

Feature enhancements:

Added or improved file type filtering for Ceylon, CSS, Elixir, HTML, log, SASS, SVG, Twig
FEATURE #1: Add support for additional text encodings, including automatic detection for UTF-16 via BOM sniffing. Explicit text encoding support with the -E/--encoding flag was also added for latin-1, GBK, EUC-JP and Shift_JIS, among others. The full list can be found here: https://encoding.spec.whatwg.org/#concept-encoding-get
FEATURE #129: Add a new -M/--max-columns flag that omits lines longer than the given number of bytes. (Disabled by default!)
FEATURE #369: A new flag, --max-filesize, was added for limiting searches to files with a maximum file size.

Bug fixes:

BUG #52, BUG #311: Tweak how binary files are detected and handled. (We are slightly less conservative and will no longer use memory without bound.)
BUG #326: When --files flag is given, we should never attempt to parse positional arguments as regexes.

BUG #401: Add PowerShell completion file to Windows release.
BUG #405: Fix bug when excluding absolute paths with the -g/--glob flag.

0.4.0

This is a new minor version release of ripgrep that includes a couple very minor breaking changes, a few new features and lots of bug fixes.

This version of ripgrep upgrades its regex dependency from 0.1 to 0.2, which includes a few minor syntax changes:

POSIX character classes now require double bracketing. Previously, the regex [:upper:] would parse as the upper POSIX character class. Now it parses as the character class containing the characters :upper:. The fix to this change is to use [[:upper:]] instead. Note that variants like [[:upper:][:blank:]] continue to work.
The character [ must always be escaped inside a character class.
The characters &, - and ~ must be escaped if any one of them are repeated consecutively. For example, [&], [\&], [\&\&], [&-&] are all equivalent while [&&] is illegal. (The motivation for this and the prior change is to provide a backwards compatible path for adding character class set notation.)

Feature enhancements:

Added or improved file type filtering for Crystal, Kotlin, Perl, PowerShell, Ruby, Swig
FEATURE #83: Type definitions can now include other type definitions.
FEATURE #243: BREAKING CHANGE: The --column flag now implies --line-number.
FEATURE #263: Add a new --sort-files flag.
FEATURE #275: Add a new --path-separator flag. Useful in cygwin.

Bug fixes:

BUG #182: Redux: use more portable ANSI color escape sequences when possible.

BUG #262: Document how to install shell completion files.
BUG #268: Make lack of backreference support more explicit.
BUG #271: Remove ~ dependency on clap.
BUG #277: Fix cosmetic issue in globset crate docs.
BUG #279: ripgrep did not terminate when -q/--quiet was given.
BUG #281: BREAKING CHANGE: Completely remove ^C handling from ripgrep.
BUG #284: Make docs for -g/--glob clearer.
BUG #286: When stdout is redirected to a file, don't search that file.
BUG #287: Fix ZSH completions.
BUG #295: Remove superfluous memmap dependency in grep crate.
BUG #308: Improve docs for -r/--replace.

0.3.1

Bug fixes:

BUG #242: ripgrep didn't respect --colors foo:none correctly. Now it does.

0.3.0

This is a new minor version release of ripgrep that includes two breaking changes with lots of bug fixes and some new features and performance improvements. Notably, if you had a problem with colors or piping on Windows before, then that should now be fixed in this release.

BREAKING CHANGES:

ripgrep now requires Rust 1.11 to compile. Previously, it could build on Rust 1.9. The cause of this was the move from Docopt to Clap for argument parsing.
The -e/--regexp flag can no longer accept a pattern starting with a -. There are two work-arounds: rg -- -foo and rg [-]foo or rg -e [-]foo will all search for the same -foo pattern. The cause of this was the move from Docopt to Clap for argument parsing. This may get fixed in the future..

Performance improvements:

PERF #33: ripgrep now performs similar to GNU grep on small corpora.
PERF #136: ripgrep no longer slows down because of argument parsing when given a large argument list.

Feature enhancements:

Added or improved file type filtering for Elixir.
FEATURE #7: Add a -f/--file flag that causes ripgrep to read patterns from a file.
FEATURE #51: Add a --colors flag that enables one to customize the colors used in ripgrep's output.
FEATURE #138: Add a --files-without-match flag that shows only file paths that contain zero matches.
FEATURE #230: Add completion files to the release (Bash, Fish and PowerShell).

Bug fixes:

BUG #37: Use correct ANSI escape sequences when TERM=screen.linux.
BUG #94: ripgrep now detects stdin on Windows automatically.
BUG #117: Colors should now work correctly and automatically inside mintty.
BUG #182: Colors should now work within Emacs. In particular, --color=always will emit colors regardless of the current environment.
BUG #189: Show less content when running rg -h. The full help content can be accessed with rg --help.
BUG #210: Support non-UTF-8 file names on Unix platforms.
BUG #231: Switch from block buffering to line buffering.
BUG #241: Some error messages weren't suppressed when --no-messages was used.
