grep-printer

Bug fixes:

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

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.

Packaging updates:

• ripgrep is now in homebrew-core. brew install ripgrep will do the trick on a Mac.
• ripgrep is now in the Archlinux community repository. pacman -S ripgrep will do the trick on Archlinux.
• Support has been discontinued for i686-darwin.
• Glob matching has been moved out into its own crate: globset.

Feature enhancements:

• Added or improved file type filtering for CMake, config, Jinja, Markdown, Spark.
• FEATURE #109: Add a --max-depth flag for directory traversal.
• FEATURE #124: Add -s/--case-sensitive flag. Overrides --smart-case.
• FEATURE #139: The ripgrep repo is now a Homebrew tap. This is useful for installing SIMD accelerated binaries, which aren't available in homebrew-core.

Bug fixes:

• BUG #87, BUG #127, BUG #131: Various issues related to glob matching.
• BUG #116: --quiet should stop search after first match.
• BUG #121: --color always should show colors, even when --vimgrep is used.
• BUG #122: Colorize file path at beginning of line.
• BUG #134: Processing a large ignore file (thousands of globs) was very slow.
• BUG #137: Always follow symlinks when given as an explicit argument.
• BUG #147: Clarify documentation for --replace.

Feature enhancements:

• Added or improved file type filtering for Clojure and SystemVerilog.
• FEATURE #89: Add a --null flag that outputs a NUL byte after every file path.

Bug fixes:

• BUG #98: Fix a bug in single threaded mode when if opening a file failed, ripgrep quit instead of continuing the search.
• BUG #99: Fix another bug in single threaded mode where empty lines were being printed by mistake.
• BUG #105: Fix an off-by-one error with --column.
• BUG #106: Fix a bug where a whitespace only line in a gitignore file caused ripgrep to panic (i.e., crash).

Feature enhancements:

• Added or improved file type filtering for VB, R, F#, Swift, Nim, JavaScript, TypeScript
• FEATURE #20: Adds a --no-filename flag.
• FEATURE #26: Adds --files-with-matches flag. Like --count, but only prints file paths and doesn't need to count every match.
• FEATURE #40: Switch from using .rgignore to .ignore. Note that .rgignore is still supported, but deprecated.
• FEATURE #68: Add --no-ignore-vcs flag that ignores .gitignore but not .ignore.
• FEATURE #70: Add -S/--smart-case flag (but is disabled by default).
• FEATURE #80: Add support for {foo,bar} globs.

Many many bug fixes. Thanks every for reporting these and helping make ripgrep better! (Note that I haven't captured every tracking issue here, some were closed as duplicates.)

• BUG #8: Don't use an intermediate buffer when --threads=1. (Permits constant memory usage.)
• BUG #15: Improves the documentation for --type-add.
• BUG #16, BUG #49, BUG #50, BUG #65: Some gitignore globs were being treated as anchored when they weren't.
• BUG #18: --vimgrep reported incorrect column number.
• BUG #19: ripgrep was hanging waiting on stdin in some Windows terminals. Note that this introduced a new bug: #94.
• BUG #21: Removes leading ./ when printing file paths.
• BUG #22: Running rg --help | echo caused rg to panic.
• BUG #24: Clarify the central purpose of rg in its usage message.
• BUG #25: Anchored gitignore globs weren't applied in subdirectories correctly.
• BUG #30: Globs like foo/** should match contents of foo, but not foo itself.
• BUG #35, BUG #81: When automatically detecting stdin, only read if it's a file or a fifo. i.e., ignore stdin in rg foo < /dev/null.
• BUG #36: Don't automatically pick memory maps on MacOS. Ever.
• BUG #38: Trailing whitespace in gitignore wasn't being ignored.
• BUG #43: --glob didn't work with directories.
• BUG #46: Use one fewer worker thread than what is provided on CLI.
• BUG #47: --help/--version now work even if other options are set.
• BUG #55: ripgrep was refusing to search /proc/cpuinfo. Fixed by disabling memory maps for files with zero size.
• BUG #64: The first path given with --files set was ignored.
• BUG #67: Sometimes whitelist globs like !/dir weren't interpreted as anchored.
• BUG #77: When -q/--quiet flag was passed, ripgrep kept searching even after a match was found.
• BUG #90: Permit whitelisting hidden files.
• BUG #93: ripgrep was extracting an erroneous inner literal from a repeated pattern.
