ripgrep v0.9.0 Release Notes

Release Date: 2018-08-03 // over 5 years ago

  • 🚀 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, Fuchsia, 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 #955: Use buffered writing when not printing to a tty, which fixes a performance regression.
