ripgrep v13.0.0 Release Notes

Release Date: 2021-06-12 // about 3 years ago
  • 🚀 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).

    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.


    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.


    🔒 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 memchr#82: ripgrep now uses a new vectorized implementation of memmem.

    🔋 Feature enhancements:

    • ➕ Added or improved file type filtering for ASP, Bazel, dvc, FlatBuffers, Futhark, minified files, Mint, pofiles (from GNU gettext) Racket, Red, Ruby, VCL, Yang.

Previous changes from v12.1.1

  • 🚀 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
    🏗 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.
    0️⃣ 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.
