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.

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.
  • FEATURE #1404:
    ripgrep now prints a warning if nothing is searched.
  • FEATURE #1613:
    Cargo will now produce static executables on Windows when using MSVC.

  • FEATURE #1856:
    The README now links to a
    Spanish translation.

Bug fixes:

  • BUG #1277:
    Document cygwin path translation behavior in the FAQ.
  • BUG #1739:

  • BUG #1765:
    Fix panic when --crlf is used in some cases.
  • BUG #1638:

  • BUG #1847:
    Clarify how the --hidden flag works.
  • BUG #1866:
    Fix bug when computing column numbers in --vimgrep mode.
  • BUG #1868:

  • BUG #1869:
    Clarify docs for --files-with-matches and --files-without-match.
  • BUG #1878:
    Fix bug where \A could produce unanchored matches in multiline search.
