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


  • 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.
