ripgrep 12.0.0

on Rust Cargo

ripgrep 12 is a new major version release of ripgrep that contains many bug
fixes, several important performance improvements and a few minor new features.

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. By
default, ripgrep will respect your .gitignore and automatically skip hidden
files/directories and binary files.

In a near future release, I am hoping to add an
indexing feature
to ripgrep, which will dramatically speed up searching by building an index.
Feedback would very much be appreciated, especially on the user experience
which will be difficult to get right.

This release has no known breaking changes.

Deprecations:

• The --no-pcre2-unicode flag is deprecated. Instead, use the --no-unicode
  flag, which applies to both the default regex engine and PCRE2. For now,
  --no-pcre2-unicode and --pcre2-unicode are aliases to --no-unicode
  and --unicode, respectively. The --[no-]pcre2-unicode flags may be
  removed in a future release.
• The --auto-hybrid-regex flag is deprecated. Instead, use the new --engine
  flag with the auto value.

Performance improvements:

• PERF #1087:
  ripgrep is smarter when detected literals are whitespace.
• PERF #1381:
  Directory traversal is sped up with speculative ignore-file existence checks.
• PERF cd8ec38a:
  Improve inner literal detection to cover more cases more effectively.
  e.g., +Sherlock Holmes + now has Sherlock Holmes extracted instead
  of .
• PERF 6a0e0147:
  Improve literal detection when the -w/--word-regexp flag is used.
• PERF ad97e9c9:
  Improve overall performance of the -w/--word-regexp flag.

  Postscript, Skim, Slim, Slime, RPM Spec files, Typoscript, xml.
