ripgrep v0.4.0 Release Notes

  • 🚀 This is a new minor version release of ripgrep that includes a couple very 🛠 minor breaking changes, a few new features and lots of bug fixes.

    ⬆️ This version of ripgrep upgrades its regex dependency from 0.1 to 0.2, which includes a few minor syntax changes:

    • POSIX character classes now require double bracketing. Previously, the regex [:upper:] would parse as the upper POSIX character class. Now it parses as the character class containing the characters :upper:. The fix to this change is to use [[:upper:]] instead. Note that variants like [[:upper:][:blank:]] continue to work.
    • The character [ must always be escaped inside a character class.
    • The characters &, - and ~ must be escaped if any one of them are repeated consecutively. For example, [&], [\&], [\&\&], [&-&] are all equivalent while [&&] is illegal. (The motivation for this and the prior change is to provide a backwards compatible path for adding character class set notation.)
