📄 Description

Bumps regex from 1.8.4 to 1.9.1.

Changelog

Sourced from regex's changelog.

1.9.1 (2023-07-07)

This is a patch release which fixes a memory usage regression. In the regex 1.9 release, one of the internal engines used a more aggressive allocation strategy than what was done previously. This patch release reverts to the prior on-demand strategy.

Bug fixes:

[BUG #1027](rust-lang/regex#1027): Change the allocation strategy for the backtracker to be less aggressive.

1.9.0 (2023-07-05)

This release marks the end of a years long rewrite of the regex crate internals. Since this is such a big release, please report any issues or regressions you find. We would also love to hear about improvements as well.

In addition to many internal improvements that should hopefully result in "my regex searches are faster," there have also been a few API additions:

A new Captures::extract method for quickly accessing the substrings that match each capture group in a regex.

A new inline flag, R, which enables CRLF mode. This makes . match any Unicode scalar value except for \r and \n, and also makes (?m:^) and (?m:$) match after and before both \r and \n, respectively, but never between a \r and \n.

RegexBuilder::line_terminator was added to further customize the line terminator used by (?m:^) and (?m:$) to be any arbitrary byte.

The std Cargo feature is now actually optional. That is, the regex crate can be used without the standard library.

Because regex 1.9 may make binary size and compile times even worse, a new experimental crate called regex-lite has been published. It prioritizes binary size and compile times over functionality (like Unicode) and performance. It shares no code with the regex crate.

New features:

[FEATURE #244](rust-lang/regex#244): One can opt into CRLF mode via the R flag. e.g., (?mR:$) matches just before \r\n.

[FEATURE #259](rust-lang/regex#259): Multi-pattern searches with offsets can be done with regex-automata 0.3.

[FEATURE #476](rust-lang/regex#476): std is now an optional feature. regex may be used with only alloc.

[FEATURE #644](rust-lang/regex#644): RegexBuilder::line_terminator configures how (?m:^) and (?m:$) behave.

[FEATURE #675](rust-lang/regex#675):

... (truncated)
