rust-lang/regex (regex)

### [`v1.9.0`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#190-2023-07-05) [Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.4...1.9.0) \================== This release marks the end of a [years long rewrite of the regex crate internals](https://togithub.com/rust-lang/regex/issues/656). 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](https://togithub.com/rust-lang/regex/issues/244): One can opt into CRLF mode via the `R` flag. e.g., `(?mR:$)` matches just before `\r\n`. - [FEATURE #259](https://togithub.com/rust-lang/regex/issues/259): Multi-pattern searches with offsets can be done with `regex-automata 0.3`. - [FEATURE #476](https://togithub.com/rust-lang/regex/issues/476): `std` is now an optional feature. `regex` may be used with only `alloc`. - [FEATURE #644](https://togithub.com/rust-lang/regex/issues/644): `RegexBuilder::line_terminator` configures how `(?m:^)` and `(?m:$)` behave. - [FEATURE #675](https://togithub.com/rust-lang/regex/issues/675): Anchored search APIs are now available in `regex-automata 0.3`. - [FEATURE #824](https://togithub.com/rust-lang/regex/issues/824): Add new `Captures::extract` method for easier capture group access. - [FEATURE #961](https://togithub.com/rust-lang/regex/issues/961): Add `regex-lite` crate with smaller binary sizes and faster compile times. - [FEATURE #1022](https://togithub.com/rust-lang/regex/pull/1022): Add `TryFrom` implementations for the `Regex` type. Performance improvements: - [PERF #68](https://togithub.com/rust-lang/regex/issues/68): Added a one-pass DFA engine for faster capture group matching. - [PERF #510](https://togithub.com/rust-lang/regex/issues/510): Inner literals are now used to accelerate searches, e.g., `\w+@\w+` will scan for `@`. - [PERF #787](https://togithub.com/rust-lang/regex/issues/787), [PERF #891](https://togithub.com/rust-lang/regex/issues/891): Makes literal optimizations apply to regexes of the form `\b(foo|bar|quux)\b`. (There are many more performance improvements as well, but not all of them have specific issues devoted to them.) Bug fixes: - [BUG #429](https://togithub.com/rust-lang/regex/issues/429): Fix matching bugs related to `\B` and inconsistencies across internal engines. - [BUG #517](https://togithub.com/rust-lang/regex/issues/517): Fix matching bug with capture groups. - [BUG #579](https://togithub.com/rust-lang/regex/issues/579): Fix matching bug with word boundaries. - [BUG #779](https://togithub.com/rust-lang/regex/issues/779): Fix bug where some regexes like `(re)+` were not equivalent to `(re)(re)*`. - [BUG #850](https://togithub.com/rust-lang/regex/issues/850): Fix matching bug inconsistency between NFA and DFA engines. - [BUG #921](https://togithub.com/rust-lang/regex/issues/921): Fix matching bug where literal extraction got confused by `$`. - [BUG #976](https://togithub.com/rust-lang/regex/issues/976): Add documentation to replacement routines about dealing with fallibility. - [BUG #1002](https://togithub.com/rust-lang/regex/issues/1002): Use corpus rejection in fuzz testing. ### [`v1.8.4`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#184-2023-06-05) [Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.3...1.8.4) \================== This is a patch release that fixes a bug where `(?-u:\B)` was allowed in Unicode regexes, despite the fact that the current matching engines can report match offsets between the code units of a single UTF-8 encoded codepoint. That in turn means that match offsets that split a codepoint could be reported, which in turn results in panicking when one uses them to slice a `&str`. This bug occurred in the transition to `regex 1.8` because the underlying syntactical error that prevented this regex from compiling was intentionally removed. That's because `(?-u:\B)` will be permitted in Unicode regexes in `regex 1.9`, but the matching engines will guarantee to never report match offsets that split a codepoint. When the underlying syntactical error was removed, no code was added to ensure that `(?-u:\B)` didn't compile in the `regex 1.8` transition release. This release, `regex 1.8.4`, adds that code such that `Regex::new(r"(?-u:\B)")` returns to the `regex <1.8` behavior of not compiling. (A `bytes::Regex` can still of course compile it.) Bug fixes: - [BUG #1006](https://togithub.com/rust-lang/regex/issues/1006): Fix a bug where `(?-u:\B)` was allowed in Unicode regexes, and in turn could lead to match offsets that split a codepoint in `&str`. ### [`v1.8.3`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#183-2023-05-25) [Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.2...1.8.3) \================== This is a patch release that fixes a bug where the regex would report a match at every position even when it shouldn't. This could occur in a very small subset of regexes, usually an alternation of simple literals that have particular properties. (See the issue linked below for a more precise description.) Bug fixes: - [BUG #999](https://togithub.com/rust-lang/regex/issues/999): Fix a bug where a match at every position is erroneously reported. ### [`v1.8.2`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#182-2023-05-22) [Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.1...1.8.2) \================== This is a patch release that fixes a bug where regex compilation could panic in debug mode for regexes with large counted repetitions. For example, `a{2147483516}{2147483416}{5}` resulted in an integer overflow that wrapped in release mode but panicking in debug mode. Despite the unintended wrapping arithmetic in release mode, it didn't cause any other logical bugs since the errant code was for new analysis that wasn't used yet. Bug fixes: - [BUG #995](https://togithub.com/rust-lang/regex/issues/995): Fix a bug where regex compilation with large counted repetitions could panic. ### [`v1.8.1`](https://togithub.com/rust-lang/regex/blob/HEAD/CHANGELOG.md#181-2023-04-21) [Compare Source](https://togithub.com/rust-lang/regex/compare/1.8.0...1.8.1) \================== This is a patch release that fixes a bug where a regex match could be reported where none was found. Specifically, the bug occurs when a pattern contains some literal prefixes that could be extracted *and* an optional word boundary in the prefix. Bug fixes: - [BUG #981](https://togithub.com/rust-lang/regex/issues/981): Fix a bug where a word boundary could interact with prefix literal optimizations and lead to a false positive match.
