v1.10.4

Compare Source

v1.10.3

Compare Source

=================== This is a new patch release that fixes the feature configuration of optional dependencies, and fixes an unsound use of bounds check elision.

Bug fixes:

• BUG #​1147: Set default-features=false for the memchr and aho-corasick dependencies.
• BUG #​1154: Fix unsound bounds check elision.

v1.10.2

Compare Source

=================== This is a new patch release that fixes a search regression where incorrect matches could be reported.

Bug fixes:

• BUG #​1110: Revert broadening of reverse suffix literal optimization introduced in 1.10.1.

v1.10.1

Compare Source

=================== This is a new patch release with a minor increase in the number of valid patterns and a broadening of some literal optimizations.

New features:

• FEATURE 04f5d7be: Loosen ASCII-compatible rules such that regexes like (?-u:☃) are now allowed.

Performance improvements:

• PERF 8a8d599f: Broader the reverse suffix optimization to apply in more cases.

v1.10.0

Compare Source

=================== This is a new minor release of regex that adds support for start and end word boundary assertions. That is, \< and \>. The minimum supported Rust version has also been raised to 1.65, which was released about one year ago.

The new word boundary assertions are:

• \< or \b{start}: a Unicode start-of-word boundary (\W|\A on the left, \w on the right).
• \> or \b{end}: a Unicode end-of-word boundary (\w on the left, \W|\z on the right)).
• \b{start-half}: half of a Unicode start-of-word boundary (\W|\A on the left).
• \b{end-half}: half of a Unicode end-of-word boundary (\W|\z on the right).

The \< and \> are GNU extensions to POSIX regexes. They have been added to the regex crate because they enjoy somewhat broad support in other regex engines as well (for example, vim). The \b{start} and \b{end} assertions are aliases for \< and \>, respectively.

The \b{start-half} and \b{end-half} assertions are not found in any other regex engine (although regex engines with general look-around support can certainly express them). They were added principally to support the implementation of word matching in grep programs, where one generally wants to be a bit more flexible in what is considered a word boundary.

New features:

• FEATURE #​469: Add support for \< and \> word boundary assertions.
• FEATURE(regex-automata) #​1031: DFAs now have a start_state method that doesn't use an Input.

Performance improvements:

• PERF #​1051: Unicode character class operations have been optimized in regex-syntax.
• PERF #​1090: Make patterns containing lots of literal characters use less memory.

Bug fixes:

• BUG #​1046: Fix a bug that could result in incorrect match spans when using a Unicode word boundary and searching non-ASCII strings.
• BUG(regex-syntax) #​1047: Fix panics that can occur in Ast->Hir translation (not reachable from regex crate).
• BUG(regex-syntax) #​1088: Remove guarantees in the API that connect the u flag with a specific HIR representation.

regex-automata breaking change release:

This release includes a regex-automata 0.4.0 breaking change release, which was necessary in order to support the new word boundary assertions. For example, the Look enum has new variants and the LookSet type now uses u32 instead of u16 to represent a bitset of look-around assertions. These are overall very minor changes, and most users of regex-automata should be able to move to 0.4 from 0.3 without any changes at all.

regex-syntax breaking change release:

This release also includes a regex-syntax 0.8.0 breaking change release, which, like regex-automata, was necessary in order to support the new word boundary assertions. This release also includes some changes to the Ast type to reduce heap usage in some cases. If you are using the Ast type directly, your code may require some minor modifications. Otherwise, users of regex-syntax 0.7 should be able to migrate to 0.8 without any code changes.

regex-lite release:

The regex-lite 0.1.1 release contains support for the new word boundary assertions. There are no breaking changes.
