v1.10.0Compare Source
===================
This is a new minor release of
regexthat adds support for start and endword boundary assertions. That is,
\<and\>. The minimum supported Rustversion 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|\Aon the left,\won the right).\>or\b{end}: a Unicode end-of-word boundary (\won the left,\W|\zon the right)).
\b{start-half}: half of a Unicode start-of-word boundary (\W|\Aon theleft).
\b{end-half}: half of a Unicode end-of-word boundary (\W|\zon theright).
The
\<and\>are GNU extensions to POSIX regexes. They have been addedto the
regexcrate because they enjoy somewhat broad support in other regexengines as well (for example, vim). The
\b{start}and\b{end}assertionsare aliases for
\<and\>, respectively.The
\b{start-half}and\b{end-half}assertions are not found in anyother 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:
Add support for
\<and\>word boundary assertions.DFAs now have a
start_statemethod that doesn't use anInput.Performance improvements:
Unicode character class operations have been optimized in
regex-syntax.Make patterns containing lots of literal characters use less memory.
Bug fixes:
Fix a bug that could result in incorrect match spans when using a Unicode word
boundary and searching non-ASCII strings.
Fix panics that can occur in
Ast->Hirtranslation (not reachable fromregexcrate).
Remove guarantees in the API that connect the
uflag with a specific HIRrepresentation.
regex-automatabreaking change release:This release includes a
regex-automata 0.4.0breaking change release, whichwas necessary in order to support the new word boundary assertions. For
example, the
Lookenum has new variants and theLookSettype now usesu32instead of
u16to represent a bitset of look-around assertions. These areoverall very minor changes, and most users of
regex-automatashould be ableto move to
0.4from0.3without any changes at all.regex-syntaxbreaking change release:This release also includes a
regex-syntax 0.8.0breaking change release,which, like
regex-automata, was necessary in order to support the new wordboundary assertions. This release also includes some changes to the
Asttype to reduce heap usage in some cases. If you are using the
Asttypedirectly, your code may require some minor modifications. Otherwise, users of
regex-syntax 0.7should be able to migrate to0.8without any code changes.regex-literelease:The
regex-lite 0.1.1release contains support for the new word boundaryassertions. There are no breaking changes.
