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.
