Release Notes
rust-lang/regex
v1.8.1
==================
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:
Fix a bug where a word boundary could interact with prefix literal
optimizations and lead to a false positive match.
v1.8.0
==================
This is a sizeable release that will be soon followed by another sizeable
release. Both of them will combined close over 40 existing issues and PRs.
This first release, despite its size, essentially represent preparatory work
for the second release, which will be even bigger. Namely, this release:
aho-corasick
to the recently release 1.0version.
regex-syntax
to the simultaneously released0.7
version. The changes toregex-syntax
principally revolve around arewrite of its literal extraction code and a number of simplifications and
optimizations to its high-level intermediate representation (HIR).
The second release, which will follow ~shortly after the release above, will
contain a soup-to-nuts rewrite of every regex engine. This will be done by
bringing
regex-automata
intothis repository, and then changing the
regex
crate to be nothing but an APIshim layer on top of
regex-automata
's API.These tandem releases are the culmination of about 3
years of on-and-off work that began in earnest in March
2020.
Because of the scale of changes involved in these releases, I would love to
hear about your experience. Especially if you notice undocumented changes in
behavior or performance changes (positive or negative).
Most changes in the first release are listed below. For more details, please
see the commit log, which reflects a linear and decently documented history
of all changes.
New features:
Permit many more characters to be escaped, even if they have no significance.
More specifically, any ASCII character except for
[0-9A-Za-z<>]
can now beescaped. Also, a new routine,
is_escapeable_character
, has been added toregex-syntax
to query whether a character is escapeable or not.Add
Regex::captures_at
. This filles a hole in the API, but doesn't otherwiseintroduce any new expressive power.
Capture group names are now Unicode-aware. They can now begin with either a
_
or any "alphabetic" codepoint. After the first codepoint, subsequent codepoints
can be any sequence of alpha-numeric codepoints, along with
_
,.
,[
and]
. Note that replacement syntax has not changed.Add
Match::is_empty
andMatch::len
APIs.Add an
impl Default for RegexSet
, with the default being the empty set.A new method,
Regex::static_captures_len
, has been added which returns thenumber of capture groups in the pattern if and only if every possible match
always contains the same number of matching groups.
Named captures can now be written as
(?<name>re)
in addition to(?P<name>re)
.regex-syntax
now supports empty character classes.regex-syntax
now has an optionalstd
feature. (This will cometo
regex
in the second release.)Hir
type inregex-syntax
has had a number of simplificationsmade to it.
regex-syntax
has support for a newR
flag for enabling CRLFmode. This will be supported in
regex
proper in the second release.regex-syntax
now has proper support for "regex that nevermatches" via
Hir::fail()
.hir::literal
module ofregex-syntax
has been completelyre-worked. It now has more documentation, examples and advice.
allow_invalid_utf8
option inregex-syntax
has been renamedto
utf8
, and the meaning of the boolean has been flipped.Performance improvements:
aho-corasick 1.0
may improve performance in somecases. It's difficult to characterize exactly which patterns this might impact,
but if there are a small number of longish (>= 4 bytes) prefix literals, then
it might be faster than before.
Bug fixes:
Improve
Debug
impl forMatch
so that it doesn't show the entire haystack.#731:
Fix a number of issues with printing
Hir
values as regex patterns.Add explicit example of
foo|bar
in the regex syntax docs.Clarify that
SetMatches::len
does not (regretably) refer to the number ofmatches in the set.
Clarify "verbose mode" in regex syntax documentation.
#950:
Fix
CaptureLocations::get
so that it never panics.Clarify documentation for
Regex::shortest_match
.Fix
\p{Sc}
so that it is equivalent to\p{Currency_Symbol}
.Add more clarifying documentation to the
CompiledTooBig
error variant.Clarify that
regex::Regex
searches as if the haystack is a sequence ofUnicode scalar values.
Replace
__Nonexhaustive
variants with#[non_exhaustive]
attribute.Optimize case folding since it can get quite slow in some pathological cases.
Reject
(?-u:\W)
inregex::Regex
APIs.Add a missing
void
keyword to indicate "no parameters" in C API.Fix
\p{Lc}
so that it is equivalent to\p{Cased_Letter}
.Clarify documentation for
\pX
syntax.Configuration
