* bpo-30688: Support \N{name} escapes in re patterns. (GH-5588)Serhiy Storchaka2018-02-101-0/+36
| | | Co-authored-by: Jonathan Eunice <jonathan.eunice@gmail.com>
* bpo-32308: Replace empty matches adjacent to a previous non-empty match in ↵Serhiy Storchaka2018-01-041-14/+9
| | | | re.sub(). (#4846)
* Fix improper use of re.escape() in tests. (#4814)Serhiy Storchaka2017-12-121-1/+1
|
* bpo-25054, bpo-1647489: Added support of splitting on zerowidth patterns. ↵Serhiy Storchaka2017-12-041-13/+31
| | | | | | (#4471) Also fixed searching patterns that could match an empty string.

* bpo-30397: Add re.Pattern and re.Match. (#1646)Serhiy Storchaka2017-10-041-2/+2

* bpo-30978: str.format_map() now passes key lookup exceptions through. (#2790)Serhiy Storchaka2017-08-031-1/+1
| | | Previously any exception was replaced with a KeyError exception.
* bpo-30605: Fix compiling binary regexs with BytesWarnings enabled. (#2016)Roy Williams2017-06-101-2/+14
| | | | Running our unit tests with `-bb` enabled triggered this failure.
* bpo-30375: Correct the stacklevel of regex compiling warnings. (#1595)Serhiy Storchaka2017-05-161-3/+14
| | | | | | Warnings emitted when compile a regular expression now always point to the line in the user code. Previously they could point into inners of the re module if emitted from inside of groups or conditionals.
* bpo-30299: Display a bytecode when compile a regex in debug mode. (#1491)Serhiy Storchaka2017-05-141-0/+27
| | | | | `re.compile(..., re.DEBUG)` now displays the compiled bytecode in human readable form.
* bpo-30340: Enhanced regular expressions optimization. (#1542)Serhiy Storchaka2017-05-141-14/+12
| | | | This increased the performance of matching some patterns up to 25 times.
* bpo-30298: Weaken the condition of deprecation warnings for inline ↵Serhiy Storchaka2017-05-101-14/+45
| | | | | | | | modifiers. (#1490) Now allowed several subsequential inline modifiers at the start of the pattern (e.g. '(?i)(?s)...'). In verbose mode whitespaces and comments now are allowed before and between inline modifiers (e.g. '(?x) (?i) (?s)...').
* bpo-30285: Optimize case-insensitive matching and searching (#1482)Serhiy Storchaka2017-05-091-0/+9
| | | | of regular expressions.
* bpo-30277: Replace _sre.getlower() with _sre.ascii_tolower() and ↵Serhiy Storchaka2017-05-051-10/+16
| | | | _sre.unicode_tolower(). (#1468)
* bpo-30215: Make re.compile() locale agnostic. (#1361)Serhiy Storchaka2017-05-051-0/+32
| | | | | | Compiled regular expression objects with the re.LOCALE flag no longer depend on the locale at compile time. Only the locale at matching time affects the result of matching.
* bpo-10076: Compiled regular expression and match objects now are copyable. ↵Serhiy Storchaka2017-04-161-0/+9
| | | | (#1000)
* bpo-29995: re.escape() now escapes only special characters. (#1007)Serhiy Storchaka2017-04-131-18/+19
|
* bpo-29919: Remove unused imports found by pyflakes (#137)Victor Stinner2017-03-271-2/+2
| | | Make also minor PEP8 coding style fixes on modified imports.
* Revert "bpo-29571: Use correct locale encoding in test_re (#149)" (#554)Benjamin Peterson2017-03-071-1/+1
| | | This reverts commit ace5c0fdd9b962e6e886c29dbcea72c53f051dc4.

* bpo-29571: Use correct locale encoding in test_re (#149)Nick Coghlan2017-02-181-1/+1
| | | | | | | ``local.getlocale(locale.LC_CTYPE)`` and ``locale.getpreferredencoding(False)`` may give different answers in some cases (such as the ``en_IN`` locale). ``re.LOCALE`` uses the latter, so update the test case to match.
