The zero-width assertions \` \' \b \B were parsed in a sloppy way so that a following postfix repetition operator could yield surprising results. For instance, "\\b*" would act as "\\b\\*", and "xy\\b*" would act as "\\(?:xy\\b\\)*". Except for \` and ^, any following postfix operator now applies to the zero-width assertion itself only, which is predictable and consistent with other assertions, if useless in practice. For historical compatibility, an operator character following \` and ^ always becomes a literal. (Bug#64128) * src/regex-emacs.c (regex_compile): Set `laststart` appropriately for each zero-width assertion instead of leaving it with whatever value it had before. Remove a redundant condition. * test/src/regex-emacs-tests.el (regexp-tests-zero-width-assertion-repetition): New test. * doc/lispref/searching.texi (Regexp Special): Say that repetition operators are not special after \`, and that they work as expected after other backslash escapes. * etc/NEWS: Announce. |
