comparison mercurial/revset.py @ 16820:20f55613fb2a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: add pattern matching to 'tag' revset expression If the string provided to the 'tag' predicate starts with 're:', the rest of the string will be treated as a regular expression and matched against all tags in the repository. There is a slight backwards-compatibility problem for people who actually have tags that start with 're:'. As a workaround, these tags can be matched using a 'literal:' prefix. If no tags match the pattern, an error is raised. This matches the behaviour of the previous exact-match code.
