comparison mercurial/revset.py @ 24518:dd5e56f08d13

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: add hook after tree parsing This will be useful to execute actions after the tree is parsed and before the revset returns a match. Finding symbols in the parse tree will later allow hashes of hidden revisions to work on the command line without the --hidden flag.
