comparison mercurial/revset.py @ 34854:39b094e4ae2c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: extract a parsefollowlinespattern helper function We'll need the same logic in forthcoming changeset to handle --line-range option in 'hg log' command. The function lives in scmutil.py (rather than util.py) as it uses match and pathutil modules.
