Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add support for extension modules This adds support for an [extensions] section to hgrc. This has the form of: [extensions] mod=[path] If a path is specified, the python module found at that path is load. Otherwise, __import__ is used to find the module. Each module must implement a dict called cmdtable where the command line options for that module live. Each module must also implement a reposetup function: cmdtable = {} def reposetup(ui, repo): pass Index: hg/mercurial/ui.py ===================================================================
