# phabricator.py - simple Phabricator integration # # Copyright 2017 Facebook, Inc. # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. """simple Phabricator integration (EXPERIMENTAL) This extension provides a ``phabsend`` command which sends a stack of changesets to Phabricator, and a ``phabread`` command which prints a stack of revisions in a format suitable for :hg:`import`, and a ``phabupdate`` command to update statuses in batch. A "phabstatus" view for :hg:`show` is also provided; it displays status information of Phabricator differentials associated with unfinished changesets. By default, Phabricator requires ``Test Plan`` which might prevent some changeset from being sent. The requirement could be disabled by changing ``differential.require-test-plan-field`` config server side. Config:: [phabricator] # Phabricator URL url = https://phab.example.com/ # Repo callsign.
