Support extensions using dorecord, e.g. crecord Provide extendable keyword.recordextensions variable, so other extensions beside hgext.record which provide the dorecord function can cooperate with hgext.keyword like so (example from crecord): def extsetup(): try: keyword = extensions.find('keyword') keyword.restricted += ' crecord qcrecord' try: # use record support in keyword.py if present keyword.recordcommands += ' crecord qcrecord' keyword.recordextensions += ' crecord' except AttributeError: pass except KeyError: pass
