摘要

Described are techniques for obtaining grammar updates. A grammar service receives a notification regarding a grammar update applied to a target. The grammar update is an update to a command syntax used by said target. The grammar service sends an update request to said target to obtain said grammar update. The target sends to the grammar service an update response including said grammar update. Also described are techniques for processing a command line. One of a plurality of rule sets is selected. The command line is parsed at said client using said selected rule set. If parsing did not result in a syntax error, a command request is sent from said client to said target. In response, the client receives a command response including information regarding a version of syntax rules currently used on said target.
