jp (pubsub): new search command: search is a kind of "grep for Pubsub". It's a powerful command which allows to look for specific data in a pubsub node, recurse sub nodes if requested, and execute an action on the result. search allows to look for items with following filter: - simple text search - regex - xpath - python code filters are read an applied in the order in which they appear on the command line. Then flags can be used to modify behaviour, currently there are: - ignore-case to specify if search must be case sensitive or not - invert to invert result of the search (i.e. don't match instead of match) - dot-all which is specific for regex, cf. re module - only-matching which return the matching part instead of the full item Once a item match filters, an action is applied to it, currenlty there are: - print, which do a simple output of the full item (default) - exec, which run a jp command, specifying the service, node and item corresponding to the match - exteral, which run a external command, sending the full item on stdin By default search is only done on requested node, but if max-depth is more than 0, sub nodes will be searched too.
