A mqtt subscriber-client that lets you to save/organize your data messages into filesystem directory.
This helps in organizing your subscribed data in neat hierarchy.
mqtt-dirpub is based on original sub_client.c that comes with mosquitto.
--fmask <file-mask>
file-mask - path to message outfile.
allowed masks are:
@[epoch|date|year|month|day|datetime|hour|min|sec|id|topic[1-9]]
eg.
--fmask '/tmp/msgs/@year/@month@-@day/@topic/@hour@min'
will create file:
/tmp/msgs/2010/10-29/topic/0540
Note: topic/s having hierarchy structure gets further resolved to directory.
--overwrite
Works only with --fmask. This option starts client in overwrite mode.
Caution: The existing data files get overwritten with every messages received.
--nodesuffix
Works only with --fmask. This option provides file suffix for leaf/text nodes.

Your can also drop/replace sub_client.c file in mosquitto-<ver>/client/ directory
to compile with parent package.
