The ZMQ_PubSub_Categ Module
|
|
============================
|
|
|
|
This module is consuming the Redis-list created by the ZMQ_PubSub_Tokenize_Q
|
|
Module.
|
|
|
|
Each words files created under /files/ are representing categories.
|
|
This modules take these files and compare them to
|
|
the stream of data given by the ZMQ_PubSub_Tokenize_Q Module.
|
|
|
|
When a word from a paste match one or more of these words file, the filename of
|
|
the paste is published/forwarded to the next modules.
|
|
|
|
Each category (each files) are representing a dynamic channel.
|
|
This mean that if you create 1000 files under /files/ you'll have 1000 channels
|
|
where every time there is a matching word to a category, the paste containing
|
|
this word will be pushed to this specific channel.
|
|
|
|
..note:: The channel will have the name of the file created.
|
|
|
|
Implementing modules can start here, create your own category file,
|
|
and then create your own module to treat the specific paste matching this
|
|
category.
|
|
|
|
..note:: Module ZMQ_Something_Q and ZMQ_Something are closely bound, always put
|
|
the same Subscriber name in both of them.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
*Need running Redis instances. (Redis)
|
|
*Categories files of words in /files/ need to be created
|
|
*Need the ZMQ_PubSub_Tokenize_Q Module running to be able to work properly.
