Text (SMS) message parser with configurable template

[francois]

The goal of this task is to create a method whereby the Kannel/SMS request input plug-in can parse incoming messages based on a message structure template which could be used to specify message formats, channels to use, etc.

This template will be configurable via the Kannel/SMS request input config file.

This functionality is required for #5 (with added flexibility) and #9.

Details

For instance, a structure template such as the following:

[%c:]%m

would be parsed as follows:

• If the plug-in sees a : (colon) character in the message, everything before it is interpreted as the channel to be used (e.g. MMS)
• Whatever follows after the : will be used as the actual request data
• If no : is present, simply use the entire message as the request data (this is how the system currently uses SMS messages)

So, if using the above template, a message such as MMS:Cat would cause the system to search for the Cat article and transmit it using the MMS channel. A message such as Cat would cause the system to search for the Cat article, and transmit it using the default (pre-configured) channel(s).
