Re: [mosquitto-dev] Requesting for mosquitto version which supports payl

[Nicholas Humfrey <njh@xxxxxxxxxx>]

Hello,

I agree with Adrian - it is not quite clear what you are trying to 
achieve.
Do you mean a 'binary' (non-text) payload?
mosquitto_sub supports binary payloads, it is just that there is no way 
of knowing when one message payload ends and the next begins - unless 
you can be sure the messages don't contain newline characters.


Did I imagine that there was a version of mosquitto_sub that supports a 
'-1' option to receive a single message and then exit? That may help 
with a binary message payload.

I wonder if it would be useful to be able to pass an '--exec' command 
line argument to mosquito_sub - which runs the specified command for 
each message received - with the message written to STDIN.
