Pass conky object to external script

Question

I have a conky object, and I want to pass it as parameter of a bash / lua script. How do I do it?

Example:

conky object: ${tcp_portmon 1 61000 lport 0} i.e the port of the first tcp connection

script: $ lsof -i :<PORT> | sed -n 2p | awk '{print $1}' i.e finds the process with that port

What I tried (unsuccessfully):

• ${exec lsof -i :${tcp_portmon 1 61000 lport 0} | sed -n 2p | awk '{print $1}'}
• ${exec echo $(lsof -i :${tcp_portmon 1 61000 lport 0} | sed -n 2p | awk '{print $1}')}
• ${lua conky_proc_port ${tcp_portmon 1 61000 lport 0}}, where conky_proc_port simply outputs the parameter

How do I do it?

Answer 1

The best way to pass the conky object to a lua function is... by not passing the object.

Instead, use the lua API function conky_parse within the lua function to evaluate the string '${tcp_portmon 1 61000 lport 0}' and then process the result as desired.

Alternativly, rather than hardcoding the string, you could pass the string '${tcp_portmon 1 61000 lport 0}' to the lua function and then use conky_parse on the passed string.

See the "LUA API" section of man conky for more info.
