There isn't a way to get the stderr, but you can have the exit code returned by passing

"exit-status" as an optional parameter. This will return a list of two items: the stdout and

the error code

 

local result = [ SHELL path/to/tool.py : strip-eol exit-status ] ;

local output = $(result[1]) ;

local status = $(result[2]) ;

 

This option is documented here:
