"""Generate an output from one or several input and a template.
Take "input-list" buildout parameter as input.
Each input of the list is separated by
\
n
Each input contains :
1/ The parameter to use (like mybuildoutpart:myparameter)
2/ The name of the input to use as key.
If all parameters in input are found, create an "output" parameter from a
"template" parameter. The "template" parameter is just a string containing
python parameters (like %(mykey)s).
Will produce nothing if one element of "input_list" doesn't exist.
Will raise if any input reference non-existent buildout part.
Example :
[get-output]
recipe = slapos.cookbook:generate_output_if_input_not_null
input-list =
firstkey mybuildoutpart:myparameter
otherkey myotherbuildoutpart:myotherparameter
template = I want to get %(key)s and %(otherkey)s
This example will produce an "output" parameter if myparameter and
myotherparameter are defined.
