Hey guys,

I am working on a small plug-in which stores settings in a yaml file,  
e.g.:

* * *

:before: var lastsel2;  
:params:  
:url: [http://www.google.com](http://www.google.com)  
:datatype: xml  
:mtype: GET

etc., then later turning them into js with something like

params.each do |key,value|  
emit "#{key}: #{value.to\_json}  
end

so far so good. My question is, what should I put in the place of ???

:params:  
:some\_func: ???

so that the Ruby code above spits out this:

some\_func: function(id) {  
do\_some\_stuff  
do\_something\_else  
}

I hope it’s clear 🙂 Obviously I’d like to store the function params  
and body as well.  
Is there a (semi-)standard way of doing this? I thought of  
representing the js function with some custom class, storing the param  
list and body as strings. Am I completely off?

Cheers,  
Peter
