[erlang-questions] String to proplist

[Bengt Kleberg]

greetings,

a naive version (to get you started :-) is:
proplist_from_options( Options ) ->
	Props = string:tokens( Options, ", " ), % should give you ["abc=12343", 
"someThing=value"]
	Fun = fun (Prop) -> [Name,Value] = string:tokens( Prop, "=" ), 
{erlang:list_to_atom( Name ),Value} end,
	lists:map( Fun, Props ).


expand on this by considering erlang:list_to_existing_atom/1 and if 
Props might contain empty ("") strings, too. Etc, etc
