Hi there,
I just added a new, probably handy function to the evaluator:
decode(index, ...)
it takes a variable number of parameters, at least 2. the first one is
interpreted as an index, and the function returns the n'th parameter.
some examples:
decode(-1,'a','b') => '' (empty)
decode(0,'a','b') => 'a'
decode(1,'a','b') => 'b'
decode(2,'a','b') => '' (empty)
decode(3, 'a','b','c','d','e','f') => 'd'
It may be used to reduce nested '?' operators
I've got two questions here:
- is 'decode' the right name for it (there's a similar function in
Oracle's PL/SQL)
- is 'plugin_math' the right place for it?
enjoy, Michael
