Parsing function arguments

[glenlow]

Apologies in advance if this is too newbie-ish. Couldn't find the
answer via googling or looking at various FAQ's.

Given a C function call in a string, how do I parse out the individual
arguments?

E.g.

"... func ((a+b)/c,d,e,f+(g+(h,i))) ..."

I need to get an array that is

("(a+b)/c","d","e","f+(g+(h,i))")

I know I can use extract_bracketed to get the outermost set of braces,
but how to I split out the arguments therein? (Note I can't just use
split on the comma since one of the comma's is embedded in a bracket
expression.

Try taking a look at
perldoc -q delimited
"How can I split a [character] delimited string except when inside
[character]? (Comma-separated files)"

That generally deals with the case in which a CSV line has commas
embedded in quoted fields, but you should be able to modify the
solution (or use one of the two recommended modules) for your problem
as well...
