I know this question is 5 years old, but contrary to what everyone else has said, i have actually concocted a quite effective pattern for doing as you have asked. Albeit, quite complex, I have used this several times in my own projects and I've yet to have a hiccup... wish I had seen this question much sooner. Hope this helps (If not for you, hopefully for those who are searching for a similar solution)

function\s*([A-z0-9]+)?\s*\((?:[^)(]+|\((?:[^)(]+|\([^)(]*\))*\))*\)\s*\{(?:[^}{]+|\{(?:[^}{]+|\{[^}{]*\})*\})*\}
