What's the fastest way to parse strings in C#? Currently I'm just using string indexing (string[index]) and the code runs reasonably, but I can't help but think that the continuous range checking that the index accessor does must be adding something. So, I'm wondering what techniques I should consider to give it a boost. These are m...

What I want to do is read in the JS file server side and parse out all the method names of only the methods that have that certain signature. Let's say my JS file looked like below: fu...

I know something about regular expressions, parse trees and abstract syntax trees.

So far I have this (not handling re...
I have a huge grammar developed for pyparsing as part of a large, pure python application. I have reached the limit of performance tweaking and I'm at the point where the diminishing returns make me start to look elsewhere. Yes, I think I know most of the tips and tricks and I've profiled my grammar and my application to dust. What next...
Hello What is the best way to instantiate a new Color from any supported value, like for example "FF00FF11" or "Gray" or "234,255,65"? I need to generalize maximum as possible this implementation, but can't find a way to do it. With System.Reflaction I can get the value for enumerator KnownColor, but how can I distinct this "FF00FF11"...

I'm trying to parse out some log files with ruby. I have plenty of experience with regexes but the other day I was using rails routes and thought that might be a really neat way to parse out these log files because it would be incredibly easy to understand the parser.
