I have been programming for a few years now and have seen the name Bison in passing, but never bothered to ask why it is or why it might be needed. How can Bison effect how I program, can it make my C/C++ code faster?
Bison is a parser generator. It takes it’s input in something similar to Backus-Naur notation and outputs code to parse input according to that grammar. It lets you write a parser more easily than you would otherwise. Instead of having to do everything manually, you only have to specify the rules of your grammar and what you want to happen when it matches one of the rules.
