2. Writing a programming language - the Parser

This series is about how to write a programming language. A parser takes in the simple list of "tokens" from the lexer (see last video) and builds them up into a tree structure, ready to be understood by the evaluator (see next video!). Andy Balaam walks through the parser of Cell, a little programming language he wrote.
