This Simple Algorithm Powers Real Interpreters: Pratt Parsing

The post explains the Pratt parsing algorithm, a powerful technique for manual expression parsing in programming. It details the process of converting a sequence of tokens into a tree representation, which is crucial for implementing interpreters. The example uses Rust for creating a lexer and handling infix expressions with operators like addition, multiplication, and more. The method focuses on binding power to determine operator precedence and utilizes recursion for efficient parsing. The algorithm handles expressions with parenthesis, function chaining, and assignment statements, laying foundations for basic interpreters or compilers.
