Code Parsing

Code parsing is the process of analyzing source code to understand its structure and meaning, typically by breaking it down into tokens and building an abstract syntax tree (AST). It is a fundamental technique used in compilers, interpreters, linters, and code analysis tools to enable tasks like syntax validation, transformation, and static analysis. This concept underpins many developer tools that interact with or manipulate code programmatically.

Also known as: Parsing, Source Code Parsing, Syntax Analysis, AST Generation, Lexical Analysis

Why learn Code Parsing?

Developers should learn code parsing when building tools that require automated code understanding, such as custom linters, code formatters, refactoring tools, or domain-specific language (DSL) processors. It is essential for tasks like syntax highlighting in editors, code generation, and security analysis to detect vulnerabilities. Mastery of parsing techniques allows developers to create robust software that can interpret and transform code reliably across different programming languages.
