Static Analysis and Source Code Manipulation in TypeScript
summary
Uses the TypeScript compiler API to parse source with createSourceFile and then runs concrete scripts: a checker that lists class declarations with an extends clause, a refactor that renames classes to snake_case across thousands of files using a TS simple ast wrapper that edits text and calls the language service rename, and a generator that inserts 150 method overloads into declaration files. The refactor updates identifiers and module specifiers, saves transactionally, and demonstrates the AST viewer at TS AST Viacom.
