Codegen Language Reference

The complete language reference. This is the place to start if you want to learn how to write Codegen programs. It covers:

• Program structure, pragmas, and comments
• Data types — scalars, optionals, lists, maps, tuples, and user-defined types
• Variable declarations and modifiers
• Operators — arithmetic, comparison, logical, bitwise, string, and regex
• Output, control flow, and loops
• Functions, classes, and enumerations
• Exception handling and conditional compilation
• Built-in functions and passthrough code

Codegen Functions Reference

A detailed reference for the built-in functions available in Codegen, generated from the code generator's function metadata. For each function it documents the arguments, return value, and a short description. Functions are grouped by category, including:

• Program & runtime, math, and random numbers
• Type casts and number/string conversion
• String formatting, inspection, and transformation
• Regular expressions and character classification
• Console, stream, and file I/O
• Lists, maps, tuples, and enums
• Copying, references, optionals, and atomics

It also explains the type notation (<int>, [list], {map}, «tuple», ≤enum≥, etc.) used throughout the language.
