haira-compiler

The Haira compiler pipeline processes source code sequentially through the lexer, parser, resolver, checker, and codegen stages. Each phase transforms the input to enable multi-file resolution and prepare it for agentic runtime integration.

To implement new syntax in the Haira compiler, you modify the lexer to tokenize the new tokens and update the parser to construct the corresponding syntax tree. This requires understanding the compilation pipeline to ensure changes pass the checker and codegen stages successfully.

Debugging Haira compiler codegen and runtime integration issues involves tracing the output through the resolver and checker phases. You identify where the compilation pipeline fails to properly translate the syntax tree for the agentic runtime, then apply targeted fixes to the code generation logic.

Yes, the Haira compiler internals allow you to improve type checking by modifying the checker phase and extending the resolver for multi-file resolution. Understanding the compilation pipeline lets you refine how types are validated across files before code generation.

Contributing to the Haira runtime and codegen requires advanced understanding of compiler architecture, specifically how lexers, parsers, and code generators interact. Familiarity with language processing pipelines is necessary to effectively debug and extend the compiler's feature set.
