This repository provides a Python library for creating, reading, and writing AUTOSAR XML (ARXML) files, targeting Classic AUTOSAR platforms from R19-11 to R22-11. It covers a broad range of AUTOSAR elements—software components, port interfaces, data types, constants, compu methods, service needs, and more—through an object-oriented model with full XML serialization. The library is not an end-user application but a tool for automotive engineers and tool integrators to programmatically generate ARXML artifacts for import into commercial AUTOSAR toolchains. It also includes an early-stage code generator that produces C type definitions (Rte_Type.h) from the XML model. The architecture follows a layered design: an XML model layer (autosar.xml) with element classes, enums, and references; a workspace abstraction that manages packages, documents, and template application; and a generator layer that transforms the XML model into an intermediate representation for code generation. A notable design pattern is the template system (ElementTemplate/GenericTemplate) that decouples high-level element recipes from their serialization, enabling config-driven generation of entire projects from TOML configuration files. The library is supported by a comprehensive test suite that exercises round-trip XML serialization for hundreds of element types. The codebase shows good craftsmanship—clean separation of concerns, consistent use of base classes (Identifiable, Describable), version-aware enum handling, and typed reference system. However, it is still in development (v0.5.7) with many planned releases and a roadmap that implies future breaking changes. Several AUTOSAR elements remain unimplemented, and the test suite relies on exact XML string comparisons, making it brittle. The project is maintained by a single contributor with no PyPI release, posing adoption and continuity risks. Overall, it is a solid, functional library for its domain but not yet production-ready for all use cases.
