sample_cpp_models_generator

Minimal example generator: turns OpenAPI schemas into plain C++ structs (and array schemas into std::vector<...> aliases). Mainly useful as a small, readable reference when writing or debugging a generator (see docs/javascript-api.md for the engine's built-in functions/globals this generator uses: kindOf, nameOf, renderTemplate).

Usage

openapi-yagen g -o out -g sample_cpp_models_generator/src \
    -c openapi.yaml -v "namespace=MyModels"

Variable	Required	Description
namespace	no	C++ namespace to wrap the generated structs in

Output layout

model.h   one header with one struct per object schema, one `using` alias per array schema

Known limitations

• Only object (→ struct) and array (→ using X = std::vector<...>) top-level schemas are handled; other schema shapes (enum, oneOf/anyOf, allOf, plain scalars) are silently skipped.
• Only primitive scalar property types are mapped (see lib.js's mapType); no nested object/array properties, no $ref resolution beyond what the engine already resolves.
• No validation/constraints are emitted.
• Generated files are not run through a formatter by default - see run.sh for an example wiring clang-format via -p.

Try it

From the generators/ directory, with openapi-yagen on PATH:

cd generators && ./run.sh

generates into generators/out from test/resources/petstore.yaml.

There is no test/ subdirectory for this generator yet - see generators/README.md for the README.md/src//test/ convention this generator should eventually adopt too.
