Per the README contract, an object schema without an explicit
`additionalProperties` was documented as rejected at generation time,
but the code defaulted it to `false` and silently generated a strict
parser that rejects valid documents with extra properties.
Make the code match the documented contract by raising GenError when
`additionalProperties` is absent, with a clear message instructing the
author to set it explicitly to false. Update the README prose section
to list absent additionalProperties alongside true, and fix existing
schemas and tests to declare additionalProperties explicitly.
Closes#55
Following review feedback, the generator no longer supports permissive
objects. Changes:
- Reject `additionalProperties: true` at generation time.
- Treat an absent `additionalProperties` as `false`, so every object is
strict by default and unknown keys are rejected during parsing.
- Remove the now-dead permissive-object infrastructure: `Kind::Skip`,
`Cat::Skip`, `kSkip`, the per-frame `unknown` key set, and `isStrict()`.
- Update the README feature/rejection tables accordingly.
- Remove the permissive "loose" object from example.schema.json and the
associated tests from test_gen.cpp.
- Add Python unit tests verifying the new `additionalProperties` behavior.
All tests pass (`ctest --output-on-failure`).
Remove the standalone "Run schemagen tests" workflow step and instead
add the big-schema regression test to contrib/schemagen/CMakeLists.txt
so ctest picks it up alongside schemagen_example. Update README to
document both `ctest` and the convenience `./run_tests.sh`.
Closes#3
Replace the 32-bit `uint32_t seen` bitmask with a `std::vector<uint64_t>`
bitset sized to the actual field count. `requiredMask` is now a vector of
the same word count, and required-field checks use per-word masking so that
optional fields do not cause false rejections.
Adds big.schema.json + test_big.cpp regression tests covering the issue
reproducer (40 required properties, missing/duplicate at index 32), plus
run_tests.sh to exercise both test_gen.cpp and test_big.cpp.
Fixes#3
Generates a C++ type and a streaming builder parser from a JSON Schema,
built on weaseljson. The builder copies incoming bytes directly into their
final destinations in the result struct (no intermediate DOM) and hands
back ownership via take() once parsing completes.
Supports objects/structs, required vs optional (std::optional) fields,
nullable types, string enums, arrays, $ref including recursion (broken
with unique_ptr), and additionalProperties (strict reject or skip).
Unsupported schema constructs are rejected at generation time; schema
violations are rejected at parse time.
