devkit-codegen-test

Codegen pipeline integration tests for the dsviper DevKit.

Two projects exercise the DSM → Kibo → templates → runtime pipeline:

• features/ — value-system features: data, stream, json, database, attachments, codecs, hashers, fuzz.
• service/ — RPC / function-pool features: function pools, attachments pools, remote variants, bridges.

These projects are not built or run by the dsviper runtime CI. They serve as a manual sanity check of the codegen pipeline and as a reference of how a downstream application wires DSM definitions, Kibo, templates, and the runtime together.

Layout assumption

This repo expects three sibling checkouts under a common parent directory:

<common parent>/
├── com.digitalsubstrate.viper/         # runtime + third_parties (C++ ; private)
├── kibo/                               # Kibo jar (built via `mvn package`)
├── kibo-template-viper/                # Kibo templates (cpp/, python/)
└── devkit-codegen-test/                # this repo

The siblings live in their own repositories:

• viper — the Viper C++ runtime. Sources are not publicly distributed (Digital Substrate Commercial License 1.2); the public artefact is the dsviper wheel on PyPI. The full C++ build below therefore requires access to the runtime sources (Digital Substrate organisation members or licensed evaluation). The Python-only flow (features/python) is exercisable against an installed dsviper wheel without source access.
• digital-substrate/kibo — code generator.
• digital-substrate/kibo-template-viper — first-party Kibo templates for the Viper ecosystem.

generate.py resolves Kibo and templates via:

1. KIBO_JAR and KIBO_TEMPLATES environment variables, if set.
2. Otherwise, ../kibo/target/kibo-*.jar and ../kibo-template-viper/.

CMakeLists.txt (via lib.cmake) locates the sibling com.digitalsubstrate.viper/ checkout to build the third_parties (sqlite, json, hash, antlr4, cli11) and the viper static target.

Usage

# 1. Generate C++ and Python code from the DSM definitions.
cd features
python3 generate.py all.dsm -c -p
cd ../service
python3 generate.py -c -p

# 2. Build the C++ executables (links viper from the sibling checkout).
cd ..
mkdir build && cd build
cmake ..
cmake --build . -j

# 3. Run the Python tests against the generated `features` package.
cd ../features/python
./run_test.sh

CMakeLists.txt skips features/ or service/ cleanly when their generated content is missing, so a fresh clone configures without errors.
