Bundle the HoloHub Module template - #224
Conversation
Copy modules/template verbatim from nvidia-holoscan/holohub at 367167cb94e8597235d369ff0b47a6a907786a43. Keep the source snapshot unmodified so CLI-specific adaptations remain independently reviewable. Co-authored-by: Codex <noreply@openai.com> Signed-off-by: Wenqi Li <wenqil@nvidia.com>
Record the upstream snapshot, keep the verbatim generated tree outside repository formatters, and assert that key template assets reach built wheels. This does not change holoscan create template selection. Co-authored-by: Codex <noreply@openai.com> Signed-off-by: Wenqi Li <wenqil@nvidia.com>

WalkthroughThe change adds a packaged Cookiecutter template for Holoscan modules. It includes generation hooks, Python and C++ operators and applications, CMake and package configuration, CI workflows, tests, documentation, and installed-package resource checks. ChangesHoloscan module template
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The bundled module template can currently generate projects with invalid metadata, incomplete CMake dependency configuration, broken standalone checks, or inconsistent license content. These issues could cause downstream module builds, tests, or validation to fail, so the PR needs owner follow-up or explicit acceptance before merge. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

- Around line 66-71: Update both local Python hooks in the pre-commit
configuration, including holoscan-metadata-validate and lint.py, to invoke the
interpreter from HOLOSCAN_CLI_PYTHON_BIN instead of hardcoded python3,
preserving their existing arguments and behavior.
- Around line 82-92: Update post_gen_project.py and the check-copyright hook so
standalone generation never leaves an entrypoint pointing to a missing script.
Bundle the required copyright scripts when available; otherwise disable or
remove the check-copyright hook from the generated pre-commit configuration.
In
`@src/holoscan_cli/templates/module/`{{cookiecutter.module_repo_name}}/metadata.json:
- Line 26: Update the operator_names value in metadata.json to use the existing
PascalCase Jinja expression from the operator source templates, so it emits the
generated class name such as MySensorOp instead of the lowercase operator slug.
In
`@src/holoscan_cli/templates/module/`{{cookiecutter.module_repo_name}}/operators/{{cookiecutter.operator_slug}}/CMakeLists.txt:
- Around line 7-11: Update the generated operator target’s target_link_libraries
declaration to link holoscan::core as PUBLIC, and modify the generated
Config.cmake template to call find_dependency(holoscan REQUIRED COMPONENTS core)
before including exported targets.
In
`@src/holoscan_cli/templates/module/`{{cookiecutter.module_repo_name}}/tests/python/test_{{cookiecutter.operator_slug}}.py:
- Line 19: Add pytest>=8.2 as a test dependency in the generated pyproject.toml
and ensure the CI setup installs the project’s test dependencies, so the
generated test using pytest.importorskip with exc_type is supported.
In `@src/holoscan_cli/templates/module/cookiecutter.json`:
- Around line 3-8: Validate template inputs before rendering, including
restricting language to cpp or python and enforcing the documented naming
conventions for project_name, module_slug, module_repo_name, and operator_slug.
Apply validation to all context sources, including --context, and reject invalid
values before generating files so package imports, paths, namespaces, and CMake
identifiers remain valid.

Thanks @wyli ! LGTM, I did not review in detail and assume the cookiecutter template files were copied migrated from HoloHub, please let me know if there's anywhere in particular you'd like me to revisit
Will the experience following this integration still be ./holohub create <module_name> --template path/to/template, without Holoscan CLI checking any default bundled templates yet? More work to do to get to ./holohub create <module_name>?
this is a simple PR copy the template from HoloHub verbatim (82734e7) and very minor config (78bcc09), the follow up PR (#225) should address your comments. |
