## Summary - **CMake-based CDB generation for module tests**: Replace hand-written compile_commands.json with CMakeLists.txt (CMake 3.28 `FILE_SET CXX_MODULES`) in all 26 `tests/data/modules/*/` directories. CDB is generated on-the-fly via `cmake -G Ninja` during test setup. - **`@pytest.mark.workspace()` decorator**: Introduce a marker + fixture pattern so tests declare their workspace via decorator and receive a resolved `workspace` path. The fixture auto-generates CDB when a CMakeLists.txt is present. - **`CliceClient` helper methods**: Add `initialize()`, `open()`, `wait_diagnostics()`, and `open_and_wait()` to reduce boilerplate across all test files. - **Use `asyncio_mode = "auto"`**: Switch from `@pytest_asyncio.fixture` + `@pytest.mark.asyncio` to `@pytest.fixture` + auto mode for proper Pylance type inference on fixtures. - **Test cleanup**: Remove redundant section separators and docstrings, delete `tests/pyproject.toml` (config moved to `pytest.ini`). - **Format task**: Add `.cppm` to `format-cpp` glob pattern. - **CI fix**: Disable `CMAKE_CXX_SCAN_FOR_MODULES` and prefer pixi clang++ to fix macOS CI where CMake rejects module scanning. ## Test plan - [x] All 26 module test directories have CMakeLists.txt with FILE_SET CXX_MODULES - [x] generate_cdb() produces valid compile_commands.json with module flags - [x] Integration tests pass locally - [ ] CI passes on all platforms (Linux, macOS, Windows) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Tests** * Unified fixtures and client workflow: new init/open/wait helpers, workspace marker support, bounded diagnostics waiting, CMake-based compilation-database generation, and directory-backed temp-file workflows; enabled asyncio test mode. * **Chores** * Added many C++20 module test projects and test data; removed prior test pyproject in favor of pytest config; updated formatter to include .cppm files. * **Style** * Reformatted many module/source implementations to consistent multi-line function bodies. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
clice
clice is a next-generation language server designed for modern C++. Through excellent asynchronous task scheduling and intelligent caching, it achieves a lower memory footprint and faster response times.
Beyond performance, clice provides instantiation-aware template processing, supports switching header contexts between different source files (including non-self-contained headers), and offers comprehensive support for C++20 modules, from code completion to go-to-definition. Our goal is to provide C++ developers with a truly fast, precise, and intelligent development companion.
Important
Support for header contexts and C++20 modules are core features currently under active development. They will be progressively refined in upcoming releases. Stay tuned!
Getting started
Download the latest clice binary from the releases page and install the vscode extension. Then, add the following configuration to your .vscode/settings.json file:
{
// Optional: Set this to an empty string to turn off the clangd.
"clangd.path": "",
// Point this to the clice binary you downloaded.
"clice.executable": "/path/to/your/clice/executable",
}
Note
As an early version, please do not use it in a production environment. Crashes are expected, and we welcome you to submit issues.
