C++ language support powered by clice, a language server written from scratch on LLVM/Clang: template-aware completion inside generic code, first-class compilation contexts for headers and build configurations, and native C++20 modules support.
Getting started
- Install this extension — the clice server for your platform is bundled, no download or extra setup needed.
- Open a C++ project with a
compilation database.
For CMake:
cmake -B build -DCMAKE_EXPORT_COMPILE_COMMANDS=ON. clice searches the workspace root and its immediate subdirectories (e.g.build/) automatically.
See the documentation for configuration via
clice.toml and the full feature guide.
Release channels
Stable versions use even minor numbers; daily pre-releases built from main
use odd ones. Use Switch to Pre-Release Version on the extension page to
follow the pre-release channel. Per-commit builds and standalone server
downloads live on the GitHub releases and CI pages.
Settings
| Setting | Default | Description |
|---|---|---|
clice.executable |
(bundled) | Path to a clice binary to use instead of the bundled one. |
clice.mode |
pipe |
Server transport; socket connects to an external server (debugging). |
clice.host |
127.0.0.1 |
Host for socket mode. |
clice.port |
50051 |
Port for socket mode. |
Troubleshooting
Server logs live in the clice output channel, which also prints the
on-disk log directory at startup (Session log directory: — by default
under ~/.cache/clice/<workspace>-<hash>/logs/). If the server crashes,
please attach the newest log from there to a
GitHub issue — releases ship
symbol packages that let us reconstruct the exact stack.
Extension development is documented in the contributor guide.
