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.

Description
clice.executable

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.
