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](https://github.com/clice-io/clice/releases) and install the [vscode extension](https://marketplace.visualstudio.com/items?itemName=ykiko.clice-vscode). Then, add the following configuration to your `.vscode/settings.json` file:

```jsonc

{

  // 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.
