## Summary
- Replace flat `CompilationContext { directory, arguments }` with a
three-layer abstraction: `ResolvedFlags` (file-independent flags) →
`CompileCommand` (+ source file) → `to_argv()` (full argv on demand)
- `ResolvedFlags.flags` never contains source file path or
`-main-file-name`, making it directly usable as a clean cache key input
(e.g. PCH sharing across files with identical preambles)
- `to_argv()` handles `-main-file-name` insertion for cc1 mode
automatically — consumers no longer need to search/replace in the
argument list
- Eliminates the pollute-then-clean anti-pattern in `lookup()` and the
manual source-file replacement in `fill_header_context_args()`
## Test plan
- [x] `pixi run format` — no changes
- [x] `pixi run unit-test` — 481 passed
- [x] `pixi run integration-test` — 113 passed

## Summary by CodeRabbit
* **Refactor**
* Unified compile-command handling across the server and tools for more
consistent argument and flag behavior (driver vs frontend modes).
* **New Features**
* Added an LRU-backed in-memory cache to improve performance and
eviction control.
* **Chores**
* Added an option to control injection of resource-directory flags
(enabled by default).
* **Tests**
* Updated unit and integration tests to adopt the new command
representation and verify cache behavior.

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.
