## Summary Initial integration of `CompileGraph` (#375) into `MasterServer`, enabling basic end-to-end C++20 module support: on-demand PCM building, dependency-ordered compilation, cascade invalidation on save, and diagnostic integration. This is a **first-pass implementation** — the core pipeline works, but there are known areas for follow-up: - PCM files go to system temp dir instead of `.clice/cache/`; no disk cleanup on invalidation - `run_build_drain` scans imports itself rather than delegating fully to CompileGraph - No incremental/partial rebuild (full PCM rebuild on any change) - Cycle detection is tested at unit level but integration-level coverage is minimal ## Changes ### Module dependency compilation (`master_server.cpp`) Before sending a file to the stateful worker, `run_build_drain` now: 1. Scans imports via `scan_precise()` to discover module dependencies 2. Compiles each dep through `compile_graph->compile()`, which recursively builds transitive PCMs 3. Handles implementation units — `module M;` implicitly needs the interface PCM 4. Passes all built PCMs to the stateful worker, excluding the file's own PCM 5. Skips compile on dep failure and resets `build_running` / `drain_scheduled` 6. Re-lookups iterators after `co_await` to avoid use-after-invalidation ### Cascade invalidation (`didSave` / `didClose`) - `didSave`: calls `compile_graph->update()` to mark transitive dependents dirty, removes stale PCM paths, schedules rebuilds for open dirtied files - `didClose`: cancels in-flight compilations for the closed file ### Other fixes in this PR - Debounce timers switched to `shared_ptr` to prevent use-after-free when `didClose` destroys the timer mid-wait - `fill_compile_args` returns `bool`; callers handle empty CDB gracefully - Adapt all `PositionMapper` call sites to the new `optional` return API from eventide ## Test plan - [x] 25 C++ unit tests for CompileGraph (cycles, partial failure, cancel, update, empty graph) - [x] 24 C++ integration tests with real clang PCM compilation - [x] 3 worker-level module tests (BuildPCM, PCM-dependent compile, multi-module) - [x] 26 Python LSP integration tests (single module through circular deps, hover, error diagnostics) - [x] 371 unit tests + 54 integration tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- 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.
