针对 Copilot CLI 的新 C++ 语言服务器配置技能

The Microsoft C++ Language Server is now available as a plugin on the Copilot Plugins marketplace. It includes a new built-in setup skill that helps automate project setup, making it easier to generate and maintain the compile_commands.json file the language server needs to understand your code. The C++ language server relies on a compile_commands.json file to provide precise semantic intelligence (i.e., symbol navigation, diagnostics, and code changes that reflect how your compiler actually sees the code). Previously, creating this file required manual steps that varied by build system. The new setup skills handle this automatically for CMake and MSBuild projects, and they provide a repeatable pattern for custom build systems. The C++ language server can now be installed directly as a Copilot CLI plugin: /plugin install cpp-language-server@copilot-plugins This replaces the previous npm-based installation and simplifies getting started and staying updated with the latest releases on Windows, Linux, and macOS. The new generate compile commands skill lets you generate or refresh your compile_commands.json directly from Copilot CLI. Simply say “regenerate compile commands” or “load project” and the skill will configure your compilation database based on your project type and platform. The language server automatically watches for changes to compile_commands.json , so updates take effect without restarting. If you don’t already have a compile_commands.json generated from your CMake builds, the recommended path is to use the skill to generate one for you. Alternatively, you can pass -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE when configuring CMake to directly produce the file from your build. CMake has native support for compile command generation, and the skill helps configure the project so the language server has the compilation database it needs. For MSBuild-based projects, you have two options: Guided setup: Use the skill to onboard the project by saying “regenerate compile commands” or “load project.” The skill produces the configuration needed for the language server. Manual generation: Use the sample extractor application to generate compile_commands.json from your MSBuild project. While it works out-of-the-box for many projects, it may require adaptation for complex configurations.
