cc1-ts

按需分析 TypeScript、JavaScript、Vue，降低大型项目的内存占用。

中文

安装扩展并重载窗口即可使用，无需修改项目配置。
分析已打开文件、导入的依赖及全局类型，保留类型提示与定义跳转。
保留入口文件中副作用导入的依赖类型，例如 import 'cc1-js' 注册的全局变量。
支持内置及工作区 TypeScript 5.x/6.x；Vue 项目需安装 Vue (Official)。
支持 Windows、macOS、Linux，不适用于 TypeScript 7 原生语言服务。

未加载文件的引用搜索和自动导入建议可能不完整。需要完整项目分析时，可在当前工作区禁用本扩展。

设置

在扩展菜单中选择 Extension Settings（扩展设置），或在设置中搜索 @ext:VeigarChen.cc1-ts。支持用户级和工作区级设置，作用于整个窗口，也可以编辑 settings.json：

{
  "cc1-ts.enabled": true,
  "cc1-ts.alwaysInclude": ["**/*.d.{ts,mts,cts}"],
  "cc1-ts.debug": false,
  "cc1-ts.preserveSideEffectImports": true
}

enabled：启用按需分析，关闭后恢复完整项目分析。
alwaysInclude：始终分析的项目文件匹配规则，相对于项目根目录；列表覆盖默认规则，[] 表示不额外保留文件。
debug：在 TypeScript 服务日志中输出调试信息，可通过 TypeScript: Open TS Server log 查看。
preserveSideEffectImports：保留副作用导入注册的全局类型，关闭后跳过扫描。

修改后选择提示中的“立即重启”，或稍后执行 TypeScript: Restart TS Server。项目中的 ts-scope-trimmer.json 同名配置优先于扩展设置；显式配置 ts-scope-trimmer-plugin 的项目仍由原始插件处理。

English

Reduce memory usage by analyzing open TypeScript, JavaScript, and Vue files, their imports, and global declarations.

Install and reload VS Code. No project configuration required.
Keep type hints and definition navigation for loaded files.
Preserve dependency types registered by side-effect imports in unopened entry files, such as import 'cc1-js'.
Supports built-in/workspace TypeScript 5.x/6.x on Windows, macOS, and Linux. Vue requires Vue (Official). TypeScript 7 native is not supported.

References and auto-import suggestions may omit unloaded files. Disable the extension for the workspace when full-project analysis is needed.

Settings

Choose Extension Settings from the extension menu, or search Settings for @ext:VeigarChen.cc1-ts. User and workspace settings apply to the entire window. You can also edit settings.json:

{
  "cc1-ts.enabled": true,
  "cc1-ts.alwaysInclude": ["**/*.d.{ts,mts,cts}"],
  "cc1-ts.debug": false,
  "cc1-ts.preserveSideEffectImports": true
}

enabled: Enable on-demand analysis. Disable to restore full project analysis.
alwaysInclude: Glob patterns for project files to always analyze, relative to the project root. The list replaces the defaults; [] keeps no additional files.
debug: Write debug messages to the TypeScript server log, available through TypeScript: Open TS Server log.
preserveSideEffectImports: Preserve global types registered by side-effect imports. Disable to skip this scan.

After changes, choose Restart Now in the notification, or run TypeScript: Restart TS Server later. Matching settings in the project's ts-scope-trimmer.json take precedence over extension settings. Projects that explicitly configure ts-scope-trimmer-plugin remain managed by that plugin.
