一、核心架构

1.1 WorkspaceAnalyzer

// crates/sage-core/src/workspace/analyzer.rs
pub struct WorkspaceAnalyzer {
    config: WorkspaceConfig,
    detector: ProjectTypeDetector,
    pattern_matcher: PatternMatcher,
}

impl WorkspaceAnalyzer {
    /// 分析工作区
    pub async fn analyze(&self, path: &Path) -> Result<AnalysisResult, WorkspaceError> {
        // 1. 检测项目类型
        let project_type = self.detector.detect(path)?;

        // 2. 获取文件统计
        let file_stats = self.collect_file_stats(path)?;

        // 3. 查找重要文件
        let important_files = self.pattern_matcher.find_important_files(path)?;

        // 4. 分析依赖
        let dependencies = if self.config.analyze_dependencies {
            self.analyze_dependencies(path, &project_type)?
        } else {
            None
        };

        // 5. 获取 Git 信息
        let git_info = if self.config.analyze_git {
            git::get_git_info(path).ok()
        }  {
            
        };

        
          = entry_points::(path, &project_type)?;

        (AnalysisResult {
            project_type,
            file_stats,
            important_files,
            dependencies,
            git_info,
            entry_points,
            structure: .(path)?,
        })
    }
}

1.2 分析结果

// crates/sage-core/src/workspace/models.rs
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct AnalysisResult {
    /// 项目类型
    pub project_type: ProjectType,
    /// 文件统计
    pub file_stats: FileStats,
    /// 重要文件
    pub important_files: Vec<ImportantFile>,
    /// 依赖信息
    pub dependencies: Option<DependencyInfo>,
    /// Git 信息
    pub git_info: Option<GitInfo>,
    /// 入口点
    pub entry_points: Vec<EntryPoint>,
    /// 项目结构
    pub structure: ProjectStructure,
}

            Self::TypeScript => &["ts", "tsx", "mts"],
            // ...
        }
    }
}

2.3 框架类型

    CMake,       // C/C++
    Make,        // 通用
    Bazel,       // 通用
}

---

三、ProjectTypeDetector

3.1 检测流程

// crates/sage-core/src/workspace/detector/mod.rs
pub struct ProjectTypeDetector {
    detectors: Vec<Box<dyn LanguageDetector>>,
}

impl ProjectTypeDetector {
    pub fn new() -> Self {
        Self {
            detectors: vec![
                Box::new(RustDetector),
                Box::new(PythonDetector),
                Box::new(NodeDetector),
                Box::new(GoDetector),
                Box::new(JvmDetector),
            ],
        }
    }

    /// 检测项目类型
    pub fn detect(&self, path: &Path) -> Result<ProjectType, WorkspaceError> {
        let mut languages = Vec::new();
        let mut frameworks = Vec::new();
        let mut build_systems = Vec::new();

        for   &.detectors {
              (result) = detector.(path)? {
                languages.(result.language);
                frameworks.(result.frameworks);
                build_systems.(result.build_systems);
            }
        }

        
          = .(&languages, path);

        (ProjectType {
            primary_language: primary,
            secondary_languages: languages.().(|l| *l != primary).(),
            frameworks,
            build_systems,
            runtime: .(path)?,
            test_frameworks: .(path)?,
        })
    }
}

3.2 语言检测器 Trait

pub trait LanguageDetector: Send + Sync {
    /// 检测语言
    fn detect(&self, path: &Path) -> Result<Option<DetectionResult>, WorkspaceError>;

    /// 支持的语言
    fn language(&self) -> LanguageType;
}

#[derive(Debug)]
pub struct DetectionResult {
    pub language: LanguageType,
    pub frameworks: Vec<FrameworkType>,
    pub build_systems: Vec<BuildSystem>,
    pub confidence: f32,
}

3.3 Rust 检测器示例

// crates/sage-core/src/workspace/detector/detectors/rust.rs
pub struct RustDetector;

impl LanguageDetector for RustDetector {
    fn detect(&self, path: &Path) -> Result<Option<DetectionResult>, WorkspaceError> {
        let cargo_toml = path.join("Cargo.toml");

        if !cargo_toml.exists() {
            return Ok(None);
        }

        let content = fs::read_to_string(&cargo_toml)?;
        let mut frameworks = Vec::new();
        let build_systems = vec![BuildSystem::Cargo];

        // 检测框架
        if content.contains("actix-web") {
            frameworks.push(FrameworkType::Actix);
        }
        if content.contains("rocket") {
            frameworks.push(FrameworkType::Rocket);
        }
        if content.contains("axum") {
            frameworks.(FrameworkType::Axum);
        }
         content.() {
            frameworks.(FrameworkType::Tauri);
        }

        ((DetectionResult {
            language: LanguageType::Rust,
            frameworks,
            build_systems,
            confidence: ,
        }))
    }

     (&)  LanguageType {
        LanguageType::Rust
    }
}

---

四、依赖分析

4.1 DependencyInfo

// crates/sage-core/src/workspace/models.rs
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct DependencyInfo {
    /// 直接依赖
    pub direct: Vec<Dependency>,
    /// 开发依赖
    pub dev: Vec<Dependency>,
    /// 可选依赖
    pub optional: Vec<Dependency>,
    /// 依赖总数
    pub total_count: usize,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Dependency {
    pub name: String,
    pub version: Option<String>,
    pub source: DependencySource,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
pub enum DependencySource {
    Registry(String),  // 如 crates.io, npm
    Git(String),       // Git URL
    Path(PathBuf),     // 本地路径
}

4.2 Cargo 依赖分析

// crates/sage-core/src/workspace/dependencies/cargo.rs
pub fn analyze_cargo_dependencies(path: &Path) -> Result<DependencyInfo, WorkspaceError> {
    let cargo_toml = path.join("Cargo.toml");
    let content = fs::read_to_string(&cargo_toml)?;
    let manifest: toml::Value = toml::from_str(&content)?;

    let mut direct = Vec::new();
    let mut dev = Vec::new();

    // 解析 [dependencies]
    if let Some(deps) = manifest.get("dependencies").and_then(|d| d.as_table()) {
        for (name, spec) in deps {
            direct.push(parse_cargo_dependency(name, spec));
        }
    }

    // 解析 [dev-dependencies]
    if let Some(deps) = manifest.get("dev-dependencies").and_then(|d| d.as_table()) {
        for (name, spec)  deps {
            dev.((name, spec));
        }
    }

    (DependencyInfo {
        total_count: direct.() + dev.(),
        direct,
        dev,
        optional: ::(),
    })
}

---

五、模式匹配

5.1 PatternMatcher

// crates/sage-core/src/workspace/patterns/matcher.rs
pub struct PatternMatcher {
    patterns: Vec<ProjectPattern>,
}

impl PatternMatcher {
    /// 查找重要文件
    pub fn find_important_files(&self, path: &Path) -> Result<Vec<ImportantFile>, WorkspaceError> {
        let mut results = Vec::new();

        for pattern in &self.patterns {
            for file_pattern in &pattern.files {
                let glob = glob::glob(&format!("{}/{}", path.display(), file_pattern))?;

                for entry in glob.flatten() {
                    results.push(ImportantFile {
                        path: entry.clone(),
                        file_type: pattern.file_type,
                        description: pattern.description.clone(),
                    });
                }
            }
        }

        Ok(results)
    }
}

5.2 重要文件类型

// crates/sage-core/src/workspace/patterns/types.rs
#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum ImportantFileType {
    /// 配置文件
    Config,
    /// 构建文件
    Build,
    /// 依赖声明
    Dependencies,
    /// 文档
    Documentation,
    /// 入口点
    EntryPoint,
    /// 测试
    Test,
    /// CI/CD
    Ci,
    /// Docker
    Docker,
    /// 环境变量
    Environment,
}

#[derive(Debug, Clone)]
pub struct ImportantFile {
    pub path: PathBuf,
    pub file_type: ImportantFileType,
    pub description: String,
}

5.3 语言模式定义

// crates/sage-core/src/workspace/patterns/language_patterns.rs
pub fn get_rust_patterns() -> Vec<ProjectPattern> {
    vec![
        ProjectPattern {
            file_type: ImportantFileType::Build,
            files: vec!["Cargo.toml", "Cargo.lock"],
            description: "Rust package manifest".to_string(),
        },
        ProjectPattern {
            file_type: ImportantFileType::EntryPoint,
            files: vec!["src/main.rs", "src/lib.rs"],
            description: "Rust entry point".to_string(),
        },
        ProjectPattern {
            file_type: ImportantFileType::Config,
            files: vec![".cargo/config.toml", "rust-toolchain.toml"],
            description: "Rust configuration".to_string(),
        },
    ]
}

pub fn get_node_patterns() -> Vec<ProjectPattern> {
    vec![
        ProjectPattern {
            file_type: ImportantFileType::Dependencies,
            files: vec!["package.json", "package-lock.json", "yarn.lock", "pnpm-lock.yaml"],
            description: "Node.js package manifest".to_string(),
        },
        ProjectPattern {
            file_type: ImportantFileType::Config,
            files: vec!["tsconfig.json", ".eslintrc*", ".prettierrc*"],
            description: .(),
        },
    ]
}

---

六、Git 信息

// crates/sage-core/src/workspace/git.rs
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct GitInfo {
    /// 当前分支
    pub branch: Option<String>,
    /// 远程 URL
    pub remote_url: Option<String>,
    /// 最后提交 Hash
    pub last_commit: Option<String>,
    /// 是否有未提交更改
    pub has_changes: bool,
    /// 未追踪文件数
    pub untracked_count: usize,
}

pub fn get_git_info(path: &Path) -> Result<GitInfo, WorkspaceError> {
    let repo = git2::Repository::discover(path)?;

    let branch = repo.head()
        .ok()
        .and_then(|h| h.shorthand().map(String::from));

    let remote_url = repo.find_remote("origin")
        .ok()
        .and_then(|r| r.url().map(String::from));

      = repo.()
        .()
        .(|h| h.().())
        .(|c| c.().()[..].());

      = repo.()?;
      = !statuses.();
      = statuses.()
        .(|s| s.().(git2::Status::WT_NEW))
        .();

    (GitInfo {
        branch,
        remote_url,
        last_commit,
        has_changes,
        untracked_count,
    })
}

---

七、使用示例

use sage_core::workspace::{WorkspaceAnalyzer, WorkspaceConfig};

// 创建分析器
let config = WorkspaceConfig::default();
let analyzer = WorkspaceAnalyzer::new(config);

// 分析工作区
let result = analyzer.analyze(Path::new(".")).await?;

// 输出项目类型
println!("Primary language: {:?}", result.project_type.primary_language);
println!("Frameworks: {:?}", result.project_type.frameworks);

// 输出文件统计
println!("Total files: {}", result.file_stats.total_files);
println!("By extension: {:?}", result.file_stats.by_extension);

// 输出重要文件
for file in &result.important_files {
    println!("{}: {:?}", file.path.display(), file.file_type);
}

// 输出 Git 信息
if let Some(git) = &result.git_info {
    println!("Branch: {:?}", git.branch);
    println!("Has changes: {}", git.has_changes);
}

---

八、开发指南

8.1 添加新语言检测器

1. 创建检测器：

// workspace/detector/detectors/new_lang.rs
pub struct NewLangDetector;

impl LanguageDetector for NewLangDetector {
    fn detect(&self, path: &Path) -> Result<Option<DetectionResult>, WorkspaceError> {
        // 实现检测逻辑
    }

    fn language(&self) -> LanguageType {
        LanguageType::NewLang
    }
}

2. 在 LanguageType 添加变体

3. 添加语言模式到 language_patterns.rs

4. 在 ProjectTypeDetector::new() 注册检测器

8.2 添加依赖分析器

在 dependencies/ 目录添加新分析器，实现解析逻辑。

九、相关模块

• sage-tool-development - 工具开发（工作区上下文）
• sage-agent-execution - Agent 执行（工作区信息）
• sage-prompts - Prompt 生成（项目上下文注入）
