workspace

Workspace Package

The workspace package provides workspace detection and identification for multi-workspace MCP support.

Features

• Auto-detection: Automatically detect workspace root from file paths
• Multi-marker support: Detects various project types (.git, go.mod, package.json, etc.)
• Stable IDs: Generates consistent workspace identifiers using SHA256 hashing
• Caching: Built-in cache to avoid redundant detection
• Extensible: Customizable markers and exclusion patterns

Usage

Basic Detection

import "github.com/doITmagic/rag-code-mcp/internal/workspace"

// Create detector
detector := workspace.NewDetector()

// Detect from file path
info, err := detector.DetectFromPath("/home/user/projects/my-app/src/main.go")
if err != nil {
    log.Fatal(err)
}

fmt.Println("Workspace:", info.Root)
fmt.Println("ID:", info.ID)
fmt.Println("Type:", info.ProjectType)
fmt.Println("Collection:", info.CollectionName())

Detection from MCP Parameters

// MCP tool receives parameters
params := map[string]interface{}{
    "file_path": "/home/user/project/internal/handler.go",
    "query": "search term",
}

// Detect workspace from params
info, err := detector.DetectFromParams(params)
if err != nil {
    log.Fatal(err)
}

// Use workspace-specific collection
collectionName := info.CollectionName() // "ragcode-a3f4b8c9d2e1"

Using Cache

// Create cache with 5 minute TTL
cache := workspace.NewCache(5 * time.Minute)

// Check cache before detection
if cached := cache.Get(filePath); cached != nil {
    return cached
}

// Detect and cache
info, err := detector.DetectFromPath(filePath)
cache.Set(filePath, info)

Custom Configuration

detector := workspace.NewDetector()

// Customize markers
detector.SetMarkers([]string{
    ".git",
    "package.json",
    "deno.json",      // Custom marker
    "requirements.txt", // Python projects
})

// Customize exclusions
detector.SetExcludePatterns([]string{
    "/node_modules/",
    "/dist/",
    "/.next/",
    "/target/",
})

API Reference

Types

Info

Represents detected workspace information.

type Info struct {
    Root        string    // Absolute path to workspace root
    ID          string    // Unique workspace identifier (12-char hash)
    ProjectType string    // Detected project type (go, nodejs, python, etc.)
    Markers     []string  // Found workspace markers
    DetectedAt  time.Time // Detection timestamp
}

func (i *Info) CollectionName() string // Returns "ragcode-{ID}"

Metadata

Workspace metadata for storage in Qdrant.

type Metadata struct {
    WorkspaceID  string    // Workspace unique ID
    RootPath     string    // Workspace root path
    LastIndexed  time.Time // Last indexing time
    FileCount    int       // Number of indexed files
    ChunkCount   int       // Number of indexed chunks
    Status       string    // "indexed", "indexing", "failed", "pending"
    ProjectType  string    // Project type
    Markers      []string  // Workspace markers
    ErrorMessage string    // Error if status is "failed"
}

Detector

NewDetector() *Detector

Creates detector with default markers.

Default markers (in priority order):

• .git - Git repository
• go.mod - Go project
• package.json - Node.js project
• Cargo.toml - Rust project
• pyproject.toml - Python project (modern)
• setup.py - Python project (legacy)
• pom.xml - Maven project
• build.gradle - Gradle project
• .project - Generic project
• .vscode - VS Code workspace

DetectFromPath(filePath string) (*Info, error)

Detects workspace from a file path. Walks up directory tree looking for workspace markers.

Returns fallback workspace (file's directory) if no markers found.

DetectFromParams(params map[string]interface{}) (*Info, error)

Detects workspace from MCP tool parameters. Looks for file paths in common parameter names:

• file_path, filePath
• path, file
• source_file, target_file
• directory, dir

Falls back to current working directory if no paths found.

SetMarkers(markers []string)

Sets custom workspace markers.

SetExcludePatterns(patterns []string)

Sets path patterns to exclude from detection.

Cache

NewCache(ttl time.Duration) *Cache

Creates cache with specified TTL.

Get(key string) *Info

Retrieves cached workspace info. Returns nil if not found or expired.

Set(key string, info *Info)

Stores workspace info in cache.

Clear()

Removes all entries from cache.

CleanExpired() int

Removes expired entries. Returns number of entries removed.

Size() int

Returns number of cached entries.

Workspace ID Generation

Workspace IDs are generated using SHA256 hash of the absolute workspace path:

func generateWorkspaceID(rootPath string) string {
    h := sha256.Sum256([]byte(rootPath))
    return hex.EncodeToString(h[:])[:12] // First 12 chars
}

Properties:

• ✅ Stable: Same path always generates same ID
• ✅ Unique: Different paths generate different IDs
• ✅ Collision-resistant: 12-char hex = 48 bits (281 trillion combinations)
• ✅ Readable: Short enough for logs and debugging

Examples:

/home/user/projects/do-ai       → a3f4b8c9d2e1
/home/user/projects/other-app   → 5e6f7g8h9i0j
/opt/workspace/backend          → 1a2b3c4d5e6f

Project Type Detection

Automatically infers project type from markers:

For Laravel projects, the detector uses the combination of composer.json + artisan and normalizes the project type to a PHP/Laravel variant (e.g. laravel, php-laravel), so that the language_manager can automatically select the PHP + Laravel analyzer.

Integration Examples

MCP Tool Integration

type SearchTool struct {
    detector *workspace.Detector
    cache    *workspace.Cache
}

func (t *SearchTool) Execute(ctx context.Context, params map[string]interface{}) (string, error) {
    // Detect workspace from params
    info, err := t.detector.DetectFromParams(params)
    if err != nil {
        return "", err
    }
    
    // Get workspace-specific collection
    collection := info.CollectionName()
    
    // Use collection for search
    results, err := t.searchInCollection(ctx, collection, params)
    return results, err
}

Background Cleanup

// Periodic cache cleanup
func startCacheCleanup(cache *workspace.Cache) {
    ticker := time.NewTicker(10 * time.Minute)
    go func() {
        defer ticker.Stop()
        for range ticker.C {
            removed := cache.CleanExpired()
            log.Printf("Cleaned %d expired workspace cache entries", removed)
        }
    }()
}

Testing

Run tests:

go test ./internal/workspace/...

Run with coverage:

go test -cover ./internal/workspace/...

Run benchmarks:

go test -bench=. ./internal/workspace/...

Performance

• Detection: ~0.1ms (with filesystem access)
• Cache hit: ~0.001ms (memory lookup)
• ID generation: ~0.01ms (SHA256 hash)

Cache significantly improves performance for repeated calls with same paths.
