# ast-index - Code Search for Multi-Platform Projects

Fast native Rust CLI for structural code search in Android/Kotlin/Java, iOS/Swift/ObjC, Dart/Flutter, TypeScript/JavaScript, Rust, Ruby, C#, Scala, PHP, Perl, Python, Go, C++, and Proto projects using SQLite + FTS5 index.

## Critical Rules

**ALWAYS use ast-index FIRST for any code search task.** These rules are mandatory:

1. **ast-index is the PRIMARY search tool** — use it before grep, ripgrep, or Search tool
2. **DO NOT duplicate results** — if ast-index found usages/implementations, that IS the complete answer
3. **DO NOT run grep "for completeness"** after ast-index returns results
4. **Use grep/Search ONLY when:**
   - ast-index returns empty results
   - Searching for regex patterns (ast-index uses literal match)
   - Searching for string literals inside code (`"some text"`)
   - Searching in comments content

**Why:** ast-index is 17-69x faster than grep (1-10ms vs 200ms-3s) and returns structured, accurate results.

## Prerequisites

Install the CLI before use:

```bash
brew tap defendend/ast-index
brew install ast-index
```

Initialize index in project root:

```bash
cd /path/to/project
ast-index rebuild
```

The index is stored at `~/Library/Caches/ast-index/<project-hash>/index.db` (macOS) or `~/.cache/ast-index/<project-hash>/index.db` (Linux). Rebuild deletes the DB file entirely and creates a fresh index.

## Supported Projects

| Platform | Languages | Module System |
|----------|-----------|---------------|
| Android/Java | Kotlin, Java | Gradle (build.gradle.kts), Maven (pom.xml) |
| iOS | Swift, Objective-C | SPM (Package.swift) |
| Web | TypeScript, JavaScript, React, Vue, Svelte | package.json |
| Rust | Rust | Cargo.toml |
| Ruby | Ruby, Rails, RSpec | Gemfile |
| .NET | C#, ASP.NET, Unity | *.csproj |
| Dart/Flutter | Dart | pubspec.yaml |
| Scala | Scala | Bazel (WORKSPACE, BUILD) |
| PHP | PHP | composer.json |
| Perl | Perl | Makefile.PL, Build.PL |
| Python | Python | None (*.py files) |
| Go | Go | None (*.go files) |
| Proto | Protocol Buffers (proto2/proto3) | None (*.proto files) |
| WSDL | WSDL, XSD | None (*.wsdl, *.xsd files) |
| C/C++ | C, C++ (JNI, uservices) | None (*.cpp, *.h, *.hpp files) |
| Godot | GDScript | project.godot |
| Mixed | All above | All |

Project type is auto-detected by marker files (build.gradle.kts, Package.swift, Makefile.PL, etc.). Python, Go, Proto, WSDL, and C++ files are indexed alongside main project type.

## JSON Output

Most commands support `--format json` for structured output:

```bash
ast-index search "Query" --format json
ast-index symbol "Name" --format json
ast-index class "Name" --format json
ast-index usages "Symbol" --format json
ast-index implementations "Parent" --format json
ast-index refs "Symbol" --format json
ast-index stats --format json
ast-index unused-symbols --format json
ast-index map --format json
ast-index conventions --format json
```

## Core Commands

### Universal Search

**`search`** - Perform universal search across files, symbols, and modules simultaneously.

```bash
ast-index search "Payment"           # Finds files, classes, functions matching "Payment"
ast-index search "ViewModel"         # Returns files, symbols, modules in ranked order
ast-index search "Store" --fuzzy     # Fuzzy: exact → prefix → contains matching
ast-index search "Handler" --module "core/"  # Search within a module
ast-index search "UserService"       # Find Java/Spring services
ast-index search "@RestController"   # Find Spring REST controllers (annotation search)
ast-index search "@GetMapping"       # Find GET endpoint mappings
```

### File Search

**`file`** - Find files by name pattern.

```bash
ast-index file "Fragment.kt"         # Find files ending with Fragment.kt
ast-index file "ViewController"      # Find iOS view controllers
```

### Symbol Search

**`symbol`** - Find symbols (classes, interfaces, functions, properties) by name.

```bash
ast-index symbol "PaymentInteractor" # Find exact symbol
ast-index symbol "Presenter"         # Find all presenters
ast-index symbol "Store" --fuzzy     # Fuzzy: exact → prefix → contains matching
ast-index symbol "Mapper" --in-file "payments/" --limit 10  # Scoped search
ast-index symbol "@Service"          # Find all @Service annotations
```

### Class Search

**`class`** - Find class, interface, or protocol definitions.

```bash
ast-index class "BaseFragment"       # Find Android base fragment
ast-index class "UIViewController"   # Find iOS view controller subclass
ast-index class "Store" --fuzzy      # Find all classes containing "Store"
ast-index class "Repository" --module "features/payments"  # Filter by module
ast-index class "UserController"     # Find Java/Spring controller class
```

### Usage Search

**`usages`** - Find all places where a symbol is used. Critical for refactoring.

```bash
ast-index usages "PaymentRepository" # Find all usages of repository
ast-index usages "onClick"           # Find all click handler usages
ast-index usages "fetchData" --in-file "src/api/"  # Scoped to file path
ast-index usages "Repository" --module "features/auth" --limit 100
```

Performance: ~8ms for indexed symbols.

### Cross-References

**`refs`** - Show cross-references for a symbol: definitions, imports, and usages in one view.

```bash
ast-index refs "PaymentRepository"   # Definitions + imports + usages
ast-index refs "BaseFragment" --limit 10  # Limit results per section
```

### Implementation Search

**`implementations`** - Find all classes that extend or implement a given class/interface/protocol. Supports partial name matching with relevance ranking (exact → suffix → contains).

```bash
ast-index implementations "BasePresenter"  # Find all presenter implementations
ast-index implementations "Repository"     # Find repository implementations (exact match)
ast-index implementations "Service"        # Partial: finds UserService, PaymentService impls too
ast-index implementations "ViewModel" --module "features/"  # Scoped to module
```

### Class Hierarchy

**`hierarchy`** - Display complete class hierarchy tree.

```bash
ast-index hierarchy "BaseFragment"   # Show fragment inheritance tree
```

### Caller Search

**`callers`** - Find all places that call a specific function.

```bash
ast-index callers "onClick"          # Find all onClick calls
ast-index callers "fetchUser"        # Find API call sites
```

### Call Tree

**`call-tree`** - Show complete call hierarchy going UP (who calls the callers). Supports Kotlin, Java, Swift, Perl, ObjC.

```bash
ast-index call-tree "processPayment" --depth 3 --limit 10
ast-index call-tree "getUsers"       # Java: finds callers of getUsers() method
```

### File Analysis

**`imports`** - List all imports in a specific file.

```bash
ast-index imports "path/to/File.kt"  # Show Kotlin file imports
```

**`outline`** - Show all symbols defined in a file. Uses tree-sitter for accurate parsing of all supported languages.

```bash
ast-index outline "PaymentFragment.kt"    # Show Kotlin fragment structure
ast-index outline "UserController.java"   # Show Java controller methods
ast-index outline "App.tsx"               # Show TypeScript/React components and functions
ast-index outline "handler.rs"            # Show Rust structs, impls, functions
```

### Code Quality

**`todo`** - Find TODO/FIXME/HACK comments in code.

```bash
ast-index todo                           # Find all TODO comments
ast-index todo --limit 10                # Limit results
```

**`deprecated`** - Find @Deprecated annotations.

```bash
ast-index deprecated                     # Find deprecated items
```

**`unused-symbols`** - Find potentially unused exported symbols.

```bash
ast-index unused-symbols --module path/to/module   # In specific module
ast-index unused-symbols --export-only             # Only exported (public) symbols
```

### Git/Arc Integration

**`changed`** - Show symbols changed in git/arc diff. Auto-detects VCS and base branch.

```bash
ast-index changed                        # Auto: trunk (arc) or origin/main (git)
ast-index changed --base main            # Explicit base branch
ast-index changed --base trunk           # For arc projects
```

### Public API

**`api`** - Show public API of a module. Accepts module path or module name (dots converted to slashes).

```bash
ast-index api "path/to/module"           # By path
ast-index api "module.name"              # By module name (dots → slashes)
```

## Project Insights

### Project Map

**`map`** - Show compact project overview: top directories by size with symbol kind counts. Use `--module` to drill down into a specific area with full class/inheritance details.

```bash
ast-index map                                # Summary: top 50 dirs with kind counts (~54 lines)
ast-index map --limit 20                     # Show only top 20 directories
ast-index map --module features/payments     # Detailed: classes with inheritance for a module
ast-index map --module src/core --per-dir 10 # More symbols per directory in detailed mode
ast-index map --format json                  # JSON output
```

Summary mode output (default, no `--module`):
```
Project: Android (Kotlin/Java) | 29144 files | 859 modules | top 50 of 728 dirs

  features/taxi_order/impl/          1626 files | 371 iface, 94 obj, 1834 cls
  features/masstransit/impl/          862 files | 165 obj, 1261 cls, 280 iface
```

Detailed mode output (with `--module`):
```
features/payments/impl/ (250 files)
  PaymentInteractor : class > BaseInteractor
  PaymentRepository : interface
  PaymentMapper : class
```

### Project Conventions

**`conventions`** - Auto-detect architecture patterns, frameworks, and naming conventions from the indexed codebase. Runs read-only SQL queries — no file scanning needed.

```bash
ast-index conventions                        # Text output (~30 lines)
ast-index conventions --format json          # JSON output
```

Detects:
- **Architecture**: Clean Architecture, Feature-sliced, BLoC, MVC, MVVM, MVP, Redux, Composition API, Hooks
- **Frameworks**: DI (Hilt, Dagger, Koin), Async (Coroutines, RxJava, Combine), Network (Retrofit, OkHttp), DB (Room, Realm), UI (Compose, SwiftUI, React, Flutter), Testing (JUnit, Kotest, XCTest, pytest, Jest)
- **Naming patterns**: ViewModel, Repository, UseCase, Service, Controller, Fragment, etc. (with counts)

## Common Flags

Most search commands (`search`, `symbol`, `class`, `usages`, `implementations`) support:

| Flag | Description |
|------|-------------|
| `--fuzzy` | Fuzzy search: exact match → prefix match → contains match |
| `--in-file <PATH>` | Filter results by file path (substring match) |
| `--module <PATH>` | Filter results by module path (substring match) |
| `--limit <N>` | Max results to return |
| `--format json` | JSON output for structured processing |

**When to use `--fuzzy`:** When you don't know the exact name. `ast-index class "Store" --fuzzy` finds `Store`, `StoreImpl`, `AppStore`, `DataStoreRepository`, etc. The `--fuzzy` flag performs three-stage matching: exact match first, then prefix match, then contains match.

## Index Management

```bash
ast-index rebuild                        # Full rebuild with dependencies
ast-index rebuild --no-deps              # Skip module dependency indexing
ast-index rebuild --no-ignore            # Include gitignored files (build/, etc.)
ast-index rebuild --sub-projects         # Index each sub-project separately (large monorepos)
ast-index rebuild -j 32                  # Use 32 threads (for network/FUSE filesystems)
ast-index rebuild -v                     # Verbose logging with timing per step
ast-index update                         # Incremental update (changed files only)
ast-index stats                          # Show index statistics
ast-index clear                          # Delete index for current project
ast-index restore /path/to/index.db      # Restore index from a .db file
ast-index watch                          # Watch for file changes and auto-update index
```

### Directory-Scoped Search

When running search from a subdirectory, results are automatically limited to that subtree (the index DB in cache is used to detect the project root):

```bash
cd /project/root
ast-index rebuild                        # Index entire project, creates .ast-index-root
ast-index search "Payment"              # Finds results across entire project

cd /project/root/services/payments
ast-index search "Payment"              # Only finds results within services/payments/
ast-index class "PaymentService"        # Only classes in services/payments/ subtree
```

This works with all search commands: `search`, `symbol`, `class`, `implementations`, `usages`.

## Multi-Root Projects

Add additional source roots for monorepos or multi-project setups. Extra roots are indexed alongside the primary project and their module dependencies are included.

```bash
ast-index add-root /path/to/other/source    # Add source root (warns on overlap)
ast-index add-root ./subdir --force         # Force add even if inside project root
ast-index remove-root /path/to/other/source # Remove source root
ast-index list-roots                        # List configured roots
```

## Utility Commands

```bash
ast-index version                    # Show CLI version
ast-index help                       # Show help message
ast-index help <command>             # Show help for specific command
ast-index install-claude-plugin      # Install Claude Code plugin to ~/.claude/plugins/
```

## Programmatic Access (SQL & SDK)

For complex analysis that requires combining multiple queries, filtering, or aggregation — use direct SQL access instead of chaining multiple commands.

### Structural Search (ast-grep)

Structural code search using AST patterns. Requires `sg` (ast-grep) installed.

```bash
# Simple pattern matching
ast-index agrep "router.launch($$$)" --lang kotlin
ast-index agrep "@Inject constructor($$$)" --lang kotlin
ast-index agrep "suspend fun $NAME($$$)" --lang kotlin

# Find classes extending a specific base
ast-index agrep "class $NAME : BasePresenter($$$)" --lang kotlin

# Find async functions (Swift)
ast-index agrep "func $NAME($$$) async" --lang swift

# Find React components
ast-index agrep "export default function $NAME($$$)" --lang typescript

# JSON output for programmatic use
ast-index agrep "@Composable fun $NAME($$$)" --lang kotlin --json
```

**Pattern syntax** (ast-grep):
- `$NAME` — matches a single AST node (captures as metavariable)
- `$$$` — matches zero or more AST nodes (variadic)
- Everything else is literal pattern matching against the AST

**When to use `agrep` vs built-in commands:**
- `composables`, `inject`, `suspend` → use built-in (faster, pre-configured)
- Custom structural patterns, negative matching, context queries → use `agrep`

### Raw SQL Query

```bash
# Execute any SELECT query against the index database (JSON output)
ast-index query "SELECT s.name, s.kind, f.path FROM symbols s JOIN files f ON s.file_id = f.id WHERE s.kind = 'class'"

# With limit
ast-index query "SELECT * FROM symbols WHERE name LIKE '%Service%'" --limit 50

# Complex joins — find classes that implement an interface but have no usages
ast-index query "SELECT s.name, f.path FROM symbols s JOIN files f ON s.file_id = f.id JOIN inheritance i ON s.id = i.child_id WHERE i.parent_name = 'Repository' AND s.name NOT IN (SELECT name FROM refs)"

# Find files with most symbols (complexity hotspots)
ast-index query "SELECT f.path, COUNT(*) as sym_count FROM symbols s JOIN files f ON s.file_id = f.id GROUP BY f.id ORDER BY sym_count DESC LIMIT 20"

# Find unused classes (defined but never referenced)
ast-index query "SELECT s.name, s.kind, f.path FROM symbols s JOIN files f ON s.file_id = f.id WHERE s.kind IN ('class', 'interface') AND s.name NOT IN (SELECT name FROM refs) AND s.name NOT IN (SELECT parent_name FROM inheritance)"

# Module dependency analysis — find modules with most dependencies
ast-index query "SELECT m.name, COUNT(*) as dep_count FROM module_deps md JOIN modules m ON md.module_id = m.id GROUP BY m.id ORDER BY dep_count DESC"

# CTE — transitive dependency chain
ast-index query "WITH RECURSIVE chain AS (SELECT md.dep_module_id, m.name, 1 as depth FROM module_deps md JOIN modules m ON md.dep_module_id = m.id WHERE md.module_id = (SELECT id FROM modules WHERE name LIKE '%payments%') UNION ALL SELECT md.dep_module_id, m.name, c.depth + 1 FROM chain c JOIN module_deps md ON md.module_id = c.dep_module_id JOIN modules m ON md.dep_module_id = m.id WHERE c.depth < 5) SELECT DISTINCT name, depth FROM chain ORDER BY depth, name"
```

**Security**: Only `SELECT`, `WITH`, and `EXPLAIN` queries allowed. Mutations (`INSERT`, `UPDATE`, `DELETE`, `DROP`) are blocked.

### Database Schema

```bash
# Show all tables with columns and row counts (JSON)
ast-index schema
```

Key tables:
| Table | Description | Key columns |
|-------|-------------|-------------|
| `files` | Indexed source files | `path`, `mtime`, `size` |
| `symbols` | Classes, functions, properties, etc. | `name`, `kind`, `line`, `file_id`, `signature` |
| `symbols_fts` | FTS5 full-text search on symbols | `name`, `signature` |
| `inheritance` | Parent-child type relationships | `child_id`, `parent_name`, `kind` |
| `refs` | Symbol references/usages | `name`, `line`, `file_id`, `context` |
| `modules` | Build modules (Gradle, Maven, etc.) | `name`, `path`, `kind` |
| `module_deps` | Module → module dependencies | `module_id`, `dep_module_id` |
| `transitive_deps` | Pre-computed transitive deps | `module_id`, `dependency_id`, `depth` |
| `xml_usages` | Android XML layout class usages | `class_name`, `file_path` |
| `resources` | Android resource definitions | `type`, `name`, `file_path` |

### Direct Database Access (SDK / Scripting)

```bash
# Get the SQLite database path for external tools
ast-index db-path
# Output: /Users/me/.cache/ast-index/abc123/index.db
```

Use this path with any language that supports SQLite:

```python
import sqlite3, json
db_path = subprocess.check_output(["ast-index", "db-path"]).decode().strip()
conn = sqlite3.connect(db_path)

# Example: find all classes implementing an interface with no references
unused_impls = conn.execute("""
    SELECT s.name, f.path, i.parent_name
    FROM symbols s
    JOIN files f ON s.file_id = f.id
    JOIN inheritance i ON s.id = i.child_id
    WHERE s.name NOT IN (SELECT name FROM refs)
    ORDER BY i.parent_name, s.name
""").fetchall()
for name, path, parent in unused_impls:
    print(f"  {name} implements {parent} — {path}")
```

**When to use `query` vs predefined commands:**
- Simple lookups → use `search`, `class`, `usages` (faster, formatted output)
- Complex joins, aggregation, negative conditions → use `query` (one call instead of N)
- Batch analysis, scripting, CI pipelines → use `db-path` + direct SQLite access

## Performance Reference

| Command | Time | Notes |
|---------|------|-------|
| search | ~10ms | Indexed FTS5 search |
| class | ~1ms | Direct index lookup |
| usages | ~8ms | Indexed reference search |
| imports | ~0.3ms | File-based lookup |
| callers | ~1s | Grep-based search |
| map | ~1-3s | SQL aggregation (scales with project size) |
| conventions | ~1-4s | SQL aggregation + import matching |
| rebuild | ~25s–5m | Full project indexing (depends on size) |

## Workflow Recommendations

1. Run `ast-index rebuild` once in project root to build the index
2. **Start a session** with `ast-index conventions` + `ast-index map` to understand project structure (~80 lines, ~500 tokens)
3. Use `ast-index map --module <path>` to drill down into specific areas
4. Use `ast-index search` for quick universal search when exploring
5. Use `ast-index class` for precise class/interface lookup
6. Use `ast-index usages` to find all references before refactoring
7. Use `ast-index implementations` to understand inheritance
8. Use `ast-index changed --base main` before code review
9. Run `ast-index update` periodically to keep index fresh
