AST-Grep Find
Structural code search that understands syntax. Find patterns like function calls, imports, class definitions - not just text.
When to Use
- Find code patterns (ignores strings/comments)
- Search for function calls, class definitions, imports
- Refactor code with AST precision
- Rename variables/functions across codebase
Usage
Search for a pattern
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "import asyncio" --language pythonSearch in specific directory
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "async def \$FUNC(\$\$\$)" --language python --path "./src"Refactor/replace pattern
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "console.log(\$MSG)" --replace "logger.info(\$MSG)" \
--language javascriptDry run (preview changes)
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "print(\$X)" --replace "logger.info(\$X)" \
--language python --dry-runParameters
| Parameter | Description | |-----------|-------------| | `--pattern` | AST pattern to search (required) | | `--language` | Language: `python`, `javascript`, `typescript`, `go`, etc. | | `--path` | Directory to search (default: `.`) | | `--glob` | File glob pattern (e.g., `**/*.py`) | | `--replace` | Replacement pattern for refactoring | | `--dry-run` | Preview changes without applying | | `--context` | Lines of context (default: 2) |
Pattern Syntax
| Syntax | Meaning | |--------|---------| | `$NAME` | Match single node (variable, expression) | | `$$$` | Match multiple nodes (arguments, statements) | | `$_` | Match any single node (wildcard) |
Examples
# Find all function definitions
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "def \$FUNC(\$\$\$):" --language python
# Find console.log calls
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "console.log(\$\$\$)" --language javascript
# Replace print with logging
uv run python -m runtime.harness scripts/ast_grep_find.py \
--pattern "print(\$X)" --replace "logging.info(\$X)" \
--language python --dry-runvs morph/warpgrep
| Tool | Best For | |------|----------| | **ast-grep** | Structural patterns (understands code syntax) | | **warpgrep** | Fast text/regex search (20x faster grep) |
Use ast-grep when you need syntax-aware matching. Use warpgrep for raw speed.
MCP Server Required
Requires `ast-grep` server in mcp_config.json.
