1	# AST-Grep Find
2
3	Structural code search that understands syntax. Find patterns like function calls, imports, class definitions - not just text.
4
5	## When to Use
6
7	- Find code patterns (ignores strings/comments)
8	- Search for function calls, class definitions, imports
9	- Refactor code with AST precision
10	- Rename variables/functions across codebase
11
12	## Usage
13
14	### Search for a pattern
15	```bash
16	uv run python -m runtime.harness scripts/ast_grep_find.py \
17	--pattern "import asyncio" --language python
18	```
19
20	### Search in specific directory
21	```bash
22	uv run python -m runtime.harness scripts/ast_grep_find.py \
23	--pattern "async def \$FUNC(\$\$\$)" --language python --path "./src"
24	```
25
26	### Refactor/replace pattern
27	```bash
28	uv run python -m runtime.harness scripts/ast_grep_find.py \
29	--pattern "console.log(\$MSG)" --replace "logger.info(\$MSG)" \
30	--language javascript
31	```
32
33	### Dry run (preview changes)
34	```bash
35	uv run python -m runtime.harness scripts/ast_grep_find.py \
36	--pattern "print(\$X)" --replace "logger.info(\$X)" \
37	--language python --dry-run
38	```
39
40	## Parameters
41
42	\| Parameter \| Description \|
43	\|-----------\|-------------\|
44	\| `--pattern` \| AST pattern to search (required) \|
45	\| `--language` \| Language: `python`, `javascript`, `typescript`, `go`, etc. \|
46	\| `--path` \| Directory to search (default: `.`) \|
47	\| `--glob` \| File glob pattern (e.g., `*/.py`) \|
48	\| `--replace` \| Replacement pattern for refactoring \|
49	\| `--dry-run` \| Preview changes without applying \|
50	\| `--context` \| Lines of context (default: 2) \|
51
52	## Pattern Syntax
53
54	\| Syntax \| Meaning \|
55	\|--------\|---------\|
56	\| `$NAME` \| Match single node (variable, expression) \|
57	\| `$$$` \| Match multiple nodes (arguments, statements) \|
58	\| `$_` \| Match any single node (wildcard) \|
59
60	## Examples
61
62	```bash
63	# Find all function definitions
64	uv run python -m runtime.harness scripts/ast_grep_find.py \
65	--pattern "def \$FUNC(\$\$\$):" --language python
66
67	# Find console.log calls
68	uv run python -m runtime.harness scripts/ast_grep_find.py \
69	--pattern "console.log(\$\$\$)" --language javascript
70
71	# Replace print with logging
72	uv run python -m runtime.harness scripts/ast_grep_find.py \
73	--pattern "print(\$X)" --replace "logging.info(\$X)" \
74	--language python --dry-run
75	```
76
77	## vs morph/warpgrep
78
79	\| Tool \| Best For \|
80	\|------\|----------\|
81	\| ast-grep \| Structural patterns (understands code syntax) \|
82	\| warpgrep \| Fast text/regex search (20x faster grep) \|
83
84	Use ast-grep when you need syntax-aware matching. Use warpgrep for raw speed.
85
86	## MCP Server Required
87
88	Requires `ast-grep` server in mcp_config.json.
