ast-grep code search

Use run for a single-node pattern:

ast-grep run --pattern 'console.log($$$ARGS)' --lang javascript src

Use scan --inline-rules for relational or combined conditions. Check uncertain rules against a positive and a negative example with --stdin.

Relational stopBy changes the search boundary:

• neighbor (default) checks immediate relations.
• end traverses to the root for inside or to the leaves for has, including nested scopes.
• A rule-valued stopBy stops at a matching syntax node. That node can also match the relational rule.

For function-local queries, bound traversal so nested function bodies cannot satisfy an outer function's rule.

Single-quote shell patterns containing $ metavariables. Use --debug-query with cst, ast, or pattern when parsing is unclear. See the rule and CLI reference for syntax and examples.
