What it does

ast-grep is a AST-based tool to search code by pattern code. Think it as your old-friend grep but it matches AST nodes instead of text. You can write patterns as if you are writing ordinary code. It will match all code that has the same syntactical structure. You can use $ sign + upper case letters as wildcard, e.g. $MATCH, to match any single AST node. Think it as REGEX dot ., except it is not textual.
