Grit›Grit› offers GritQL

GritQL is a declarative query language for searching and modifying source code, built by Grit. Any code snippet functions as a valid query, and metavariables compose match-and-rewrite rules with automatic fixes. The Rust-based engine and query optimization are designed for repositories with more than ten million lines of code.

The language targets JavaScript, TypeScript, Python, Java, Terraform, Solidity, CSS, Markdown, YAML, Rust, Go, and SQL, and ships with a module system providing more than two hundred standard patterns. It is distributed through the Grit command-line interface, with documentation covering continuous-integration use, Visual Studio Code integration, and pattern sharing. Stated use cases include large-scale migrations, custom linting, code quality improvement, and dependency upgrades.
