Topiary is a universal code formatter that leverages Tree-sitter grammars to apply consistent styling without requiring language-specific implementation logic. It is particularly effective for formatting configuration files (JSON, TOML), shell scripts (Bash), and niche languages (Nickel, OCaml) where dedicated formatters may be unavailable. By using declarative S-expression query files (.scm), developers can define precise rules for indentation, spacing, and line breaks, ensuring that code remains clean and version-control friendly across diverse development environments and CI/CD pipelines.
