svg-format

Structural formatter for SVG documents.

This crate formats SVG by parsing with tree-sitter and rebuilding a normalized structure with tab indentation, deterministic attribute ordering, and stable tag layout. Style/script text blocks are preserved without trying to parse and rewrite CSS/JS semantics.

    format,
    format_with_options,

};

let pretty = format(source);

let pretty_custom = format_with_options(

        insert_spaces: false,
        max_inline_tag_width: 100,
