[−][src]Crate prettify_js
prettify-js is a tokenizer-based JS prettyprinter that generates source maps.
Example:
let (pretty, _) = prettify_js::prettyprint("function x(a){return a;}"); assert_eq!(pretty, "function x(a) {\n return a;\n}\n");
Structs
SourceCoord | Source coordinate, line+column |
SourceMapColumn | Zero-based column number, in UTF16 code units |
SourceMapLine | Zero-based line number |
SourceMapping | Points that correspond in the original/generated source code. |
Functions
generate_source_map | Generate a source-map as a string, given the original source file name, file data, and a list of mappings from the original source to the generated source. |
maybe_prettyprint | Convenience function to create a sourcemap for the prettyprinted version of the file (if it needs prettyprinting), generate a URL for it and append that URL to the file text so it gets used. |
prettyprint | Prettyprint JS source code. Returns the prettyprinted code, plus a list of SourceMappings in source order (both in original and prettyprinted code ... we don't reorder code). |
should_prettyprint | Uses a heuristic to decide if the source file needs prettyprinting: whether its average line length is > 100. |
