katana 是一个纯 C 语言实现的 CSS 解析器。

Katana is inspired by Gumbo, so it has some goals and features same as Gumbo.

Goals & features:

  • Simple API that can be easily wrapped by other languages.
  • Relatively lightweight, with no outside dependencies.
  • Support for fragment parsing.

Non-goals:

  • Mutability. Katana is intentionally designed to turn a style sheet into a parse tree, and free that parse tree all at once. It's not designed to persistently store nodes or subtrees outside of the parse tree, or to perform arbitrary style mutations within your program. If you need this functionality, we recommend translating the Katana parse tree into a mutable style representation more suited for the particular needs of your program before operating on it.

Wishlist:

  • Fully conformant with the CSS-syntax.
  • Hackable dump or print.
  • Robust and resilient to bad input.
  • Full-featured error reporting.
  • Additional performance improvements.
  • Tested on Official W3C Test Suites.

示例代码:

#include "katana.h" int main() {  const char* css = "selector { property: value }";  KatanaOutput* output = katana_parse(css, strlen(css), KatanaParserModeStylesheet);  // Do stuff with output, eg. print the input style  katana_dump_output(output);  katana_destroy_output(output);}
