An incremental [PEG](https://en.wikipedia.org/wiki/Parsing_expression_grammar)-based syntax highlighting engine written in C++.

```cpp

#include 

#include 

int main() {

    const StringInput input = "int main() { return 42; }";

    const Language* language = prism::get_language("file.c");

    Cache cache;

    auto spans = prism::highlight(language, &input, cache, 0, input.size());

    std::vector expected = {

        {0, 3, Style::TYPE},

        {13, 19, Style::KEYWORD},

        {20, 22, Style::LITERAL},

    };

    assert(spans == expected);

}

```
