Website insertion, syntax highlighting

I am getting web hosting and I have projects with teammats. I thought it would be nice to have my own paste site that doesn't have a paste expiration date (I know http://pastie.org/ ) and other things. I wanted to know. What is a simple lib highlighting that I can use for code? I would only use C / C ++.

The question is marked as "php" but are you "only using C / C ++"?

Making a token for just one language (no context, with regexes like C ++) is actually pretty straightforward, because you can basically wrap all your tokens in one big regex:



$cpplex = '/
    (?<string>"(?:\\\\"|.)*?")|
    (?<char>\'(?:\\\\\'|.)*?\')|
    (?<comment>\\/\\/.*?\n|\\/\*.*?\*\\/)|
    (?<preprocessor>#\w+(?:\\\\\n|[^\\\\])*?\n)| # This one is not perfect!
    (?<number>
        (?: # Integer followed by optional fractional part.
            (?:0(?:
                    x[0-9a-f]+|[0-7]*)|\d+)
            (?:\.\d*)?(?:e[+-]\d+)?)
        |(?: # Just the fractional part.
            (?:\.\d*)(?:e[+-]\d+)?))|
    (?<keyword>asm|auto|break|case…)|            # TODO Complete. Include ciso646!
    (?<identifier>\\w(?:\\w|\\d)*)
    /xs';

$matches = preg_match_all($cpplex, $input, $matches, PREG_OFFSET_CAPTURE);

foreach ($matches as $match) {
    // TODO: determine which group was matched.
    // Don't forget lexemes that are *not* part of the expression:
    // i.e. whitespaces and operators. These are between the matches.
    echo "<span class=\"$keyword\">$token</span>";
}
