Question

我正在获得一个网络主机，我有团队合作项目。我认为让我自己的粘贴网站粘贴没有失效日期是个好主意（我知道 http：// pastie。 org / 存在）和其他事情。我想知道。什么是一个简单的亮点lib我可以在代码上使用？我只会使用C / C ++。

Answer 1

问题标记为<！>“; php <！>”;但你<！>;只会使用C / C ++ <！>;？

PHP解决方案是 GeSHi 。

仅为一种语言构建荧光笔（无上下文，使用常规词汇，如C ++）实际上非常简单，因为您基本上可以将所有词汇包装成一个大的正则表达式：

$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>";
}
