好吧,事实证明这比预期的要难得多,而且这可能是个坏主意。我们真正需要的是将 Pod::Elemental 文档转换为 (X)HTML(5) 的新实用程序,与 Pod::Simple::(X)HTML 兼容(这样我们就可以继续使用旧的 CSS 样式)。如果有人写/找到合适的模块并在此处发布,我将接受另一个答案。
所以这就是我所做的。我必须将POD::Simple::Search=method
子类化,因为它使用不包括与 Pod::Weaver 一起使用的内容的正则表达式检查 POD 文件。对于每个文件,我必须创建一个 PPI 文档并删除 POD,然后将 POD 连接起来并将其制成 Pod::Elemental 文档。这就是在 Pod::Elemental::PerlMunger 中完成的,这也是 Dist::Zilla 使用的。
