查找以撇号或双斜杠开头的代码注释的正则表达式模式是什么？

Question

I'm trying to write a language definition for prismjs that will highlight Xojo code.

Comments in Xojo can be any of the following:

' A comment
// Another comment
rem A third comment

Comments can be inline, that is the following is valid:

dim a As Integer // still a comment

There are no multiline comments.

So far I have figured out how to highlight comments starting with the apostrophe using this regex pattern:

/'.*/

but I can't figure out the other two. Could anybody help?

Thanks,

Answer 1

这应该可以解决问题：

/('|\/\/|\brem\b).*/

Answer 2

Use a look behind:

/(?<=\/\/|'|\brem ).*/

See live demo .

This matches the comment (not the delimiter).
