Golang正则表达式以查找字符串中的网址

Question

I am tring to find all links in a string and then hyperlink them
like this js lib https://github.com/bryanwoods/autolink-js

i tried to use alot of regex but i always got too many errors
http://play.golang.org/p/iQiccXvFiB
i don't know if go has a different regex syntax

so, what regex that works in go that is good to match urls in strings

thanks

Answer 1

Use back-ticks instead of double-quotes for your string literals. Back-slashes inside double-quotes start escape sequences, which you don't need/want for this use case.

Additionally, how did you expect this to work?

"<a href="$0">$0</a>"
