let string = "Regex to find URLs unless they include a list of strings (Visual Studio search)
I have this the following expression which is working well for my needs:
(www\\.)?[-a-zA-Z0-9@:%._\\+~#=]{2,256}\\.(com|net|info)\\b([-a-zA-Z0-9@:%_\\+.~#?&//=]*)
It does a pretty good job of finding URLs which are hardcoded in a large codebase. Obviously, it has some false positives for things like Using System.net, but some of the valid URLs don't include http(s):// unfortunately.
So now I want to be able to exclude certain things, including system.net (false positives) and google.com (common urls in comments).
How can I do this?
Ideally the list would just include google and system. Something like (!google|!system).
https://thisisaurl.com/";
// result will be an iterator over tuples containing the start and end indices for each match in the string
let result = regex.captures_iter(string);
for mat in result {
println!("{:?}", mat);
}
}
