Question

I am looking to match strings out of a file that are prefixed

/**

and have a postfix

*/

With any number of characters/whitespace/newlines in between.

eg:

/** anything
    anything
*/

I have m/(\/\*\*).*?(\*\/)/ so far, however this does not handle newlines. I know the fix has to be simple, but i have very limited regular expressions experience.
Bonus question: Does anyone have a good website for learning regular expressions?

Answer 1

Add the s modifier after it:

m/(\/\*\*).*?(\*\/)/s

But if it’s source code you’re operating on, be careful:

print 'a string /**';
int a = b + c;
print '*/';

// /**
a = a - c;
// */

There really is but one online resource if it comes to learning regex: http://www.regular-expressions.info/
