Re: change [A-Z] to U, [a-z] to L with one regex?

in reply to change [A-Z] to U, [a-z] to L with one regex?

You can always use $_:

$_ = "SomEThingWithMIXEDRegiSter\n";

y/A-Z/U/, y/a-z/L/;

print;

Yes, this is technically still two expressions, but as others have stated, it'll be efficient, and to me, anyway, the comma operator has good semantic meaning, here, even though a semicolon would do just as well.

Update: Corrected bracket typo in y///. Thanks jwkrahn.

[jwkrahn]

y/[A-Z]/U/, y/[a-z]/L/;

Doctrin didn't ask to change the characters [ or ] to U or L

y/A-Z/U/, y/a-z/L/;
