In UltraEdit for Mac, I want to replace group0(full match) with group0 plus some more

Question

I'm using UltraEdit in Perl regex mode to do that. i.e. (cat) (dog) replaced with $0\n$1 $2

Although the $1 and $2 worked, I couldn't find a way to make $0 work.

Does anyone experience this issue?

Answer 1

When using "Perl" regular expressions in Ultra Edit,

• $& contains the matched text.
• $` contains the portion of the document leading up to the matched text.
• $' contains the portion of the document following the matched text.

This is documented here. (Scroll down to "Perl regex output modifiers".)

This is consistent with Perl, where $0 contains the first argument to the program (the name of the program).
