Thanks very much, that worked great!

I am newbie and I am trying to understand everything that is going on in your expression.

Can you please help me understand what is happening between these two expressions?

^ beginning of the line

.*::.*

$ end of the line

also…

can you please tell me what the zero after the $ doing in this string?

getValue( $0; 1) ;

The expression is ^.*::.*$

To learn more about RegEx, I can recommend Regexr.com http://regexr.com/3coa1 (with your case http://regexr.com/3coa1). It is based on the JavaScript implementation, so there are limits, but it's a good start.

As Carpii said, you define “capture groups” with parentheses. TextMate Find & Replace behaves like PHP's preg_match http://php.net/manual/en/function.preg-match.php, so the “entire match” is in |$0|. In this case you need the entire line unbroken, so that's why |$0| works.

If instead you want to change:

|PRODUCTS 2::prnt_material_width |

to

|getValue( PRODUCTS 2 ; prnt_material_width ; 1) ;|

You would need to match the two groups separately:

|^(.+)::(.+)$|

Replace with:

|getValue( $1 ; $2 ; 1) ;|

I use |+| instead of |*|, because |+| requires a minimum of 1 character. It's a habit.

And of course there are many practical applications to knowing regular expressions http://xkcd.com/208.

$  end of the line

^ match the beginning of the line

.* followed by 0 or more characters (apart from newline)

:: followed by 2 literal colon characters

.* followed by 0 or more characters (apart from newline)

$ followed by the end of the line (a \n character)

The $0 is a way of referencing one of the captures the regular expression made I'm not entirely sure this capturing syntax is right, normally I use brackets to capture, yet it seems to work in textmate.

We need to do this otherwise we don't know what to output after getValue(

Thanks very much guys for the explanation and the RegEx links.

I really appreciate it.
