Find/Replace with Regular Expressions and Match Evaluators

This Eclipse plugin enhances any editor in Eclipse with a Find/Replace dialog that can be brought up with Ctrl + F5.

Compared to the standard Find/Replace dialog in Eclipse, you have the option to replace Regular Expression matches with so-called Match Evaluators.

E.g. suppose you coded a user interface and wanted to move a bunch of controls inside a GridLayout one row down, i.e. replace Row="5" with Row="6" and replace Row="100" with Row="101".

Then search for the Regular Expression (?<=Row=")(\d+) and use the following Match Evaluator to replace those matches:

Function<MatchResult, String> matchEvaluator = new Function<MatchResult, String>(){

@Override

public String apply(MatchResult match){

int i = Integer.parseInt( match.group(1) );

return "" + (i+1);

}

};
