I feel stupid for asking this, but I Googled and found nothing, checked classes for comments and found nothing, then skimmed Pharo by Example and also found nothing. Lukas mentioned helpfully in another thread that you can use the regex refactoring tools in the OmniBrowser to transform code, but I can't seem to figure out how to do it. I figured out how to "scope" the refactoring to a class or class hierarchy, which results in a gold window popping up with the selected class(es) in the left-most panel. When I right-click on the class at the top and choose "refactor->source regex", I get a template in the code panel that looks like this: ORSourceRegexRefactoring new "Example 1: Replace symbols with strings" replace: '#(\w+)' with: '''$1''' ignoreCase: false; "Example 2: Replace 4 spaces with tabs" replace: ' ' with: ' ' ignoreCase: false; yourself I wanted to rename a method (and all senders of it in the selected scope) from "nextValue" to "nextItem", so I edit the template to this: ORSourceRegexRefactoring new replace: 'nextValue' with: 'nextItem' ignoreCase: false; yourself I highlight it all with Alt-a, then Do It with Alt-d, but nothing seems to happen.
