UNDO lots of stuff in one go -- defining undoable composite operations [message #289107]

Hi,

I'm implementing a refactoring tool for a custom editor. Currently I
locate all references to a certain variable and use document.replace()
to change the variable name. However, when I try to undo I have to undo
many times to completely undo the entire refactoring rename operation.

Instead I would like the undo menu to say "Undo rename variable" and
when clicked I would like it to change ALL the variable names back in
one go. Is this possible?

regards,
martin

There are so many ways to do it. Just take a look at the different undo
classes (e.g., undomanager).
You can also look at the HippieCompletionAction class (in the
org.eclipse...texteditor plugin).
