Dear Simon, dear all,
here is my tiny suggestion to improve the undo behaviour in R's
console after auto-pairing "" () etc.:
In RTextView.m around line 208 (Mac-GUI-1.27):
case '\'':
if (!complement) {
complement = @"\'";
acCheck = YES;
if ([self parserContextForPosition:r.location] != pcExpression)
break;
}
// register the next pairing procedure to the undo manager better
[self shouldChangeTextInRange:[self selectedRange]
replacementString:complement];
SLog(@"RTextView: open bracket chracter %c", ck);
[super keyDown:theEvent];
{
r = [self selectedRange];
if (r.location != NSNotFound) {
[self shouldChangeTextInRange:[self selectedRange]
replacementString:complement];
will register the next changes a bit better.
The return value of that function is ignored but it could be used as:
if([self shouldChangeTextInRange:[self selectedRange]
replacementString:complement])
... do it
else
... print error - not editable
Cheers,
--Hans
