[Lazarus] LineRange [Re: Auto indentation]

[Martin]

Mattias,

have you looked at using
  StartLine := Min(Old:ogCaret.Y, LogCaret.Y);
  EndLine := Max(Old:ogCaret.Y, LogCaret.Y);


That would also have the advantage that an "end" would be unindented 
correctly. e.g typing

if a > 1 then begin
  b:= 1; // the indenter has added 2 spaces => correct
  end;|

now hit return at "|".
The line with the end in it does not change, so it is not in the range. 
But it is in the caret range. And it should be unindented
