[Macdoku-developers] Update

[bob <kr...@ma...>]

Hi, all.

Well, I have undo/redo working just today.  However, I touched so  
much of the code that I feel the need to double check a lot.  Grid  
and Command are much different.  Also, I left the right-hand drawer  
in (for displaying the moves made in the future) but disabled the  
button to open it since it is not being included in the next  
release.  I removed the 'trace' command from the 'Control' menu and  
added (for us) option+d to dump the undo/redo stacks, option+t which  
toggles trace and option+1 which sets up a default game and turns on  
trace.  For testing purposes, I needed a game that I had already  
confirmed the possibles for and could give me a consistent starting  
point every time.  I did not figure that we would document those  
keystrokes.

Just wanted you to know that I am still working on this, but getting  
closer.  I should be able to save to svn early next week.

We may have to discuss putting some restrictions on the game or the  
undo/redo process.  For instance, I currently do not handle the  
situation where a user might turn off the 'view possibilities', do  
some moves and then turn on the 'view possibilities'.  I was thinking  
that we might want to restrict that to before the first move only.   
Anyway, it is a complication.  You will see what I mean when I  
produce the code, because an undo now stacks not only the new and  
prior guesses but also all the possibility additions/deletions.   
Anyway, it is something to keep in mind and maybe there is a good  
solution to the problem.

Last, I might add that my wife doesn't want all the fancy features.   
She likes the current version( the one that you have).  She says that  
some of the additions make playing the game too easy.  I must admit  
that the 's' (singleton) move has speeded up dramatically the few  
games that I have been playing.  However, she did agree with the  
multi-document approach that we might add in the next release.  She  
is very good at game play (freecell, spider solitaire, crossword  
puzzles, etc)!  So, I value her opinion.  (She has been playing  
several games a day and likes the fact that we are displaying the  
possibilities.  She also liked the 'new empty' and lock button for  
entering a new game.)
