SES has two zones in the buffer. - print area is what you see data area is where the document object is - stored The document object is a vector of cell objects + a few parameters (column count/width, cell width, local printers), each cell object is also implemented as a vector. IMHO what really needs to be atomic --- otherwise recovery is jeopardized : 1) keep correct the number of lines in the print area --- if you don't have that, locating the data area is jeopardized 2) keep correct the cell widths in the print area, and cell intangible property --- otherwise the print-area point to cell id is broken 3) any update of the data area. Just reading the code I found one place where this was not observed, and I just made a correction --- see http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=c1b180153f57777b64e27c45633d8a05e02dda5a There are surely a number of other ones which I still need to spot and fix. FYI cell calculation + update of the print area on the one hand is deferred with the list ses--deferred-recalc, and update of the data area is also deferred with the list ses--deferred-write, so inherently there is a risk when you quit to drop the deferred operations and make the cell values inconsistent with the result that calculations would otherwise have, or to break the reference lists, or to make the printed cell values inconsistent with the actual cell values in the document object, or to make the data area inconsistent with the document object. In the latter case (document object inconsistent with data area), reconstructing all will overwrite document object by what is read from data area, loosing your latest edits. Similarly saving the document will not update to consistency the data area, so if you save + close + reopen the file, that won't solve it. What really is needed is the « Dirty » indicator for the user to get warned, and not go on editing a document while there are such inconsistency. This is especially true for inconsistency between document object and data area. I need to fix that, when I am done with remaining bugs in cell renaming. Vincent.

This is a while ago for me, but I arrived at it only from the formula
eval part.
No doubt storing data and formatted etc should be atomic. I hoped only
that perhaps those could otherwise be in a consistent state when a
particular formula is evalled, so quit out of something wild is ok.
It would leave some or all recalculates still needed of course.

Yes, I think that'd be very nice.

My understanding is that if you quit during modifying the formulas, then the SES object that under the hood holds all the inputs of the spreadsheet might get corrupt, and then it would be impossible to recover from that situation. However, since some processing (updating the cell values) might be quite lengthy, you want to be able to quit during that. Probably there should be some indicator in the mode bar that the referenes/values/ or display are « dirty », after some quit has occurred and until the user makes some repair cell reference all + recalculate all + redisplay all. Please note that : - the « repair cell reference » exists --- ses-repair-cell-reference-all --- this is one of the additions I did. - recalculate all exists --- ses-recalculate-all - but there is not redisplay-all as such, you need to call ses-reconstruct-all that will do all three operations, to my knonwledge there is no way if you just want to repair the display (for instance you have quitted during changing a column width, so the cells references and value are not broken, just the display is broken) FYI, Updating the cell value through the formulaes is made by post-command-hook, not during the editing of the formula by itself. Please not that when time allows, my intention was to add some commands to make some cell permutations (for instance row or column transposition). I have still not done that, because there are remaining bugs with the cell renaming, and I wish to solve that before. Also, quiting/undoing during cell renaming is probably not well supported. Anyway this discussion is certainly usefull as I have not yet thought how to handle quiting during such a permutation, and handling undoing of it --- idealy quitting would be possible, and undoing would undo only that part that have been done before the quit.
