I was just looking after the same problem.
Thanks for the fix. I've just submitted it.


ps: if your editor reformat the sources then patches are unusable. you have to disable reformatting when working on texmacs code.

HI all,

  I've been experiencing a bug with the svn version of the code for some time. Pressing the "apostrophe" key ( ), the one needed to produce letters like , caused the program to crash apparently after a random number of times. The console showed pairs of

-[NSCFString characterAtIndex:]: Range or index out of bounds

and a, to my eyes, utterly undecipherable stack trace. It took me an embarrassing amount of time to think of searching for "characterAtIndex" and thus locate the problem in Plugins/MacOS/mac_utilities.mm, function mac_handler_body, around line 76. The new first few lines of it must check for empty strings:

NSEvent *mac_handler_body(NSEvent *event


  if (([event type] == NSKeyDown) || ([event type] == NSKeyUp)) {

    NSString *nss = [event charactersIgnoringModifiers];

    if ([nss length] > 0) {

      unichar key = [nss characterAtIndex:0];

and then a new closing brace must be added, of course. I have attached a diff for that file only, but my editor has messed up the indentation so it looks bigger than it is.

Best regards,
Miguel de  Benito.
