19:05 UTC (new) (history) 2016-12-04 Making C-c C-j in AUCTeX do something more useful . . . . Marcin Borkowski – In AUCTeX’s LaTeX mode, C-c C-j is by default bound to LaTeX-insert-item. By default, it just inserts an \item on a new line. I thought that it would be cool to make it insert something else in non-itemize environments. It turns out that I was late, though – the functionality is already there! It is not widely known, however; in particular, it’s not mentioned in the manual.

It would get a string with embedded “control codes”, like %t% or %h, and then output a string with these “control codes” replaced by actual content. Writing something like that is not particularly difficult, but since I wanted to be able to also escape the percent sign by writing %%, I didn’t really feel like reinventing the wheel (and doing it elegantly and efficiently might be a tad tricky anyway). I asked a question on the help-gnu-emacs mailing list, and voilà! Here is the format-spec function.

18:54 UTC (new) (history) 2016-11-13 debug-on-entry . . . . Marcin Borkowski – Some time ago, I had a very strange problem. I was writing a certain library for Emacs, and in one of the functions I had a Mark set message coming apparently out of nowhere. Since my function used timers, closures and callbacks to do things asynchronously, edebug didn’t help me a lot. Happily, I knew what can give such a message: push-mark. (BTW, this is yet another good reason to have Emacs sources handy: if I hadn’t known that, I could have just grepped the sources.) Now, finding the offending push-mark was a question of five seconds:
