Marcin Borkowski – Apparently, my last blog post about diffing buffer fragments sparked a small discussion on Twitter. Most comments fell into one of two categories: some people wanted to use ediff (which I explicitly mentioned I didn’t want), and some people complained about the temp files (which do not bother me that much). Well, it turns out that I really did not have to create the temp files after all!

We all know and love diff, but it operates on files, and what I had was two fragments of two files (or sometimes even of one file) which I wanted to compare. There are a few solutions to this problem, but they seemed too complicated for me.

• 20:12 UTC (new) (history) 2019-11-04 Starting Emacs with custom configuration directory . . . . Marcin Borkowski – The usual thing people are told to do when debugging/isolating Emacs problems is to say emacs -Q, that is, start Emacs without reading in any configuration. Sometimes, however, this may not be a good idea. When there is some problem with packages, however, we may actually want to load some things, like a minimal set of packages if we suspect they do not work together. Of course, what we don’t want is changing our configuration.

• 18:59 UTC (new) (history) 2019-10-21 Clearing the Eshell buffer . . . . Marcin Borkowski – Since I’ve been quite busy recently, I only have one short tip today. I sometimes use Eshell, and sometimes want to clear it so that I can e.g. isearch through the result of running some command and not be bothered by the output of previous commands. In such a case, I can say clear, but it does not really clear the Eshell buffer – it only makes the part above point scroll past the visible part (and it seems that it doesn’t even take into account the font – if I make it smaller, clear does not scroll enough). But I can also give clear any argument (e.g., say clear t), and then the previous contents of the buffer are really deleted. Handy.
