emacs: good at lots of things, bad at displaying really long lines
@cwebber Is there any editor that's good at that?
@cwebber Ah, so you were talking about technical aspects and there I was thinking about how do I quickly get to a particular location (column) in that line. BTW, 10k is a *very* long line...
@mkwadee not when you're printing a lot of generated output at a REPL which doesn't pretty-print by default :)
@mkwadee well, some are better than emacs
by display I actually don't mean the UX of the visual rendering, I mean that if you have a line 10k+ characters long, emacs will start to choke on its display rendering code.
The reason for this, it turns out, is algorithm choice: gap buffers aren't good at this https://emacs.stackexchange.com/questions/598/how-do-i-prevent-extremely-long-lines-making-emacs-slow
