Recently I started using Emacs as my Scheme (Lisp) editor. I’m thinking what extensions should I use in order to achieve the best performance. Currently I’m using Paredit and it helps a lot. I know that there are numerous Scheme extensions for Emacs: Geiser, Quack to name the two that seem very popular, and EmacsWiki lists many more. Which of these have you guys used and which ones do you find the best? At the moment my biggest problem is lack of parentheses colouring, which makes it vary hard to pair them visually – indentations are not enough when you have a line of code ending with ))))))))
I’m also thinking how could I improve the keyboard layout of Emacs in order to do better in Scheme editing? I’ve found some good advice on CLiki. I swapped [] with () on the keyboard and that’s helpful. I’m also considering swapping Alt and Ctrl keys.
Do you have any other tips and suggestions that make it easier to edit Scheme in Emacs?
I’ve found rainbow delimiters mode really helpful for highlighting different levels of parentheses.
Among other modes that help me write lisp are hideshow mode for folding of sexps, slime which is primarily for Common Lisp but I use it’s indentation capabilities in scheme too, low-contrast color theme called solarized with which my eyes don’t fatigue any more and heavily mutated vim mode which permits me to keep my keybindings manageable through editing modes.
