Why does lisp-interaction-mode exist, and do we ever need it?

Q: Why does lisp-interaction-mode exist, and are there any reasons to use it instead of emacs-lisp-mode? The manual states that emacs-lisp-mode and lisp-interaction-mode are identical except that the latter binds C-j to eval-print-last-sexp. Beyond…

How to change lisp mode indentation style

I'm not a lisp programmer. But I'm an emacs user, so I use elisp from times to times to do simple scripting. I'm not familiar with lisp style and I'm quite incompatible with it. Default indents quickly become over 80 whitespaces long making the…

Adjusting indenting for lisp if statements

I am learning common lisp and am trying to follow the style guide suggested by lisp-lang.org. In this style guide is an if statement style that I think makes the code more readable: (if (cond) (true-branch) (false-branch)) That is, the…

Dead keys not working in Emacs-Lisp mode *only*

I've been having a really annoying bug when editing elisp files recently: dead keys do not work, but only when I am in Emacs-Lisp mode. If I type a key that is configured as a dead key (say, '), I get a prompt that says Emacs-Lisp: on my mini…

I saw a teacher in iTunes U doing this: have 2 windows open in Emacs, the top is the Scheme (or Lisp) source code, and the bottom is the Scheme interpreter. He seems to press something on the keyboard and the whole Scheme statement will be copied…

Change indent for function calls in Emacs Lisp?

While writing the question I found a viable workaround solution for myself, so I am posting it as Q&A. I am leaving the question open, because my workaround does not allow to set the amount by which things are indented. By default Emacs indents…

Emacs-Lisp mode indentation problem when doc string contains left parenthesis in first column

Usually when I write Lisp code (in an Emacs-Lisp mode buffer), I can press TAB (bound to indent-for-tab-command) to indent code properly. However, if I write a defun with a docstring (longer than one line) that also contains a left parenthesis (in…
