Introdução ao calcul-lisp-indent
Uma solução melhor é substituir a função calculate-lisp-indent. Em resumo, calculate-lisp-indenté uma função que retorna a coluna à qual uma linha no ponto deve ser recuada. Esta função é o que informa lisp-indent-functionquanto cada linha deve ser recuada. (veja também meu post no reddit para mais informações).
Comparação com outras respostas
A vantagem que esta resposta tem sobre o uso da função modificada do Fuco1 é que (1) corrige a raiz do problema que está em calculate-lisp-indentvez de apenas limpar após o recuo incorreto retornado por calculate-lisp-indent(2) generaliza para listas citadas e citadas (e funciona se eles são citados / citados explicitamente ou com o 'e `). Também funciona com aspas e aspas aninhadas arbitrariamente.
A vantagem que essa resposta tem sobre a substituição lisp-indent-functionpela common-lisp-indent-functionfunção é que ela não tem o efeito colateral de atrapalhar outro recuo do elisp. Elisp e common-lisp são recuados de maneira diferente.
Como funciona
Esse condicional (in calculate-lisp-indent) é o que decide se um sexp é recuado como uma função ou não. O que se encaixa na outra cláusula é recuado como uma função. O que se enquadra na cláusula if if é recuado normalmente (no elemento atual). Para fazê-lo recuar listas entre aspas como dados e não como funções, precisamos adicionar mais verificações nos casos em que a lista é citada no predicado condicional.
(if (= (point) calculate-lisp-indent-last-sexp)
;; Containing sexp has nothing before this line
;; except the first element. Indent under that element.
nil
;; Skip the first element, find start of second (the first
;; argument of the function call) and indent under.
(progn (forward-sexp 1)
(parse-partial-sexp (point)
calculate-lisp-indent-last-sexp
0 t)))
Esse código verifica os parênteses abertos do sexp que está sendo recuado. Se for sexp com vários sexp, ele verifica todos. Retorna t se encontrar algum sexps entre aspas ou com aspas.
(let* ((positions (elt state 9))
(last (car (last positions)))
(rest (nreverse (butlast positions)))
(any-quoted-p nil)
(point nil))
(or
(when-let (char last)
(or (char-equal char ?')
(char-equal char ?`)))
(while (and rest (not any-quoted-p))
(setq point (pop rest))
(setq any-quoted-p
(or
(when-let (char point)
(or (char-equal char ?')
(char-equal char ?`)))
(save-excursion
(goto-char (1+ point))
(looking-at-p "\\(?:back\\)?quote[\t\n\f\s]+(")))))))
Bônus
Se você deseja que qualquer lista que comece com uma palavra-chave seja recuada como dados, mesmo que não esteja entre aspas, adicione-a como outra verificação ao predicado condicional. Isso pode ser útil para macros nas quais as listas não são citadas por conveniência, como no defhydra .
(when-let (char-after (char-after (1+ containing-sexp)))
(char-equal char-after ?:))
Exemplos
O snippet de código completo que publiquei abaixo funciona com o caso que você mencionou e muito mais. Por favor, experimente!
;; Your example

Vale a pena notar que essa questão seria melhor generalizada como como impedir o emacs de recuar listas citadas e não citadas como funções .
