emacs中的ESS / Stata模式错误地缩进以运算符结尾的行后面的行。它似乎错误地将这些行解释为多行命令。
例如:
gen foo = 1
/* generate another variable */
gen bar = 1
“gen bar = 1”这一行不应缩进。看起来EMACS将注释中的尾部斜杠解释为运算符,并认为这行代码跨越两行。
实际上,stata中的多行命令有3个尾部斜杠,没有3个尾部斜杠的换行符表示语句结束。例如以下缩进是正确的:
gen bar = 1
gen ///
foo = 1
我可以在我的.emacs中添加一些内容来纠正这种行为吗?我不想完全放弃自动标签 - 除了/ *看起来像* /的评论之外,它的效果非常好。
谢谢,

你是对的,ESS将尾随/
解释为行继续的指示。这被硬编码到函数ess-continued-statement-p
中,因此要修改您必须重写代码的行为。以下代码(在您的.emacs
中)适用于您的示例。
(eval-after-load 'ess-mode
'(defun ess-continued-statement-p ()
"this is modified code"
(let ((eol (point)))
(save-excursion
(cond ((memq (preceding-char) '(nil ?\, ?\; ?\} ?\{ ?\]))
nil)
;; ((bolp))
((= (preceding-char) ?\))
(forward-sexp -2)
(looking-at "if\\b[ \t]*(\\|function\\b[ \t]*(\\|for\\b[ \t]*(\\|while\\b[ \t]*("))
((progn (forward-sexp -1)
(and (looking-at "else\\b\\|repeat\\b")
(not (looking-at "else\\s_\\|repeat\\s_"))))
(skip-chars-backward " \t")
(or (bolp)
(= (preceding-char) ?\;)))
(t
(progn (goto-char eol)
(skip-chars-backward " \t")
(or (and (> (current-column) 1)
(save-excursion (backward-char 1)
;;;; Modified code starts here: ;;;;
(or (looking-at "[-:+*><=]")
(and (looking-at "/")
(save-excursion (backward-char 1)
(not (looking-at "*")))))))
;;;; End of modified code ;;;;
(and (> (current-column) 3)
(progn (backward-char 3)
(looking-at "%[^ \t]%")))))))))))
