Emacs预览-latex

Question

我使用LaTeX -LaTeX在Emacs窗口中显示预览结果。我使用预览点在代码和输出之间来回切换。但是，如果我不在Latex代码上(错误地，我可能差了一两行)，那么预览点尝试编译所有内容，打开"other“窗口，并失败。所有这些过程都会让事情变慢。

我的问题是如何禁用此编译(尝试)？如果不能进行切换，则预览不应执行任何操作。有预览latex的设置吗？或者是一个我可以覆盖的函数？

error in process sentinel: LaTeX found no preview images

谢谢,

真正的工作是由preview-region完成的，所以我们可以建议在某些情况下不要这样做。下面是不完美的，因为我认为没有办法提前知道要预览的内容-用户可以指定任何要预览的环境或宏。例如，如果您只关心数学预览，那么您可以删除previewable-environments片段。

(defvar previewable-environments
  "List of environments that should be previewed."
  '("tabular" "tabular*" "tikzpicture" "..."))

(defadvice preview-region (around preview-at-point-no-long-pauses activate)
  "Make `preview-at-point' a no-op if mark is inactive and point is not on a preview."
  (when (or (not (eq this-command 'preview-at-point))
            (TeX-active-mark)
            (texmathp)
            (member (LaTeX-current-environment) previewable-environments))
    ad-do-it))

接受答案的一个变体:如果代码在一个等式上，它将触发预览切换，但我也希望当我不在任何数学片段上时，可以预览整个文档。它的代码是

(defvar previewable-environments
  "List of environments that should be previewed."
  '("tabular" "tabular*" "tikzpicture" "..."))

(defadvice preview-region (around preview-at-point-no-long-pauses activate)
  "Make `preview-at-point' a no-op if mark is inactive and point is not on a preview."
  (message "preview-region")
  (if (or (not (eq this-command 'preview-at-point))
            (TeX-active-mark)
            (texmathp)
            (member (LaTeX-current-environment) previewable-environments))
    ad-do-it
    (preview-section)
    )
  )
