通过重新编译抑制在 emacs 中保存文件的提示

Question

我通常设置一个重要的编译命令，然后频繁调用'recompile. 有没有办法抑制保存文件的提示，类似于 auctex 调用的方法(setq TeX-save-query nil)？我发现总是必须手动保存或按y提示按下非常烦人。当我点击重新编译时，我希望在必要时保存所有文件。

compilation-ask-about-save is a variable defined in `compile.el'.
Its value is t

Documentation:
Non-nil means M-x compile asks which buffers to save before compiling.
Otherwise, it saves all modified buffers without asking.

You can customize this variable.

这是函数recompile，它演示了它也使用变量compilation-ask-about-save：

compilation-ask-about-save is a variable defined in `compile.el'.
Its value is t

Documentation:
Non-nil means M-x compile asks which buffers to save before compiling.
Otherwise, it saves all modified buffers without asking.

You can customize this variable.

另请参阅文档字符串save-some-buffers：“可选参数（前缀）非 nil 意味着毫无疑问地保存所有内容。 ”

save-some-buffers is an interactive compiled Lisp function in
`files.el'.

It is bound to C-x s.

(save-some-buffers &optional ARG PRED)

Save some modified file-visiting buffers.  Asks user about each one.
You can answer `y' to save, `n' not to save, `C-r' to look at the
buffer in question with `view-buffer' before deciding or `d' to
view the differences using `diff-buffer-with-file'.

This command first saves any buffers where `buffer-save-without-query' is
non-nil, without asking.

Optional argument (the prefix) non-nil means save all with no questions.
Optional second argument PRED determines which buffers are considered:
If PRED is nil, all the file-visiting buffers are considered.
If PRED is t, then certain non-file buffers will also be considered.
If PRED is a zero-argument function, it indicates for each buffer whether
to consider it or not when called with that buffer current.

See `save-some-buffers-action-alist' if you want to
change the additional actions you can take on files.
