如何隐藏Emacs的“过时变量”警告？ [英] How do I hide Emacs' "obsolete variable" warnings?

问题描述

我已经升级到Emacs 23.3，现在的 * Compile-Log * 缓冲区不断打开，错误如下：

I've upgraded to Emacs 23.3 and now the *Compile-Log* buffer opens constantly with errors like:

Warning: `font-lock-beginning-of-syntax-function' is an obsolete variable (as
    of Emacs 23.3); use `syntax-begin-function' instead.

我假设上游作者将来会处理这些警告。在此之前，我如何防止这些错误出现并打开一个新窗口？

I'm assuming the upstream authors will take care of these warnings in the future. Until then, how can I prevent these errors from appearing and opening a new window?

推荐答案

我现在回到23.2到另一个问题，但是当我在尝试23.3时，我已经为这个问题提供了一个解决方法。它只是防止变量被认为是过时的，但是直到Mumamo排序出来，这似乎更为可取。

I'm currently back on 23.2 due to another issue, but I hacked a workaround for this issue while I was trying 23.3. It simply prevents the variable from being considered obsolete, but until Mumamo sorts itself out, that seemed preferable!

;; Mumamo is making emacs 23.3 freak out:
(when (and (equal emacs-major-version 23)
           (equal emacs-minor-version 3))
  (eval-after-load "bytecomp"
    '(add-to-list 'byte-compile-not-obsolete-vars
                  'font-lock-beginning-of-syntax-function))
  ;; tramp-compat.el clobbers this variable!
  (eval-after-load "tramp-compat"
    '(add-to-list 'byte-compile-not-obsolete-vars
                  'font-lock-beginning-of-syntax-function)))
