matlab - Emacs 缓冲区撤消限制

Question

当我大量打印到标准输出时，我在 matlab-shell 缓冲区中收到此警告:

Warning (undo): Buffer `*MATLAB*' undo info was 12268000 bytes long.
The undo info was discarded because it exceeded `undo-outer-limit'.

This is normal if you executed a command that made a huge change
to the buffer.  In that case, to prevent similar problems in the
future, set `undo-outer-limit' to a value that is large enough to
cover the maximum size of normal changes you expect a single
command to make, but not so large that it might exceed the
maximum memory allotted to Emacs.

我的 emacs 看起来像这样:

我真的不需要在 matlab-shell 中进行任何撤消操作，这是正确的缓冲区。有没有办法禁用此警告？请注意，左侧缓冲区是一个 MATLAB 脚本，这意味着主要模式是 MATLAB，当然不应在此处禁用撤消。

Answer 1

正如该警告消息所说(或曾经说过？):

You can disable the popping up of this buffer by adding the entry (undo discard-info) to the user option warning-suppress-types, which is defined in the warnings library.

即:

(add-to-list 'warning-suppress-types '(undo discard-info))

(这当然只会禁用警告，而不是撤消数据收集本身。)
