默认情况下如何获取C-x C-e以八进制和十六进制显示结果？ [英] How to get C-x C-e to display the result in octal and hexadecimal by default?

问题描述

当我第二次在数字表达式上按下 C-x C-e 时，迷你缓冲区以八进制和十六进制显示结果。记录在此处

When I hit C-x C-e on a numeric expression a second time, the mini-buffer displays the result in octal and hexadecimal. This is documented here

有没有办法在第一个 Cx Ce 上以十六进制和八进制形式获得结果？

Is there a way to get the result in hex and octal on the first C-x C-e?

推荐答案

您可以通过此建议获得该行为。请注意，我也将其用于 eval-print-last-sexp （又名 C-j ）。只需将其从列表中删除即可。

You can get that behavior with this advice. Note, I made it also work for eval-print-last-sexp (aka C-j). Just remove that from the list if you don't want that behavior.

(defadvice eval-expression-print-format (around eepf-tweak-output activate)
  "tweak output when this-command is eval-last-sexp or eval-print-last-sexp"
  (let ((last-command (if (memq this-command '(eval-last-sexp eval-print-last-sexp))
                          this-command
                        last-command)))
    ad-do-it))
