本文讨论了在使用Emacs编辑器进行Ruby编程时遇到的字符串插值问题，并提供了一个临时解决方案来修复Ruby-electric-brace函数的异常行为。

2019独角兽企业重金招聘Python工程师标准>>>

Ruby uses the syntax "... #{_expression_}..." for string interpolation. But when I press left curly brace, Emacs says "Symbol's value as variable is void: last-command-char".

I C-h k {, and saw that { and } are bound to ruby-electric-brace. This function appears to be malfunctioning.

As a workaround, I M-x fundamental-mode, typed a literal { and }, then M-x ruby-mode. Doing this repeatedly became a hassle, so I added a temporary hook to my .emacs:

(add-hook 'ruby-mode-hook

(lambda ()

(define-key ruby-mode-map "{" nil)

(define-key ruby-mode-map "}" nil)))
