如何在emacs中打印所有定义的变量？ [英] How to print all the defined variables in emacs?

问题描述

M-x < TAB>打印所有定义的功能。

要检查变量是否定义或不评估以下表达式，
（boundp'variable-name）Cx Ce将打印t如果变量名称为

解决方案

目前尚不清楚您想要完整的符号列表，但由于 Mx 显示函数名称的方式有些专门。

假设您想以编程方式获取所有已定义符号的列表，请执行以下操作： auto-complete.el >

 （循环为x为符号
 if（boundp x）
 collect（symbol-name x））
  

请注意，您还可以输入 Mx describe-var RET ，然后按 TAB 获得所有符号的排序完成列表。

M-x < TAB > prints all the defined functions.

To check a variable is defined or not evaluating the following expression, (boundp 'variable-name) C-x C-e will print t if the variable-name is defined else nill.

How to print all the defined variables in emacs.

解决方案

It's unclear exactly what you want to do with a full list of symbols, since the way in which M-x displays function names is somewhat specialized.

Assuming that you want to programmatically obtain a list of all defined symbols, here's how auto-complete.el does it:

(loop for x being the symbols
    if (boundp x)
    collect (symbol-name x))

Note that you can also enter M-x describe-var RET, and then press TAB to get a sorted completion list of all symbols.
