改变Emacs前进行为 [英] Changing Emacs Forward-Word Behaviour

问题描述

如标题所示，如何改变emacs前进字功能的行为？例如，假设[]是光标。然后：

 我的$ abs_target_path [] = abs_path（$ target）; 
< M-f> 
我的$ abs_target_path = abs [_] path（$ target）; 
  

我知道我可以使用Mf Mb，但就我而言，不应该有必要，我想改变它。特别是，我想要两件事：

1. 当我按Mf时，我想去下一个字的第一个字符，无论是否该点在一个单词内，一组空格或其他地方。


2. 逐个模式地自定义字符。毕竟，在CPerl模式下移动不同于TeX模式。

所以，在上面的例子中，项目1将在点击Mf后，光标将移动到a（并指向左侧）。项目2将允许我将下划线和标语定义为字符。

解决方案

尝试：

 （require'misc）
  

然后使用 Mx转发单词，看看它是否执行你想要的。然后，您可以重新绑定 Mf 等。

要使 _ 不是一个单词分隔符（即使它成为一个单词成分）C& C ++模式，你可以这样做：

 （modify-syntax-entry？_wc-mode-syntax-table ）
（modify-syntax-entry？_wc ++  -  mode-syntax-table）
  

有关语法表的更多信息，请阅读此维基页面。语法表通常命名为 tex-mode-syntax-table 和 cperl-mode-syntax-table 。 p>

As the title says, how does one change the behaviour of emacs forward-word function? For example, suppose [] is the cursor. Then:

my $abs_target_path[]= abs_path($target);
<M-f>
my $abs_target_path = abs[_]path($target);

I know I could just use M-f M-b but as far as I'm concerned, that shouldn't be necessary and I'd like to change it. In particular, I want two things:

1. When I press M-f, I want to go to the first character of the next word regardless of whether the point is within a word, within a group of spaces or somewhere else.
2. Customize word-characters on a mode-by-mode basis. After all, moving around in CPerl mode is different than, say, TeX mode.

So, in the above example, item 1 would have the cursor would move to the 'a' (and the point to it's left) after hitting M-f. Item 2 would allow me to define underscores and sigils as word characters.

解决方案

Try:

(require 'misc)

Then use M-x forward-to-word and see if it does what you want. You can then rebind M-f, etc.

To make the _ not a word separator (i.e. make it a word constituent) for C & C++ mode, you would do this:

(modify-syntax-entry ?_ "w" c-mode-syntax-table)
(modify-syntax-entry ?_ "w" c++-mode-syntax-table)
