改变 Emacs 转发行为 [英] Changing Emacs Forward-Word Behaviour

问题描述

正如标题所说，如何改变 emacs forward-word 函数的行为?例如，假设 [] 是光标.然后:

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);

我知道我可以只使用 M-f M-b 但就我而言，这应该没有必要，我想更改它.特别是，我想要两件事:

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. 当我按 M-f 时，我想转到下一个单词的第一个字符，无论该点是在一个单词内、一组空格内还是其他地方.
2. 逐个模式自定义单词字符.毕竟，在 CPerl 模式下移动不同于 TeX 模式.

因此，在上面的示例中，项目 1 将使光标在点击 M-f 后移动到 'a'(及其左侧的点).第 2 项允许我将下划线和符号定义为单词字符.

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.

推荐答案

尝试:

(require 'misc)

然后使用 M-x forward-to-word 看看它是否符合您的要求.然后你可以重新绑定M-f等

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

为了使 _ 不是 C & 的单词分隔符(即使其成为单词组成部分)C++ 模式，你会这样做:

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)
