你能在 Vim 中有文件类型特定的键绑定吗? [英] Can you have file type-specific key bindings in Vim?

问题描述

在我的 .vimrc 文件中，我有一个用于注释的键绑定，它在行首插入双斜杠 (//):

In my .vimrc file, I have a key binding for commenting out that inserts double slashes (//) at the start of a line:

" the mappings below are for commenting blocks of text
:map <C-G> :s/^/\/\//<Esc><Esc>
:map <C-T> :s/\/\/// <Esc><Esc>

但是，当我编辑 Python 脚本时，我想将其更改为 # 符号以供评论

However, when I’m editing Python scripts, I want to change that to a # sign for comments

我的 .vim/ftdetect 文件夹中有一个 Python.vim 文件，该文件还具有选项卡宽度等设置.如果可能，覆盖键绑定的代码是什么，以便我使用 Python:

I have a Python.vim file in my .vim/ftdetect folder that also has settings for tab widths, etc. What is the code to override the keybindings if possible, so that I have Python use:

" the mappings below are for commenting blocks of text
:map <C-G> :s/^/#/<Esc><Esc>
:map <C-T> :s/#/ <Esc><Esc>

推荐答案

ftdetect 文件夹用于文件类型检测的脚本.文件类型插件必须在 ftplugin 文件夹内.文件类型必须以以下三种形式之一包含在文件名中:

The ftdetect folder is for scripts of filetype detection. Filetype plugins must be inside the ftplugin folder. The filetype must be included in the file name in one of the following three forms:

• .../ftplugin/.vim
• .../ftplugin/_foo.vim
• .../ftplugin//foo.vim

例如，您可以将 cpp 文件类型的注释映射到 .../ftplugin/cpp_mine.vim 中:

For instance, you can map comments for the cpp filetype putting the following inside the .../ftplugin/cpp_mine.vim:

:map <buffer> <C-G> :s/^/\/\//<Esc><Esc>
:map <buffer> <C-T> :s/\/\/// <Esc><Esc>
