多年后，我终于清理了我的.vimrc并深入研究了设置的确如此真实。我花了很多时间来修剪和阅读帮助文件。
现在我已经达到了一个非常小的.vimrc，我很满意 - 我相信我理解其中的每一件事（很多评论）。我将把我的.vimrc包含在这个问题的底部。
我的问题是，我正在使用Python（第一次），并且某种程度上vim有一堆设置（我不喜欢） - 看似内置。我怎么能：
注意：我删除了我的.viminfo文件（在备份之后）以清除所有内容。
当我打开python文件并输入old_handler = trap("INT") do
puts "doing something custom in response to INT"
if old_handler.respond_to?(:call)
puts "calling old handler for INT"
old_handler.call
exit # in case old_handler is a bad citizen
else
case old_handler
when "DEFAULT"
puts "done with custom handlers, exiting in response to INT"
exit
when "IGNORE"
puts "done with custom handlers for INT, system default ignores it"
else
# in the case of EXIT it is nil. Not sure of other possibilities
puts "old_handler is : #{old_handler.class}"
end
end
end
时，我得到的是：
:set请注意:set

为什么color 4用于python文件？我的shiftwidth去了哪里（例如）？
答案 0 :(得分：2)
:verbose set optionname?会告诉您optionname的当前值及其设置位置。
默认的Python设置在：
中定义$VIMRUNTIME/ftplugin/python.vim
请注意，它们遵循Python的“标准”，因此更改任何内容可能会或可能不会导致问题（例如，使用短线）。
要覆盖这些默认设置，请在以下位置创建自己的Python ftplugin：
~/.vim/after/ftplugin/python.vim
并添加所需的选项：
setlocal shiftwidth=2
setlocal tabstop=2
顾名思义，该脚本来自内置之后的，这使其成为覆盖内置文件类型特定设置并添加自己的设置的正确位置。

Vim附带了几个文件类型的插件。我认为引起您问题的是：https://github.com/vim/vim/blob/master/runtime/ftplugin/python.vim
您可以尝试删除该文件。或者只找到您不喜欢的选项，:let g:OPTION_NAME = 0。这里还有一些关于覆盖ftplugins的讨论：https://vi.stackexchange.com/questions/6658/how-to-override-a-ftplugin#6659。
