如何防止我的 vim 插件被旧插件覆盖？

Question

我已经通过自制软件安装了 MacVim，并通过将 Pathogen.vim 文件下载到我的 ~/.vim/autoload 目录来安装病原体。我已将 vim-perl 插件克隆到 ~/.vim/bundle 目录中。

但是，当我打开一个 perl 文件时，它使用 MacVimand 中包含的perl.vim 文件中的语法突出显示不是我下载的插件。这是:scriptnames 的输出。请注意所有 MacVim 提供的插件都在那里，我认为最后列出的 perl 会覆盖我下载的插件：

1: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/vimrc
2: ~/.vimrc
3: ~/.vim/autoload/pathogen.vim
4: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/ftoff.vim
5: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/syntax/syntax.vim
6: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/syntax/synload.vim
7: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/syntax/syncolor.vim
8: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/filetype.vim

13: ~/.vim/bundle/vim-scala/ftdetect/scala.vim
14: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/menu.vim
15: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/autoload/paste.vim

27: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/plugin/tohtml.vim
28: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/plugin/vimballPlugin.vim
29: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/plugin/zipPlugin.vim
30: ~/.vim/bundle/vim-scala/after/plugin/help.vim
31: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/gvimrc
32: ~/.vim/bundle/vim-perl/syntax/perl.vim
33: ~/.vim/bundle/vim-perl/syntax/pod.vim
34: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/syntax/pod.vim
35: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/syntax/perl.vim
36: ~/.vim/bundle/vim-perl/ftplugin/perl.vim
37: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/ftplugin/perl.vim
38: ~/.vim/bundle/vim-perl/indent/perl.vim
39: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/indent/perl.vim

这是我的~/.vimrc 文件

set shell=/bin/sh

call pathogen#infect()

filetype off
syntax on
filetype plugin indent on

如果我 :so ~/.vim/bundle/vim-perl/syntax/perl.vim 则文件语法正确突出显示。

如何防止 MacVim 捆绑的覆盖？

Answer 1

包含保护 (if exists("b:current_syntax")) 应该防止默认的 Perl 语法脚本产生任何影响（在您的自定义脚本被获取之后）。

作为一种解决方法，您可以将自己的脚本从 ~/.vim/bundle/vim-perl/syntax/perl.vim 移动到 ~/.vim/bundle/vim-perl/after/syntax/perl.vim，或者创建一个 ~/.vim/after/syntax/perl.vim 脚本

so ~/.vim/bundle/vim-perl/syntax/perl.vim

在里面。
