I have a custom Vim configuration that I've been putting together. There's a number of cool plugins and features that aid in PHP development. However, when I open a large file (couple thousand lines) these features make vim crawl.
What I'm currently doing is renaming .vimrc to .vimrc- then relaunching vim when dealing with these large files so I have the default configuration. What I'd like to do is toggle between vimrc's without having to leave vim. Think that's possible? It's sorta like sourcing the .vimrc after changes but I need to source another file to override my default configuration.
