Recipe 6.12. Customizing Vim

6.12.1 Problem

All this customization is great, but it goes away when you quit. You don't want to re-type all your abbreviations and mappings each time you start. How do you customize your Vim environment, and preserve your abbreviations and custom keymappings?

6.12.2 Solution

Create a ~/.vimrc file with your desired options. You can create one from scratch, or copy and modify the global /etc/vim/vimrc file.

What can you put in your ~/.vimrc? Any Vim option that you want. And what might those options be? You can list all option names by typing:

:set all    aleph=224 noarabic    arabicshape noallowrevins noaltkeymap ...

Then look up what they mean:

:help noaltkeymap

This opens the hyperlinked options help page:

:help options

As you can see, a person could happily spend a lifetime fine-tuning Vim (and, with luck, completely avoid doing any real work).

6.12.3 Discussion

When you read the Vim documentation, it's easy to become overwhelmed by its flexibility, and the sheer number of possible options. Start with the basics, as illustrated here, and don't worry about the super-duper geeky stuff until you're sure you actually need it. There comes a point where plain old typing does the job just fine.

This sample ~/.vimrc demonstrates three fundamental Vim features: customizing startup options, abbreviations, and keymaps. Quotation marks are used to comment out lines.

Any changes made to ~/.vimrc take effect the next time you open Vim.
