Swappy

Swappy lets you easily swap between config file sets.

• You have, for instance, 2 different .vimrc files that you switch back and forth between depending on the circumstances. It doesn't have to be .vimrc files; it can be any config file. In fact, it doesn't even have to be a config file, it can be any file—even multiple files!
• You want to take someone's dotfiles out for a spin, and easily switch back to yours.

gem install swappy

Run swappy --help as a sanity check.

First, you put a .swappy.json config file in your ~. Here's an example:

{
  "config_sets": {
    "vim_heavy": {
      "link_root": "~",
      "source_root": "~/.config_sets/vim_heavy",
      "configs": {
        ".vimrc": "vimrc"
      }
    },
    "vim_minimalist": {
      "link_root": "~",
      "source_root": "~/.config_sets/vim_minimalist",
      "configs": {
        ".vimrc": "vimrc"
      }
    }
  }
}

This file has two config sets:

• vim_heavy (files live in ~/.config_sets/vim_heavy)
• vim_minimalist (files live in ~/.config_sets/vim_minimalist)

You can verify these are configured correctly by running swappy list. You should see:

vim_heavy
vim_minimalist

When you issue the command swappy swap vim_heavy, ~/.vimrc will now be a symbolic link to ~/.config_sets/vim_heavy/vimrc.

"BUT WAIT!", you say, "What happens if I already have a .vimrc in my ~?" I'm glad you asked. Swappy will back it up within the same directory. The backup file will be named with a timestamp, like this:

.vimrc.backup.1399229001

Even your symlinks will be backed up!

This effectively means that a history of your swaps will be stored within the same directory.
