# apply-user-defaults

`apply-user-defaults` is a small utility to set macOS user defaults
declaratively from a YAML file.

## Usage

To use, simply structure a YAML file like the following:

```yaml
com.apple.dock:
# System Preferences > Dock > Automatically hide and show the Dock.
autohide: true

# System Preferences > Dock > Minimize windows using: Scale effect.
mineffect: "scale"

# System Preferences > Dock > Show indicators for open applications.
show-process-indicators: false

# System Preferences > Dock > Size.
tilesize: 72
```

Then apply it using:

```sh
$ apply-user-defaults path-to-file.yaml
```

You can also see what commands are being run by enabling verbose output:

```sh
$ apply-user-defaults path-to-file.yaml --verbose
==> defaults write com.apple.dock autohide -bool true
==> defaults write com.apple.dock mineffect -string scale
==> defaults write com.apple.dock show-process-indicators -bool false
==> defaults write com.apple.dock tilesize -int 72
Success! Applied defaults.
```

## Template Expansion

Environment variables can also be included using shell parameter expansion
syntax. For example:

```yaml
com.apple.finder:
# Finder > Preferences > New Finder windows show > Home directory.
NewWindowTargetPath: "file://${HOME}"
```

will evaluate to:

```sh
defaults write com.apple.finder NewWindowTargetPath -string "file://$HOME"
```

where `$HOME` is the value contained in the `HOME` environment variable.

This only applies when the string in the YAML file begins with a dollar sign and
is wrapped in braces (just using `$HOME` won't work).

To disable, you may pass the flag `--no-env` or escape the dollar sign, e.g.
`'\\${VALUE}'`.
