Configuration

aform-rs can be customized via a TOML configuration file. The application looks for configuration in the following locations (in order):

1. ./aform.toml (current directory)
2. ~/.config/aform/aform.toml (XDG config directory)

Color Formats

Colors can be specified in three formats (you can mix them freely):

Format	Example	Description
RGB	"255,128,0"	Comma-separated RGB values
Hex	"#FF8000"	Standard hex color (case-insensitive)
Verbose	{ r = 255, g = 128, b = 0 }	Explicit field notation

Partial Configuration

You only need to specify the settings you want to change. Any omitted settings will use the default values:

[theme.border]
active = "255,165,0"  # Just change the active border to orange
