The following table lists each of the bar-level bar config options:

|-------------------|----------------------------------------|--------------------------------------|----------------------------------------------------------------------------------------------------------------------------|
|-------------------|------------------------------------------------|------------------------------------------|----------------------------------------------------------------------------------------------------------------------------|
| `name` | `string` | `bar-<n>` | A unique identifier for the bar, used for controlling it over IPC. If not set, uses a generated integer suffix. |
| `position` | `top` or `bottom` or `left` or `right` | `bottom` | The bar's position on screen. |
| `anchor_to_edges` | `boolean` | `false` | Whether to anchor the bar to the edges of the screen. Setting to false centres the bar. |
| `height` | `integer` | `42` | The bar's height in pixels. |
| `popup_gap` | `integer` | `5` | The gap between the bar and popup window. |
| `margin.top` | `integer` | `0` | The margin on the top of the bar |
| `margin.bottom` | `integer` | `0` | The margin on the bottom of the bar |
| `margin.left` | `integer` | `0` | The margin on the left of the bar |
| `margin.right` | `integer` | `0` | The margin on the right of the bar |
| `layer` | `background` or `bottom` or `top` or `overlay` | `top` | The layer-shell layer to place the bar on. |
| `exclusive_zone` | `boolean` | `true` unless `start_hidden` is enabled. | Whether the bar should reserve an exclusive zone around it. |
| `popup_gap` | `integer` | `5` | The gap between the bar and popup window. |
| `icon_theme` | `string` | `null` | Name of the GTK icon theme to use. Leave blank to use default. |
| `start_hidden` | `boolean` | `false`, or `true` if `autohide` set | Whether the bar should be hidden when the application starts. Enabled by default when `autohide` is set. |
| `autohide` | `integer` | `null` | The duration in milliseconds before the bar is hidden after the cursor leaves. Leave unset to disable auto-hide behaviour. |
