By default, you get a single bar at the bottom of all your screens. To change that, you'll unsurprisingly need a config file. This page details putting together the skeleton for your config to get you to a stage where you can start configuring modules. It may look long and overwhelming, but that is just because the bar supports a lot of scenarios! If you want to see some ready-to-go config files check the [examples folder](https://github.com/JakeStanger/ironbar/tree/master/examples) and the example pages in the sidebar. ## 1. Create config file The config file lives inside the `ironbar` directory in your XDG_CONFIG_DIR, which is usually `~/.config/ironbar`. Ironbar supports a range of configuration formats, so you can pick your favourite: - `config.json` - `config.toml` - `config.yaml` - `config.corn` (Experimental, includes variable support for re-using blocks. See [here](https://github.com/jakestanger/corn) for info) You can also override the default config path using the `IRONBAR_CONFIG` environment variable. ## 2. Pick your use-case Ironbar gives you a few ways to configure the bar to suit your needs. This allows you to keep your config simple and relatively flat if your use-case is simple, and make it more complex if required. ### a) I want the same bar across all monitors Place the bar config inside the top-level object. This is automatically applied to each of your monitors.
JSON ```json { "position": "bottom", "height": 42, "start": [], "center": [], "end": [] } ```
TOML ```toml position = "bottom" height = 42 start = [] center = [] end = [] ```
YAML ```yaml position: "bottom" height: 42 start: [ ] center: [ ] end: [ ] ```
Corn ``` { position = "bottom" height = 42 start = [] center = [] end = [] } ```
### b) I want my config to differ across one or more monitors Create a map/object called `monitors` inside the top-level object. Each of the map's keys should be an output name, and each value should be an object containing the bar config. You can still define a top-level "default" config to use for unspecified monitors. Alternatively, leave the top-level `start`, `center` and `end` keys null to hide bars on unspecified monitors. > [!TIP] > To find your output names, run `wayland-info | grep wl_output -A1`.
JSON ```json { "monitors": { "DP-1": { "start": [] }, "DP-2": { "position": "bottom", "height": 30, "start": [] } } } ```
TOML ```toml [monitors] [monitors.DP-1] start = [] [monitors.DP-2] position = "bottom" height = 30 start = [] ```
YAML ```yaml monitors: DP-1: start: [ ] DP-2: position: "bottom" height: 30 start: [ ] ```
Corn ``` { monitors.DP-1.start = [] monitors.DP-2 = { position = "bottom" height = 30 start = [] } } ```
### c) I want one or more monitors to have multiple bars Create a map/object called `monitors` inside the top-level object. Each of the map's keys should be an output name. If you want the screen to have multiple bars, use an array of bar config objects. If you want the screen to have a single bar, use an object. To find your output names, run `wayland-info | grep wl_output -A1`.
JSON ```json { "monitors": { "DP-1": [ { "start": [] }, { "position": "top", "start": [] } ], "DP-2": { "position": "bottom", "height": 30, "start": [] } } } ```
TOML ```toml [monitors] [[monitors.DP-1]] start = [] [[monitors.DP-2]] position = "top" start = [] [monitors.DP-2] position = "bottom" height = 30 start = [] ```
YAML ```yaml monitors: DP-1: - start: [ ] - position: "top" start: [ ] DP-2: position: "bottom" height: 30 start: [ ] ```
Corn ```corn { monitors.DP-1 = [ { start = [] } { position = "top" start = [] } ] monitors.DP-2 = { position = "bottom" height = 30 start = [] } } ```
## 3. Write your bar config(s) Once you have the basic config structure set up, it's time to actually configure your bar(s). Check [here](config) for an example config file for a fully configured bar in each format. ### 3.1 Top-level options The following table lists each of the top-level bar config options: | Name | Type | Default | Description | |--------------------|----------------------------------------|--------------------------------------|----------------------------------------------------------------------------------------------------------------------------| | `name` | `string` | `bar-` | 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 | | `icon_theme` | `string` | `null` | Name of the GTK icon theme to use. Leave blank to use default. | | `ironvar_defaults` | `Map` | `{}` | Map of [ironvar](ironvars) keys against their default values. | | `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. | | `start` | `Module[]` | `[]` | Array of left or top modules. | | `center` | `Module[]` | `[]` | Array of center modules. | | `end` | `Module[]` | `[]` | Array of right or bottom modules. | ### 3.2 Module-level options The following table lists each of the module-level options that are present on **all** modules. For details on available modules and each of their config options, check the sidebar. For information on the `Script` type, and embedding scripts in strings, see [here](script). #### Events | Name | Type | Default | Description | |-------------------|--------------------|---------|--------------------------------------------------------------------------------------------------------------------| | `on_click_left` | `Script [oneshot]` | `null` | Runs the script when the module is left clicked. | | `on_click_middle` | `Script [oneshot]` | `null` | Runs the script when the module is middle clicked. | | `on_click_right` | `Script [oneshot]` | `null` | Runs the script when the module is right clicked. | | `on_scroll_up` | `Script [oneshot]` | `null` | Runs the script when the module is scroll up on. | | `on_scroll_down` | `Script [oneshot]` | `null` | Runs the script when the module is scrolled down on. | | `on_mouse_enter` | `Script [oneshot]` | `null` | Runs the script when the module is hovered over. | | `on_mouse_exit` | `Script [oneshot]` | `null` | Runs the script when the module is no longer hovered over. | #### Visibility | Name | Type | Default | Description | |-----------------------|-------------------------------------------------------|---------------|--------------------------------------------------------------------------------------------------------------------| | `show_if` | [Dynamic Boolean](dynamic-values#dynamic-boolean) | `null` | Polls the script to check its exit code. If exit code is zero, the module is shown. For other codes, it is hidden. | | `transition_type` | `slide_start` or `slide_end` or `crossfade` or `none` | `slide_start` | The transition animation to use when showing/hiding the widget. | | `transition_duration` | `integer` | `250` | The length of the transition animation to use when showing/hiding the widget. | #### Appearance | Name | Type | Default | Description | |-----------|--------------------|---------|-----------------------------------------------------------------------------------| | `tooltip` | `string` | `null` | Shows this text on hover. Supports embedding scripts between `{{double braces}}`. | | `name` | `string` | `null` | Sets the unique widget name, allowing you to style it using `#name`. | | `class` | `string` | `null` | Sets one or more CSS classes, allowing you to style it using `.class`. | For more information on styling, please see the [styling guide](styling-guide).
