i3status-rs is a feature-rich and resource-friendly replacement for i3status, written in pure Rust. It provides a way to display "blocks" of system information (time, battery status, volume, etc) on bars that support the i3bar protocol.
Install from one of the packages below:
For Fedora/CentOS, you can install from the COPR.
For NixOS, you can also use Home Manager: programs.i3status-rust.enable = true see available options
Otherwise refer to manual install docs
After installing i3status-rust, edit the example configuration to your liking.
The default location is $XDG_CONFIG_HOME/i3status-rust/config.toml.
There are some optional global configuration variables, defined either at the top-level or in a TOML table.
[icons] table:
Key | Description | Default
----|-------------|----------
icons | The icon set that should be used. | "none"
[icons.icons_overrides] | Refer to Themes and Icons below. | None
[theme] table:
Key | Description | Default
----|-------------|----------
theme | The theme that should be used. | "plain"
[theme.theme_overrides] | Refer to Themes and Icons below. | None
Global variables:
Key | Description | Default
----|-------------|----------
icons_format | A string to customise the appearance of each icon. Can be used to edit icons' spacing or specify a font that will be applied only to icons via pango markup. For example, " <span font_family='NotoSans Nerd Font'>{icon}</span> ". | " {icon} "
invert_scrolling | Whether to invert the direction of scrolling, useful for touchpad users. | false
error_format | A string to customise how block errors are displayed. See below for available placeholders. | "$short_error_message\|X"
error_fullscreen_format | A string to customise how block errors are displayed when clicked. See below for available placeholders. | "$full_error_message"
Available error_format and error_fullscreen_format placeholders:
Placeholder | Value --------------------|------ fullerrormessage | The full error message shorterrormessage | The short error message, if available
Blocks are defined as a TOML array of tables: [[block]]
Key | Description | Default
----|-------------|----------
block | Name of the i3status-rs block you want to use. See Blocks below for valid block names. | -
signal | Signal value that causes an update for this block with 0 corresponding to -SIGRTMIN+0 and the largest value being -SIGRTMAX | None
if_command | Only display the block if the supplied command returns 0 on startup. | None
merge_with_next | If true this will group the block with the next one, so rendering such as alternating_tint will apply to the whole group | false
icons_format | Overrides global icons_format | None
error_format | Overrides global error_format | None
error_fullscreen_format | Overrides global error_fullscreen_format | None
error_interval | How long to wait until restarting the block after an error occurred. | 5
[block.theme_overrides] | Same as the top-level config option, but for this block only. Refer to Themes and Icons below. | None
[block.icons_overrides] | Same as the top-level config option, but for this block only. Refer to Themes and Icons below. | None
[[block.click]] | Set or override click action for the block. See below for details. | Block default / None
Per block click configuration [[block.click]]:
Key | Description | Default
----|-------------|----------
button | left, middle, right, up, down, forward, back or double_left. | -
widget | To which part of the block this entry applies | None
cmd | Command to run when the mouse button event is detected. | None
action | Which block action to trigger | None
sync | Whether to wait for command to exit or not. | false
update | Whether to update the block on click. | false
Next, edit your bar configuration to use i3status-rust. For example:
text
bar {
font pango:DejaVu Sans Mono, FontAwesome 12
position top
status_command path/to/i3status-rs path/to/your/config.toml
colors {
separator #666666
background #222222
statusline #dddddd
focused_workspace #0088CC #0088CC #ffffff
active_workspace #333333 #333333 #ffffff
inactive_workspace #333333 #333333 #888888
urgent_workspace #2f343a #900000 #ffffff
}
}
In order to use the built-in support for the Font Awesome icon set, you will need to include it in the font parameter, as above. Check to make sure that "FontAwesome" will correctly identify the font by using fc-match, e.g.
shell
$ fc-match FontAwesome
fontawesome-webfont.ttf: "FontAwesome" "Regular"
Note that the name of the Font Awesome font may have changed in version 5 or above.
You can use fc-list to see the names of your available Awesome Fonts.
shell
$ fc-list | grep -i awesome
/usr/share/fonts/TTF/fa-solid-900.ttf: Font Awesome 5 Free,Font Awesome 5 Free Solid:style=Solid
/usr/share/fonts/TTF/fa-regular-400.ttf: Font Awesome 5 Free,Font Awesome 5 Free Regular:style=Regular
In this example, you have to use Font Awesome 5 Free instead of the FontAwesome 12 in the example configuration above.
You can verify the name again using fc-match
See #130 for further discussion.
Finally, reload i3: i3 reload.
Each block has a State that defines its colors: one of "Idle", "Info", "Good", "Warning", "Critical" or "Error". The state is determined by the logic in each block, for example, the Music block state is "Info" when there is an active player.
When the state is "Error", a short error will be displayed in the block. The full message can be toggled by clicking on the block (overrides any click actions defined in the config). The block will be restarted after error_interval has elapsed.
i3bar has a "power savings" feature that pauses the bar via SIGSTOP when it is hidden or obscured by a fullscreen container. If this causes issues with your bar, try running i3status-rs with the --never-stop argument, which changes the signal sent by i3 from SIGSTOP to SIGCONT.
In addition to the per-block signal config option, i3status-rs can be signalled to force an update of all blocks by sending it the SIGUSR1 signal. It can also be restarted in place (useful for testing changes to the config file) by sending it the SIGUSR2 signal.
Run i3status-rust in a terminal to check the JSON it is outputting.
In addition, some blocks have debug logs that can be enabled like so: RUST_LOG=block=debug i3status-rs where "block" is the block name.
