i3status-rust

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 the i3 bar. It is also compatible with sway.

For a list of available blocks, see the block documentation. Further information can be found on the Wiki.

Requirements

Most blocks assume you are running Linux, and some have their own system requirements; refer to the block documentation.

Optional:

Font Awesome 4.x is required when using the icons config name = "awesome". For version 5, use name = "awesome5". On Arch Linux version 4 is available in the AUR, and version 5 is available here.
For icons config name = material, a patched version of Google's MaterialIcons-Regular.ttf is required which includes \u{0020} (space), sets a descent ands lower all glyphs to properly align. It can be found here.
Powerline Fonts are required for all themes using the powerline arrow char.

Getting Started

Stable releases are packaged on some distributions:

On Arch Linux: sudo pacman -Syu i3status-rust. The latest development version can be installed from the AUR.
On Fedora 31+: sudo dnf install i3status-rs. For older releases and CentOS, you can install from the COPR.
On Void Linux: xbps-install -S i3status-rust
On NixOS: nix-env -iA nixos.i3status-rust
With Home Manager: programs.i3status-rust.enable = true see available options

Otherwise refer to manual install docs

Configuration

After installing i3status-rust, you need to create a configuration file. Edit the example configuration to your liking. The default location is $XDG_CONFIG_HOME/i3status-rust/config.toml.

There are some top-level configuration variables:

Key	Description	Required	Default
`icons`	The icon set that should be used. Possible values are `none`, `awesome`, `awesome5`, `material` and `material-nf`. Check themes.md for more information	No	`none`
`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, set it to `" <span font_family='NotoSans Nerd Font'>{icon}</span> "` to set font of the icons to be 'NotoSans Nerd Font'	No	`" {icon} "`
`theme`	The predefined theme that should be used. You can also add your own overrides. Check themes.md for all available themes.	No	`plain`
`scrolling`	The direction of scrolling, either `natural` or `reverse`	No	`reverse`
`block`	All blocks that will exist in your i3bar. Check blocks.md for all blocks and their parameters.	No	none

Refer to formatting documentation to customize formatting strings' placeholders.

Integrate it into i3

Next, edit your i3 bar configuration to use i3status-rust. For example:

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.

$ fc-match FontAwesome
fontawesome-webfont.ttf: "FontAwesome" "Regular"

Note that the name of the Font Awesome font may have changed in version 5.
You can use fc-list to see the names of your available Awesome Fonts.

$ 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.

Signalling

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.

i3status-rs can be signalled to force an update of all blocks by sending it the SIGUSR1 signal.

i3status-rs can also be restarted in place (useful for testing changes to the config file) by sending it the SIGUSR2 signal.
