dwm-status

DWM status service which dynamically updates when needed. Heavily inspired by i3status-rust.

Example status bar:

Requirements

cargo, rustc and lib{dbus,gdk-pixbuf,notify,x11}-dev are required to build the binary.

Build and run

$ # dev mode
$ cargo run -- <config-file>
$ # release mode
$ cargo build --release
$ ./target/release/dwm-status <config-file>

Or install globally to ~/.cargo/bin:

$ cargo install dwm-status

Nix support

Build as flake:

$ nix build

And run:

$ ./result/bin/dwm-status <config-file>

Configuration

The config-file can be a HJSON, JSON, TOML or YAML file. For each possible format a config file filled with the default values can be found in examples/default-settings. The type of file is determined by its suffix.

For an example how to use icons in the status bar see examples/icon-settings/nerd-font.toml. You need to install and specify one of the available nerd fonts in your config.h in dwm to use the icons in the example config, e.g.:

static const char *fonts[] = { "Ubuntu Mono Nerd Font:size=9" };

General options

debug	-	Deprecated, will be removed in 2.0.0. Log level is now INFO by default.
order	[]	List of enabled features in order.

mute	"MUTE"	Text representation if muted.
template	"S {VOL}%"	Text representation if unmuted. ({VOL} gets replaced with the current volume, {ICO} gets replaced with the icon)

Feature: Backlight

Feature: Battery

Note: The upower daemon has to be running for receiving DBus messages.

Watches UPower DBus signals for added or removed batteries and changes of battery states.

If notifier is enabled, currently discharging and the capacity of the fullest battery is under the configured values value, warning notifications with urgency normal or critical (depending on the configured critical value) are sent.

Shows following information per battery:

status	example	notes
charging	▲ 10% (01:23)	In parentheses time to full
discharging	▼ 50% (02:03)	In parentheses time to empty

Shows following information as feature block (ICO gets replaced with an icon if any are defined):

battery count	example	notes
0	NO BATT
1	▼ ICO 50% (02:03)
2	▼ ICO 50% (02:03) · ICO 50%	Batteries ordered alphabetically by name

Configuration options

name	default	description
charging	"▲"	Text representation for status charging.
discharging	"▼"	Text representation for status discharging.
enable_notifier	true	Whether to enable the notifier.
icons	[]	List of icons, which represent different stages relative to the current battery state, e.g. ["LOW", "MIDDLE, "HIGH"].
no_battery	"NO BATT"	Text representation if no battery present.
notifier_critical	10	Maximum battery value to notify via critical notification.
notifier_levels	[2, 5, 10, 15, 20]	Battery values to notify.
separator	" · "	Separator string between mutliple battery infos.

Feature: CPU Load

Shows CPU load taken from /proc/loadavg in configured format and refreshes every n seconds.

Configuration options

name	default	description
template	"{CL1} {CL5} {CL15}"	Text representation. ({CLx} gets replaced with the load of last x minutes for x in {1, 5, 15})
update_interval	20	Update interval in seconds.

Feature: Network

Note: The commands ip, dig and iwgetid need to be in PATH.

Configuration options

name	default	description
format	"%Y-%m-%d %H:%M"	Time format of chrono crate.
update_seconds	false	Whether to update time feature every second or minute, automatically set by parsing format.

Contributing

You need rustup with nightly toolchain, rustfmt, clippy and lib{dbus,gdk-pixbuf,notify,x11}-dev. I recommend the installation of racer.

If your are using nix you can use shell.nix for all dependencies except the rustup toolchain and components:

$ nix-shell
[nix-shell]$ rustup install nightly
[nix-shell]$ rustup default nightly
