DWM status service which dynamically updates when needed.
Heavily inspired by [i3status-rust](https://github.com/greshake/i3status-rust).

Example status bar:
![example-sceenshot](https://raw.githubusercontent.com/Gerschtli/dwm-status/master/examples/images/preview.png)

## Requirements

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

## Build and run

```sh
$ # dev mode
$ cargo run -- <config-file> [--quiet]
$ # release mode
$ cargo build --release
$ ./target/release/dwm-status <config-file> [--quiet]
```
Or install globally to `~/.cargo/bin`:
```sh
$ cargo install dwm-status
```

### [Nix](https://nixos.org/nix/) support

Build as flake:
```sh
$ nix build
```

And run:
```sh
$ ./result/bin/dwm-status <config-file> [--quiet]
```

## 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](https://nerdfonts.com) in your `config.h` in `dwm` to use the icons in the
example config, e.g.:
```c
static const char *fonts[] = { "Ubuntu Mono Nerd Font:size=9" };
```

**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 connected ESSID as well as both public and private IPv4 and IPv6 addresses. Updates get triggered by listening on `ip monitor address link route`.

| `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](https://nixos.org/nix) you can use `shell.nix` for all dependencies except the `rustup`
toolchain and components:

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