**Many, many thanks to all contributors! As of now, 25 of the modules are from various contributors (!), and only 16 from myself.**

bumblebee-status is a modular, theme-able status line generator for the [i3 window manager](https://i3wm.org/).

Focus is on:
* Ease of use (no configuration files!)
* Theme support
* Extensibility (of course...)

One thing I like in particular: You can use the mouse wheel up/down to switch workspaces forward and back everywhere throughout the bar (unless you have mapped the mouse wheel buttons to another action for a widget, in which case this doesn't work while hovering that particular widget).

I hope you like it and appreciate any kind of feedback: Bug reports, Feature requests, etc. :)

Thanks a lot!

Required i3wm version: 4.12+ (in earlier versions, blocks won't have background colors)

Supported Python versions: 2.7, 3.3, 3.4, 3.5, 3.6

Explicitly unsupported Python versions: 3.2 (missing unicode literals)

# Installation
```
$ git clone git://github.com/tobi-wan-kenobi/bumblebee-status
```

# Usage
## Normal usage
In your i3wm configuration, modify the *status_command* for your i3bar like this:

```
bar {
	status_command = <path to bumblebee-status/bumblebee-status> -m <list of modules> -p <list of module parameters> -t <theme>
}
```

You can retrieve a list of modules and themes by entering:
```
$ cd bumblebee-status
$ ./bumblebee-status -l themes
$ ./bumblebee-status -l modules
```

Any parameter you can specify with `-p <name>=<value>`, you can alternatively specify in `~/.bumblebee-status.conf` or `~/.config/bumblebee-status.conf`. This parameters act as a **fallback**, so values specified with `-p` have priority.

Parameters can also be used to override theme settings, such as:

```
$ ./bumblebee-status -p <module>.theme.<theme field>=<value>
# for example, to get a spacer with a red background:
$ ./bumblebee-status -m spacer -p spacer.theme.bg=#ff0000
```

Configuration files have a format like this:
```
$ cat ~/.bumblebee-status.conf
[module-parameters]
<key> = <value>
```

For example:
```
$ cat ~/.bumblebee-status.conf
[module-parameters]
github.token=abcdefabcdef12345
```

To change the update interval, use:
```
$ ./bumblebee-status -m <list of modules> -p interval=<interval in seconds>
```

As a simple example, this is what my i3 configuration looks like:

```
bar {
	font pango:Inconsolata 10
	position top
	tray_output none
	status_command ~/.i3/bumblebee-status/bumblebee-status -m nic disk:root cpu memory battery date time pasink pasource dnf -p root.path=/ time.format="%H:%M CW %V" date.format="%a, %b %d %Y" -t solarized-powerline
}

```

Restart i3wm and - that's it!

## Events
By default, the following events are handled:

- Mouse-Wheel on any module moves to the next/previous i3 workspace
- Left-click on the "disk" module opens the specified path in nautilus
- Left-click on either "memory" or "cpu" opens gnome-system-monitor
- Left-click on a "pulseaudio" (or pasource/pasink) module toggles the mute state
- Right-click on a "pulseaudio" module opens pavucontrol
- Mouse-Wheel up/down on a "pulseaudio" module raises/lowers the volume

By default, the Mouse-Wheel wraps for the current output. You can disable this behavior by providing the parameter `engine.workspacewrap=false` (starting with version 1.4.5). Also, you can completely disable output switching by using `engine.workspacewheel=false`.

You can provide your own handlers to any module by using the following "special" configuration parameters:

- left-click
- right-click
- middle-click
- wheel-up
- wheel-down
For example, to execute "pavucontrol" whenever you left-click on the nic module, you could write:

`$ bumblebee-status -p nic.left-click="pavucontrol"`

In the string, you can use the following format identifiers:
- name
- instance
- button

For example:

`$ bumblebee-status -p disk.left-click="nautilus {instance}"`

## Errors
If errors occur, you should see them in the i3bar itself. If that does not work, or you need more information for troubleshooting, you can activate a debug log using the `-d` or `--debug` switch:

```
$ ./bumblebee-status -d -m <list of modules>
```

This will create a file called `~/bumblebee-status-debug.log` by default. The file name can be changed by using the `-f` or `--logfile` option.

# Examples
Here are some screenshots for all themes that currently exist:

:exclamation: Some themes (all 'Powerline' themes) require [Font Awesome](http://fontawesome.io/) and a powerline-compatible font ([powerline-fonts](https://github.com/powerline/fonts), for example) to display all icons correctly.
