To avoid "stray" devices being kept in the list, empty the widgets list
during each iteration and re-populate it from the list of available
interfaces.
fixes#101
The optional parameter "states" can now be used to filter which
interfaces to display. "^" can be used for negation.
For example, to only show "up" interfaces:
-p traffic.states=up
To show all interfaces not in "down" state:
-p traffic.states=^down
fixes#98
psutil.cpu_percent() only outputs to one decimal place anyway, so the trailing 0 is useless.
The prepended 0 is also not important, will only be not 0 at 100% utilization, so why not let it be 100% then and take up one less column otherwise?
No change to default behaviour, but adds boolean to only display used rather than used, total and percentage.
To only show used memory:
-p memory.usedonly=1
OK - I admit it: Mostly for the benefit of Travis and automated testing,
which complains about the DBusException, move to a more generic
exception.
However, this is probably a good idea anyhow, because independently of
the error, setting the song to an empty string is probably the best bet.
Allow the user to filter the state of devices that should be displayed.
It's possible to use both white- and blacklists (and combinations).
For example, to only show devices in state "up":
-p nic.states=up
To only show devices that are not down:
-p nic.states=^down
fixes#84
For modules that use aliases, until now, *only* the alias theme was
considered. This is typically a bad idea (tm), as the "generic" case is
that of a module theme (e.g. "disk", not that of a theme per instance of
the module (i.e. "home", "root", etc.)).
Therefore, introduce the concept of a "class" theme that can be
optionall overridden by a specific module theme.
As a pleasant side-effect, this should bring back the disk icons for all
instances of the disk module :)
fixes#79
If a module defines a callback for a widget's text, an optional
decorator "@bumblebee.output.scrollable" can be used to make the text
scrollable.
In those cases, the desired width is set to (in decreasing order of
priority):
1. whatever the widget defines as "theme.width"
2. whatever the theme defines as "width" for the module
3. whatever the commandline parameter "width" for the module is set to
4. 30 (determined by unfair dice roll)
see #27
Added theme-options ("minwidth" and "align") for setting the minimum
width and the alignment of a widget.
Also, allow widget to provide defaults for the theme options by setting
an attribute in their store called "theme-<name of the theme option>".
For example, a widget can now define a default alignment by using:
widget.set("theme-align", "default-value").
Set the minimum width for uplink and downlink widgets to "down 1000MB",
which should be plenty, and change alignment to right (personally, I
find this looks nicer).
To not have the icons on the left side "jump around" depending on the
value, make them suffixes.
If this solution is not sufficient, alternatively, the widget itself
could perform value padding. In that case, the whole alignment and
min-width settings would be obsolete and the icons could remain on the
left side.

* use psutil instead of "ifconfig" in order to avoid external command
calls
* fix a small bug in the ascii theme (missing colon)
* show statistics per-nic
