A previous commit broke the traffic module by deleting widgets during
each iteration. This is fatal as the widgets contain the traffic
information from the previous iteration, for delta calculation.
Store previous traffic data in the module itself instead.
In order to (hopefully) achieve localization independence, switch from
using pactl for retrieving pulseaudio information to pacmd, which seems
to be unaffected by the LANG environment variable.
fixes#103
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
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
