Default colors range from red (full battery) to white (no battery) but can be changed via the
`battery' and `battery_gradient' settings.
Default presentation is a formatted percentage string (with keyword `batt'). The `gamify' setting
changes this to a sequence of video game hearts.
Number of steps from 100% to 0% / number of video game heart icons is controlled by the `steps'
setting (default 5).
- Added segment function to powerline.segments.common.
- Added test to check return values.
- Added default colorschemes for everything but iPython.
Ref #477
cwd segment was not drawing inner separators because of new default for
multisegment functions. use_path_separator was added because current variant
looks bad for my taste.
If weather or system_load segments were moved to the left draw_soft_divider
variant resulted in incorrect renderring. Thus it was replaced by
draw_inner_divider.
Previous variant was bad because
1. draw_divider only applied to soft dividers. Hard dividers were always drawn
2. But there was a hack with width=auto segments: for this segments draw_divider
setting applied always.
Now there are no additional dependencies: draw_*_divider applies no matter what
other properties of the segment are.
Those exceptions are now handled and logged at top level, thus no need to handle
them in segment.
Ref #330, it is now fixed for zsh/zpython
Note: do not use zsh/zpython + python3, it does not work properly, even though
this changeset contains fixes for it as well
Fixes#360
NOTE: Documentation now gets attached to *classes*, not actual segments. Hiding
away classes (by changing their names to start with `_`) and/or doing
self.__doc__ = self.__class__.__doc__
does not work (hiding classes only hides documentation completely). I am
not familiar with sphinx enough to say how this should be fixed.
