Replaces #596. Differences:
- Tests and metavar.
- Uses “jobnum” name in place of “jobs”.
- Does not use subshell for zsh. Also counts jobs correctly in zsh.
- Adds an option to force showing jobnum segment even if there are no jobs.
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.
