Specifically:
- Do not log exceptions to the same location data is output.
- Fix format, i3bar is no longer using “pseudo-JSON”, also not sure whether it
ever used format `[[right list], [left list]]`, but it definitely does not
now.
- i3bgbar branch is no longer available.
- Yet i3wm supports background color, just with the different key (`background`
vs `background_color`).
Changes:
- Usage determination transferred back to argparse (it wraps).
- Added complete description of lemonbar script to wm-widgets.rst.
- --interval and --height got their arguments clarified by metavar: it was not
clear what units they use.
- --bar-command got its metavar because it is better then default BAR_COMMAND.
- --bar-command short variant is now -C.
Most of the files are empty and need to be copied or rewritten from the
old docs. Font patching docs have been removed entirely and will be
moved to the powerline-fontpatcher repo.
