Description: Switch focus in the specified direction, but with the following
difference to the usual ioncore.goto_next function:
* When switching focus down (resp. up) from the bottom (resp. upmost) client,
switch to the next (resp. previous) workspace.
* When switching focus right (resp. left) from the rightmost (resp. leftmost)
client, switch to the next (resp. previous) screen.
Usage: Add bindings for
wrap_wsscr.goto_next(_sub, 'up', {no_ascend=_})
wrap_wsscr.goto_next(_sub, 'down', {no_ascend=_})
wrap_wsscr.goto_next(_sub, 'right')
wrap_wsscr.goto_next(_sub, 'left')
to the "WTiling" section of cfg_tiling.lua.
If you want support for floating workspaces, add bindings for
wrap_wsscr.goto_next(_chld, 'up', {no_ascend=_})
wrap_wsscr.goto_next(_chld, 'down', {no_ascend=_})
wrap_wsscr.goto_next(_chld, 'right')
wrap_wsscr.goto_next(_chld, 'left')
to the "WScreen" section of cfg_notioncore.lua.
