#
# Replicate some of Awesome's default layout manipulation configuration for Sway
#
# Differences:
# - Layout switching doesn't use the spacebar (i.e. i3/Sway behavior to switch to/from floating windows)
# and uses the 'A' key instead (as in auto)
# - Resizing windows uses i3/Sway's more versatile Mod4+r
# - no tags
# - no Maximize/Minize, alternatives to Maximize would be to switch to Stacked/Tabbed layouts
# via Mod4+w or Mod4+s.
# - kill focused client is available on Mod4+Shift+q (instead of Mod4+Shift+c, which maps to Sway's
# config reload)
# - probably many more ...
# Awesome-style container traversal using Vim-like binding
set $next j
set $prev k
#
# Moving around:
#
# Move your focus around
bindsym $mod+$next focus next
bindsym $mod+$prev focus prev
# _move_ the focused window with the same, but add Shift
bindsym $mod+Shift+$next move next
bindsym $mod+Shift+$prev move prev
#
# Layout:
#
workspace_layout auto left
# This is usually bound to $mod+space, but this works well in practice by keeping
# all the layout switching keys grouped together.
bindsym $mod+a layout auto next
bindsym $mod+Shift+a layout auto prev
# Promote a child to master position in an auto layout
bindsym $mod+Control+Return move first
# Increase/decrease number of master elements in auto layout
bindsym $mod+Shift+h layout auto master inc 1
bindsym $mod+Shift+l layout auto master inc -1
# Increase/decrease number of slave element groups in auto layout
bindsym $mod+Control+h layout auto ncol inc 1
bindsym $mod+Control+l layout auto ncol inc -1
#
# Resizing containers:
# Again, not really the way Awesome works well, but in spirit with i3/Sway and it works well.
