This modifies `get_active_binding` to treat bindsym --to-codes separately: per each keysym `i` in `binding->keys`, look through the list of matching keycodes in `binding->translations[i]`. Another solution is to take the cartesian product of all syms and make a binding per each product. This makes retranslation more difficult though because the dups from the old layout have to be cleared out before translating to the new `xkb_layout`. Whether by retaining a parent binding, searching through all bindings for matching `binding->command`, or some other ref count structure, that would introduce more complexity than modifying get_active binding to account for dups. Notice this requires no changes to the existing retranslation logic.

to test: swaymsg 'input * xkb_layout us'
swaymsg 'bindsym --to-code $mod1+a exec notify-send hi'
# test that alt+a sends hi according to a US QWERTY layout
swaymsg 'input * xkb_layout fr'
# Test that alt+q now sends hi, as the French AZERTY layout is the new
# "first configured layout" that `--to-code` should respect
swaymsg 'input * xkb_layout us'
swaymsg 'bindsym --to-code Print+a exec notify-send hi'
# test that Print+a sends hi according to a US QWERTY layout
swaymsg 'input * xkb_layout fr'
# Test that Print+q now sends hi, as the French AZERTY layout is the new
# "first configured layout" that `--to-code` should respect |

@kennylevinsen what do you think of this approach? It's been working without issues for me so far. |
|
@emersion Any concerns with this approach? |

A reasonable rate of poking is if roughly 2 weeks have passed - daily is far too much noise for volunteers who are also busy with their day jobs and other projects. |
