[Copilot]

Pull request overview

Adds a Snacks.nvim-specific wrapper to improve tmux.nvim navigation behavior when Snacks’ custom window engine is in use (notably for snacks_explorer), aligning border/float detection with Snacks’ internal layout state.

Changes:

• Introduce tmux.wrapper.snacks to query focused Snacks picker, infer float vs tiled, and map picker position to Neovim directions.
• Update tmux.wrapper.nvim border and float detection to defer to the focused Snacks picker when present.

Heho,

it would be awesome if you could add tests for snacks behavior as well. Besides tests, pr looks good.

Just out of interest: did you tested it with and without snacks?

kind regards
Alexander

Hi, thanks

Added tests (not without LLM help). snacks are emulated as a mock.

Also tested manually. With snacks everything works as expected (snacks pickers correctly recognized as floating or tiled windows and navigation and resize work correctly).
Without snacks (I just replaced Snacks with nonexistent SnacksAAAA in the plugin) everything works normal without crashing as of before the fix.

heho,

nice. llm produced code (if not sloppy) if completly ok. One picky thing though. remove all comments inside tests, because they are redundant. -- abc above describe("abc..") will age badly.

and please commit normally. thus, i can check what changed only and do not have to review everything again, and again, and :D

kind regards and thx for your help

Thanks, removed redundant comments. I kept only those which actually explain code.

I am not sure what do you mean by "committing normally", probably by committing only diff?
Either way, I have committed changes as a separate commit -- do not forget to squash & edit commit message to keep history clean. :)

Also, github has a nice feature, which allows to see diff even if PR was force-pushed -- just on the right of the push event there is a Compare button :)
