Option to have per pane borders

[David Marte]

Hi everyone,

12 years using tmux here, first time joining the mailing list.

I’ve put together a patch that adds a per-pane-borders option, which draws a full border around each tiled pane (as opposed to the current shared-border setup), while respecting different border types, border status and pane scrollbars. The idea came when I saw other multiplexers use per window borders and I thought it made a lot of sense. I saw this plugin https://github.com/kishisan/tmux-pane-border that tries to accomplish the same though in a different way as the closest way to make it possible on tmux. Thought perhaps I could try implementing it myself on tmux.

PR with the diff and an asciicast demo Is here: https://github.com/tmux/tmux/pull/5433

Before I put more time into polishing this, I wanted to check:

• Is this something that’d be considered for core, or would it fit better as a new option built on the existing pane-border-style/pane-active-border-style machinery?

• Any concerns about interaction with pane-border-status or existing layout code I should think about?

Happy to rework based on feedback.

Thanks,

David
