There's no indication that the tree command is required. When it's unavailable, this sidebar is simply empty. There should be some notification of such instead.

Well, tree is not a hard requirement.. if tree command is not installed on the system, then a custom tree script is used.

However, I managed to reproduce this issue in the following way:

  • tree installed on the system
  • run tmux sidebar, sidebar ok
  • uninstall tree
  • run tmux sidebar again, sidebar in this case empty

The solution was to reload tmux plugins by reloading tmux.conf. When this is done, tmux-sidebar reloads and detects tree is not installed on the system anymore and uses custom tree script.
After the reloading, the sidebar was running ok with a custom script.

The core issue above is that tree command detection is done just on plugin startup. The benefit is speed: command detection is done only once.

Was this the issue you had, or was it some other scenario?

After some further looking up, it seems that I added the -C parameter for color without trying it first without. Given this, it seems obvious now that the tree command would be required, so I'm not sure how I missed that.
