Listing buffers by tab using consult and bufferlo

I've gotten into the habit of using tabs, via tab-bar, to organise my buffers when I have multiple projects open at once. Each project has its own tab. There's nothing fancy here (yet), I simply open a new tab manually before opening a new project.

A while ago I added bufferlo to my config to help with getting consult-buffer to organise buffers (somewhat) by tab. I copied the configuration from the bufferlo README and started using it. It took me a little while to notice that the behaviour wasn't quite what I wanted. It seemed like one buffer "leaked" from another tab.

In the image above all files in ~/.emacs.d should be listed under Other Buffers, but one has been brought over into the tab for the Sider project.

After a bit of experimenting I realised that

1. the buffer that leaks is the one I'm in when creating the new tab, and
2. my function for creating a new tab doesn't work the way I thought.

My function for creating a new tab looked like this

(lambda ()
  (interactive)
  (tab-new)
  (dashboard-open))

and it turns out that tab-new shows the current buffer in the new tab which in turn caused bufferlo to associate it to the wrong tab. From what I can see there's no way to tell tab-new to open a specific buffer in the newly created tab. I tried the following

(lambda ()
  (interactive)
  (with-current-buffer dashboard-buffer-name
    (tab-new)))

hoping that the dashboard would open in the new tab. It didn't, it was still the active buffer that popped up in the new tab.

In the end I resorted to use bufferlo-remove to simply remove the current buffer from the new tab.

(lambda ()
  (interactive)
  (tab-new)
  (bufferlo-remove (current-buffer))
  (dashboard-open))

No more leakage and consult-buffer works like I wanted it to.
