Minibuf-X appears in Treesitter buffers

[Icy-Thought]

Something is not working properly within the (centaur-tabs-group-by-projectile-project) defun to such an extent that I am somehow able to see hidden buffers within Centaur-Tabs when inside a buffer that is using tree-sitter.

For testing purposes try the following snippet from my personal config: (relies on elpaca, modify as desired)

Note

If you only remove (centaur-tabs-group-by-projectile-project) from the equation, then the buffers won't appear; as expected.

I'll look into it!

[toyboot4e]

Cause: Mini* is grouped to the current projectile project:

centaur-tabs/centaur-tabs-interactive.el

Line 428 in 38598c2

(list (projectile-project-name)))

Workaround: add the following after line 424:

          ((string-equal " *" (substring (buffer-name) 0 2)) '("group-for-hiding-minibuffers"))

I think the original function centaur-tabs-buffer-groups is not handling the problem properly, either. I'll open another issue for that.

It calls centaur-tabs-get-group-name and *Mini buffer group name result in centaur-tabs-common-group-name, which is "Comman". If you're in a "Common" group buffer, you'll see *Mini buffers in the tab line. I guess *Mini buffers deserve their own group so that they are always hidden.
