tab-line group sorting about bufler.el HOT 6 OPEN

There isn't any configuration for that. See

from bufler.el.

If you wanted to implement something like that, you could probably model it on tab-line-tabs-window-buffers.

from bufler.el.

Thanks a lot, I can do the customization with that information.

Please let me know what you come up with, or feel free to submit a PR.

I investigated how tab-line uses tab-line-tabs-buffer-group-sort-function and it turns out that it only uses it inside seq-sort functions as a sort predicate, the name of the variable is misleading, it should be something like tab-line-tabs-buffer-group-sort-predicate-function, but anyway, this makes easy to integrate the same behaviour in bufler's existing code, I just redefined bufler-workspace-buffers as follows:

(cl-defun bufler-workspace-buffers (&optional (frame (selected-frame)))
  "Return list of buffers for FRAME's workspace.
Works as `tab-line-tabs-function'."
  ;; This is specifically for `bufler-workspace-tabs-mode', but it
  ;; needn't be only for that, so it probably belongs here.
  (let (buffers)
    (--tree-map-nodes (bufferp it)
                      (push it buffers)
                      (bufler-buffers :path (frame-parameter frame 'bufler-workspace-path)))
    (if tab-line-tabs-buffer-group-sort-function
	(cl-sort buffers tab-line-tabs-buffer-group-sort-function)
      (cl-sort buffers #'string< :key #'buffer-name))))

In this way the customization is the same as in tab-line and is optional, preserving the original bufler sorting (maybe expected by
other users).

With this I can customize the predicate function to do the sorting as I want.

I also noted a tab-line-tabs-buffer-groups-sort-function (note the additional s in groups) that I think sorts tab-bar elements, but I'm
not sure, and there is no documentation in the code. Maybe a similar customization can be done in that case.

I'll look at this again in the future. It's likely that bufler-workspace-tabs-mode will need to be adjusted or rewritten for changes in Emacs 27/28, and I'll have to do that after testing it for a while.
