Question: Two split windows open buffer behavior #142

Closed sebastianpech closed 5 years ago

sebastianpech commented 5 years ago

I haven't found anything concerning the following behavior:

When in window with purpose A, switching buffer to one that also has purpose B, instead of the emacs default behavior the buffer is viewed in the window with purpose B (though not dedicated) instead of in the window that is currently selected.

Is this intended and if yes, is it possible to disable it?

Yes and yes. It is intended and can be changed. Put the following elisp code in your configuration (to run after window-purpose was loaded):

(setcdr (assq 'switch-to-buffer purpose-action-sequences)
        '(purpose-display-maybe-same-window
          purpose-display-reuse-window-buffer
          purpose-display-reuse-window-purpose
          purpose-display-maybe-other-window
          purpose-display-maybe-other-frame
          purpose-display-maybe-pop-up-window
          purpose-display-maybe-pop-up-frame))

The variable purpose-action-sequences controls how Purpose tries to display a buffer in different common scenarios, and in what order. By default, purpose-display-maybe-same-window is lower on the list, but this code puts it higher. Specifically, what you experienced is caused by *-reuse-window-purpose which by default has a higher priority than *-maybe-same-window.

Thanks, that solved it!
