Popwin not working with auctex

[elemakil]

I want the *TeX Help* buffer produced by AUCTeX to be a popup buffer. I have added the following code to my .emacs:

(push '("*TeX Help*" 
                 :width 80
                 :position right
         :noselect t)
  popwin:special-display-config)

However, when calling TeX-next-error the buffer does not show. I suspect that this is due to the fact that TeX-next-error opens the buffer and then switches focus to the original buffer. In order to counteract this I have included the :noselect t option.

Can you help with this?

I see the same behavior with:

(push '("\\*.* output\\*" 
            :regexp t 
            :tail t 
            :noselect t) 
 popwin:special-display-config)

Setting either :noselect or :stick has no apparent effect.

Sorry for the confusion. I mean that the above does show similar behavior (popup opens and closes instantly) when pressing C-c C-l. C-c <backtick> does work with that rule, though.

Maybe AUCTeX doesn't use display-buffer to display the buffer. In this case, popwin can't be used.

[ThibautVerron]

It uses TeX-pop-to-buffer, which is a wrapper around pop-to-buffer. Rewriting this wrapper in terms of its popwin version did result in messy configuration (3 open buffers, two of them showing the initial tex buffer), I didn't have time to investigate more. TeX-recenter-output-buffer makes two calls to TeX-pop-to-buffer, probably only one needs to be changed.

Relevant code: https://github.com/jwiegley/auctex/blob/master/tex-buf.el#L233

How about (popwin:popup-buffer (TeX-active-buffer) :noselect t :tail t) for the contents fo the function?
