80281b01 RS |
648 | |
649 | This construct makes buffer BUFNAME empty before running BODY. | |
650 | It does not make the buffer current for BODY. | |
651 | Instead it binds `standard-output' to that buffer, so that output | |
652 | generated with `prin1' and similar functions in BODY goes into | |
653 | the buffer. | |
654 | ||
655 | At the end of BODY, this marks buffer BUFNAME unmodifed and displays | |
656 | it in a window, but does not select it. The normal way to do this is | |
657 | by calling `display-buffer', then running `temp-buffer-show-hook'. | |
658 | However, if `temp-buffer-show-function' is non-nil, it calls that | |
659 | function instead (and does not run `temp-buffer-show-hook'). The | |
660 | function gets one argument, the buffer to display. | |
661 | ||
662 | The return value of `with-output-to-temp-buffer' is the value of the | |
663 | last form in BODY. If BODY does not finish normally, the buffer | |
664 | BUFNAME is not displayed. | |
665 | ||
666 | This runs the hook `temp-buffer-setup-hook' before BODY, | |
667 | with the buffer BUFNAME temporarily current. It runs the hook | |
668 | `temp-buffer-show-hook' after displaying buffer BUFNAME, with that | |
669 | buffer temporarily current, and the window that was used to display it | |
670 | temporarily selected. But it doesn't run `temp-buffer-show-hook' | |
671 | if it uses `temp-buffer-show-function'. | |
