note stefan k Hi,<br> first, as I posted before, although I really appreciate when someone writes code in elisp (even if it were just for the fun in it ;-) I suggest using the function <code>cperl-check-syntax</code> which invokes <code>mode-compile</code> which is quite clever. One gain would be that you can jump to errors found my that process directly. Another gain would be the customizability of <code>mode-compile</code>. There is one variable called <code>mode-compile-other-frame-p</code> which could be used to achieve your first goal in a way: simply let it use a different frame (known as "window" to all other users ;-) and hide that frame somewhere on your desktop where it won't get in your way. <p> Another possibility might be to use one of the hooks run before and after running <code>mode-compile</code> but after looking at the code I can't find an obvious way. <p> As to your second question you're probably interested in using the emacs-feature where you can pass a region or a buffer to a shell command and replace the region/buffer with the result of that command. This can also be used for sorting lines for example. <p> This call would look like this: <code> C-x h C-u M-| perltidy </code> Here <code>C-x h</code> should mark the whole buffer, the prefix argument <code>C-u</code> enables the replacement of the region and finally <code>M-|</code> calls the function <code>shell-command-on-region</code> which asks for the command to use. Unfortunately I don't have perltidy at hand to test it. <p> Putting all this into a single function which can be bound to a key would be like: <code> (defun my-perltidy () "Call perltidy on the current buffer. This replaces the current content of the buffer with the output of the perltidy programm. You must have perltidy installed. See http://perlmonks.org/?node_id=399154 for the start of this." (interactive) (when (yes-or-no-p "Really run perltidy? ") (goto-char (point-min)) (shell-command-on-region (point-min) (point-max) "perltidy" nil t))) </code> And then: <code> (add-hook 'cperl-mode-hook '(lambda () (local-set-key '[(control c) (control t)] 'my-perltidy))) </code> or something like that. <p> Please note, that I use XEmacs, but this code should be usable on both emacsen, I guess <p> <b>Update Thu Oct 14 14:15:41 CEST 2004:</b> Added note on emacs-version <!-- Node text goes above.
