( #3333=superdoc: print w/replies, xml ) Need Help??

The following snippet steals the regular C-x C-s to automatically perltidy as well. I added a different definition for perltidy-whole-buffer so that the input point is restored to be somewhere near where it was originally. I also added a check to see if the buffer has been modifed before calling out to perltidy.

(add-to-list 'cperl-mode-hook (lambda () (substitute-key-definition 's +ave-buffer 'cperl-save-buffer cperl-mode-map global-map))) (defun cperl-save-buffer (&optional args) (interactive "p") (if (buffer-modified-p) (perltidy-buffer)) (save-buffer t)) (defun perltidy-buffer () (interactive) (let ((orig-point (point))) (shell-command-on-region (point-min) (point-max) "perltidy -st" nil t shell-command-default-error-buffer) (goto-char (if (<= orig-point (point-max)) orig-point (point-max)))))

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
