4.3.5 Page ready

The hook ‘wwe-page-ready-functions’ is run when a page is ready to be displayed. The function ‘wwe-show-page-ready’ is set to the hook by default.

Some examples of what to run on ‘wwe-page-ready-functions’:

• Set a default directory
• Go to a specific section
• Switch to buffer automatically regardless of ‘wwe-page-ready-action’ setting
• Enable a help mode like Eldoc mode for EmacsWiki pages
• Display the main image of a page automatically
• Display all images of a page at once

The functions should take the following two arguments:

• BUFFER - The buffer.
• ERROR-MESSAGE - If non-nil an error that occurred during retrieval.

Make sure to use ‘with-current-buffer’ if you need things done to or based on the page buffer.

Note that the point might not be at the beginning of the buffer, for example when there’s a #target (section) in the URL, so if you’re searching for something in the buffer you’ll want to use:

(save-excursion
  (with-current-buffer buffer
    (goto-char (point-min))
