Though I've run many books through DP's proofing and formatting workflow, I always thought it would be easier and more fun if the computer gave feedback about what it thought of the page as it was being proofed. To test this out, I have written a multi-pane editor that may be useful for etext production. I loaded a book into the demo version of the program at http://etext.ws/ppe.php and I'm interested to know if it works for different users with different browsers. It uses several HTML5 pieces that I think are safe. Open source, MIT license, as is all my software tools for etext production. The left pane is a text edit area for a page. Center pane shows the results of analysis for that page. Top pane is a clickable image of the page. Various status information is lower right. Still to do: spelling check, common scanno flags and many more regex checks. Right now it includes spaced or crunched punctuation, poetry detection, end-of-line hyphens (which may be resolved with the DHYP button) and a few others. I also want to use a magnifier jquery plugin on the image to dynamically enlarge the area under the mouse instead of having to open another window. I will solo post-process a few books using it. If I can make it work well enough, I'll add the page queue code (i.e. "next unproofed page"), instead of how it is now, where you select the page to proof or it gives you a random page. As you proof, the status area displays how many times the page has been proofed, as this is all tracked along with all earlier revisions in the database. There is no login required and I'd appreciate if you would take a look at it. Feedback welcomed to the email shown in the application. I'll summarize (if there is any interest) back to this thread. --Roger
