Hi Todd, This is not really what you're looking for, but just in case it can help: Maybe you can use both readers and make two passes on the file? You'd need to reassemble things afterwards though. IIRC, in the docs about documenting packages with scribble, a special reader is used to format code with comments. Maybe this can help too. Also, just in case, the Lazy-doc package might be of interest for parsing files: <a href="http://planet.plt-scheme.org/display.ss?package=lazy-doc.plt&owner=orseau">http://planet.plt-scheme.org/display.ss?package=lazy-doc.plt&owner=orseau</a> It makes it easy to define moderately complex parsers (not necessarily for scribble). Hope this helps, Laurent P.S. : I know Lazy-doc is probably not really suited to document packages, especially for a Scheme community, but I was young... ;) <div class="gmail_quote">On Sat, Jan 8, 2011 at 16:36, Todd O'Bryan <<a href="mailto:toddobryan@gmail.com">toddobryan@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I'm trying to do some analysis of my student's source files. Trying to grade 90 assignments per week by brute force with no TAs just doesn't work. I want to pull out things like data definitions, contracts, templates, etc., so I can auto-grade the ones that are what I expect them to be, and quickly look at ones that aren't as expected to figure out how many points they should get. Unfortunately, I can't figure out how to get everything that I want. If I use wxme-read, all the comments and comment boxes are just gone, but I still have images and other stuff. If I use wxme-port->text-port, I can use port->string to get all the comments and the original code, but comment boxes get changed to have a single semi-colon in front of each line and things like images get converted to either a dot (for old-style images) or nothing (for 2htdp/image, although I think Robby has updated this to produce dots). I'm sure that I need to either modify wxme-read to convert comments to something that won't disappear or add something to wxme-port->port--probably through register-lib-mapping!--so that when the reader comes upon comment boxes or images it outputs something I can use. Can someone give me some direction? Thanks!
