Just for fun: Get your daily Dilbert comic and display it. If you provide a directory name as argument, it'll be saved to dirname/dilbertyyyymmdd.gif where yyyymmdd is todays date.

pack .lMichael Jacobson: Also see Comic Server for some code to get a bunch of comic strips from uComics. Or you can check out (on windows only ~ sorry) in a TclKit application that servers the comics and display them in a embededd MSIE frame using optcl. Get the application here ... http://mywebpages.comcast.net/jakeforce/COMon!ics.kit (96kb). (I use this code in NewzPoint)
02. Aug. 2005: The Text for the Daily Dilbert comic changed. Replace the lsearch line with the following (This has already been done; the if 0 { wrapper was added to make the version grabbed by wish-reaper operate correctly):
if 0 {
set ln [lsearch -inline -glob $b "*ALT=?Today's Comic*"]
}RLH 20050802: I get the error:
if 0 {
"Can't read "picurl": no such variable while executing "http::geturl http://www.unitedmedia.com$picurl"
}RS Have you applied the fix above? It worked for me after I did it.
RLH I had read the post wrong and thought it was fixed above. Works now and I have commented out the old line above and added the one that works.
escargo 3 Aug 2005 - Touched up the previous included text to make compatible with wish-reaper.
RLH Why would you put "if 0" around the error message I was getting?
escargo 3 Aug 2005 - The reaping tools (wiki-reaper, wish-reaper, and XotclIDE) can extract what they think is code from the wiki pages. The definition of code is simple; too simple in several cases. One such case is the error message you copied into the page. When reaped, that error message becomes a line of code, the last one in the file. When wish tries to run the code, the error message causes wish to throw an error. By using the if 0 { wrapper, wish will ignore it. The text can stay on the page, somewhat distorted, but still there; the reaped page will still execute, though it has some dead code. It's a compromise.
RLH Cool. I wasn't complaining just wondering and now the cat is satisfied. :)
