Webactions in Portable AllegroServe


After reading the webactions documentation and tutorial, I've decided to give 
it a try and since I don't have ACL, I've used PortableAserve on CMUCL and 
SBCL.  I had to tweak portableaserve a little, so that I can compile and run 
webactions and I've included the patch to the latest CVS (as of April 26, 
2004).

I've sent (an older version of) this patch to Rudi Schlatte, but he is 
currently busy with other things and I don't know when it'll be in CVS.  So, 
I've decided to post it here, too.

I hacked a little hotel reservation system (only the search part), but I had 
to implement many things in the CLP part, which probably should belong to the 
framework.  E.g. loop constructs, transfer of data between session, query and 
request, slot access, etc.

So, anybody else tried webactions and want to share their experience?

Thanks for the patch, I'll review it and can apply it to CVS.

I use webactions with Allegro on for the Meme web site:
http://meme.b9.com. It's worked out well for handling logins and
transparently following pages. For example, to search on Meme requires
a user to be logged in. So, my map entry for search is:
  ("search" action-check-login action-search "search.clp")

With that, the user is prompted to logged in if they are not already
logged in and then and the results of any pending searches are
computed, then the result page is displayed. So, the action-check-login
doesn't need to know where to direct after after the login is
performed and the action-search can just assume that a there is valid
user login for extracting the preferences of the user.

Great!  I've mechanically changed most of the occurrences of `excl' to 
`acl-compat.excl' and overdid it.  The attached patch fixes this.

Thanks for the patch, committed.

I use LML2 (which is based on HTMLGEN) for all of my output in
Meme. I find it easier to reuse components, take advantage of macros,
and have a consistent styling using Lisp for HTML generation.

Can you give a small example of how you use it with webactions?
