Thoughts on XMLishkindasorta things
by Christopher G. Petrilli 31 Jan '99

31 Jan '99

Yes I'm being vague, lest the XMLnazis breat me up again... Anyway, so I've MOSTLY got the 'store' feature working, and here's how I'm trying to do it... * Create new tag 'store', used like this: <?ztml store var foo ?> Actually what comes after the store command isn't that important, it's a neat trick... it creates a tag object as if the user had inserted <?ztml var foo ?> This is stuffed in the render string, but when render time comes, rather than putting out information for the output stream, it shoves the object into the register. * Introduced the concept of a parameter entity into the parser, which has its own table for management, seperate (for future use! :-) For those unfamiliar with XML things, a parameter entity is actually slightly different than a regular entity (character entity)... it's formed thusly: %ztml; Note the use of the '%' character, rather than the '&' character. My reading of the standard says that this is the correct use, not the regular character entity (&ztml; was the proposed one). * Converted the HTML-style parser to re, rather than regex... So here's how the trick works... the 'store' tag inserts the tag object into the register rather than the rendering string. When the parser sees an entity (parameter entity, not character), it looks it up in the table to see if it matches---same way the regular tag lookup works---if it does it inserts that into the output stream... Now the trick is that when the constructor is called on the entity object it doesn't do anything (right now it's just a 'pass')... the neat stuff happens when it's called (__call__) and it executes it's render method. THEN it goes and grabs the current object out of the register and renders it at that point... if it can't find anything, it doesn't do anything. Make sense? Or was I writing code entirely too late after too much wine? :-) BTW, a side effect of this is that I've been documenting the HT_String.py, HT_HTML.py and a few other modules here and there as I figure out how they work :-) Chris -- | Christopher Petrilli | petrilli(a)amber.org

DTML and CSS2: any caveats?
by Stuart Hungerford 31 Jan '99

Hi all, This is assuming I can find a browser that properly handles CSS ;-) If I wanted to use CSS elements in the HTML generated from DTML, are there any caveats/warnings/issues etc I need to know about first?

Using ZTemplates alone on various platforms...
by Stuart Hungerford 30 Jan '99

30 Jan '99

Hi All, I've just started exploring the wonderful world of Zope! I'd like to start using ZTemplates immediately (if my ISP will agree to installing Python). I've downloaded and unpacked the ZTemplates stuff and If I've read the README right, there's a C file that needs to be compiled? The doco. also refers to getting this file in precompiled format from the binary porting kit? All this is no problem in Linux, but are there Win32 versions already precompiled? Stu

Chris wrote: > <?ztml #var arg ?> Ahh, tis nuthin better than seeing a patch accompany a proposal :^) Here's my main beef with this. The ostensible goal of the XML syntax is to make it parse-able by new tools. Unfortunately, a valid use of the current syntax: <font size=""> which is legal, would become: <font size="<?ztml #var arg ?>"> which *not* valid XML...is it? That is, can you have markup inside markup? --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

Problem setting values for Z SQL Method
by Michael Bailey 30 Jan '99

30 Jan '99

Hi all, I'm trying to set a value to be used in a Z SQL method. I added the following lines to a dtml page but the method does not see the values 'artist_id'.        I tried setting 'artist_id' as a folder property but that didn't work either. I am getting artist_id from another SQL method as it is an auto_increment value and I need to use it to add a row to a joining table. thanks, Mike Bailey

Bug in pcgi/parseinfo.c
by Scott Robertson 29 Jan '99

29 Jan '99

pcgi/parseinfo.c had a bug in the pcgiEnviromentToResourceAssignment() function that prevented it from properly reading some enviroment variables. Here's the patch to fix this problem. By the way is there some place we should be uploading patches to other than the list? The contrib area by chance? --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

endian issues
by tyler 29 Jan '99

29 Jan '99

Hi, we're trying to move our Zope object database from a sparc machine to a pentium and we're having endian problems. Should the data file be more platform independent than it's acting, or are we SOL? You might also note that the subject of this mail is plural- does anyone have a definitive answer to the endianess vs. endianity debate that this problem has sparked in our office? That's not really list related, just wondering... Anyway, thanks for any help! tyler

Test message - please ignore
by Ken Manheimer 29 Jan '99

29 Jan '99

Traffic has been sufficiently sparse, and the changes on zope.org (different host, new mailing list manager version, different web interface, etc) are sufficient to warrant one last test before i ignore it for the weekend. Ken klm(a)digicool.com When i die, i hope i go peacefully, in my sleep, like my grandfather, and not screaming in terror, like his passengers. - Steven Wright, Emo Phillips, somebody like that?
