Thanks to a tip from Andre I have managed to use runRev in a word press
blog. he says a revlet will also run too...I usually don't contribute
much here because I feel I'm a "baby" compared to all the wizards ...
but perhaps this will be useful to those interested in incorporating
runRev in PHP CMS frameworks. In this case a Word Press mu blog.
http://himalayanacademy.com/blog/taka/2009/11/02/words-to-ponder/
The "chain" of elements in the framework are interesting, as we use
-- an iFrame
-- Calls a .irev page
-- .irev page calls a rev-cgi
-- rev-cgi "starts using" a stack
-- stack function digs for and returns the content
-- results are posted back to word press.
The thing of it is... it's so easy! and so fast... Total lines of code?
22? (spread over three different files and don't forget a 7MB stack is
loaded on every instance...but there is no lag time)
with one or two caveats.
In case any one is interested here is the code:
Word Press Post
(# space and breaks at the beginning to give a little breathing room
above the iFrame below the post title)
<br /><br /><iframe name="get-word" style="border: 0px solid
#ffffff;width:600px;height:400;" src="/resources/lexicon/RandomWord.irev" >
</iframe>
## the css is needed to eliminate the border. iFrames will always
"borderize" so just set the color of the border to the color of your
background and it effectively disappears.
# Assumes you have the wp plug in that allows for pasting html into the
blog and this is set to "allow"
RandomWord.irev # will be displayed into your iFrame, I suspect this
could be a page that contains a revlet...

getRandomLexiconWord.cgi
# it would be nice to be able to call stacks directly with the iRev
engine and
# I think that is on the roster of future for features but for now you
need to
# do a GET of a a rev-cgi that Starts Using a stack
#!/opt/web/bin/revolution -ui
on startup
start using stack "../public_html/resources/lexicon/lexicon.rev"
put getRandomWord() into buffer
put "Content-Type: text/plain" & cr
put "Content-Length:" && the length of buffer & cr & cr
put buffer
end startup
in the stack "lexicon.rev" (a 7 MB stack with about 3500 cards)
I have this function in the stack itself.
function getRandomWord
put (the number of cards of stack "Lexicon") into tCards
put random(tCards) into tWord
put (fld "word" of card tWord of stack "Lexicon") & "|"& \
(fld "definition" of card tWord of stack "Lexicon") into tOutput
return tOutput
end getRandomWord
# Caveat on calling functions in stacks using rev-cgi: a rev.cgi has no
stack context. There fore you need to declare explicitely the stack
reference to any objects in your stack. If you are working on the
desktop in the IDE of course you don't need this and then when you post
the thing to the web it doesn['t work.. .I had gone thru this a few
years back but for got about it and it was until I reviewed some old
function in other web stack that I realize again that you must do this:
put (the number of cards) into tCards
# works in the desktop in an IDE or standalone; fails when invoked by cgi
# this is required, for it to work when call by a CGI even though the
function is in the stack "Lexicon":
put (the number of cards of stack "Lexicon") into tCards
Again: total lines of runRev code (not including html)
