[!Cheyenne] Discussions about the Cheyenne Web Server

I pretty much gave up on using the app-init.r file ... it is supposed 
to be local to the app, but I found variables spilling to other apps

The question is the remark you make to Terry: I'm trying to get away 
from mixing html and rebol inside the view part of the page ...  
this type of stuff   Hello <%= select session/content 'username %> 
... looks hard to maintain.
Graham

That's my remark ... what's your question?  :)

What need for clean templeting is access to the html source file. 
I'd use the element ID to match with a backing .r file variable / 
component model. No scripting, no tags in the html file. So the question 
is, how can cheyenne let me map these two files?
/path-to-file/page.html mapping to /same-path/page.r. From here, 
page.r works on the response/buffer.

So chyenne loads page.html and does what?
You want cheyenne to load page.r instead?
florin

allows a mapped file to access the response/buffer before it returns 
it.
Yes, where page.r manipulates page.thml

maybe you need this http://cheyenne-server.org/docs/rsp-api.html#def-56

exactly. I tried that tonight as I look at cheyenne for the first 
time. However, the on-page-start/end do not seem to work (in debug 
mode). The instructions are so simple I wonder why it would not work 
though.

are you using rsp pages?
And is it inside a webapp?
florin
24-Aug-2010
[8809x2]
Aha. No. I guess that's where it is. I used .htm. Yet I found that 
the script in the .htm file also is processed. So there is a difference.
Yes, inside a webapp.

It sounds like you want to do what I'm doing here http://rebol.wik.is/Cheyenne/Page_Title/HTML_dialect_demo
 

but have the html page act as the template
whereas i put both together
the element id or divs are used to control the layout of the template
florin

[8814x2]
Yep. Yet, to my mind, it does not achieve my objective.
There is no way a page designer would get into this mess. Appealing 
though.
Graham

[8816]
in that case .. the rsp page would just load the html ... no real 
difference
florin

[8817]
What I need, is a clean html page that my code would not touch directly.
Graham
25-Aug-2010
[8818x2]
well, this has limitations.. what say you want to update all the 
javascript ??
and most html is dynamically generated for me ...
florin
25-Aug-2010
[8820]
From the html page? The javascript would only execute after the response 
buffer is closed.
Graham
25-Aug-2010
[8821x2]
I'm assuming that the JS and HTML are part of your template
so say your library updates . .you have to update all the pages that 
use the js libraries
florin
25-Aug-2010
[8823x3]
The JS is executed by the browser once the buffer is returned to 
the browser. What I want is a mapped .r file to process the DOM source 
on the server side. I don't see where the JS concern.
Graham: so say your library updates . .you have to update all the 
pages that use the js libraries" . The answer is yes. The html file 
would generally behave as any other html file that is not backed 
up by any server side.
There could be a application.r file that allows for global / conditional 
page includes. What I care most is that the html file remains as 
a designer wants it - no scripting.
Graham
25-Aug-2010
[8826]
well, the current rsp script name may be accessible ..and if so, 
you can just load in the html page
florin
25-Aug-2010
[8827x2]
Good. What route do I go to show the .html extension in the browser 
though?
bind-extern RSP to [.htm .j .rsp] ?
Graham
25-Aug-2010
[8829x2]
sounds like it
so your "rsp" page could be .html and the template .htm
florin

And so I did. Then I used the app-init.r to test the results, and 
the before and after page intercept did not work.
Graham
25-Aug-2010
[8832]
and does rsp execute at all?
florin
25-Aug-2010
[8833x3]
Let me check. It shou.d
It does work. Yet the example code does not inject the text before 
the </body> tag.
I mean this example code in the app-init.r: 

 on-page-start: does [
        set 'start-time now/time/precise
    ]

    on-page-end: has [pos elapsed][
        if pos: find response/buffer "</body>" [
            elapsed: now/time/precise - start-time
            insert pos reform ["<br>Processed in :" elapsed]
    ]
Graham

[8836x2]
Doc's debug code does that ...
so the processed in no longer works with a .html extension?
florin
25-Aug-2010
[8838]
Sure. But I am wrong? My understaning from the docs is that the app-init.r 
would inject this in every page when processed.
Graham
25-Aug-2010
[8839x2]
it should ....
and it does when you use a rsp extension

Don't you love it when it happens! I was working on the http.cfg 
file located in the cheyenne source rather then the proper one. I 
should've listened ot my wife an go to bed!
Graham

[8842]
so, we've been chatting for 45 mins because you were working on the 
wrong file???
florin
25-Aug-2010
[8843]
45 minutes? I outta go. I messed up your time.
Graham

Would you not find this web framework appealing though?
