[!Cheyenne] Discussions about the Cheyenne Web Server

| BrianH 4-Jan-2011 [9473] | Cool, those sound useful. |
| Kaj 4-Jan-2011 [9474] | There's nothing complex about keeping promises |
| Dockimbel 4-Jan-2011 [9475] | Andreas: I share your feeling. I guess that it's easier and safer to add a new native in R2 than integrate all that stuff into system:// port (using set-modes/get-modes as interfaces). |
| BrianH 4-Jan-2011 [9476] | I am in favor of releasing Pro as Core and just disabling the licensing code; that would give us Library on Core a lot quicker than trying to retrofit things into Core. R2 is quite an old codebase, so a lot of changes would require a huge amount of work - R3 was rewritten for good reasons. |
| Andreas 4-Jan-2011 [9477] | Probably time to move this discussion to !REBOL2 Releases. |
| amacleod 6-Jan-2011 [9478x2] | I can't get cheyenne to serve to an ajax json request. I can get it to read the array as a local file but it does not seem to work through url request. I played with content-type: application/json which I read was needed but I don't know if I'm on the right track. |
For example:
json data:
{
"foo": "The quick brown fox jumps over the lazy dog.",
"bar": "ABCDEFG",
"baz": [52, 97]
}
and the js script to fetch the data:
<script>$.getJSON('http://localhost.jsontest.cgi', function(data)
{
alert("JSON Data: " + data.foo);
});</script>
| |
| GrahamC 6-Jan-2011 [9480] | It works fine for me I have in my RSP pages Print json-data |
| Dockimbel 7-Jan-2011 [9481] | This doesn't look like a valid URL: 'http://localhost.jsontest.cgi' |
| shadwolf 7-Jan-2011 [9482] | should be http://localhost/jsontest.cgino ? |
| amacleod 7-Jan-2011 [9483x2] | yes...i just typed it here wrong....thanks |
my local script:
<!DOCTYPE html>
<html>
<head>
<style>img{ height: 100px; float: left; }</style>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<script>$.getJSON("http://localhost/jsontest.cgi”, function(data)
{
alert("JSON Data: " + data.foo);
});</script>
</body>
</html>
my rebol cgi script:
#!/cgi-bin/rebol.exe -cs %s %s
REBOL [Title: "json test"]
Print {
<html>
<head>
<title></title>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
</head>
<body>
{
"foo": "The quick brown fox jumps over the lazy dog.",
"bar": "ABCDEFG",
"baz": [52, 97]
}
</body>
</html>
}

| PeterWood 7-Jan-2011 [9485] | Alan, I'm logged in to AltME from Ubuntu - so many non-ascii characters get displayed incorrectly. In your script the closing double-quote after /jsontest.cgi doesn't display properly. Perhaps you could check that it really is a double-quote and not a "smart-quote" in the actual source. |
| Dockimbel 7-Jan-2011 [9486] | Amacleod: Your CGI script headers looks very wrong: - What are those "%s" on the shebang line? - /cgi-bin/rebol.exe: this doesn't look like a valid filesystem path - Why the Content-Type header isn't emitted as required by CGI specification? Maybe you should read again documentation about REBOL CGI usage on rebol.com site and also have a look at CGI sample scripts provided with Cheyenne source package. Understanding what a shebang line is might also help: http://en.wikipedia.org/wiki/Shebang_(Unix) |
| amacleod 7-Jan-2011 [9487x2] | When i go to the cgi script directly in the browser I get my json data displayed. the cgi seems to be working. |
- Why the Content-Type header isn't emitted as required by CGI specification? not sure what this means.. | |
| Dockimbel 7-Jan-2011 [9489] | Amacleod: while [not understood?][read http://www.rebol.com/docs/core23/rebolcore-13.html#section-13] |
| GrahamC 7-Jan-2011 [9490] | alan, if you use getJson, you expect to see an application/json header. So, try just $.get instead .... |
| amacleod 7-Jan-2011 [9491] | That worked. I get the alert but there is an error that "data" (my variable) is undefined. Can I use use the application/json header and if so what is the syntax...do I just replace the the "text/html" string? |
| Oldes 7-Jan-2011 [9492] | I guess you should print only the JSON data, not html page! |
| amacleod 7-Jan-2011 [9493x2] | that works, Olds! thanks alot. |
only works local though...does not seem to read from remote server | |
| Oldes 7-Jan-2011 [9495] | what kind of server? |
| amacleod 7-Jan-2011 [9496] | windows |
| Oldes 7-Jan-2011 [9497] | I mean url |
| amacleod 7-Jan-2011 [9498x2] | I can see the data when I url the cgi script directly so cgi is working... |
bighousefdny.com/cgi-test/jsontest2.r | |
| Oldes 7-Jan-2011 [9500x2] | And what does not work? Btw.. are you setting the content type? |
use at beginning: print "Content-Type: application/json^/" | |
| GrahamC 7-Jan-2011 [9502x5] | No, you can't use remote server .. this is a security feature. |
The json data has to be from the same server as the source web page | |
You need to use JSONP for cross site scripting | |
Additional Notes: Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, or protocol. Script and JSONP requests are not subject to the same origin policy restrictions. | |
Anyway, we are now off topic for Cheyenne | |
| amacleod 7-Jan-2011 [9507] | Sorry, I thought it might be a cheyenne issue...i'll move to javascript group |
| GrahamC 5-Feb-2011 [9508x2] | Longshot here .. but has anyone written a code formatter for RSP pages .. so that it correctly indents HTML, JS, and Rebol all on the same page?? |
there's a php pretty print here http://beta.phpformatter.com/ | |
| Kaj 5-Feb-2011 [9510] | That's one reason to write as little code as possible in templates |
| MikeL 6-Feb-2011 [9511] |
Graham: I am happy using Andrew's ML.r with Cheyenne to implement
Don't Repeat Yourself on the few pages that I do. <%
include %ml.inc ; does [%pop.r %push.r %build-tag.r %ml.r] which
can be pre-loaded
print ml compose/deep [
h1 "Heading"
p {Text paragraph}
p (now)
]
%>

| Dockimbel 28-Feb-2011 [9512] | Cheyenne's ReBorCon presentation now also available in PDF format. The files used for the webapp coding demo have been published too: http://cheyenne-server.org/blog.rsp?view=25 |
| Kaj 28-Feb-2011 [9513] | Thanks, Doc! |
| Claude 28-Feb-2011 [9514] | thanks you ;-) |
| Dockimbel 3-Mar-2011 [9515x2] | Cheyenne reached a new milestone, as promised during the ReBorCon, 0.9.20 is out! Read the announcement here: http://cheyenne-server.org/blog.rsp?view=26 All the new binaries are built using REBOL 2.7.8, enjoy! |
The web site has been updated too, new documentations for Cheyenne are pending (will be available tonight). | |
| james_nak 3-Mar-2011 [9517] | Doc, thanks. Can you check the Window's binary links? |
| Dockimbel 3-Mar-2011 [9518x3] | Broken links, fixing that... |
Done. | |
Thanks James. | |
| james_nak 3-Mar-2011 [9521x2] | Thanks. |
Doc, I'm thinking this version fixed my cookie issue with Curecode . We'll see. So far it looks great. Merci. | |
