Oldes 9-Oct-2006 [1241] | This is very good CSS tutorial, which someone may find useful - http://www.thenoodleincident.com/tutorials/box_lesson/boxes.html And this is another good place from which I found the link above - http://www.mandarindesign.com/ |
Alek_K 10-Oct-2006 [1242] | Some good resources about design/css/ia/etc. on last ALA: http://www.alistapart.com/articles/alaprimer2 |
james_nak 10-Oct-2006 [1243] | My favorite CSS examples http://www.csszengarden.comNot so much about "how" to do it but "what" can be accomplished. I find it pretty amazing. |
Janeks 23-Oct-2006 [1244x2] | I had faced with problem for file uploads: I had file upload script (upload.r posted somwhere in rebol lists/worlds) on my web servers, that works well on KF web server. But on MS IIS script hangs and I am getting timeout error from server. If it is needed I can post upload.r here! |
Actualy problem is in function read-post data - script hangs on read-io. Why it is problem for MS IIS and how to solve them? read-post-data: func [ {Reads the HTTP entity body} /safe "Disables evaluation of content-length header." /local len data tmp ] [ len: load any [ all [safe "65536"] system/options/cgi/content-length "0" ] data: make string! len tmp: make string! len while [ 0 < read-io system/ports/input tmp len ] [ insert tail data tmp clear tmp ] data ] | |
Pekr 6-Nov-2006 [1246x2] | is there any solution available for Rebol, which would handle sessions? |
My understanding is, that sessions=cookies (or hidden form field, url, or combination of those ones) plus storage/invocation mechanism | |
Rebolek 6-Nov-2006 [1248] | there is cookies manager from Oldes somewhere, have a look around AltME for URL (he still ignores rebol.org, such a bad bad bad boy ;). |
Pekr 6-Nov-2006 [1249] | cookies manager? will try to look for one :-) |
Rebolek 6-Nov-2006 [1250] | yes, it's patched HTTP scheme. Does all session management automaticaly IIRC. |
Pekr 6-Nov-2006 [1251x3] | hmm, it might not be ideal for CGI, to do 20KB script with each invocation ... |
I found it via google ... | |
well, working with cookies is not all that difficult, is it? My friend just asked me - why rebol does not handle sessions, if any other language does. I told him to write it himself, but he probably does not know how. Isn't session just about getting a cookie, looking into your storage space for the cookie identifier (session identifier), loading the session data, using them, and storing them once again? | |
Rebolek 6-Nov-2006 [1254] | Pekr: his Cookies Daemon is client-side, not server-side, I probably understood you bad. |
Pekr 6-Nov-2006 [1255] | ah, yes, I wanted server-side one ... |
Gabriele 6-Nov-2006 [1256] | Yes, session handling is not hard. REBOL does not have it built in because it was not designed to be mainly a CGI language; so you need to add that yourself. |
Pekr 7-Nov-2006 [1257] | how should I design my function, if I would like to have e.g. session: copy [] block, and later would like to append whatever rebol value into it? e.g. variable names using in script, objects, etc? when I do append session var, it stores its value .... what would be the best aproach? |
Gabriele 7-Nov-2006 [1258x3] | the simplest way, which however needs write permissions to the filesystem, is to have a unique session id assigned to users; this id could be basically a file name (and you need to check for its sanity then); then you read from the file at the beginning, and save to it at the end. |
eg. you could have session: load session-file at the beginning; then your script does whatever with session; then you save session-file session at the end. | |
temple.cgi does basically this. | |
Pekr 7-Nov-2006 [1261x2] | yes, I know, as for files. My strategy is very simple - use cookies (I wonder if there is script being able to handle multiple cookies btw), then "start a session" = generate unique ID, store it in \sessions\ dir .... |
I just thought about how to store and later load some rebol values, add new values to them ..... | |
Gabriele 7-Nov-2006 [1263] | temple.cgi uses cookies. there is no problem in handling multiple cookies on the server side, and the bug with multiple cookies on the client side has long been fixed. |
Pekr 7-Nov-2006 [1264] | maybe a pair of word name (literal) plus value ... and then some little accessor function |
Gabriele 7-Nov-2006 [1265x2] | i just let the session variable be whatever the user wants. it could be an object!, or a block!, or whatever. |
in some cases you may just need a logic! value, in others a block with words and values may be best... | |
Pekr 7-Nov-2006 [1267x2] | multiple cookies? how are they separated in http header? there are various scripts around, not sure all of them handle multiple cookies ... I will investigate ... |
ok, so you know you want to save variables: name last-name user-object some-block-here .... how do you save them, and later invoke them? | |
Gabriele 7-Nov-2006 [1269x3] | you just need to parse system/options/cgi/other-headers iirc. see temple.cgi, it shouldn't have problems with that. (but if you have session handling you only need one cookie in the end). |
allowing session handling to directly set variables is a bad design, see the plagues that php had for this. | |
just have those values inside session. that could be session/last-name for eg | |
Pekr 7-Nov-2006 [1272] | hmm, so construct an object, righ? |
Gabriele 7-Nov-2006 [1273x2] | or a block [last-name "Santilli"] |
depending on your needs :) | |
Pekr 7-Nov-2006 [1275x4] | I was really tired by Bobik, who leaving rebol just slanders it, without proper deep knowledge of what session actually is. He reported to various other friends, that Rebol is terrible, because it is the only language not actually supporting sessions. Yesterday I looked into what "sesssions" mean in php terms, and I have to laugh - for me it is matter of few hours coding at max, to get it working ... |
but that is overally problem of Rebol - while with other languages, e.g. python, he is willing to import particular library, with rebol he just states, that such a thing should be inside ... | |
while he is negative, the positive thing for me is, that his opinion means, he likes compact design of Rebol in fact, and regards it being a platform in itself :-) | |
As you mentioned Temple - it sleeps for last two or so years, or not? Is there any newer version available? | |
Gabriele 7-Nov-2006 [1279] | no new version. i don't think i'll have time for it. |
Pekr 7-Nov-2006 [1280] | working on R3, right? :-) |
Graham 7-Nov-2006 [1281x6] | your friend Bobik didn't really have a good understanding of Rebol. |
and we know that some people never get it sufficiently to be proficient enough | |
Vanilla has session support ... | |
rebol.org may as well. | |
I'm sure I read articles before on how one might do sessions server side. | |
Cheynne also has sessions ... | |
Maxim 7-Nov-2006 [1287x2] | graham, yes many people try to use a new language like they've always done before... in any C derivative that works... cause basically you aren't doing anything differerently just writting it differently (java, perl, python) but in others, you have to adapt and well... it doesn work! |
trying to use french grammar with german words... wont work, obviously. although they both have a similar male/female noun particularity. | |
Oldes 11-Nov-2006 [1289] | What's the problem with sessions? I'm not using PHP native sessions, It's just cookies anyway, you send something which identifies it on the other side. If someone say, that Rebol is bad, because there are no sessions, must be totally crazy. You don't even use cookies, you can send the id as a POST/GET variable. With Rebol I have much more control over the process. You can make SERVER in Rebol, but You cannot do that in PHP. So what, everything has it's own purpose. |
Pekr 11-Nov-2006 [1290] | I know - but then some ppl would have to understand what is behind the sessions - and there really is not magic :-) |
