Benjamin 4-Oct-2005 [1237] | ax: make struct! [fnc [callback!]]none ax/fnc <---- this hangs up rebol with a GPF error. |
Volker 4-Oct-2005 [1238x2] | rebol callback -> http://www.rebol.net/article/0141.html |
sorry, wrong group. | |
Benjamin 6-Oct-2005 [1240] | that damm article, yes i've read it too many times maybe... ok what about this a: make struct! [x [integer!] y [integer!] z [struct! [ xy [integer!] yx [integer!]]]] none length? third a == 12 <--- it has 4 integers thats 16 not 12 ! what about 0141.html now ???? |
Volker 6-Oct-2005 [1241] | xy is a pointer to a struct, nt the struct itself.. sadyl we lack nested structs. |
Benjamin 6-Oct-2005 [1242x2] | yes it's a pointer to the struct, a workaround my be done because you can know how many intems are including the nested one's, and as far i can see rebol assigns 4 bytes for all datatypes meaning strings and nested structures ar also pointers |
you can use size: (length? second a) * 4 it may fail :-) | |
Volker 6-Oct-2005 [1244] | yes, all pointers. workaround for amll structs is: z [integer!] z1 [integer!] ; in the main stuct. for other things you can try binaries and deal with offsets. or write a wrapper in c. |
Benjamin 6-Oct-2005 [1245] | yes that's execly what im doing ;-) i send a number to C it read n data from the pointer and then passes to rebol as a string the i use Romanos's wraper to cast that into a structure; but i get ocational crashes when reading fron a crazy pointer :-) i consider this a hack, but still may work ... |
Volker 6-Oct-2005 [1246x2] | attention: pointers in structs are considered strings. they are copied back *until* a 0 is found. |
workaround: use two references: rebol-ref: make binary! 1234 struct/pointer: rebol-ref then access things thru rebol-ref | |
Benjamin 6-Oct-2005 [1248] | yes thats why im sending the amount of bytes to read back to the C wraper still it gave me a haed hache lol |
Pekr 6-Oct-2005 [1249x2] | if I would even understand what you are talking about, guys :-) |
so you trying to say, that if there is struct inside a struct, you don't use it, you just provide it with "flat" binary, and then you compose things back in rebol level? Why is that better than using structs in structs? | |
Benjamin 6-Oct-2005 [1251] | well realy the thing is... did you remember that windows sometimes adresses structures in window messages like lparam or wparam, so i get the nasty number, and i've to buil a structure back from this *pointer*,..... because i do drugs :-) |
Volker 6-Oct-2005 [1252x2] | well, you cant see what we do, because we crawling under the cars engine here ;) but yes, you are right. its because rebol has no inner structs. when you declare them, it actually allocates a pointer there. thats fine with own code. but os expects real inner struct, so we have to workaround to allocate the right space. |
but if you can code c, i would do all the os-coding in c then, and use rebol-structs only for pasing between rebol and my c. gives os-includes without any pain, much easier. | |
Pekr 6-Oct-2005 [1254] | coding in C stinks .... I don't wanna carry C compiler with myself, unless included in Rebol ;-) Librry interface should be enhanced then. What about trying to post a wish into RAMBO? |
Benjamin 6-Oct-2005 [1255x2] | some years ago i've used a realy cool compiler rapidq the bastard dident have the posibility to pass structures back that time i used this kind of workaround |
what do you mean ? | |
Pekr 6-Oct-2005 [1257] | I don't even know what do I mean. The only thing I know is that I find wrapping libraries not all that comfort and I would like to ask those having experience with Python,Perl or any other language, if they have some easier way of how to do that or not ... |
Volker 6-Oct-2005 [1258] | c-compiler costs me ~4mb if it is a big one. and a good interface needs processing includes. basically that *is* a c-compiler included in rebol then ;) |
Pekr 6-Oct-2005 [1259x2] | Maybe the trouble is really in me and not being able to properly do datatype conversion and all those structure wrappings etc. |
well then, so big :-) | |
Benjamin 6-Oct-2005 [1261] | yes i know what you mean i put = in rebol and : in C also i get lots of sintax error mising semicolon.... wrapers stink |
Volker 6-Oct-2005 [1262x2] | No, the problem is rebol has a good c-interface and a pretty good with some meta-programming. (to avoid this double-declaration in rebol and c). but it has a terrible os-interface (by lack of full c-structs and includes). if you accet that and interface onyl to your code, its wonderfull (as wonderfull as c can be). |
then you write lots of little accessor-function to pick things out of os-structures. sounds terrible, but actually all 1-liners. | |
Benjamin 6-Oct-2005 [1264] | c has a verry strong type checking thats cool for some cross over plattaform but wen it comes to rebol interface you get mad ... |
Volker 6-Oct-2005 [1265] | if you try to mimic c-structures. if you create c from rebol-structes, it acceptable. maybe does not really check parameter-types, IIRC. but not sure, i rarely need rebol<->c and more rarely make that error. |
Volker 8-Oct-2005 [1266x2] | Is this wine or real windows too? >> to-money 0.09 == $9.00 wrong with everything with leading zeros. does not happen on linux. to-money 1.09 works ok. Does money string-based conversion and sees windows 9.0000000e-02? 1.09 looks like 1.09000000e+00, so fraction-part is behind ".". |
is a conversion-error, $1 is greater than to-money 0.09 . | |
Sunanda 8-Oct-2005 [1268] | Works fine under various windows' rebol.exe on my machine. >> to-money 0.09 == $0.09 |
Volker 8-Oct-2005 [1269] | thanks. then wine-bug. |
Tomc 8-Oct-2005 [1270] | works fine on solaris |
Rondon 11-Oct-2005 [1271x11] | Hi Folks |
I think that the http scheme the temporary redirection .. server error 307 is not at the rebol http_scheme.. the 302 is.. but not the 307.. | |
if you try: page: read http://www1.folha.uol.com.br/fsp/opiniao/fz1010200501.htm | |
it will redirect you to another url from the browser.. | |
but using Rebol, you can't get this new url.. as you could using page: open http://www1.folha.uol.com.br/fsp/opiniao/fz1010200501.htm | |
print page/url or page/target | |
you know.. ;) | |
I think that the same procedure for 302 should be for the 307 server error | |
if you call from a browser it will redirect you to the following url: https://acesso.uol.com.br/login.html?dest=CONTENT&url=http://www1.folha.uol.com.br/fsp/opiniao/fz1010200501.htm&COD_PRODUTO=7 | |
just for reference... http://ppewww.ph.gla.ac.uk/~flavell/www/post-redirect.html | |
I think 307 is not returning the alternative URL.. you know.. | |
Allen 11-Oct-2005 [1282] | RFC 2616 10.3.8 307 Temporary Redirect The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field. The temporary URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s) , since many pre-HTTP/1.1 user agents do not understand the 307 status. Therefore, the note SHOULD contain the information necessary for a user to repeat the original request on the new URI. If the 307 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. |
Rondon 11-Oct-2005 [1283] | So.. How Can I solve this Allen? |
