[REBOL] recommend a REB friendly host Re:(4)
I know much more things than you about the server that host my site
(thor.prohosting.com) because I wrote a CGI script that let me browse the
filesystem of the server, and view the error log file of the server. But
this didn't helped me.
REBOL returns an error code of 1 or 2 when I remotely run it.
I checked 3 times that I uploaded the BSDI version ("uname -a" says "BSD/OS
thor.prohosting.com 3.1 BSDI BSD/OS 3.1 Kernel #0: Thu Jan 28 00:02:17 MST
1999 [EMAIL PROTECTED]:/usr/src/sys/compile/THOR i386").
It seems to me that thor.prohosting.com has a different configuration than
your server :(
(my home directory is in /usr/home where yours is in /usr/home2, for
example).

[REBOL] rebol and SSL Re:
The problem with REBOL and SSL is that REBOL can not yet download files using the HTTPS protocol (URLs that begin with https://). This is a problem if you want to develop a web client script that need to talk with a securised web server. But in your case you don't care because you are developping CGI scripts. This the job of the web server that hosts your CGI to do the SSL encryption/decryption to talk with the browser of the customer.

Hi folks, Over the weekend I was playing with the REBOL money! datatype and discovered some problems. Using the REBOL/Core console: x: $10 == $10.00 y: x + .01 == $10.01 y - x == $0.00 ;surprising result, displayed value is not correctly rounded We can check what is happening by retreiving the decimal value from the money values: dx: second x == 10 dy: second y == 10.01 dy - dx == 9.79E-3 ;this is the actual numeric value of y - x, it should round to .01 The problem seems to be incorrect or absent rounding of the difference: to-money dy - dx == $0.00 Checking when to-money will return .01 vs .00: a: to-money "9.99934E-3" == $0.00 b: to-money "9.99935E-3" == $0.01 Clearly both of these values should round to $.01. There some other anomalies also: (y - x) * 1.01 == $0.00 (y - x) * 1.1 == $0.01 (y - x) * 10;displayed result is wrong by a factor of ten == $0.01 (y - x) * 100 ;displayed result is correct == $1.00 These problems are not due to the round-off intrinsic to decimal values. Even in the worst case we have 15 significant digits of precision. The example shows incorrect rounding in the 4th significant digit. I wonder whether others have noticed this problem? Note: this has been CC'd to feedback as a bug. Cheers Larry

[REBOL] [BUG] unset! (and help function lie!) Re:
- Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Monday, February 28, 2000 3:41 AM Subject: [REBOL] [BUG] unset! (and "help" function lie!) Hi Olivier, you wrote: So unset! seems to be a datatype. Lets verify if unset! is a datatype : type? file! == datatype! type? unset! ** Script Error: unset! has no value. ** Where: type? unset! One of REBOL's most confusing issues is that representations of some values look exactly like the words they are assigned to. These values cannot be directly parsed by REBOL - first they are parsed to words, and then the word is evaluated. When you did: type? file! == datatype! REBOL first parsed the string you typed, "file!", to the word file!, and then when that word is used as the argument of TYPE? it is evaluated. The word FILE! is preset to the datatype! file!, which is the value that the function TYPE? sees. I had no problem with that. My point was that unset! is not preset to any value. [...] Now the problem with unset! is that there is no word set to the value unset! . This is easily fixed: unset: (type?) == unset! type? unset! == datatype! Of course. I should have thought to this. I put the paren around type? because if you do this in a script TYPE? will take the value of whatever is next, but the paren prevents TYPE? from seeing anything else. You also wrote: type? file! == datatype! help file! file! is word of value: file This not ok! It seems inconsistent, but this is the result of a REBOL trick. HELP has a special way of specifying its argument: I'm writing this kind of messages to [EMAIL PROTECTED] not to get a work-around, but for them to make it consistent while REBOL is still not widely spread. help: func [ "Prints information about words and values." 'word [any-type!] /local value args item refmode types ][ snip ] The argument is specified as a lit-word! (by using the ' ). This specifies that if the argument is actually a word, that word is to be unevaluated. Thanks for this explanation. Passing parameters as lit-word! is a very cool feature. That is, HELP wants to see the word itself, not what the word is set to. This way you can use HELP to test if a word is set to a value: help grog No information on grog (word has no value) Otherwise, trying to evaluate the word grog would result in an error before HELP even had a chance to see it. So, if you want to get help on the value that the word is set to, try this: help (file!) file! is datatype help file! file! is word of value: file Putting the word file! in a paren prevents HELP from seeing it as a word. So the paren is evaluated, the datatype! file! comes out, and HELP tells you that the datatype! file! is a datatype. We also get the same result with the following the ':' operator : help :file! file! is datatype This is what I expected from help file! (without using :) I just wanted that they modify the 'help' function to be more informative about datatypes. One other little issue here is that there are two ways of representing a value, forming and molding. Molding is better in that it gives you a string that REBOL can use to get back the original value, but forming is supposed to be easier on the eye. HELP forms the values, which is why you lose the ! 's. See you, Eric With all those good explanations on the heart of the language, it's now time for me to re-read the REBOL user guide from the beginning, to understand every feature. Thanks Eric.
[REBOL] Split-path correction Re:
From: [EMAIL PROTECTED]
Hi,
after having some problems with split-path, here is my version:
(Andrew, it may be nice to have it in your %patch.r)
Not yet, Andrew !
split-path: func [
{
Splits a file or URL. Returns a block containing path and
target.
Not always. It has other bugs than the original.
It breaks the splitting of URLs (I called your version split-path2) :
split-path http://fgdfgdfg.Fgdfg/fgdfgdfg/dfgdfg
== [http://fgdfgdfg.Fgdfg/fgdfgdfg/ %dfgdfg]
split-path2 http://fgdfgdfg.Fgdfg/fgdfgdfg/dfgdfg
== [http://fgdfgdfg.Fgdfg/fgdfgdfg/ dfgdfg]
Overcomes some limitations of the Core split-path like
strange results for:
split-path %file.r
split-path %dir/
split-path to file! ""
The last expression can also be written like that :
split-path %""
Moreover, the identity:
file = (append copy first r: split-path file second r)
is always preserved.
Remember that you can have a look to the source of the original split-path
to improve it :
source split-path

[REBOL] Split-path correction Re:(2)
Andrew Martin wrote: [EMAIL PROTECTED] wrote: split-path %file.r split-path %dir/ These ones, I feel, aren't a problem. The existing implementation of split-path is correct, I believe. There is a problem. Look at the type of the second element of the result : split-path %fdgd/file.r == [%fdgd/ %file.r] split-path %file.r == [%./ "file.r"] In one case it is a string!, in the other it is a file!. There is also others problems with the original split-path: split-path http://www.rebol.com == [http:// %www.rebol.com] split-path http://www.rebol.com/ == [http:// %www.rebol.com/] I would prefer to get == [http://www.rebol.com/ none] in both cases, as in the following: split-path %/ == [%/ none] To summarize, split-path is so inconsistent that I will never use the current version for real work. clean-path is as buggy (even more) : clean-path http://www/dfhfgh/../fghfgh == http://www/dfhfgh/../fghfgh (doesn't remove . and .. in URLs) clean-path %"" ** Script Error: Out of range or past end. ** Where: first target-copy What would be cool, in fact would be a reference test suite for every function of REBOL. Every Perl module provide such tests to assure consistence between platforms. It seems that Rebol (the company) doesn't use such methods to assure code quality. But it's not too late to take another way than Microsoft's. Olivier.
[REBOL] [BUG] unset!

Lets verify if unset! is a datatype : type? file! == datatype! type? unset! ** Script Error: unset! has no value. ** Where: type? unset! But : type? type? %f == datatype! type? type? == datatype!

[REBOL] Precision in fractionnal numbers
I wrote before on the mailing list ([EMAIL PROTECTED]) about the importance of precision when manipulating money values. Money values are currently handled with floating point values stored in base 2. I'm trying to produce a sample of how this internal design might result in wrong results. I didn't found one yet with money values, but here is one with date values : d: now == 19-Feb-2000/18:43:56+1:00 d/time/second: 29.456 == 18:43:29.45599 This test was running on the Win32 platform. As you can see, the output is not the same as the input. This is due to the fact that the input (29.456) is converted from decimal to binary for storage, then from binary to decimal for output. One thing that too many programmers ignore is that conversion of fractionnal numbers may result in losing precision when converting from decimal to binary or from binary to decimal. For date value, I don't care because I don't plan to use so small values of time. But I repeat that precision is the most important thing when dealing with money values. Olivier Mengué
