World: r3wp

But, in the case of a lack of documentation: I'm in a hurry, more 
often than I want to be, having to implement something that needs 
to be used in a few hours, and so I don't want to spend hours studying 
the source code, no matter how self-explanatory, the author claims 
the software is.

To use async on R2, I used to use Uniserve engine.

Once upon a time, France used a Web forum that had an XMLRPC interface 
and I coded a Rebol client that was able to monitor activity and 
send post on the forum asynchronously. It was a happy time...

and why doesn't it work anymore?

I remember that  ...

But using the Uniserve engine seems overkill :)

Maxim : the web site is dead ! So the script is useless now !

ah well.

Oldes, indeed, one should pass CALL a block and let it do the conversion 
(because it is platform dependent) - though right now I don't think 
it does much more than to-local-file and adding quotes.

I have updated str-enc-utils.r at rebol.org with the bug fix that 
Henrik kindly provided.

sort function can sort  pairs but < and > leads error? don't you 
think it would be better if < gives same result with sort?
sort [10x4 23x2]
>> [23x2 10x4] ;sorted y-first
10x4 > 23x2
>> ** Script Error: Expected one of: pair! - not: pair!
and it is a little bit strange error, expects pair, not pair?

yes, that error is not good, see the R3, where the error is:

>> 10x4 > 23x2
** Script error: cannot compare pair! with pair!
** Where: >
** Near: > 23x2

Sortability and sort order are (in REBOL) distinct from comparability.
See this curecode report and the response for example:
   http://curecode.org/rebol3/ticket.rsp?id=1150

in the #1150 the response is missing the point, as I see it, mistaking 
#[datatype! unset!] and #[unset!]

sort order for different datatypes is a more complex issue, but comparing 
pair to pair should be consistent with sort I guess.

I mean
= 4x3 4x3
>> true
< 4x3 4x3
>> error

What do you think about this:

>> even? 2.1
== true


As far as I am concerned, I would call it a bug, since 2.1 does not 
look like an integer multiple of 2.0 to me.

Unsure if it's a bug or I'm not getting something: http://stackoverflow.com/questions/3068467/why-cant-i-bind-things-like-email-in-the-global-context-on-interpreter-startup

In the VM I'm running, AltME messed up the link again after email-in-t.

hmm, another reason why not to manipulate words using strings; if 
you used words, you would not have observed any strangenesses

what needs to be answered is *why* you had to (?) use the string?

Yes he would have - the problem was independent of using the string. 
But it would have been less obvious if he had used a word from the 
beginning. Good opportunity for an object lesson though: He was asking 
about a "global context" in R3.

>> is-email-addr: get bind 'email? bind? 'system

(just works, no strangenesses)

Ah, but that is assuming that the code is run at the top level. Judging 
by that particular code snippet, it looks like something from inside 
a function, and one that is likely in a context has 'email? already 
defined. Still, the fact that INTERN is already run on normal scripts 
(and the module equivalent run on modules) means that he likely wouldn't 
need to do this with the main contexts, just inner contexts.

did you mean this?


>> f: func [/local email?] [is-email-addr: get bind 'email? bind? 
'system]
>> f

Yeah, something like that. I added a question about using words instead 
of strings.

so, I have to insist, that everybody using strings instead of words 
deserves every disaster he gets for not adhering to documented "best 
practices"

Those who don't use LOAD are condemned to reinvent it, badly :)

Has to do with implementation of this function: http://github.com/hostilefork/Rebmu/blob/master/rebmu.r#L448

Instead of [REMAP-DATATYPE email! email? "em"] I'd like [REMAP-DATATYPE 
email! "em"], but was confounded in trying to figure out how to write 
a version of that which worked reliably.

just BTW, an expression like

    is-email-addr: get bind load "email?" bind? 'system

can be expressed using a shorter form

    is-email-addr: get bind load "email?" 'system

, which is, in fact, the same, as:

    is-email-addr: get load "email?"

this is something curious I just noticed.

If you pass a file as a parameter to a rebol program on the dos command 
line it works
but if you do the same in a dos batch file, it does not

eg:. script.exe %/c/rebol/myfile.dat

works from the dos command line

but to get it to work in a batch file you have to do this

script.exe %%/c/rebol/myfile.dat

I presume it's because the command processor tries to do a substitution 
using the %

That would be it.

%
 is the variable begin/end tag. ie:
	C:\> set directory=c:\windows
	C:\> dir %directory%


But in batch file, it's also the begin tag for a "number" variable 
equal to the n'th parameter of the script. %1 for first param, %2 
for second... ie:
	C:\> type mybatch.bat
	dir %1

	C:\> mybatch.bat c:\windows

So, is there any other way to escape the % ?

I though escape char was ^, so let's try "^%"

Not in a batch file .. doesn't work

that's the Rebol escape char

%% is a typical answer, since doubling the escape/meta character 
is usually sensible.  Well, to the extent that batch files are sensible.

I guess it was a good guess then :)

>> f: func[][ print "kuk" make error! "bla"]  f
kuk
** User Error: bla
** Near: make error! "bla"


Is there any way how to get something more useful in the "Near:" 
part of the user error?

This will get you a "near f" message and an arg1 code of 404, but 
 not an error of type 'user --- is that more useful?
    f: func[][ print "kuk" make error! 404]
    if error? bad: try [f] [probe disarm bad]

no... it isn't. the neer is again just [make error! 404]
