[REBOL] Re: No-wait
Paul Tretter napsal(a): Yeah this was my current work around to use 0 as a timeout but I was a wondering why it was needed if there was no-wait. It was not imo. Your code was imo wrong for what you wanted to achieve: port: open/direct/no-wait tcp://:7000 x: 0 forever [ print x + 1 x: x + 1 data: first wait port ] Do you know what above code is basically doing? You opened so called listen socket - TCP channel assigned to you by OS. That kind of socket is able to accept new connections, nothing more. One there is new client asking for connection, it simply assigns it other type of socket, so called communication socket. Just look at 'probe of given port and look for 'local-port item - that is the port assigned to you by OS. So basically - what did you expect your above code will do? I think I can tell you :-) Your 'forever loop will hang on, untill there is new connection coming. Just open second console and type-in: client: open tcp://127.0.0.1:7000 and your 'x will counter will be raised by 1 - You created nothing more, than connection counter. For that, you choosed wrong name 'data. I would suggest: console1: - server: open/direct/no-wait tcp://:7000 conn: first wait server forever [ wait conn data: copy conn print mold data ] console2: - client: open tcp://127.0.0.1:7000 data: read %user.r forever [ insert client data wait 5 ] Just copy and paste and watch your simple client/server communication you can put your console code in another loop, which will be able to accept several connection, wait on list of clients connected and voila, - you've got your tcp multiplexing engine running.

[REBOL] [ANN] [REBOL.org] Packages -- first release
Thanks again to everyone who helped field-test some of the concepts in packages last week. Packages are now live on REBOL.org --- any Library member is free to contribute packages if you want. Please do! ** What's a package? ** Up until now, the Script Library has only really worked for single, stand-alone scripts. Support for packages makes it much more flexible. A package is a collection of files that together make up an application. There are up to three parts to a package: 1. the header script -- what you see if you view the script (or search the Library). In most cases this will be just a stub (it'll be the instructions for downloading the package). See: http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=lds-demo1-pack age.r as an example 2. files -- files that form part of the package. The package owner will upload these. 3. other scripts -- other scripts from the Library that the package needs -- e.g. values.r or map.r. No need to upload these (they are already there). The owner simply has to mark them as being part of the package. ** Why contribute packages? ** 1. Undying gratitude of everyone that uses your work 2. Way to distribute your work without needing to set up your own website 3. Way for non-reb users to find and use your work. 4. Useful mirror even if you have your own website ** Notes for potential package owners ** -- Logon and select contribute new package from the control panel, You'll be stepped through the process. -- You can add or remove files and scripts from a package at any point -- You can share the package with other users -- useful if a couple of people are collaborating on a development -- The package stats page gives you useful counts of how often the files in the package have been downloaded. ** Package downloader ** There was lots of useful, feedback last week on platform incompatibilities and UI oddities. Thanks again for all that. Most of the worst problems are fixed, but it'll be another week before we tackle the other issues. ** To find out what packages there are ** http://www.rebol.org/cgi-bin/cgiwrap/rebol/search.r?filter=type-package View the script, and then click the Package Info link to see what files make up the package. ** Any problems? ** Just let me know -- either here or using the REBOL.org Feedback page. Thanks all! Sunanda. -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

I don't like word-fragmentation ;-) Choosing the right words for things is very important, I agree. Apologies if I've not choose exactly the right one. But package has a venerable history in this context -- at least 40 years, I'd guess. And fileset is not quite right either. An IOS fileset will synchronise both ways (you change the file, I get a new copy. I change the file, you get a new copy). A package is dumber than that. If I change a file in a package I own, the next time you download it, you will get the new copy. But, whatever you do to that copy -- short of emailing it to me -- I won't even know. The synchronisation is one way only. But yes, the IT world has way too many words for things that are almost the same. When I do mainframe work, I talk about data sets whose content lives on DASD and are updated via access methods. When I work in REBOL it's files on a hard disk updated via ports. Of course, a data set is not the same as a file, DASD is a wider concept than hard disk, and an access method is not the same as a port. But they are close enough not to really need different words.

[REBOL] Can I define an anti function?
Doc draw my attention to the %subject%, which was discussed at

{Suppose f is a function returning a boolean.Is there a way of defining
a function anti, which, when given f, returns not f?}
the discussion continued:
{
(define (anti f)
(lambda args
(not (apply f args

hardly any other languages can do.
}
{
This last statement is a bit too strong, even in Python you can do
Sheesh, I clearly said hardly any other languages, not no other
languages. I stand by my original statement -- most programming
languages can't do this. Python and Scheme are some of the few that
can. C can do it for functions of a specific arity, but can't
generalize (e.g. you can write anti_f1 for 1-argument functions, anti_f2
for 2-argument functions, etc.)
}
{
I expect most general-purpose dynamically typed languages can, at least
those using a conventional syntax. Perl can, Ruby can (but its treatment
of higher orded functions is weird), Dylan can, and probably all Lisp
variants too.
Smalltalk can't because variable arity doesn't make sense: the method name
implies the arity syntactically. Rebol probably can't: here the arity of a
function tells how many words to parse as its argument and where the next
function call begins. Forth and Postscript can't.

Use 'wait on the server port with a timeout value (e.g. 0.02) if you don't want to block while waiting for a client to connect. -- Best regards, Andreas -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject. --- Outgoing mail is certified Virus Free.

[REBOL] Time, seconds and scientific notation
Hallvard Ystad wrote.. apparently on 23-Feb-2004/21:00:15+1:00 Hi list, This is from a console session: third 0:00:01.09 == 1.09 third 0:00:0.09 == 9E-2 How can I have the second example printed without scientific notation (as seconds)?
