Well, this dependes how you expect parse to work. The rule [to " - " (?? string1) | to newline] is a choice and Rebol parse uses a one-shot evaluation while parsing, this means, it executes a rule as long as possible starting with the first rule from several choices. As soon as the rule, in this case to " - " could be parsed successfully, the rule block ends. I expect parse to be in sync with the progress of the parsing. So, after parse did to " - " I expect the copy operation as terminated because internally it look like this: Copy string to " - " which can be executed successfully. So the print should succeed. The question is what is the trigger for the copy: You say it's the end of the rule block (lat trigger) and I would expect as soon as copying makes sense (early trigger). From a debugging point of view an early trigger is much more useful, further it would allow to create context-sensitive grammars, as you could chnage parsing rules on the fly.

[REBOL] REBOL/Core 2.5.3 Released
A new REBOL/Core has been released for testing purposes. Check out the list of changes and find out where to get it at: http://www.reboltech.com/downloads/changes.html Some of the changes include: MAKE-DIR Rewritten New Bitset Functions: CLEAR, LENGTH?, EMPTY? Changes to SKIP Function ARRAYs Initialized with Block Values Added PARSE BREAK Word Fix to OPEN on Network Ports Fixed Crash on Modified Functions Unset Object Variables (on Exit) Added BUILD-MARKUP Function Revised BUILD-TAG Function Revised DECODE-CGI Function and more... Some of the changes to functions like BUILD-TAG might be worth discussing... because the old function was pretty bad, and the new one is not that compatible with it (if anyone was in fact using the old one.) Let me know what you think. There's more to do, but we didn't want to hold up some of the nicer changes to wait for everything. Newer versions of /View, /Command, /Encap, /Link, and /Serve will be made available soon. -Carl REBOL Guy -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.

Yeah, for me, anyways. Further down, I'm nested some 6 times, and that's
leaving a ton of white space and extraneous scrolling past the edge. For
readability, I always indent whenever a new block is opened.

Thanks, for the thousandth time, to everyone who's responded. I will be
taking all of your suggestions into consideration.
Er, that sounds like the response to a job application. What I mean is,
I've spent the past, hm, 6 years working in this one language which is rather
C-like, but it's not C - it's an interpreted language in a specific development
environment. In it, I could do things like:
for line in text {
if blank line {
continue;
// makes the for loop go to the next line
}
everything else
}
So, I could use 'break' to cancel the for entirely, or use 'continue' to
just skip on by. I have come into the habit of frequently using if blocks at
the beginning of functions to test various conditions for which other blocks of
code should be ignored. Ie, if the line is blank, skip it all. Further down,
it checks if the line is commented; skip everything else, then. Otherwise, do
everything else.
I think that Gabriele's idea of setting up another function is what I will
most likely have to do. Oh well - that main function was getting awful hefty
anyways ;) Thanks folks.

Hi Robert, I run your code and I get an error straight away: ** Script Error: string1 has no value ** Where: rejoin ** Near: mold name: get name So you probably had string1 set before you ran your test code. > rule1: [start: copy string1 [to " - " (?? string1) | to newline] copy > string2 to end] To start, lets just look at the first COPY in your Rule1. The variable is string1, the pattern is [to " - " (?? string1) | to newline] Rule1 looks bad to me because you are asking parse to COPY the input stream matched by the pattern into string1, but then from inside the pattern (and therefore before the pattern completes) you try to print string1. So the short answer to your first question is - nothing has been copied to string1 by the time you want to print it from inside the rule. > - After the parsing string1 holds what I did expect in the > first place too. This indicates that the varaibles input > gets copied to will be changed after the parsing. But when and how? When the pattern completes (after the first ] ). Compare with this: >> parse/all "this is a - parsing test" [copy string1 to " - " (?? string1)] string1: "this is a" == false In this case the pattern is just to "- " and so copy has finished by the time string1 is printed. > Rule2: > - This time the string1 is as expected inside the rule but > changes to include the to " - " sequence after the parsing > > Any idea what's up here?

From: "Charles"
Howdy folks. Got a bit of a difficulty here. Say I'm evaluating a for
loop, like reading lines of text from a file. At the beginning of my for
loop,
I have it check to see if the line is commented, blank, or neither. If it's
commented or blank, I want it to just skip to the next iteration of the for
loop; however, if it's neither, let it keep going. I would prefer to do
this
with a simple if [] as opposed to a heavy either [][]... 'break' doesn't do
what I need - it kills the for loop entirely, instead of skipping to the
next
iteration. If I use either [][], I have to do:
either condition? [
if true do this
][
if false
do these
next 20 lines
all indented
with more indentation
yet to come
very long lines
]
You follow me? It's a coding habit I've picked up from another language.

The rule states 'to and not 'thru? IMO string1 should be "this is a" - After the parsing string1 holds what I did expect in the first place too.

Copy&paste the > entire block of code with the suggested change before loading my actual script? > What if one were to simply (in post m11480) replace the code which causes REBOL > to dump on circ forward and instead carry on? Hi, Charles, There are at least two ways to achieve the change mentioned by Maarten in the archived email. One way is to create your own copy of the http scheme, edit it with your favorite text editor, then load the scheme into REBOL. One way to do this is to: 1) Open fresh REBOL console 2) Type "echo %/path/to/a/file/my-http.r" and return key 3) Type "probe system/schemes/http" and return key 4) Type "quit" and return key Then go to the directory where you choose to save the file, and open the file with your favorite text editor. Remove the ">>" at the beginning of the file and insert "system/schemes/http:" just before the word "make". Then remove the ">>" from the end of the file and save. This is the RT version of the http scheme. Now, scanning down the file, locate the 'handler object, then the 'open function within the 'handler object, then the 'forward block in 'open. Toward the end of this block, you will see the line that Maarten referred to "build-port". Following this line, insert that line that he recommended trying: http-get-header/host: port/host then save the altered scheme. Now at a fresh REBOL console, load that scheme with something like do %/path/to/a/file/my-http.r Note, that this method *replaces* the default scheme with your new http scheme in the current session only. Now work on the circular forwarding problem to your heart's content. The alternative approach to "patching" REBOL requires some trial and error. In my version of REBOL/View, the following will locate the scheme as it exists at runtime and insert the desired line directly: insert next find second get in system/schemes/http/handler 'open 'build-port reduce [to-set-word "http-get-header/host" 'port/host] Watch for the line wrap (this should all be on one line in the script or console). In addition to trial and error, this method is also potentially more fragile, hence some people's preference to copy the scheme to a file and make changes there. >Even better, though, would be to take this first address, perform... I don't > know, SOME function on it to find out what the REAL URL should be, and let me > access that - server and subdirs all together. I would really like to try and > do this without messing with system functions... *sighs* There is a way to capture the information that you seek by directly using the ports, but my guess is that you will end up with a less flexible reimplementation of what is already a part of the http scheme. You can of course hack the http scheme protocol to capture the information during processing, but you might as well add the functionality you seek right into the scheme in use, or you will find yourself having to "always" make at least two calls for each url access (first to find if it is forwarded then a second call to the next url). Maarten's basic approach is to let the scheme automatically manage a forwarding request, but as he implies, it may not be fully tested. It has been over a year since I played with a forwarding problem. If his suggested addition does not accomplish your need, let the list know, along with the url, and we may be able to hack a more robust patch. Hope this helps. --Scott Jones -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.

I should have written something more like that I agreed that it certainly wasn't obvious what was going on.

I also should clarify at this point that I, too, am not a AIX/unix/*nix dude, but I played one at an improv theater once. (<< Attempt-At-Humor Alert >>) So like all good actors, then I'm probably over qualified. :-) Actually I don't think that this is an AIX issue, or I wouldn't be wasting your time. Just that in being a close follower of the list, I've noticed certain recurring patterns of problems. This one *appears* to be a requires-some-sort-of-authentication-that-is-not-fully-supported category, which can be further subcategorized into a using-a-"non-standard"-user-account-name or using-one-of-the-many-non-standardized-authenticated-smtp issues. > >telnet smtprelay.avnet.com:25 > >type: > >EHLO your-client-url > >and return and wait to see if amongst the return messages you see: > >S: 250-AUTH=LOGIN > > > I'll try it, but I'm not sure what you mean by "your-client-url"? Do you > mean the url of the box I'm trying to email from? Please clarify... I guess that was a bit nebulous. Sorry. As Anton pointed out in a separate response, it may not matter what is typed in here because many email servers will determine what it needs, namely your machine's URL, and therefore, your machine's IP. Assuming that you are emailing from within the network (which I assume you are since I cannot ping nor telnet to your server from the Internet), your client url would likely look something like "dana.avnet.com" or maybe "dana.bestdivision.avnet.com". The email server will then get the IP address that belongs to this url. My foggy-headed understanding of this is that some email servers can be configured to only accept email from within certain subnets as a further means of avoiding the unintended hosting of a promiscuous email server (I just love that expression). Further authentication is a redunduncy added in case the url/ip has been spoofed, or authentication can be used to accept email from outside the subnet or network (like if you are working from home), in which case the url/ip is unimportant, but the user account name and password is crucial to avoid being a promiscuous email server (there's that expression again). Since you didn't mention having a user account name that includes an @ (like [EMAIL PROTECTED]) and that you use (or will be using) Exchange server, then you may wish to try the hack I made April '01 for Nick Carson. http://www.escribe.com/internet/rebol/m7905.html In this solution, I provide two scripts that add hacked versions of the smtp scheme and the send function. Watch for line breaks. I renamed these to avoid any conflict with REBOL's official version, but can be named to overwrite the default code. As it stands, these scripts are designed to be run from a REBOL console, but can be easily rewritten to run as a /View gui. The authenticating username and password are requested from the console prompt on first use, and stored internally for the rest of the session. These values are not saved to permanent storage locally for security reasons. Please note that if this script is to be provided for multiple user use, it would be trivial to halt a script then hack and get the username and password once entered (meaning, security risk). If this is the situation, then the scripts should be changed to ask for the username/password *each time* needed. If these scripts do not work, then I would try the telnet route. From Windows, open a dos box and type in: telnet smtprelay.avnet.com 25 After the email server responds, type EHLO your-client-url-as-discussed-above then see what returns. This return infomation will be very valuable for determining what to do next in making REBOL compatible. You may sign-off the telnet session with "QUIT" and return. (BTW, if you cannot see what you type, then in the telnet menu, click preferences, and select "local echo".) I hope I have further clarified what was evidently a less than clear explanation. I'm interested in hearing what you find. --Scott Jones -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the qu

How about this while [ it is true ] [ catch [ if condition1 [ do something throw ] if condition2 [ do it too throw ] do something else ] ] or just use switch as it is mostly suitable.

[REBOL] Re: PC Uptime
Good! How portable is OpenGL ? I got interested in SDL - Simple DirectMedia Layer http://www.libsdl.org/intro/toc.html SDL is a free cross-platform multi-media development API . It's currently ported to Linux Win32 BeOS MacOS, MacOS/X but I only did some simple tests to see if I could call a routine! I wanted to use SDL for graphics. I'll probably get back into it some time, so then I'd be very interested how you got the pointer to the face frame buffer.

[REBOL] Re: Email woes on IBM/AIX Risc 6000
Hi Ed, Ed> connecting to: smtprelay.avnet.com Ed> ** Access Error: Network timeout Ed> ** Where: confirm Ed> ** Near: smtp-port: open [scheme: 'smtp] Ed> if email? I had something like this once. The problem was due to the mail server attempting to do an ident check on the machine which was talking to it. The timeout period of this on the mail server was longer than the default timeout period in Rebol. The solution was to turn the ident request off on the mail server although if you have no access to that you should be able to increase the Rebol timeout value instead.
