Can anyone explain this?  Is this expected or a bug?

Save the following data out to a file (I used territory.txt)...

What is it about the first row of data in particular it starting 
with a string that prevents the parsing of the carriage return ("^/") 
to not work?

It may be a recurrence of a problem parsing " at the beginning of 
a line -- doesn't seem to be a problem on the beta that I have open 
(1.2.54).  As an alternative, you could always read/lines, or simply 
load the file...

It's a bug, as I see it.

and what do you do if the text is not a file ?  Write your own parse 
rule.

1.2.57
>> parse/all {"a""b""c"de} "e"
== ["a" "b" "c" "d"]
Please, add the bug to RAMBO.

How do you break a parse rule and still have it be true ?

Actually, what I was wondering was how to break out of an action 
in a rule and still let it return true

In a paren, you can change a 'break-rule from an empty block to [to 
end], then include that break-rule in your main parse-rule somewhere.

(for a more backwards compatible solution)

Oh dear, looks like my memory was not so great. I was using 'break 
in the early-exit rule here:

extract-link-by-name: func ["Returns the first A link with the specified 
text in the source string."
	name [any-string!] "link text"
	str [any-string!] "html source string"
	/local start end terms non-terms link text early-exit
][
	early-exit: []
	if parse/all str [
		some [
			thru "<a " any " " 
			["name" | [
				"href" any " " "=" any " "

    [{"} (terms: {"}) | (terms: " >")] ; set terms depending on how url 
    starts, with double-quote?
				(non-terms: complement charset terms)
				start: some non-terms end: (link: copy/part start end)
				opt {"} any " "
				thru ">" copy text to "</a" ; <- was before just "<"
				(if text = name [early-exit: [to end break]])
			]]
			early-exit
		]
	][reduce ['link link 'name text]]
]

Ah, here is an example of what I was thinking:

>> rule: [] parse "aaabbbb" [any [rule ["a" (print 'a) | "b" (print 
'b rule: [to end " "])]] to end]
a
a
a
b
== true

When the first b is encountered, rule is set to a rule which cannot 
be succeed, thus breaking out of the outer any.

The email is obtained by reading from a port in binary mode, so could 
this be due to the lack of line ending conversion ?

From a unix system to windows32?

Hi Graham. Line ending in Internet protocols = Apples; Line/Paragraph 
representation in text files = Oranges. :-)

Best not to compare them for this task.  As far as I've seen, Internet 
protocols have an on-the-wire line ending of CRLF.  So yes this is 
very likely a problem with your parse rules.

Hi Brett.  Do you then see a problem with me parse rules?

unix would be a single "^J"

yes ,  my rule was for a single lin as in your first code  sample

mac is a single ^M for a single line

;I tend to use charsets as a way of skipping 'thru while looking 
for multiple possibilities:
line-end: charset [#"^/" #"^M"] ; etc
line: complement newlines

parse m [copy header [some [some line line-end]]]

a way of skipping
 -> "an alternative to"

That means any character that isn't a line-ending...

line-end: charset [#"^/" #"^M" #"^J"]
line: complement line-end
parse m [copy header [some [some line line-end]] to end]

; Note that 'line-end in the parse line should be replaced with permutations 
of what a line-ending can be, without describing any permutation 
of a double line-ending.

I'll give this one a go as well.

Joe:   What do you need a perl comatible regular expression  to do?

It wouldn't have to be industrial-strength, but it would like a security 
blanket for developers experimenting with the new language. PCRE 
is found all over the place in languages on Linux machines, and the 
absence makes some developers uncomfortable - despite the fact that 
Parse is better.

Good point. One article I was thinking would be along the lines of 
a "phrasebook", translating PCRE concepts to Parse equivalents.

What about a parse rule that takes pcre strings as input and produces 
a parse rule as output?

I am not totatly against REs I use them all the time in shells, and 
having them built in would make writing "work alike" programs easier 
but over all , it  seems to me like a step down

I will be a few to make concreat but basicly you work with what is 
common to all lines , in this case colons and newlines

sorry, I missed a problem in this expression: the header must start 
with a newline, so
parse header [header-rule some [thru "^/" header-rule]]
is better

Ahh...well, invariablly the first line of the header is "Return-path:" 
so i'ts not a problem.

I need the "^/... as nowadays, there's email coming thru with authentication 
signatures that contain the headers in a block

if you came accross a novel header line before you came across  the 
To: line you would not get to the To: line

this header-rule should now be applied each time I get  a "^/" ...

I hate when the "network" brings applications to a halt.

Terry - in a good way? :-) Reichart is rich man, he has experience 
with business, he contracts many rebol developers already :-)

My point is.. is Rebol going corporate.. with a particular agenda.. 
(ie: Microsoft).. or leaning towards open source.. this is a serious 
question.

Terry: basically, Safeworlds will offer a product, AltME 3, that 
replaces View, IOS and AltMe 1. That is a product and so is more 
business targeted.

RT, instead, focuses on the language itself, and the language has 
a lot of parts that are open source.

the core itself is still proprietary (a 200k dll so far)

There can be a conflict of interest

RT is interested in developing the language REBOL. Safwerolds is 
interested in developing the product AltMe 3. their iinterests converge 
a lot. there's mainly just a difference of focus.

So Altme3 is the new view?  You don't see a conflict there?

How can there be a conflict in a free marketplace?

I understand the financial aspect.. and the free market aspect.  
 Is Rebol turning into an application, more than a language the Im 
to build a company on?

Carl said he'll discuss R3 licensing/pricing later.. let's hope for 
some fresh air in this area, or I'm afraid R3 will become a specialty 
application for a very narrow user base, with a specific agenda.
3:20 a.m. here.. signing off.. enjoy the rest of the conference.

I'm riding my bicycle with some friends in about 4 hours...at a place 
that two days ago all burned.  We lost something like 300 hectacres.

Los Angeles lost a HUGE resource, Grifith Park burned to the ground.

Gabriele - in what way is AltME a virtual OS?

The idea is to open source a lot, and just keep the low level stuff 
closed, but RT will post something official.

Why not? rebol.dll was already out there on the net with plug-in. 
Jaime posted interface - you could pass it a string with rebol code, 
no?

I'm a bit confused that REBOL/View == AltME now, so does it mean 
that GUI development is moved away from RT?

ie for us developers nothing changes (except for the fact that altme 
3 opens up a lot of opportunities etc)

don't - even i don't speak always english... so i guess a lot of 
people here

We have considered hiring him.....but he has a first love.

It could be a job interview :-)

My vote for a name is YANSEFTL (You Are Not Smart Enough For This 
Language)

How about a language that changes pronoun.  I program in ME, it can 
amazing things for YOU.

That could be just a clever ploy in today's world.

Carl's comments on merging of VID dialect and global namespace. It 
took me a long while to learn it, but I appreciate it more and more.

well it's supposed to be a quick lunch

Right, 2 hours is a quick lunch in France...

I got a few hours of sleep earlier....so I'm up for the next 20 hours 
or so.

Free wine?!?  Don't let Carl near it, he will start comparing it 
to his own Vineyards...and it will be a 3-4 hour lunch!

Some how I think this group can handle a lot of wine...

We're closed for lunch now.

Back in a Parisian hour for Carl speaking on: "The Motivation for 
R3"

Sorry, no, a "hot mic" is a mic that swings with volume level...so 
when there are sharp increases in sound, it clips.

A good trick is to put foam over the mic.

first post is one on a hot mic.

obviously there must be a solution to this problem already, but I'm 
just thinking two mics, one soft, one loud, and a "compressor" box 
that selects the loudest signal which does not clip.

Actually, up until a few years ago (when mics got a lot better) they 
used to have foam covers.

So you still get a good effect with a new mic ? Do you think the 
devcon mic is a new one or old one ?

ok, so even a newer mic can be helped with foam in this situation.

A big glass room is a nightmare for sound.

Yes, putting foam over the mic would help a little, but it would 
also mean that it would not work as well iat a distance.  What you 
really want is a mic wired on the person (which has foam built in), 
 and no mic on the room.

I think there is often a problem with the sound being too strained, 
as if you're holding your nose while talking or it sounds like you 
have a cold. Mine suffers from that, as well as not handling the 
pronounciation of P sounds properly.

A directional mic on the person.

It is actually a omni directional I think, but has a peak range of 
1 meter.

It is called a Lanier Mic

Henrik, that sounds like it doesn't have a good response. Have you 
checked a frequency response.

I bought a really cheap mic recently - I think it was $3 - and the 
frequency range is abysmal.

Mics have dropped in price, just like optics for cameras...but $3 
is still TOO CHEAP.  Pay $50+ and you will get a good mic.  I always 
trust Plantronics for headsets.

the Lanier mic obviously has a tight dynamic range.

They dropped in price ($299) so you can get them now for probably 
$200+, which is a great deal.

They also have a -35 dB drop, so they REALLY work well on Planes.

My name should get caught in your throat like a a painful peice of 
dry food...

philB, look closely. he's holding a PSP :-)

or maybe typing onto a PDA

wish we had a PS3 that small !!

Watching this on Safari/Quicktime I get sound and a green image?

And that he has a name badge!!!!

Ah.. le son a cessé

oh goody a secret context !

that sounded like a challenge  :-)

docs? what'a that?

(btw docbase is already running, as carl said this morning, and carl 
has been writing a lot of things in it.)

considers allowing object! to define the port handler... like a feel.. 
.MUCH easier to Tweak and scan handler
