World: r4wp

This looks like Cheyenne-dependent code...

But, you should *really* use a async HTTP client, that's the best 
solution for your need (multiple HTTP downloads at the same time).

hmmm. ok...will work on this and get back to you
thanks for the time Doc

(cant wait to see Cheyenne on Red ;)

Well, you might see some micro-Cheyenne before Christmas. ;-)

best christmas ever!

just to persist with using uniserve...i think something i may be 
getting there

uniserve-path: %./
== %./
>> do %uni-engine.r
Script: "UniServe kernel" (17-Jan-2010)
Script: "Encap virtual filesystem" (21-Sep-2009)
== true
>> uniserve/boot
booya
127.0.0.1
127.0.0.1
== none
>>

i commented out the lines from on-started:

on-started: has [file][
		worker-args: reform [

   "-worker" mold any [in uniserve/shared 'server-ports port-id]		;TBD: 
   fix shared object issues
		]
		if not encap? [
			append worker-args reform [" -up" mold uniserve-path]
			if value? 'modules-path [
				append worker-args reform [" -mp" mold modules-path]
			]
			if all [
				uniserve/shared
				;file: uniserve/shared/conf-file 
			][		
				;append worker-args reform [" -cf" mold file]
			]
		]
		if integer? shared/pool-start [loop shared/pool-start [fork]]
	]

...since conf-file is cheyenne specific


i think maybe the scheduler is killing UniServe - it exits while 
returning none...

nope - the scheduler is just fine...

i'm now thinking it may have to do with using the shared/do-task 
in the on-load function...

nope
will take doc's advice and do something simpler

If you're using R3 or Red/System, you could use the cURL binding 
in multi-mode

Sujoy: have a look at this description of  one of async HTTP clients 
available: http://stackoverflow.com/questions/1653969/rebol-multitasking-with-async-why-do-i-get-invalid-port-spec

Doc, I reported that problem before remember? we were agreed on the 
fix:

in task-master.r

line 135: if all [ uniserve/shared in uniserve/shared 'conf-file 
file: uniserve/shared/conf-file ][
	 append worker-args reform [" -cf" mold file] ]

and on line 123: all [ in uniserve/shared 'server-ports uniserve/shared/server-ports 
]


Endo: "without these patches latest UniServe cannot be used alone. 
because it fails to start task-master. Ofcourse I need to remove 
logger, MTA etc. services." - 19-Dec-2011 2:50:29
Dockimbel: "I agree about your changes." - 19-Dec-2011 2:50:56

I think it is the same problem for Sujoy. (better to move Cheyenne 
group)

Thanks Endo...I am still keen on using uniserve - will get there 
eventually!

i have another issue - and need help from a parse guru

i'm trying to extract article text from an awfully written series 
of html pages - one sample:


http://www.business-standard.com/india/news/vadra-/a-little-helpmy-friends//489109/

there are 160 </table> tags!!
worse, article contents are scattered throughout the html mess

using beautifulsoup in python however, i can do the following:

from bs4 import  BeautifulSoup as bs
import urllib2


uri = "http://www.business-standard.com/india/news/vadra-/a-little-helpmy-friends//489109/"
soup = bs(urllib2.urlopen(uri).read())

p = soup.find_all('p')
[s.extract() for s in soup.p.find_all('table')]
[s.extract() for s in soup.p.find_all('script')]
[s.extract() for s in soup.p.find_all('tstyle')]

text = bs(''.join(str(p))).get_text()

...and this gives me exactly what is required...

just want to do this in Rebol! ;)

just a quick answer, to give you an idea, I've used following to 
extract something from a web page:
b: [] parse/all mypage [
        any [

            thru {<span class="dblClickSpan"} thru ">" copy t to </span>
            (append b trim/lines t) 7 skip
        ]
 ]

7 skip
 is to skip </span> tag.

yeah - thanks Endo

that works great for well formed html docs - but this site is an 
absolute nightmare!

I've used the HTML parser from PowerMezz to parse complex web pages 
like that

note from the python code that there are styles and javascript specified 
inside the <p> element!
i was wondering about Gabrielle's HTML niwashi tree

never used the niwashi - Kaj, do you have a quick example for me 
to use?

i've got the docs open, but am maybe being obtuse - it is 230am here!

It's a bit confusing to set up. I'll have a look

thanks Kaj

That came out bigger than planned. I was trying to cut out some repetitive 
fields. It scrapes addresses from a web page and converts them to 
text format

whoa!

but i get the idea

Yeah, not very competitive with the BS code

well...the bs lib gzipped is 128kb...

and python is ~30MB
but yeah - its a lovely piece of work

Still looks like it would be nice to have a REBOL implementation 
:-)

yes it certainly would

Kaj: 
love your r2 bindings for zeromq 
i've been trying to implement the push-pull ventilator example

ventilator:
REBOL []

do %zmq.r

pool: zmq/new-pool 1
socket: zmq/open pool zmq/push
zmq/serve socket tcp://*:5555

ventilate: func[][
  print "sending"
  u: form time/now/precise
  zmq/send socket to-binary u 0
]

wait 0:00:60 [
  ventilate
]

worker:
REBOL []

do %zmq.r

pool: zmq/new-pool 1
socket: zmq/open pool zmq/pull
zmq/connect socket tcp://*:5555

data: copy #{}

forever [
  zmq/receive socket data 0
  prin ["."] 
  print to-string data
]

...but the worker crashes

any idea why?

the weather update server works just fine...

Please excuse my ignorance but has rebol been open sourced yet?

Nicolas, the license is still being discussed.

Thanks. That's what I suspected but I wasn't sure.

Excited?

Well, it will be interesting to see if we can finally get some movement 
on it, but Red is getting rather distracting.

Yeah, I'm playing with it now.

Still. I'm pretty excited to see the code.

Sujoy, I only did a request/reply example so far, so I'll have to 
look into it

Thanks Kaj

i need to be able to get rebol working with push-pull, so i can get 
apps running behind zed shaw's mongrel2 server

there's nothing better than rebol for parsing - and i want to keep 
using rebol
any help hugely appreciated!

I'm running Mongrel since several weeks, with Cheyenne and Fossil 
behind it

cool! so you have the mongrel pushing requests to Cheyenne?
