World: r3wp

Huh.  Looks like it's marking the end of the block without actually 
removing elements, so that they're still accessible if really needed.

>> A: [a b c d e]
== [a b c d e]
>> path A 3      
>> ? A
A is a block of value: [a b]
>> A/2
== b
>> A/3
>> A/4
== d
>> mold A        
== "[a b]"
>> back tail A
== [e]
>> back back tail A
== [d e]
>> back back back tail A
== []
>> back back back back tail A
== [b]


I can see myself using this...  And I think I'd actually had a problem 
a while back where it would have been helpful.

Im iterating over a lines in a file , with this line in a foreach 
body

if find tempLine "//Database " <> none [ print "Here" print line 
 ]

but the print line is printing [ true; ] instead of the actual line 
?

oh hmm, im splitting by lines with this -> lines: parse (read to-file 
rejoin [ moduleName ".php" ]) "^/" , but it seems to be splitting 
by spaces ?

parse/all

that works, but the find function doesnt seem to be working, the 
two lines it returns for matching //Database are var $new_schema 
= true; and case 'ACL': return true; ---

those are the only two lines that have true in them

use braquets

if (find tempLine "//Database ")  <> none [ print "Here" print line 
 ]

and remove (<> none), it's useless

argh , cant wrap my head around these damn precendence rules

if find tempLine "//Database "  [ print "Here" print line  ]

can you explain why the brackets work ?

because "//Database " <> none is first evaluated

return always true

so, in realty , you do a find templine true

and why is that evaluated first, I thought things were left to right 
?  YOu know where in the manual i can re-read this ?

no

all op! are evaluated first

i don't no for the manual

*know

thx for your help -- the manual desperately needs a search function

CharlesS, if you changed the equation to;

if none <> find tempLine "//Databases" [...] this would also work.

the find in this case would be evaluated first, prior to the op!. 
 Unfortunately I don't know where I read this but I know i've seen 
lots of code where the equation portion of the condition is followed 
by the condition itself  ie, if 2 = 5-3 [do this].  It's backwards 
to what you would expect, but follows with the right to left evaluation 
that occures.

PATH is just not supposed to be used :) it is there by mistake afaik.

it's there so we've got something to fiddle with and don't ask about 
new releases too much ;)

;)

I wonder what is 2.7 good for, as R3 official release is at DevCon, 
and it is less than 3 months? ;-)

i guess people won't start using r3 in production that soon.

Pekr it's official preview and not release

how comes? Official alpha was supposed to be out 3/4 year ago :-)

maybe R3 is little bit delayed because 3D Realms addopted it as a 
main programming language for Duke Nukem Forever? ;P

I think R3 is not really delayed... I think the plan has simply changed, 
and this time Carl is finally working at delivering what he promised 
at devcon 2004.  He might have realised that its a little bit more 
work to make something so open... you can't hide the ugly things, 
so I'm pretty sure he is doing a lot of cleaning up...  and we have 
been hearing about the fact that this time, view isnt' being left 
behind...

Rebolek :-)))

Maxim - hopefully you are right!

I'm OK with R3 release date, but just couldn't resist to make that 
dukenukem joke :)

rebpro does not contain core stuff? so no decode-cgi for e.g.?

you mean rebol/view pro?

or some sdk build?

no, rebpro I placed on server .... as I needed library access, but 
this time it does not contain decode-cgi, uh, I will have to generate 
my own rebol.exe with features I want?

I vote once again for pad function!

I just needed very simple function, which will return me 20070220 
... so I want to write something like:

join now/year [padl now/month "0" 2 padl now/day "0" 2]

Instead of writing some stupid 'either lenth? code ...

>> 0.0002
== 2E-4

It may be old, but how do you avoid this conversion_

we have other trivial mezzanines, why not something like 'pad? Who 
writes the simplest code for me ;-)

yes Henrik, that is just another "stupidity"

put it in challenge :)

pekr, I vote for pad too, only because I've written that function, 
oh, about 50 times now.

I had function somewhere, parsing E-+value, and generating string.
