World: r3wp

I was on graham's side, but I've changed ideas since I've been using 
pairs for so may purposes that its really hard to find a default. 
  especially one which doesn't require different meanings for none 
and false.

but if a default where to be chosen, I'd says inside/outside would 
be the most logical.

I'd prefer area under the xy axis

as default

pair is two dimensional, so having a >< which is obviously a two-dimension 
equivalent to a linear equation would fit the bill.

I don't even see the use for area.  what would it really be used 
for?

so at least in one situation of the infinite, we don't have to write 
custom code

Max it doesn't have to have a use .. .just has to be logical

ie. there has to be an underlying logic to the choice

ah, well, why the hell implement a useless default?  really that 
defies logic  ;-)

I didn't say it was useless .. you said you couldn't think of a use 
.. quite different things

Implementing a useless default has the advantage of being the Salomonical 
solution. That way, noone has to complain if one of to sensible options 
gets implemented and you need the other, unimplemented one.

Solomon

(Not implying that the suggestes behaviour is useless)

half a baby is better than none!

We say Salomon in german, learned something new at least ;-)

I'll try and remember that when I learn German :)

Still really off-topic for this group. We're trying to keep this 
group on-topic for the discussion of R2 releases, so valuable information 
doesn't get buried in the torrent.

The is not like the !REBOL3 group, where anything R3-related is on-topic.

Was anything happening R2 wise?

We switch between R2 and R3 work. The last week has been focused 
on R3. A week-or-so ago I made a few tweaks to R2/Forward for 2.7.8, 
including a backported fix from R3, and Carl put together a plan 
and implemented a lot of his portion of the plan. I expect that soon 
after the R3 a98 release, we'll have a R2 2.7.8 release. And 2.7.8 
looks like it will be the first really stable release in the whole 
2.7.x series, something to really look forward to.

Hello, I am having a small problem about CALL:
call  reduce ["C:\Windows\hh.exe" "C:/mybook.chm"] doesn't work
call/show  reduce ["C:\Windows\hh.exe" "C:/mybook.chm"] works !
Which is the difference ?

you don't need 'reduce

call/show rejoin  ["C:\Windows\hh.exe            " "C:/mybook.chm"] 

there's a bug with 'call

Sorry, I hava modified the command. Originally I needed reduce.

well, rejoin does a reduce

The problem is different:
call/show opens the guide

call only run the task but does not open the guide. You can find 
the task in Task Manager

I think in 2.6  the behaviour of 'call changed ...

it should be fixed

hh.exe open a .CHM guide

http://www.rebol.com/article/0467.html

Read. It didn't open the child window... ok... back to work...

What's wrong here ?

rebol [
]

write %tryme.pdf
dirlist: read %//

foreach myfile dirlist [
	if find myfile ".pdf" [
		print ["Filename" myfile]
		extension: find/last/tail myfile "."
		print ["EXT" extension]
		print extension = "pdf"
	]
]
delete %tryme.pdf
halt


The comparison extension = pdf should return TRUE, instead I have 
FALSE

try 

suffix? myfile

%.pdf = suffix? myfile

I have found the function but I wish to know why te comparison fails

because myfile is of type file!, and so extension is also file!

try

print extension = %.pdf

Ok, understood. The fact I am able to start a "find" on it let me 
think it is a string...

This belongs in rebol school group

O:-)

BrianH wants to keep this group to discuss 2.7.8

I'll move there :-)

Back on pair comparisons, MIN and MAX don't return one of the given 
pair values (not sure if someone else mentioned that).

>> max 10x11 9x12
== 10x12

? 
max 10 9  = 10
max 11 12 = 12

you get the area which encloses both

And back in the Core group - we're trying to keep this group on its 
topic of R2 releases. We don't want to lose such discussions in the 
middle of discussions of semantics. The only reason this group was 
created is because some of the people working on the development 
of R2 don't want to use chat yet. This group is *only* a replacement 
for the R2-Beta world.

using MIN on offsets and MAX on size you get the enclosing box


when you use MAX on offsets and MIN on size you get the intersection 
of both boxes

I think Gregg was posting this as a bug.

This is not the R2 equivalent of the !REBOL3 group. Please don't 
abuse the fact that we can't move messages in AltME :(

I'm sorry, I don't want to be a jerk about this. This group is used 
as a reference when we do new R2 releases. It's of less value as 
a reference if off-topic stuff is overwhelming the release discussions. 
Please be nice to the R2 release manager :(
