World: r3wp

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 :(

sorry to add junk, but I *really* think this group should be renamed 
(this is On Topic :-)  

probably !REBOL2-release or something like that.


its too easy to mistake right now with !REBOL3 being such an active 
group.

Requested.

Done.

Thanks :)

If I want to set something to the index of a series, or something 
else if it's not there I have to do this

b: either a: find series var [
	index? a
][ 	default ]

when I'd rather do

 b: any [ index? find series var default ]

So how about letting index? also take none as an argument ?

b: any [ attempt [ index? find series var ] default ]

funny thing is, that the former code is exactly as long as the latter 
one, does not need the additional variable, and it is faster

...and I find it more readable

yep, no need for additional var.

all [b: find series var b: index? b]

oups, not what you'he done

indeed, I just meant:

b: either b: find series var [index? b] [default]

I'm pretty sure I'd be ok with  NONE == INDEX? NONE

That kind of change is not going into R2 - it's not backwards-compatible. 
Try R3.

But it's easy enough to create a safe INDEX? function. I think Gabriele 
calls his INDEX?? and I borrowed it from him.

that's another issue .. how to easily redefine words

that also invoke the original word ....
