World: r3wp

Don't worry, we are also focused on the core of R3 :)

R3 plan for February - http://www.rebol.com/article/0389.html

very good summary!

I ported my CMS to R3

The results are not very encouraging

It´s written in a simple style, yet I had to make a series of tweaks

I encountered several bugs and I had to write a series of wrappers 
for READ and WRITE to arrive at functions that act compatible between 
R2 and R3

Eventually, when I built a number of OpenOffice XML files that take 
three seconds on R2, it took twenty seconds

Is there any reason that R3 would be extremely slow under WINE?

Please post any bugs you find in CureCode. There are some changes 
in the way READ and WRITE work though.

I can't test in WINE, so any bug tickets would be appreciated.

Actually, I hit another bug that makes it impossible to port my CMS

In R2, dir? tests the file node to see if it´s a directory or just 
a file. However, in R3, dir? works like file? and only tests whether 
the value ends with a #¨ /¨

This leaves no way to detect an actual directory

alpha software is out there to be stressed

One doesn't really expect it to work ....

Did I say otherwise?

Yes.  You're implying it.

No, I´m not

Perhaps not consciously... but that's how it appears to me.

Are you a brain doctor?

Kaj, can you post some code which breaks DIR?

Just human

Why don't you just port dir? func from r2?

.... it is a mezzanine, you need to port throw-on-error to be compatible 
...

¨ dir? anything¨

interesting... dir? works fine here.

Thanks, Petr, that should work

ah, I get it now

but it does test correctly for existing directories. it's a little 
ambiguous, but testing also for EXISTS? could help

You sure??

>> dir? %asdfsdf/
== false

it seems it will do this:

- it tests FALSE for an existing file
- it tests FALSE for an existing file and adding a /

- it tests TRUE for a non-existing dir with an ending / <-- bogus?
- it tests TRUE for an existing dir with an ending /
- it tests TRUE for an existing dir without an ending /

crap ... had wrong version of rebol up

the bogus one would be eliminated with an EXISTS?. still it's a simpler 
way to test for non-existing dirs, say in preferences files for paths 
and some basic syntax checking.

but you also have to check the ending / if you want to form paths

in R2, we have to do the "#"/" = last file" check

annoying ...

so, I think there should be a function for that, but having it in 
DIR? may be ambiguous.

I'm adding a ticket, just to be sure.

So, we need a function that both checks that file exists, and it's 
a directory?

so... there should not be a need to port the R2 one, just ask like 
this:

all [
	exists? file
	dir? file
]

That shouldn't hurt the R2 version.

Even info?/type is incompatible. ´directory for R2 and ´dir for R3

probably related to ports being different in R3. I'll make a ticket.

The exists? check is insufficient, because it will return true if 
a regular file exists but the value is written in dir form with a 
trailing /

exists? %/c/msdos.sys
== true

exists? %/c/msdos.sys/
== false

or is it R2? checking...

ah, yes. there is an issue in R2.

The issue is in R3

The above code was pasted from R3.
