second func [face /local var] [print face/text] ; == [print face/text]

oh?  and third is the locals ?
I was thinking it should be after third and not before :(
Ladislav

[7086]
first is the simplified spec, third is the complete spec
Graham

[7087]
ah ...
Ladislav

third was added later than first and second IIRC

What was pekr talking about regarding alpha r3 core release?
Do you know?

Graham - it was a joke. And I thought as maybe ppl would not understand, 
if I would post it in Announce group, I posted it rather in Humour 
group :-)

graham: why are you using to-block there? (my assumption is that 
you wanted to avoid the binding of load, but then you manually bind 
to the global context, so you can just use load)
a different approach is to create a context with only the words you 
want to allow, then use to-block, then bind it to your context only, 
then do it.
Ladislav

yes, the transformation to string and to block back and forth looks 
a bit messy

in-shadow-context: use first system/words['some-word]

then bind to 'some-word. somewhat  expensive, but you do it only 
on input. 

Escapes: it  does not go into #[object![..]]. I have  a function 
which does  that too.  ifthe user can do a  stringwith a new word, 
that  word is still global.
and  then fill your functions in.
use first system/words reduce[f1: (:f1) ... 'some-word]
no,  compose.

UNBIND might help handling such constructs, maybe

It would. do we have it?
I hope in  r3
Ladislav

[7106]
yes, it has been offered for R3 in a blog
Graham

Yes, I want to bind it to a different context to be safe .. so exactly 
how do I create this different context for all the math stuff?

>> a: context compose [
[    (to set-word! '+) get in system/words '+
[    ]
>> a/+

** Script Error: + expected value1 argument of type: number pair 
char money date time tuple
** Near: a/+
(don't ask me why +: is not a valid set-word)

another option:


math-words: [+ - * / ** = == =? < <= > >= and or xor square-root 
negate]
math-words: use math-words reduce [math-words]
foreach word math-words [set word get in system word]
etc.
the last line should have been:

    foreach word math-words [set word get in system/words word]

yes. but keep in mind bind ignores functions and objects, so you 
must  recurse into them too.

can anyone confirm that these two statements should return the same 
value for the same blk and val?

select blk val
second find blk val


as long as val does exist in blk.
does select reduce both args before selecting?
my god... REBOL is going nuts!  I have a situation where the above 
is not true...  and the select pairs are [aword an-object bword another-object]
and only the find works... if I try to select using 'aword   it always 
returns none
print first reduce blk

raises an error as expected since aword is not defined anywhere!
help! this is tooo strange!

relax... rebol is probably not going nuts. There is a reason somewhere.
quickly make a little example file which demonstrates the problem 
using a new console.
Maxim

[7121x3]
hehe... its just that no probing or printing reveals anything out 
of the expected.
using a new console, things behave as expected... which is why I 
am wondering why they don't in the running code
(using a block with simple values, the two lines above act as I would 
expect)
Anton

Ok, then fork the entire code and cut away chunks until it no longer 
displays the problem.
Maxim

[7125x2]
ehh impossible... we are talking bout an entire app here... 200-300kb 
of code. probably... and the problem occurs within an event loop.
but look at the simplicity of the two lines above... can you image 
a way in  which  the select would return none and the find would 
return the object?
Anton
11-Feb-2007
[7127x2]
(not impossible - that technique works when I can think of nothing 
else).
A confusion between lit-words and words maybe ?
Maxim
11-Feb-2007
[7129x2]
hum...
unfortunatetely, I can't print the block, cause the objects have 
nested objects, and that causes an out of memory err, If I try to 
mold it  :-(
Anton

write clipboard:// mold/all blk
and paste it (and mold/all VAL) into a new editor window.
Ah..
