World: r3wp

how things are now, HTTP is (mis)used in varioius ways, and you have 
to handle the exceptional cases yourself.

don't you agree, that the way R3 handles the issue is the best way? 
R2 can probably be made to behave similarly. (I've actually been 
thinking of backporting R3's HTTP for a long time...)

I don't know how R3 handles http .. not looked at it.

I guess I just don't like the idea of a protocol hiding data from 
me,...

what's the difference between 'join and 'rejoin ?

The number of args:
    join "a" ["b" "c"]
    rejoin ["a" "b" "c"]

>> text: "hello world"
== "hello world"
>> bin: make binary! 1
== #{}
>> join text bin
== "hello world"
>> rejoin [ text bin ]
== "hello world#{}"

JOIN takes 2 parameters, REJOIN just takes one, and is slightly slower 
because it has to retrieve the first parameter from what would be 
the second parameter of JOIN.

A different outcome.

Looks like a bug to me, Graham.

Opinions?

Looks like a bug to me too.

R2 work around?
    to-string rejoin [#{} "hello" #{}]
    == "hello"

not for me .. thanks!

I was constructing a payload for a http post, and need a combination 
of string and binary data.  I used rejoin... and got an unexpected 
outcome.

So, I guess I'll just have to use repeated appends instead to build 
the payload.

ajoin: funco [
	"Reduces and joins a block of values into a new string."
	[throw]
	block [block!]
][
	make string! reduce block
]

Faster than JOIN or REJOIN.

Sorry about the funco, I copied that from R2/Forward.

let me guess .. part of your rebol3 backport ??

Of course.

does it build a series without corrupting binary data ??

perhaps i need 'bjoin :)

Yes. The mezzanine is faster than the native version, but the native 
doesn't have the intermediate block overhead.

Where is it?

'funco i.e.

It's just another name for FUNC (where FUNC is redefined in R2/Forward).

ask-brian: funco [ ask-brian ]

oops... missing the second block!

Just use FUNC :)

Nope... seems to give the same problems as rejoin

ajoin: func [[throw!] block [block!]][make string! reduce block]
>> ajoin [ "hello" make binary! 1 ]
== "hello#{}"

apologies .. Sunanda's workround works  viz to-string rejoin [ #{} 
.... ]

Wow, that make string! change to join/rejoin yields about a 300% 
speed increase! Definiately one to backport to R2.

doesn't help with 'ajoin though ... need to coerce to binary first

Graham -- glad the workaround  works.
But it is R2 only. R3 has other problems.

not too fast .. it exhibits different behaviours

Just needs a bit of datatype coercing added.

this has always got me
 rejoin [ <text> "hello" </text> ]
== <texthello</text>>

rejoin [ "" <text> "hello" </text> ]
== "<text>hello</text>"

which is I guess one should use 'reform when constructing strings 
for web output.

this fix allows me to upload a binary document using the googleapi 
.. eg. docx

First cut QAD on join/rejoin, still about twice as fast the originals:

	join: make function! [
		"Concatenates values."
		value "Base value"
		rest "Value or block of values"
	][
		either series? value [
			make type? value reduce [value rest]
		][
			make string! reduce [value rest]
		]
	]


	rejoin: make function! [
		"Reduces and joins a block of values."
		block [block!] "Values to reduce and join"
	][
		either empty? block: reduce block [block] [

   make either series? first block [type? first block] [string!] block
		]

	]

try rejoin with using #{} as the first element!

Ashley, that JOIN doesn't work for block types. It should be:
>> join [a b] [1 2]
== [a b 1 2]
Yours returns  [[a b] [1 2]]]

Anyone can tell me why my googledocs object won't clone?

http://rebol.wik.is/Googledocs

gdoc: make object! googledocs []
** Script Error: Invalid argument: object
** Near: gdoc: make object! googledocs []

crap

still asleep ...

Has anyone done any work with OAUTH ie. open authentication?

REPEAT is a native. Can it be made as a mezzanine using WHILE? It 
takes 3 arguments:
'word value body


The first is seen as a lit-word by the function. This should be bound 
to body and only be used as a local variable in the function context. 
My first attemp to make a REPEAT mezzanine didn't go well:

my-repeat: func [
	'word value body
][
	bind/copy body word
	word: 0
	while [(word: word + 1) <= value] body
]

>> my-repeat i 10 [print i]
** Script Error: i has no value

Suggestions?
