World: r3wp

I would not trust R3's parse for now. It's buggy and changing.

ok, and for my paragraphs ?

I suggest you take a look at the makedoc parser. it does exactly 
that. I'm not sure how to solve that problem.

Ok, thanks for the tip.

kib, you write:

title: [ 1 6 "=" copy title to newline ]


In that, you use the word title for two things, so you destroy your 
intention. Change one of them to another word (remember to do it 
again further down your code).

Geomol: my fault, thanks a lot! I didn't notice I've used "title" 
for 2 different purpose. Changing the variable name solved the issue.

:-) You're welcome!

I really enjoy playing with Rebol

Me 2!

I mean I never saw something so 1/ simple and 2/ powerful

You might wanna use TRIM with your titles.

Neither did all of us here. That's why we use REBOL.

Ok, I just checked TRIM : that's useful.

I've somewhat modified the TextMate bundle for REBOL for e TextEditor, 
and made a new theme for it : http://tinyurl.com/dxt89p. I someone 
is interested, let me now.

I played with the TextMate bundle at one point (when I had a mac 
running here), and I think Will Arp or Chris Ross-Gill have also 
done some work on it.

And, yes, REBOL is wonderfully addictive. :-)

There is a bug in an older version of the textmate bundle, causing 
textmate to very quickly fill an error log with megabytes of errors.

Help! : how can I use parse to handle this case: a match will starts 
at  "//" only if the char before "//" is not ":" (like in "http:://www...") 
?

Henrik: how do you raise such errors ?

kib2: I never entirely found out, but I think it could have been 
when it was trying to syntax highlight empty brackets: []

Henrik: no problem for me inside eTextEditor. I've also noticed that 
the textmate bundle missed several keywords (ie the ones from the 
parse dialect).

valid-start-char: complement ":"
valid-start: [opt valid-start-char "//"]

>> X: complement {:}
== "
>> length? X
== 1
>> X/1
== #"

This looks like a bug to me

What version of rebol, on what platform?

On linux, I get
>> x/1
== #"?"

Aha. In Rebol3 string! and char! were removed from COMPLEMENT allowed 
arg types.

Rebol/View 2.7.6.4.2, on Ubuntu linux

>> X: complement ":"
== "Å"
For me :
>> length? X
== 1
>> X/1
== #"Å"

On Windows Seven with RebolView 2.7.6.3.1

do you mean:
 valid-start-char: complement charset ":"

Oldes: you're right !

I have a question for you rebol experts :)

How would you make simple app like this:

Open window with 100x100 pixels and lets say control individual pixels 
on that window.... something like direct screen buffer - one pixel 
= one byte in an array...

what would be the "Rebol way" ?

Do you really need low-level access ? I suppose you don't mean simply 
this?

view window: layout [my-image: image (make image! 100x100) button 
"set pixel" [my-image/image/(random 100x100): white show my-image]]

I ask this because I want to try effect for demo that uses some math 
functions to draw pixels on certain coordinates....

what you wrote is just the thing I need! :) didnt know Image had 
that effect...  :)

have to go to lunch.... :) Thanks Anton!

Try also:

img: make image! 300x200
window: layout [size (img/size)]
window/image: img
view window

(Less faces in the resulting face hierarchy, so should be more efficient 
to redraw.)

how would you combine those two examples?

I did it.... :)img: make image! 320x200
window: layout [size (img/size + 100)
				button "set-pixel" [window/image/(random 100x100): white
									show window]
			   ]
window/image: img
view window

thanks Anton... this is perfect for what I want to do..... :)

nice example

oldes. yes, with practice, my typing has improved from dropping letters 
to dropping words.

In addition to poking pixels, don't forget the DRAW effect.

.. and the DRAW function.

draw img [line 0x0 300x200]

(DRAW is not good at setting individual pixels, though.)
