World: r3wp

Ingo I made simple test and it seems it's something like 512

x: copy [] loop 1000 [append x 1] i: 0 rule: [number! (i: i + 1 print 
i) rule] parse x rule

<Slaps his head> Thanks! I could have thought about just trying it 
myself ;-)

Well, I'll have to try to rewrite the parse rules, then. 512 is by 
far not enough in this case.

the parse limit it will vary with platform

arrg not awake ... recursion limit

make that parse recursion limit, the limit on recursions for functions 
is a _lot_ higher (at least on winxp, view 1.3.1)

I have some problems to translate RULE based on PERL  regular expression 
to rebol parse rules. Maybe this group can help me. For example:
PERL REGULAR EXPRESSION RULE:
[[ c ]] (e|è|é|ê|i|î|y) -> s 

 we need to match the #"c" char and test  the next char to know if 
 we trap S phonem. example "Ce" must be emited S et E. I plan to have 
 2 rules rule: [ .../... "c" etc...  | "e"  etc... ]

More complicated rule:
an [[ c ]] T ->	
like for "banc"

CLASS V [aeiouàâéèêëîïôöùûü]			# voyelles
CLASS C [bcçdfghjklmnñpqrstvwxyz]		# consonnes
CLASS L (V|C)							# toutes les lettres
CLASS P [\,\.\;\:\!\?]					# ponctutions
CLASS N [0123456789]					# chiffres

CLASS W [_&\']+							# espace
CLASS S (^|W|P)							# limite gauche d'un mot
CLASS T ($|W|P)							# limite droite d'un mot

s: "Hello cè World" 
es: charset[#"e" #"è"#"è"#"ê"#"i"#"î" #"y"]

parse/all s [ to "c" p: skip es p2: ( p: change/part p "s" p2 ) :p 
]
? s

questions: 
-long string? then better copy instead of change/part
-more patterns in same path, then not 'to.

Volker that's not what I want to get ...

I'm seeking a rebol ruke that allow me to test the character after 
a key char example #"c" but keeping it into the parsing stack

you know p: and :p in parse-rules?

k I will try it thank u :)

yargh. I know how to split with a single character as the delimiter:

	chunks: parse/all text "^/"


How do I split where a blank line (2 newlines with nothing in between) 
is the delimiter? The naive solution I can think of just doesn't 
work:

	chunks: parse/all text "^/^/"

you can make up a rule.

lines: copy []
rule: [ copy txt to "^/^/" (append lines txt) skip 2 ]
parse mytext [ some rule ]

untested ...

I get lost trying to find a good way to describe my rule. Here's 
the bad code that states my intent, but doesn't work ('parse doesn't 
seem to like having that 'until in there)

chunks: parse/all text [
	until [
		chunk: copy ""
		copy chunk to "^/^/"
		skip
		if chunk [
			append chunks chunk
		]
	] 
]

ummm.. don't think you can do that

nope, I discovered that :-D

parse expects to see a parse dialect if you following it with a block

try my way ...

and your code is mixing rebol code with the parse dialect.

Rebol code has to be in ( ) when used within the dialect

oh okay. I understand that now.

that should be

parse/all mytext [ some rule ]

thanks

np

Hm. Still having issues:

>> rule: [ copy chunk to "^/^/" (append lines chunk) skip 2 ]
== [copy chunk to "^/^/" (append lines chunk) skip 2]
>> text: "Dude.^/^/Sweet!^/"
== "Dude.^/^/Sweet!^/"
>> lines: copy []
== []
>> parse/all text rule
** Script Error: Invalid argument:
** Near: parse/all text rule
>>

oh, wait.

oops .. should be "2 skip" and not "skip 2"

That's okay, I forgot to include the possibility that there would 
be only one line, so my tests were blowing up somewhere else.

Hm, that misses the last line if the text doesn't end in "^/^/"

easy enough .. add {^/^} to end of text before parsing

That *is* a nice and easy solution, thanks a lot!

sweet, all my tests pass now. Time to add more tests :-)

sometimes I find it easier to change the data than to change the 
rule :)

Hey, as long as it works.

Working on a textile parser over here to build my 'parse skills and 
make it easier to build my website with Rebol

not that you shouldn't do it, but I use http://www.rebol.it/~steel/retools/remark/

I'm <>-phobic ;-)

Remark takes care of all of those taggy things

and all of my pages are already in textile format, and I think a 
few of my friends would be more interested in Rebol if I had a textile 
parser for them

what's textile ?  A type of fabric ?

http://hobix.com/textile/

A structured text variant ...

yep

I like some of the different structured text formatting systems

Volker thank you it works great now and the code rule is tiny ;)

:)
