[REBOL] Parse, spaces and ()s
From: davidv:angliaed at: 31-Aug-2000 11:27
Newby question...
Can anyone tell me what is going on here? The following output is produced by
the script below
one
(
two three
)
four
(
five
(
six seven
)
eight
)
Why do "two" and "three" appear as one string (same with "six" and "seven")
and not split up at the space between them like everything else is - obviously
the () have something to do with this - but I can't find an explanation
anywhere. Also, what mods would I need to make to force it to split these
particular strings at the whitespace?
REBOL []
blk: []
brkt-chars: charset ["()"]
brkt: [some brkt-chars]
word-chars: charset [#"a" - #"z" #"A" - #"Z" #"0" - #"9"]
word: [some word-chars]
word-def: [word]
brkt-def: [brkt]
get-word: [copy value word-def (insert tail blk trim value)]
get-brkt: [copy value brkt-def (insert tail blk trim value)]
rule-block: [get-word | get-brkt | skip]
str: "one (two three) four (five (six seven) eight)"
parse str [some rule-block]
foreach item blk [print item]
Thanks in anticipation (I've only been playing with REBOL for about a week so
forgive my ignorance if this should really be obvious).
David
