[REBOL] Re: Another question

Hi Alex,
<< The point is, these escaped quotes should not be treated as grouping
constructs, but as normal text. So this:
\"Hello world,\" I said
should result in [{\"Hello} {world,\"} {I} {Said}]. >>
OK, forgive me if I go off-track as I'm trying to understand what you
actually want to accomplish. Do you want the escaped chars to remain
unchanged, still as escaped chars, or do you want them to be translated into
a more normal REBOL form (i.e. unescaped :)? Using the /all refinement with
parse, and specifying only a space for the rule, will give you the former.
>> parse/all {\"Hello world,\" I said} " "
== [{\"Hello} {world,\"} "I" "said"]
>> parse/all {\"Hello world,\" "I said"} " "
== [{\"Hello} {world,\"} "I said"]
<< I'm trying to find "[" + "red" or "blue" or "green" + "]"
within a string, *find* it, not just see if a string matches it. >>
Sorry, I'm still confused. You can use FIND to find it but my previous
example, using block parsing, returns what it found as well.
>> find "this is my [red] car" "[red]"
== "[red] car"
>> parse [this is my [red] car] [some word! set b block! to end]
== true
>> b
== [red]
Parse, in this case, finds the block for you and sets the word B to the
block it found.
Am I getting warmer?
