[REBOL] parsing..
From: eric::ehrichweiss::com at: 8-Jan-2005 16:04
I'm an old school Amiga programmer(which probably means I'm among many
old friends) and was especially fond of Arexx. Well that thought brought
me to this post...
The parse command seems to need improvement unless I'm not understanding
it and I think that a great place to start might be by looking at what
Arexx does. For example. I have several projects that require a single
input line to be parsed into several variables. If I'm understanding
Rebol's parse command, it can only do one variable at a time, Arexx did
them until you were satisfied...so instead of multiple or recursive
parse commands you could do "parse input "abc" variable1 "def" variable2
ghi
variable3 "jkl" " It's as simple as that for the most part. You
can vary how the delimiters work with wildcard functions like "abc#?def"
which means that there are some characters between 'c' and 'd' that are
unknown in length. It's been a while since I used Arexx so forgive me if
my syntax is off a bit.
Anyway, if this is possible with a single line, please show me an
example since the one on the language dictionary seems very limited. And
if it isn't possible currently, what would be necessary to make it possible?
Eric
