1. REBOL-lion
Has anyone played with the REBOL language recently? Can anyone do the following
in Euphoria (without 'include'ing anything)?
REBOL [
Title: "Fetch the Cyclone watch report for Indian Ocean"
Date: 24-Apr-1999
File: %cyclone.r
Purpose: {
Fetch an HTML doc from the net and save it as a file.
uses parse to pull out only that text as needed.
}
]
outputFile: to-file "..\temp\cyclone.txt"
if error? try [ blk: read http://www.wunderground.com/tropical/ABIO10.html ] [
save outputFile form reduce [ "No report for" now/date ]
quit
]
parse blk [ thru "<pre>" copy text to "</pre>" to end ]
if error? try [ save outputFile text ] [
save outputFile form reduce [ "No report for" now/date ]
]
quit

Such questions are intriguing in one sense, but they are also somewhat
misleading. For example, can REBOL transpose a matrix in one statement?
Well, apl could. Does that mean that apl is better than rebol? Yes and
no. Each language has certain purposes and strengths. Comparing two
languages on one snippet of programming is therefore like asking which is
better: oranges or grapes? Which should we be eating? The answer is that
both have their purposes.
If one language was perfect, there would only BE one language...
I'll bet there are lots of really nice features in Rebol. But I'll also be
that there are some things that it can't do well. Just like Euphoria...
Cheers!

I noticed it some time back. I thought the language looked interesting, and
the web pages were well laid out.
The 'read' looked pretty cool, and would be a nice addition to Euphoria.

Funny you should mention that, I just picked up learning it again after a
few
months. The program you wanted to translate to Euphoria looks simple, but
underneath it's very complex (the language hides the complexity from
you).
REBOL is an "Internet messaging language". It has built-in support for
TCP/IP networking, plus most major application layer protocols, like
HTTP,
NNTP, SMTP, POP, FTP, etc. It also has support for parsing MIME messages
and HTML documents, since they go along with the protocols :)
Unfortunately, Euphoria doesn't currently support those protocols without
alot of wrapped up Win32 DLLs. It's amazing how much actually happens
when
you do 'save %eu.html read http://www.rapideuphoria.com/' :) One of the
things I love about Euphoria is the ability to handle alot of low-level
things like disk i/o and memory allocation. REBOL was designed to shield
these kinds of things from the programmer, so they can write their
(Internet)
application as quickly and simply as possible.
A trap some people get into is trying to use one language for everything.
Like
someone else said, if you could do everything with one language, there
would
only _be_one_language_. So, being the lazy programmer I am, I would just
stick
with the REBOL code :)
