1. Congrats, David!
Heh? Does this list still work?? I haven't received
any messages since yesterday.... weird...
Anyways, Congrats to David Cunny for his OX parser
generator! It saves a ton of work when wanting to
implement language parsers, INI file readers, or Text
To Speech in Euphoria!
Euphoria was lacking a parser generator...
C has tons of 'em, YACC, BISON, FLEX, etc..
For all yall that don't know how a parser generator
works...
If you want to, for example, implement a programming
language in Euphoria, then you would normally write
code to read a source file, break it up into little
tokens, wich you then eighter run or translate to
another language. Coding this is very boring work, but
with a parser generator you just tell a program how
your language looks like, and it will output a program
that can read a file in that language you specified,
break it up into tokens, and prompt you with a token
when one is encountered, so you can immediatly
translate or run it, or store it away in memory.
Pretty cool shit.
If you compare writing a programming language from
scratch, or writing one using OX, OX saves you 70% of
coding time.

Sounds familiar.

I don't really like pre-announcing stuff, but since you also brought up Java
the other day, I'll mention that work is progressing well on my Java to
Euphoria translator.
The translator is a complete rewrite of my Java to Euphoria translator,
borrowing heavily from what Robert has done with EC.
Much of the 'core' grammar has been coded, and enough library routines have
been written for it to translate simple, non-interactive demos such as Buzz,
Queens, Sieve after minor modifications.

D'oh!
And I even changed it around after I had written it, thinking I was
correcting it.

I thought it was a Euphoria to Java translator? no?

Robert, why didn't you write E2C in Euphoria? It seems Euphoria is totally
capable of doing this job. Are you affraid it would be too slow? Which
language was it?

I'm sorry I misspelled your name, David :)
Won't happen again! ;)
I downloaded the latest version of Euphoria To Java
yesterday, and must say that I'm impressed.
This is an excellent tool, that could go commercial if
you wanted to.
But there are two things that can be done better.
For one, use the Vector type in Java to emulate
sequences, in my oppinion they are much faster.
And two, Java is very popular because most Web
Browsers can run Java applets. Therefore, why not add
some browser-specific built-in routines to the
Euphoria syntax wich can be used by Eu coders to
create Java applets easier for their web pages. That
way, Euphoria can be used virtually to create web
pages.
But if you can code a Euphoria to Java translator (and
proved you can), then why not try to write a Euphoria
to C or C++ translator? Java syntax is almost
identical to Cn just with a few obfuscating
improvemnts here and there. That way, you can write a
Euphoria to C translator wich uses your own built-in
routines wich might be faster than RDS', plus, you can
support any compiler and target platform (like
Consoles) you want if you output C code only without
precompiled libraries, and add some #ifdef's to
platform-specific code. With your excellent OX parser
generator, and your programming skills and experiance,
you could do this very easily.
In my oppinion, you are the best Euphoria programmer
ever, Pete Eberlein coming second, and Mic third.
If you'd do something similiar, I'd be happy to write
run-time Euphoria library routines for all platforms
for you. And I'm sure others would contribute aswell.
Because you allready have the skills to translate to
Java, wich in my oppinion is even harder to do than
when translating to C, I think you should go for it.
Even a small translator would be cool, so others like
me could hack away on it and add features.
A Euphoria to C translator written in Euphoria is
realy what a lot of us would want to see...

The Translator shares the same "front-end"
(scanner, parser etc., written in C) as the interpreter.
This allows me to re-use existing code
and maintain maximum compatibility
between the interpreter and the translator.
If you've run the Translator, you'll know that it only
takes a few seconds to translate a large Euphoria
program into C. Your C compiler will likely take
longer just to compile one of the many .c files that are
produced. If the Translator had been written in Euphoria,
the speed would have been acceptable, even using
the Euphoria interpreter to run it, but of course you
would translate the Translator into C and get something
very close in speed to one done in hand-written C.
As an isolated, stand-alone project, done from scratch,
I would definitely have done it in Euphoria. Coding in
Euphoria saves you a lot of time and headaches
compared to C.
