Is this a native Forth project?

It appears to be. I'm unable to build it on my Mac, but the makefile
creates a disk image for qemu.

This issue is not related to Forth it self. It will be better to
contact me on sourceforge for this.
I put a pre-compiled image for you. Use it as the first hard drive in
qemu.

No one needs another small, low-level Forth.
What is needed is a high-level Forth that is designed
for desktop applications, not for flushing toilets.

So write one already if you are so perfect.

Who knows weather it can be of use for someone ?

I'm working on a forth system for application purposes but it will not
assure to you because it is a functional color forth dialect with some
auto parallelization support inside. It will be used mainly as
application language for processing 3D data.

And you'll be releasing your all-singing-all-dancing GUId up
SexyForthYeahISoRock V1.0 when, exactly?
We're all just dying to see it.
Bernd Paysan
No one needs another big Forth with GUI and everything, since that also
already has been done ;-).

congratulations Jean-Francois, for know forth, nothing better that
making one !
see ColorForth for make more simple and agry more people :)
good luck,

My next step is to write the tools I need to build a 32 bit protected
mode Forth. From there, and maby in the same time, I do the "high-
level" stuff.
ie.: In the file src/VGA.fth I have a primitive window component. It
give a better look to my block editor ;-p

Don't VFX Forth and SwiftForth work for that?
Looking around in advance of the arrival of my dirt cheap $120 Chinese
Netbook, if they were x86 processor machines, I'd be sitting pretty.
I'd say what is needed is a high-level Forth that is designed for
writing specialized Netbook / Webtablet / PMP applications, since I
don't see similar to VFX or SwiftForth available for ARM or MIPS
processors - either build gForth up to that or build ARM and MIPS
kernels with wordsets that can load and run the VFX or SwiftForth
application support libraries. And of course buying a solid desktop
Forth to get the application support libraries is no bad deal, either.
Jean-Francois Couture
thank you Pablo. It is true I learn a lot writing this. And still have
lot to learn. Like english...
What I realy like from Forth is its standalone nature. With real-forth
I can use my PC without any OS doing things I dont ask for.
I download colorForth but I dont figure out how to use it wet. ( I
only try 2 min. )

It must include:
a garbage-collector
lists
hash-tables
a regular-expression engine
Jean-Francois Couture
You should try Java...you gonna get all this and you not have to worry
about the hardware.

No, I'm looking more for what you get when you compile gForth in an
ARM based Linux, except with more extensive support libraries. Host-pc
applications, just with a slightly smaller (though hefty RAM / mass
storage by 10 years ago standards) host-pc.
The capabilities of VFX and SwiftForth are likely massive overkill for
what I'd be doing, but I have no doubt they'd be ample.

ok, some interesting info is growing from Ray Stm.
look in

for an interesting info about internal colorforth

I have another (yes another!!) forth, but using ideas from colorforth.

there are a lot of nice people in this forum ready for help, just

Add the existing garbage collector to the existing Gforth package and
you are done.

When your highest goal is to control the flushing of a toilet,
Forth shines. Operating system? We don't need no stinkin'
operating system! Forth was destined to manage turds!
This isn't a newsgroup devoted to embedded controllers.
If you want that kind of group, get out and stay out.

Hi Jean-Francois,
Merci bien pour votre nouveau Forth.
Please ignore anyone who says you are not welcome on clf ;)

This isn't a newsgroup for telling people how to behave. If you want
that kind of group, you had best look elsewhere.

There is a nice search engine called Google:
http://www.google.com/search?q=colorforth
E.g. 7th link looks interesting, if you really want to use ColorForth,
which is not recommended for beginners.

Possibly you can take a look at the native port of Retroforth 9
http://retroforth.com/download/9.0/
The sources are multiboot conform (you can boot it from grub for
example).
Another, plain simple boot enviroment for x86-64 systems:
http://www.returninfinity.com/baremetal.html
ColibriOS (alias MenuetOS 32) is an OS written completely in assembly.
The sources can be an inspiration for driver code, multiprocessing
etc.

Interesting. I had no idea gforth had a regex engine.
Does it actually have general-purpose hash tables, or do you have to
hack around with wordlists/tables?

TABLEs are general-purpose hash tables, wordlists are case-insensitive
for ASCII. The key length in either case is 1/8 of the address space,
so it's general-purpose as far as I am concerned. What would you miss?

What if I want to store arbitrary data values in a hash? It seems to me
that the result of a lookup is always a name token. I can obviously
work around this with CREATE..DOES> and a wrapper around find-name to
immediately execute the word, but that seems a bit overkill...

If you use FIND-NAME for the lookup. With SEARCH-WORDLIST you get an
execution token.
>I can obviously
>work around this with CREATE..DOES> and a wrapper around find-name to

The EXECUTE or >BODY (and NAME>, if you use FIND-NAME) is relatively
cheap compared to the rest of the lookup. BTW, you only need CREATE
(no DOES>) if you only want the address.
What might be a little more of a concern is the space overhead: You
have the length (1 cell), padding, link field, and code field; for a
special-purpose hash table you may not need any of that; for a
general-purpose hash table, you do not need the link field and the
code field. Still, I wonder if the hash tables in other languages
that have them are any more efficient. Maybe I'll measure this one
day.
