#44954 — RedaForth

Does anybody know where to find RedaForth?
It includes an impressive vector graphics editor, as seen at https://www.youtube.com/watch?v=ZX8GBpIz5b0

Today I accidentally found these lines:

Recently, a new open source Forth has been released the public domain. It is
been used to teach children from poor areas, the fundamentals of
programming. The system is tiny - the full distribution is a just 386kb zip
file

    http://www.geocities.com/redaforth/reda4pc.zip

I was mostly impressed by the vector graphics editor that it includes (image
attached). It is used by the kids to draw their cartoon characters, but also
to define the fonts used by the system.

Cheers,
Francisco

1. Geocities has been gone for a while and that link redirects to
some random business page.

2. 386kb zip file sounds like a relic of the DOS era, not likely to get
much traction for educational programming nowadays.

For a simple Forth system that's plenty.  IIRC redaforth is from Ron
Aaron, who posts here regularly (more about 8th in the last year or
so), and was still dicsussed a few years ago, so no, it's no relic
of the DOS era.

Heh.  No, my old Forth was Reva Forth and it is still being used though
I'm not maintaining it any longer.

I guess that redaforth is from Pablo Reda.

The Wayback Machine is up today:
Useful links (in SPANISH) appear to be

and

The later has links to downloads. I could not verify integrity of

Thanks, Pablo!

I used the Download ZIP at https://github.com/phreda4/r4MV and unpacked it, but I didn't know what to do with it.

Is there a Readme file or are there some instructions somewhere to get it running? Wich OS is supported?

Thanks a lot in advance,

Dirk.

Dirk,

r4vm is the virtual machine, not the system.

download https://github.com/phreda4/reda4

unzip in a folder and run.

Thanks, Pablo,
I got it running. A colorless ColorForth, as your README.md tells me - but the editor shows colors instead of prefixes.

I like to know how it works, so I started to translate resumen-manual.txt using Babelfish and Google-Translate. Babelfish allows only a few lines, but the translation is better. Here the first part:
-----------------------------------------------------------------------------
The best is that it is not necessary to read... 

User's Manual: r4 
Another language... to increase the general confusion. 

Features 
	Brief language 
	No syntax rules 
	Rapid development 
	Cross-platform

Change encoding rules 
	There are no local variables 
	There are no explicit parameters 
	There are no calls or jumps 
	It is important to rebuild rather than patch 
	Short definitions

It changes rules of analysis of the problem 
	Components are sought. 
	Vocabulary is built. 
	Expressed the solution to the problem. 

Description 
	Postfix (2 3 + instead of 2 + 3) 
	Stack of integer data 
	The code is a dictionary 
	Words separated by space 

The code is in the file .TXT in the distribution. 
The sequence of words contained in these files are called 
CODE 

The code divides sequence of characters separated by spaces called 
WORDS

* When the word is a number, it stacks on a stack called DATA STACK 

In addition to numbers: r4 defines prefixes to indicate the function of each word, these are: 

	^ include 
	| comment 
 	" chain 
	: action 
	# data 
	' address 
	$ hex number 
	% binary number

so: r4 can find decimal, hexadecimal, and binary numbers

455 $ffff %10101011 | <-- Valid numbers that are stacked
-----------------------------------------------------------------------------

I looked at some files of your reda4-master and I see it is a lot of work and the resulting r4.exe looks nice. But I learned today, what somebody else wrote long ago: "If you know one Forth, you know one Forth"

I would like to learn about the graphic features of your Reda-Forth, but I don't see a way to get there.

But then I discovered your manual, translated to English: manual-eng.txt

Quote:
"End of 2005, the need for an alternative to the problematic C language, with its incoherent accepted practices (don't use global variables) and its goal of producing optimized code (use global variables), lead the author to the study of Forth.
...
:R4 is a language inspired by ColorForth, with a basic growable dictionary of 109 words, a data stack, a return stack and 6 prefixes with different functions.

This manual is the first documentation for the language. You will find here a description of how it works, the behaviour of each word, some examples and a quick reference to the language.
...
As someone said, simplicity is the final goal, not the starting point."

At the end there is an explanation, "How does :R4 run ?", worth to try it.

I would like to try the "Bouncing Ball", but I didn't find out how to start.
Any hints?

Look carrefully, the editor show prefixes with colors

Ok, the manual is a bit outdated,
better try and see code in the zip
r4 start in a graphics windows, not console exist
the exe take main.txt (code) ans run the browser program.
this browser look r4 folder, if you modify something here the browser show the changes..
then F1 run, f2 edit f3 new (you need enter a name)
in the ide (f2) you edit the code

this is the same example working
---------------------------------------------
^r4/lib/gui.txt

#ball
 $19A1231 $873A1232 $87380444 $8739F662 $199F664 $7BFDF662 $7BFC0444 $7BFE1232 $19A1239 $11A3B0F7 $C6D49C08 $FFFFFFC $FF0000F 0

#xb 0 #yb 0 #vx 8 #vy 0 #ay 2

:toc		vx neg 'vx ! ;
:tic		vy neg 'vy ! ;
:drawball	100 100 dim xb yb pos 'ball nsprite ;
:screen
	show cls
    	drawball
		xb vx + 
		sw >? ( toc ) 
		0 <? ( toc ) 
		'xb !

		ay 'vy +!

		yb vy +
		sh >? ( tic drop sh )
		'yb !
		'exit >esc<	;

: screen ;
---------------------------------------
you can copy&paste this example in a text file in the r4 folder and then run with the browser.

I think this is the one you are looking for (but in its latest incarnation)

https://code.google.com/p/reda4/

which is now:

https://github.com/phreda4/reda4

keep in mind both are for wine and android.
