Re: [colorforth] About a byte-sized colorforth

Thanks for your input!

I was thinking of a token oriented editor. I wrote a display routine 
that display evey token sequentially
with a predefined color. Its all written in assembly. The cursor would 
highlight whole tokens (words).
When a change must be made, a special token input subroutine kicks in. 
e.g.  for bincopy, it only accepts
0...F characters and an even number of them.

I want  to keep isomorphism, here's an example of what I'm thinking now;
To handle literals, I could use a macro called "#" that would:
1- call the ?dup macro, defined previously in source
2- Save the current address for subsequent ?lit (see colorforth source, 
search for list and list+4)
  For this I use "mov edx, ebx | mov ebx, edi"
3- Compile the correct opcode, b8h  "mov EAX, imm32"
Each lit could be written as a binary token prefixed with this # word.
#78563412, with correct colors, would mean a litteral.

And ?lit becomes ?#. (123, !@#, store fetch lit... ;o)
Theres many scheme but this one would be the most elegant, because of its
simplicity and the fact that WYSIWYG. But a higher level editor could be 
made,
giving litterals a new color, etc. But isomorphism get the boot, it 
brings complexity in.

I don't understand your suggestions about definitions going inside indices.
I know 128 definitions isn't much, but its enough for most program
I came to think about.  I thought about the difficulty to link program 
blocks
between themselves with let say a LOAD word. I have not resolved it yet,
maybe because its a non-problem, since the editor could enable you to easy
copy tokens between blocks.
