Hello Anton, Joe,
I wasn't the initiator of this request, but it directly relates to a
concern
of mine.
Though I can live with just at-xy and and scarce polices, the lack of
graphics words in Gforth, and the reluctance to provide them in
general in
Forth, has something extremely bizarre that I concluded is a part of
an
"elite" club wanting to remain tiny.
Not at all, more a reflection that this topic has a bewildering
multitude of incompatible and aften complex APIs in the world outside
Forth, so what should our (one) graphics API target?
By contrast, text I/O has pretty much one API on the C level, even
though what's behind that can be quite diverse (display on a serial
terminal, the console, a local terminal emulator window (with lots of
terminal emulators available), through ssh on a remote terminal
emulator, on a local terminal emulator with a display on a remote X
server, an emacs terminal buffer, etc.), so it's relatively easy to
support.
Anton, in your answer to Joe, I can hardly figure what "open a pipe"
means
in reality for me,
https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/Pipes.html
And I just rediscovered an example of how to use that for graphics:
http://www.complang.tuwien.ac.at/forth/programs/ps-example.fs
or "through the C interface" etc.
For Gfoth 0.7:
https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/C-Interface.html
It's slightly different in the current development version:
https://gforth.org/manual/C-Interface.html
Then you look at the C graphics API you want to use, and call the C
functions through the C interface.
Reading this I imagined that if only there is a single (Forth) word,
for a
given OS ok, to draw a pixel where I need it with graphic attributes,
That
would be cataclysmic in the Forth world. Like:
: Pix. ( RGB i j --)
????????
;
Then many would be in heaven.
When I posted about ps-example.fs in 2010, there was not much
reaction; maybe once you are in heaven, there is no desire to post.:-)
