bad.el - ascii art games [package] [screenshots] [video]

[Emanuel Berg]

I have written a package, bad.el, that is something quite
spectacular. Unique - maybe - at least I didn't see anything
like that. It can already do interactive games and demos
with graphics.

It only uses one uncommon library, eieio. It doesn't use
gamegrid or anything like that.

Here is a demonstration video what it can do:

  https://dataswamp.org/~incal/bad/meta/bad.mkv

Here are a bunch of screenshots:

  https://dataswamp.org/~incal/bad/meta/cat.png
  https://dataswamp.org/~incal/bad/meta/egypt.png
  https://dataswamp.org/~incal/bad/meta/studio.png

How to get it:

  https://dataswamp.org/~incal/bad

  $ git clone https://dataswamp.org/~incal/bad.git

I'd like it to be added to GNU ELPA, which already has
`ascii-art-to-unicode' BTW. If that is okay, I will start
adding necessary docstrings and stuff.

Fun fact: There are at least 458 packages in GNU ELPA at
this point.

Well, did anyone try?

Thanks to user foxdie several bugs were found and hopefully
corrected, just do 'git pull' if you did the above.

A bunch of guys have tried this now and we discovered
a misconfiguration so the git command didn't work unless you
had a certain configuration, I had it so didn't notice - THAT
SAID, now it should for everyone, use the git command:

$ git clone https://dataswamp.org/~incal/bad.git

The git method is better, but you can also do 

  $ wget https://dataswamp.org/~incal/tmp/bad.zip

and then 'uzip bad.zip'.

You run the cloned/downloaded result with the 'so', 'eo',
'to', and 'po' scripts. The scripts must be executable, do
'chmod -x' if necessary. You can try to compile with 'co' and
especially 'no', that will make it much faster and smooth.

Note that if your 'emacs' refer to some old or defunct version
of 'emacs', you must rewrite the scripts manually so they will
run an as modern an Emacs as possible.

Other problems that arised during testing appeared to be
something out of nothing.

If nothing else, you can watch the movie bad.mkv in the
meta/ directory where there also are nice screenshots.

Remember, there are maybe life even on other *planets* :O

Could you plase ell us, in a few lines, _what_ this program does?
what sort of input does it use, and what sort of putput does it generate,
and how are they related to each other?

No problems at all, it is an OO(P) framework or development
kit for graphics. Right now, only ascii is supported but the
sky is the limit. Any game, application or other framework
that draws can benefit from using it. You can draw, you can
move, you can animate, you can play the game.

It uses eieio.el and that is what has made it all possible.
I wrote the framework and then no less than four interactive
very-small-but-still demos/applications in only 1 month and 1
day. One of these, the studio, is a drawing program and will
need many times the number of features, but it is there even
now, operation. The others are more or less done demos
demonstrating bad.el. eieio.el makes Elisp _a
pleasure_!

Yes, okay, in terms of Emacs one could say it is a combination
of `animate-birthday-present' (you wrote that), `gamegrid' and
`artist-mode'.

But it still isn't that because when you draw, you can rotate,
flip, transpose, change size, move, and whatever you can think
of. Because it is all objects with methods, just add a new
method for every idea. And after you draw a thing, you can
draw something else, a hundred other things, and then return
to the first and start over, because it is still live.

Here are a web page (that now works) with a bunch of
screenshots as well as how to get it. The text isn't
important, just look at the screenshots for now. There is
a video, but I realize now I should have done it longer,
more clear.

And how can a drawing program be all that at once?

It is because you don't just draw what things are - "they are
like this" (the bitmap/raster way) - or "they are like this as
some data system, devised to express them, to save disk space
and be zoomable" (the vector way) - no, this way is different
because what is also included is _how they behave_.

After you draw (even while you draw), they are not dead, so
you can shout: BE ALIVE! and then you have an animation.
or shout BE AT WAR! and you have game. Or BE NORMAL! and it is
a simulation.

Okay, I'll do a new video! Huge mistake by me, this, not
taking it really slow showing and explaining. The video will
show everything, God willing. But I am now not at the level
when I wrote all that code, so be patient as I know you are
and it will come - I don't know when it will come.

Re: bad.el - ascii art games [package] [screenshots] [video]

Here is another example. It is called "The graphic Object
Editor" and is described as "Interactive edition of
hierarchical properties of graphic objects".

https://help.scilab.org/docs/2024.1.0/en_US/object_editor.html

It starts

  [It] provide[s] graphic editing operations for the different
  kind of graphics objects (see graphics entities for more
  details), including the enabling them, disabling them, and
  editing their properties, before or after they have
  been drawn.

  Internally, each graphic window, and the drawing it
  contains, are represented by a hierarchy of entities.
  The hierarchy top level is the Figure. Each Figure defines
  at least one child of type Axes. [...]

The details are not cut in stone but they speak of exactly the
same editor type and model to deal with graphics in a way that
is - very good. Infinitely more powerful and maybe we can even
reinvent the thing by combining with the input interface of
`artist mode'. Self-documenting, self-balancing...

Yes, hierarchy! I even showed you the pyramid I had, with
boxes in boxes in boxes.

It sounds interesting, and leads me to a few more questions.

* Does it define its own system for classes and methods?
If not, what does it use for that?

* What non-basic facilities of Emacs does it depend on?

* Is its display done using characters, like `animate-birthday-present',
or can it be draw in terms of pixels?

* does every kind of visual object _have to_ have is own data type?

Not sure what you mean, it has its own system which begins at
the `elem' (element) base class, but the OO part is provided
by eieio.el as mentioned.

> * What non-basic facilities of Emacs does it depend on?

My own, and

(require 'cl-lib)
(require 'eieio)
(require 'subr-x)

Chars, but pixels is the next step, I would like to do that!

No, you can draw or type any way you want, as long as you don't
tell the program to overwrite it. You can also draw manually,
if you will, via the program, by manipulating a "data" member
and then let the program draw it.

Well, it doesn't have to be. Let me take that back and just
answer the question. No, it only does chars, and no pixels.

30 000 pixels in 3.76 seconds, Python Pygame SDL2 C version
from Elisp.

We need a much better frontend and backend tho, possibly
backends for other libraries if people prefer them - those
will be up to them to write, of course.

This screenshot - the same application, bad.el, running the
same Elisp, on the same Emacs.

left  - executes from Emacs, and is also drawn by Emacs, Elisp and bad.el;
right - executes from Emacs _but_ is drawn by SDL2.

And so the fun and innocent ASCII art have or can become
C-compiled SDL.

I'll be damned, oh gosh.

"This I didn't see coming!"

But, I'm running out of steam :(

In the last Emacs NEWS letter there were 120 posts. On #emacs
there are 800 people. Maybe 10 people talk.

Maybe instead of writing all those blog posts and hours spent
lurking, someone can come to my aid just a little bit?

We just need a simple Elisp frontend and ditto Python backend,
or if you want to implement some other library that you prefer.
