Tetris: ATS+Bacon.js

gmhwxi · May 2, 2015, 10:39pm

Here is an implementation of Tetris in ATS+Bacon.js:

The graphics for the game uses easel.js by createjs.

There is clearly a lot of room for improvement. Part of my purpose for
writing the game was to test atscc2js, the compiler for translating into
JavaScript the C output from ATS source. I myself find ATS+JavaScript
co-programming to be very interesting.

If you want to play with it:

Please help improve it (and have fun!).

Emscripten is far more general than necessary for compiling the C code
generated from ATS source.

If I have an implementation already written in C and want to translate it
into JS,
then using Emscripten makes sense. If I want to implement something to run
in
browsers, then doing ATS+JS co-programming (with atscc2js) makes more sense.On Wednesday, May 6, 2015 at 4:50:35 PM UTC-4, Yannick Duchêne wrote:

My personal theoretical opinion is: the path which goes from ATS to
JavaScript, may be safer, as it requires less assumptions and as Emscripten
has a lot of dependencies, which to me means more opportunities for an
error somewhere.

Now, I don’t know if this theoretical opinion is confirmed in practice.

This thread may be the opportunity for a basic question: what’s the
recommended path to get a working atscc2js?

I installed ATS/Postiats 0.1.11, compiled astcc2js with it, but running
patsopt -d test.dats | atscc2js -o test_dats.js I either get an error
about a missing (not available for staloading) STATS/option.sats if I use
the libatscc2js from contrib from SourceForge or syntax errors (“the
syntactic entity [xyz] is needed”) if I use the libatscc2js from contrib
from GitHub.

I wanted to test if ATS typing can help me with maintenance issues I have
with some JavaScript.Le dimanche 3 mai 2015 00:39:14 UTC+2, gmhwxi a écrit :

One more thing:

I forgot to mention that atscc2js makes it very convenient to mix ATS code
with JS code.On Sunday, May 3, 2015 at 10:03:00 PM UTC-4, gmhwxi wrote:

We tried both:

ATS → C -(atscc2js)-> JS

ATS → C -(emscripten)-> JS

Actually, Will Blair first tried (2).

Right now, (2) is clearly much more powerful as it essentially has the
full library support of ATS.

I use (1) mostly for the teaching purpose. Also, I use (1) because I can
gradually build library support
not only for atscc2js but also for atscc2py, atscc2php, atscc2pl, etc.
Maybe for atscc2erl in the future

I did this, just installed git before (may be added to the script, as it’s
not installed as a default), added --prefix=/home/<directory> as an
option to configure on line 42, executed the script, executed make install, then moved
ATS2-contrib/projects/MEDIUM/CATS-parsemit/JavaScript/atscc2js to
<directory>/lib/ats2-postiats-0.1.11/bin, added a script similar to that
for patscc, but for atscc2js in <directory>/bin.

Now it’s fine, the test files compiles, as well the Tetris game.

Thanks to you and your students, I may have a Tetris time tonight .

I will stick to this procedure for future re-install or updates.Le samedi 9 mai 2015 20:13:53 UTC+2, gmhwxi a écrit :

patsopt -d test.dats | atscc2js -o test_dats.js I either get an error
about a missing (not available for staloading) STATS/option.sats if I use
the libatscc2js from contrib from SourceForge or syntax errors (“the
syntactic entity [xyz] is needed”) if I use the libatscc2js from contrib
from GitHub.

I wanted to test if ATS typing can help me with maintenance issues I have
with some JavaScript.

Here is an implementation of Tetris in ATS+Bacon.js:

https://github.com/githwxi/ATS-Postiats-contrib/tree/master/projects/SMALL/JSmygame/Tetris

The graphics for the game uses easel.js by createjs.

There is clearly a lot of room for improvement. Part of my purpose for
writing the game was to test atscc2js, the compiler for translating into
JavaScript the C output from ATS source. I myself find ATS+JavaScript
co-programming to be very interesting.

If you want to play with it:

Index of /COMPILED/doc/PROJECT/SMALL/JSmygame/Tetris

Please help improve it (and have fun!).

Cheers!
