TNoodle in python

[cubetastic33]

I want to use TNoodle in python. Is there any python version I could use? otherwise, is there any way to use the other code in python? Thanks!

[jfly]

@cubetastic33, TNoodle is written in Java, so it's not possible to run it in plain python. However, it is possible to use TNoodle through Jython! You can see us doing that in our .jy tests: https://github.com/thewca/tnoodle/tree/master/scrambles/test.

[cubetastic33]

@jfly cool! But, where are these imports from?

import tntdebug

from puzzle import TwoByTwoCubePuzzle from puzzle import NoInspectionThreeByThreeCubePuzzle from net.gnehzr.tnoodle.scrambles import AlgorithmBuilder

How do I install those modules (if required)?

[jfly]

tntdebug is here: https://github.com/thewca/tnoodle/blob/master/tntdebug.py

The other stuff is written in java. Jython let's you import java code, which is why this all works. You can find some more information about how exactly we invoke jython in this script: https://github.com/thewca/tnoodle/blob/master/jython.

[cubetastic33]

@jfly ok, but how do I execute this code? Like from my terminal? If I try jython filename, it obviously didn't work

[jfly]

Yes, from your terminal. If you have trouble with that, I suggest looking at what Travis does to run the tests (see https://github.com/thewca/tnoodle/blob/4f8781e40f005b5dc8cc79cb99dd6991d12b2ca0/.travis.yml#L25).

[cubetastic33]

@jfly I still don't understand. What command should I use?

[campos20]

Out of curiosity, what are you trying to do? I mean, generate scrambles? Are you writing a stand alone software?

[cubetastic33]

@campos20 well, I am trying to generate scrambles on my Raspberry Pi 0 W, and show them on an lcd screen.

[cubetastic33]

@jfly when I execute the command ./tmt make check, it is giving a lot of logs, but how do I generate scrambles from a different python file? like, what function do I use?

[jfly]

@cubetastic33, I'd suggest reading our tests, it should be fairly obvious what's going on. Try taking a look at https://github.com/thewca/tnoodle/blob/master/scrambles/test/NoInspectionThreeByThreeTest.jy#L62.

@jfly When I finished running it, this is what it said:

[jfly]

What's the "it" that you ran? Is that the entire output?

[cubetastic33]

@jfly I ran ./tmt make checkagain, and I got the following result:
