best practice: programming language & sage interaction

[Michael Wagner]

Dear All,

What is the recommended way to use SageMath in for example Scala? 

At the moment I am using a python tcp socket, which I am running via the "sage -python name.py" command. It receives functions, casts them and calls "simplify_full()" on them.

(Context: the goal is a program, which can find relations between the generating functions of the sequences in the OEIS.)

In kind regards, 

Michael

Given that SageMath is just a Python library (the only Python
implementation supported is usual one, CPython, though), anything that
works for (C)Python should work for you.

Dear Michael,

The SageMath software has a long startup time. "sage -python name.py" is
likely to be too slow. I would suggest that you use it in a more
interactive fashion. As Dima said, anything that works with CPython
will work here.

Though, if your goal is to find relations between the OEIS sequences
I would rather
* use Python directly (then Sage will be available)
* or write all in Scala (and ignore Sage)

Best
