polydojo / jispy Goto Github PK

I'm trying to run unicode JavaScript source and it fails :(

Would you please add the __init__.py to use jispy as Python module?
Or even wrap it for pip install jispy?

Looking to include this work into another project but you do not have any releases or tags. This would mean adding a commit into the requirements.txt file which is not a big deal but is undesirable.

Is there any reason for not have a release? To be honest it is a negative of the project as it implies it is not ready for use.

This code shows the problem with the jispy interpreter:

var makeClosure = function (x) { var func = function (n) {return x+n;}; return func;},
myadderone = null,
myadderthousand = null;
myadderone = makeClosure(1);
myadderthousand = makeClosure(1000);
print(myadderone(0.5));
print(myadderthousand(1));
print(myadderthousand(2));

It evals to 1.5, 2 and 3, whereas it should be 1.5, 1001 and 1002.

The problem is that the inner function gets x=1 during the assignment
myadderone = makeClosure(1);,
which is a correct behavior, but then x=1 value remains when
myadderthousand = makeClosure(1000);
is executed, which is wrong.
Somehow crEnv in Function Object does not get created anew and that first environment with x=1 becomes forever attached to the inner function func.

Is it Safe to use this to run arbitrary code? I was thinking about using this in a filtering engine that users could right functions to filter objects. Is it safe?
