dartpy 0.0.1

A starting point for Dart libraries or applications.

An dart-ffi library allowing calls to Python®

Usage

A simple usage example:

Darpy is a library that allows dart to call out to python code /// For a simple python script inline you can do the following:

void main(List<String> args) {
 dartpyc.Py_Initialize();
 final python = '''
 from time import time, ctime
 print("Today is", ctime(time()))
 ''';
 final pystring = python.toNativeUtf8();
 dartpyc.PyRun_SimpleString(pystring.cast<Int8>());
 malloc.free(pystring);
 print(dartpyc.Py_FinalizeEx());
}

For a more complex script that you don't want inline you can do this:

void main() {
  // initializes the python runtime
  pyStart();
  try {
    // imports a python module
    final pyModule = pyimport('multiply');
    // gets a function within that module
    final pFunc = pyModule.getFunction('multiply');
    // calls the function and gets the result
    final result = pFunc([1, 2]);
    print(result); // Should print 3
  } on DartPyException catch (e) {
    print(e);
    // Cleans up memory
    pyCleanup();
    exit(1);
  }
  // Cleans up memory
  pyCleanup();
  exit(0);
}
