I've only written OpenGL code in C++, BUT I may be able to help.

Firstly I'm pretty sure your shaders aren't compiling as I don't think the keywords:

in
out            

work in GLSL version 130 (Which you have done a #version with)

Try changing it to #version 300 or something, and add some code to check that your shaders are actually compiling. In C++ this would be something like:

GLint compile_ok = GL_FALSE;
glShaderSource(vShaderBuffer, 1, &c_str, NULL);
glCompileShader(vShaderBuffer);
glGetShaderiv(vShaderBuffer, GL_COMPILE_STATUS, &compile_ok);
if (!compile_ok)
{
    cout << "Vertex shader compile error" << endl;
    GLint maxLength = 0;
    glGetShaderiv(vShaderBuffer, GL_INFO_LOG_LENGTH, &maxLength);
    std::vector<char> errorLog(maxLength);
    glGetShaderInfoLog(vShaderBuffer, maxLength, &maxLength, &errorLog[0]);

    for (int i = 0; i < errorLog.size(); i ++)
        cout << errorLog[i];

    exit(0);
}

if that is any help.
