PyGObject

PyGObject is an open source and totally free library software written in Python and designed for developers who want a collection of Python bindings for the GLib Object System (GObject) and the GLib library, to be used in the Python programming language. The main goal of the PyGObject library is to fully support GObject introspection and all its features, including callbacks, closures, GVariant support, etc.

A complete set of Python bindings

PyGObject is a fairly complete set of Python bindings, which is very useful and can be used to write simple and complex programs (see the examples directory in the tarball for some random, yet simple examples of programs you could write using this library).

Under the hood and availability

The library is written entirely in the Python programming language, which means that it can be easily installed on any GNU/Linux operating system where Python is available. Because of this, it can be downloaded from Softoware as a universal source archive, which requires you to configure and compile the program prior to installation.

Mandatory requirements

It is very important to mention here that in order to compile the PyGObject library on your Linux kernel-based operating system, you will be to have a supported C compiler (GCC or MSVC), Python 2.7 or higher, GLib and Gio 2.38.0 or higher, gobject-introspection 1.38.0 or higher, as well as the libffi library, which is optional at the moment.

Installation instructions

To install the PyGObject, you will have to execute the “./configure --prefix= && make && make install” command in a terminal emulator, considering the fact that you are logged in as root (system administrator). On some GNU/Linux distributions, you can easily install the library from its default software repositories. Both 32-bit and 64-bit architectures are supported at this time.
