Learning Cython Programming (Second Edition) - Second Edition

By: Philip Herron

Overview of this book

Cython is a hybrid programming language used to write C extensions for Python language. Combining the practicality of Python and speed and ease of the C language it’s an exciting language worth learning if you want to build fast applications with ease. This new edition of Learning Cython Programming shows you how to get started, taking you through the fundamentals so you can begin to experience its unique powers. You’ll find out how to get set up, before exploring the relationship between Python and Cython. You’ll also look at debugging Cython, before moving on to C++ constructs, Caveat on C++ usage, Python threading and GIL in Cython. Finally, you’ll learn object initialization and compile time, and gain a deeper insight into Python 3, which will help you not only become a confident Cython developer, but a much more fluent Python developer too.

Extending Tmux


Tmux is a terminal multiplexer inspired by GNU Screen (http://tmux.github.io/), but it supports much simpler and better configuration. More importantly, the implementation is much cleaner and easier to maintain, and it also uses libevent and very well-written C code.

I want to show you how you can extend Tmux with new built-in commands by writing Python code instead of C. Overall, there are several parts to this project, as follows:

  • Hack the autotool's build system to compile in Cython

  • Create PXD declarations to the relevant declarations such as struct cmd_entry

  • Embed Python into Tmux

  • Add the Python command to the global Tmux cmd_table

Let's take a quick look at the Tmux source, and in particular any of the cmd-*.c files that contain command declarations and implementations. Consider, for example, that cmd-kill-window.c is the command entry. This tells Tmux the name of the command, its alias, and how it may or may not accept arguments; finally, it accepts a function pointer to the...
