Embedding a Python Application in uWSGI

The uWSGI logo WyWeb (my software that is running this website right now) uses uWSGI to communicate with the server. Previously, WyWeb was a loose collection of python files that needed to be run in a virtualenv and started with a separate uWSGI command and a configuration file. This was fine when WyWeb was fairly bare bones and only used by me, but as I began to expand its functionality, I wanted to easily share it with others. Having people clone a git repo, manage dependencies, manually set up systemd services, and configure a server is too much to ask. Luckily, I found uWSGI’s official documentation on how to embed a python script in a standalone binary! Unluckily, the instructions are out-of-date at best, objectively wrong at worst, and written in a tone so intolerable that I thought I had been catapulted back to the heckin’ epicsause year of our Lord 2010. Luckily for you I am recording my steps for success so that hopefully you can be spared the torment I have endured.

Writing a Simple Notcurses Program

Notcurses is a modern TUI library written by Nick Black (who you may see around the net as dankamongmen or some equally dank designation). As Dank himself will tell you, the older ncurses library is beautifully documented, rigorously tested, and very well supported. It is, however, quite old tracing its history back to at least 1982, and as such lacks some modern features such as thread-safety. I had been using the venerable ncurses for my fireplace program - a use case that it was never designed to handle. Overall ncurses does a good job, but there is occasional tearing and artifacts. Notcurses solved all the graphical glitches beautifully, and performance was noticeably improved. The problem is that just about the only other person using notcurses is Nick Black himself, and while his documentation is extensive, it is mostly source code snippets with few examples. Hopefully this article will provide a nice jumping-off point for the absolute beginner.
