Remote memory profiling with Memray

Memray is a memory profiler for Python, built by some very smart devs at Bloomberg. It is a fantastic tool to identify memory leaks in your code or other libraries (down to the C level)!

They recently added a Textual interface which looks amazing, and lets you monitor your process right from the terminal:

Things I learned building a text editor for the terminal

TextArea is the latest widget to be added to Textual's growing collection. It provides a multi-line space to edit text, and features optional syntax highlighting for a selection of languages.

Adding a TextArea to your Textual app is as simple as adding this to your compose method:

yield TextArea()

Enabling syntax highlighting for a language is as simple as:

yield TextArea(language="python")

Working on the TextArea widget for Textual taught me a lot about Python and my general approach to software engineering. It gave me an appreciation for the subtle functionality behind the editors we use on a daily basis — features we may not even notice, despite some engineer spending hours perfecting it to provide a small boost to our development experience.

This post is a tour of some of these learnings.
