data-prototype VS TUI-apps

haha matplotlib devs and us are BFFs, matplotlib's new software engineer in residence is a pyqtgraph maintainer funny enough. We serve different purposes so you won't catch up speaking badly of each other. That said, they're working on a new "data-prototype" which may provide a way for us to have more compatible APIs.

Hello!

I am pleased to announce a new version of my "CLI text processing with GNU sed" ebook. This book heavily leans on examples to present features one by one. In addition to sed commands and options, regular expressions are also discussed in detail.

Links:

* PDF/EPUB versions: https://learnbyexample.gumroad.com/l/gnu_sed (free for a few days)

* Web version: https://learnbyexample.github.io/learn_gnused/ (always free)

* Markdown source, example files, etc: https://github.com/learnbyexample/learn_gnused

* Interactive TUI app for exercises: https://github.com/learnbyexample/TUI-apps/blob/main/SedExercises

I would highly appreciate it if you'd let me know how you felt about this book. It could be anything from a simple thank you, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors.

Happy learning :)

I also wrote an interactive TUI app based on some of the exercises from the ebook. Reference solutions are provided for both GNU grep and ripgrep.

This year I started updating my existing books and I'm also creating interactive apps. Here's one for Python regex: https://github.com/learnbyexample/TUI-apps/blob/main/PyRegexExercises. Next is grep.

Having an interactive program that automatically loads questions and checks the solution is wonderful to have while learning a topic. I wrote a TUI app that has beginner to advanced level exercises for Python regular expressions. There are more than 100 exercises covering both the builtin re and third-party regex modules.

My first app with Textual was a board game. Like Tic Tac Toe but make a square on a 4x4 board: https://github.com/learnbyexample/TUI-apps/tree/main/SquareTicTacToe

To make it easier to experiment, I'm currently working on an interactive app. See PyRegexPlayground repo for installation instructions and usage guide. A sample screenshot is shown below:

I also made an interactive TUI app with 40 cli text processing exercises - I plan to cover all the 200+ exercises sometime later this year.

I wrote an interactive CLI exercises TUI with textual a few weeks back. Having a fixed location to play with commands interactively felt nice and I did wonder if something like could be expanded to make a nice terminal alternative for some tasks.
