Hello!

I am pleased to announce my thirteenth ebook Computing from the Command Line. This is the longest book I've published so far (203 pages) and it took me more than 7 months to complete the first version.

This ebook aims to teach Linux command line tools and Shell Scripting for beginner to intermediate level users. The main focus is towards managing your files and performing text processing tasks. Plenty of examples are provided to make it easier to understand a particular tool and its various features. Exercises at the end of chapters will help you practice what you've learned and solutions are provided for reference. I hope this ebook would make it much easier for you to discover CLI tools, features and learning resources than my own blundering experience.

Quoting from What's New In Python 3.11:

Atomic grouping ((?>...)) and possessive quantifiers (*+, ++, ?+, {m,n}+) are now supported in regular expressions. (Contributed by Jeffrey C. Jacobs and Serhiy Storchaka in bpo-433030.)

If you are not familiar with regular expressions, see my Understanding Python re(gex)? ebook to get started.

Hello!

I am pleased to announce my twelfth ebook Vim Reference Guide. This is intended as a concise learning resource for beginner to intermediate level Vim users. It has more in common with cheatsheets than a typical text book. Topics like Regular Expressions and Macros have more detailed explanations and examples due to their complexity. I hope this guide would make it much easier for you to discover Vim features and learning resources than my own blundering experience.

I posted a coding challenge in the tenth issue of learnbyexample weekly. I discuss the problem and various solutions in this blog post.

In this post, I review Automating Excel with Python by Michael Driscoll. From the introduction chapter of this book:

The purpose of this book is to help you learn how to use Python to work with Excel. You will be using a package called OpenPyXL to create, read, and edit Excel documents with Python. While the focus of this book will be on OpenPyXL, you will also learn about other Python packages that you can use to interact with Excel using the Python programming language.

TL;DR: Started and ended the year well, with a depressing period in the middle. Published three programming ebooks, several blog posts, started a newsletter, improved Twitter readership, read 80+ novels, and so on. Had a good year in terms of ebook sales 😇

I posted a coding challenge in the fifth issue of learnbyexample weekly. I discuss the problem and Python/Perl solutions in this blog post.

(2023-03-20) Update: This TUI app covers many more exercises compared to the GUI app discussed below.

Still confused about Python regular expressions? Grow your confidence with Understanding Python re(gex)? ebook (FREE this month!) and an interactive GUI app.

Inspired by Advent of Code, I'll also be posting 3 challenges per day on twitter for 25 days.
