In plain words
This is Werner's personal website featuring documentation tools and educational projects. It includes d.awk, an AWK script that extracts Markdown-formatted documentation from source code comments in languages like C, C++, and Java. The site also documents wregex, a regular expression engine written in 2007 and later cleaned up for GitHub. The site serves as a portfolio for coding projects and technical writing about software development.

Hi, I recently published my ebook on GNU awk one-liners [1]. It starts from the basics of awk syntax and then discusses one-liner examples. There's a chapter on regular expressions as well. The github repo has the details on how to get the PDF version, all the example files and code snippets used in the book, sample chapters as well the markdown source used to generate the PDF. I made all my ebooks [2] free last month amidst the pandemic fears. These include GNU grep & ripgrep, GNU sed and three books on regular expressions (Python, Ruby, JavaScript). I'd appreciate your feedback and hope…
