Hello!

I am pleased to announce a new version of my "Understanding Ruby Regexp" ebook. This book will help you learn Ruby Regular Expressions step-by-step from beginner to advanced levels with hundreds of examples and exercises.

Links:

• Free PDF/EPUB: https://learnbyexample.gumroad.com/l/rubyregexp
• Web version: https://learnbyexample.github.io/Ruby_Regexp/
• Markdown source, exercise solutions, etc: https://github.com/learnbyexample/Ruby_Regexp
• Short video about the book: https://youtu.be/QNsCzVeZH78

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 :)

What the title says. It's <1k lines of Ruby, and provides a basic tiling WM w/some support for floating windows. It's minimalist, likely still buggy and definitely lacking in features, but some might find it interesting.

It is actually the WM I use day to day

Whichlang is a rust library that detects languages. There were no Ruby bindings so I made one.

For any ruby devs looking to use crystal as well

Just pushed this to Github and Rubygems. I use this for my Ruby editor. It parses the GtkSourceView style XML files if you have GtkSourceView installed, and instantiates Rouge themes for them (Rouge is used by e.g. Gitlab) so you get access to some more themes. It's not perfect because it needs to try to map token types between the GtkSourceView and Rouge lexers, but overall works pretty well.

One of the terminals is st - the Ruby terminal is a bit wobbly in a few respects still, though I use it more and more. So there are a few non-Ruby bits left. So far. >

All of this is messy and buggy and may have dependencies on my environment that haven't been fixed yet, but I thought it'd be fun to show how much you can run on Ruby (I rely on most of these day to day)

The font renderer (used for the desktop manager, menu and the Ruby terminal, the lower left window is st using FreeType; I should've excised that from the screenshot :-) ) https://github.com/vidarh/skrift

The X11 bindings (no xlib; pure Ruby) https://github.com/vidarh/ruby-x11

X bindings for the font renderer: https://github.com/vidarh/skrift-x11

This is not what the terminal code looks like any more; that version used a C-extension, but that's the repo the current version will eventually get pushed to: https://github.com/vidarh/rubyterm

The menu is not on Github yet, but it's fed menu items from a somewhat updated version of this gist - a new version will be up at some point: https://gist.github.com/vidarh/323204137de5293bfe216ec751646525

An out-of-date-and-probably-won't-run-on-your-system version of my text editor (not least it depends on helper scripts I've not yet untangled from my personal setup). The repo will soon be updated: https://github.com/vidarh/re
