Hi Everyone, I started on a series to learn by reversing a native Ruby gem. Part 4 is now published! This does a deep dive into the makefile that you would use during development and also how it can be made to work properly also on Windows. Part 4 - https://notepad.onghu.com/2023/learning-by-reversing-s1-e4-native-gems/ The first 3 parts are also online on my blog: * Part 1 - This covers the background to the gem we explore Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e1-native-gems/ * Part 2 - This goes into the details of how ruby loads the native gem and extension (and includes a nice sequence diagram of how all the bits happen together) Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e2-native-gems/ * Part 3 - How do we ensure that we have everything and that it actually gets built at installation? Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e3-native-gems/ Future posts are planned to go into details like: * The interface between Ruby and C * Running the specs and the performance benchmark * Enhancements: - Providing an executable - A gem that also works on JRuby - Making the gem ractor friendly - Patching an existing gem rather than a new module Comments on the posts or the plans welcome. I'm @onghu on Twitter or @onghu@ruby.social on Mastodon if you're on either. Best regards, Mohit.
