RubyConf 2021 - debug.gem: Ruby's new debug functionality by Koichi Sasada
This talk introduces ruby/debug: Debugging functionality for Ruby, a completely rewritten debugger for Ruby and it will be shipped with Ruby 3.1 at next Christmas.
The new debugger has several advantages:
Fastest debugger: Using recent introduced TracePoint features and (almost) no penalty on normal execution.
Remote debugger
Native VSCode (DAP) integration
Easy integration with applications
Thread/Ractor support
And more useful features!
In this talk, I'll introduce useful features of this new debugger and tips for Ruby development.
