April 2023 Meeting
The April 2023 meeting of LRUG will be on Monday the 17th of April, from 6:00pm to 8:00pm (meeting starts at 6:30pm). Note this is later in the month than we would normally hold the meeting, due to the Easter bank holiday.
This month we're hosted again by the lovely folk at Cleo at their offices, in Shoreditch. Full venue and registration details are given below.
Making a working upwards assignment operator
Ruby has leftward assignment. It has rightward assignment. But what about upward assignment?
In this talk, we’ll misuse Ruby’s internals to build an arrow operator that lets us assign upwards. We’ll see some powerful Ruby metaprogramming features that allow us to bend Ruby to our will – and we’ll talk about why it’s good to write code that’s just plain daft.
Build a mini Ruby debugger in under 300 lines
Stan Lo says:
As developers, we know that the best way to learn is by doing. Many of us have built mini-rails, mini-sinatra, and even mini-rubies. But have you ever built your own debugger?
In this talk, I'll show you how to create a mini Ruby debugger that's both powerful and fun to use. You'll learn how to: - Run your program with debugger with a simple command - Set breakpoints and through debugger commands - Step through your code to find bugs
And best of all, you'll do it all in under 300 lines of code!
Once we're done with the talks we'll leave the venue (after doing our best to help tidy up) and find a local pub for to eat, drink, and discuss the talks we've just heard.
Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.
