This week we’re talking to Marc-André Lafortune, a longtime contributor to the Ruby and Elixir communities, member of the Ruby and rubocop core teams including the core rubocop-ast engine, and creator of the backports gem.
This week we’re talking to Marc-André Lafortune, a longtime contributor to the Ruby and Elixir communities, member of the Ruby and rubocop core teams including the core rubocop-ast engine, and creator of the backports gem.
So there was this really awesome gem called parser written by someone not on the core team that gives you a super clean understanding of the Ruby code. Not only does it not care if the parentheses are there or not, but there's a really well structured and precise mapping of where the information comes from and it is completely semantic. So if you've got parentheses or not, it's not gonna make any difference in the structure of your abstract syntax tree, but you can actually ask where are the locations. That is taken care of, but the understanding of the code, what's going on in the code is completely independent of if you wrote those parentheses or not.
And that's really where it all started. We started using that parser gem and we wrote this tool called deep-cover, which was at the time the first branch covering tool. And it was a little bit crazy. Like if you raised an exception it would actually track that. It was pretty cool and about the same time, the core team was working on a similar tool in C so they both came out around the same time.
