Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Future of Ruby – AST Tooling
4 projects | dev.to | 14 Nov 2021
There are already some techniques capable of doing just this, by combining Parser with Unparser, but of course such things can only be done on Ruby files read in rather than in a REPL session which is where a lot more fun could happen.
How to write a compiler or interpreter in rust
8 projects | /r/rust | 26 Dec 2021
In terms of parsing style I suggest sticking with a hand-written recursive-descent parser. Parser generators seem appealing at first, but I always ran into annoying limitations when using them (I wrote one in Ruby myself as well, and used this for this project). Parsing combinators are useful for small inputs, but I find them difficult to use for anything but simple cases.
What are some alternatives?
