Hello Julia Community,

I am happy to share a IJulia notebook describing **Julia Metaprogramming, Macros, and Generated functions** for people new to Julia like myself.

the notebook and associated figures can be found here:

Happy Coding,

Lance

Just an idea: you could use [GitHub - JuliaTeX/TreeView.jl: Draw Julia syntax trees as a graph](https://github.com/JuliaTeX/TreeView.jl) to visualize the expressions instead of having static `.png`s.

@tkoolen I am unfamiliar with the _TreeView.jl_, but always looking to learn. Appreciate the reference. I will have a look.

Thanks for this, it is really useful for beginners! I’ve never done any macro magic in Julia, because it sounds super esoteric to me, but reading your notebook really clarified a lot of stuff. I probably won’t be able to create macros still, but the concepts ant their meaning and certainly clearer.

Nice! That’s a good introduction for macros for newbies like me imho. 🙂
