13854 :: wanna share my Nim notes

  I started to collect and organize my Nim notes on my home page and I'd like to share it: https://arato.inf.unideb.hu/szathmary.laszlo/pmwiki/index.php?n=Acad.Nim2 . I set up an issue tracker too. If you notice a mistake, please let me know. This is still a work in progress.

  Some stuff looks cool, I like the idea progression in the table. Every time I go back to Nim, there are some basic stuff that I forget like blocks. It seems you have not dive into metaprogramming yet, it is fun! It is not func-> proc -> template -> macro but rather:

  • func -> proc (is there side-effects in my function? Yes, then it MUST be annotated proc)
  • func/proc -> generics -> template -> macro (Does my function behaves on similar types? Yes, then implicit generics are needed. Does my function need to have parameterized parameters or behaviour? Yes, then I need explicit genericity. Does my function needs to perfom term rewriting? Then a template. Does my function needs to parse code to adapt its behaviour? A macro is needed.

  It is quite a bit more complicated in practice, term rewriting is vague and there are other reasons.

  I'm fluent in Python, but I'm not an expert in Nim yet. So that's why I show lots of things in Python and in Nim, next to one another. "OK, in Python it looks like this. How to translate it to Nim?" The more I get used to Nim, the less I will have to consult these notes.

  Metaprogramming is advanced stuff. I want to dive into that later, when I know the basics of the language.
