Resources on Elixir AST

I made a prototype for CirruSepal for Elixir. In order to create AST the generate Elixir code, I need to know detail on Elixir AST. Here’s the docs I gathered.

Quote and unquote

Exampls in the docs is quite helpful:

iex> quote do: 1 + 2
{:+, [context: Elixir, import: Kernel], [1, 2]}
iex> quote do: sum(1, 2, 3)
{:sum, [], [1, 2, 3]}

Then I put some pieces togather so I can see it easily:

(
 ast = quote do: (
 for n <- [1, 2, 3, 4], do: n * n
 )
 IO.inspect ast
 IO.puts Macro.to_string ast
)

Quote and Unquote in Elixir

A bit more details can be found here, on `quote` and `unquote`:

iex> Code.eval_quoted(quote do: 1 + 2 * 3)
{7, []}

Elixir Macros by chrismccord

In this slide there’s a nice overview of AST of Elixir

Also this article, just a simple glance on how AST is working and used.

Understanding Elixir macros, Part 1 - Basics

Understanding Elixir macros, total 6 posts, I mainly focused on two of them:
`quote` `unquote` and `expansion`

Understanding Elixir macros, Part 3 - Getting into the AST

Talks on structure of AST, macro of `assert`

Ans this book is useful too.
