Parse Elixir Module AST to replace functions and replace the original source file?
I am looking for a way to read in a elixir module and replace functions with code you want to run. Anyone know of any examples of code on how to parse a module’s AST to match against a function and replace it?
See example here: https://github.com/smorin/BootstrapEx
path = “lib/test_module.ex”
path
|> File.read!()
|> Code.string_to_quoted()
|> Insert.print()
path = “some_path”
path
|> get_file
|> get_ast
|> replace_function_that_matches_name
|> ast_to_string
|> string_to_file
|> format_file

TLDR: you can do this, but you can’t preserve code formatting, comments and other stuff which is not part of AST. I’ve been investigating a similar case here: Mix deps.add functionality
