   Hi, all!
   
   Since version 1.6 elixir provides built-in code formatter which refers most of code style issues.
   The goal of the formatter is to automate the styling of codebases into a unique and consistent layout used across teams and the whole community.
   
   It has several options useful for CI and development:
   `--check-formatted` - checks that the file is already formatted.
   `--check-equivalent` - checks if the files after formatting have the same AST as before formatting. If the ASTs are not equivalent, it is a bug in the code formatter. This option is recommended if you are automatically formatting files.
   
   If any of the --check-* flags are given and a check fails, the formatted contents won’t be written to disk nor printed to standard output.
   
   So, perhaps, it make sense to adopt formatter firstly.
