Elixir Idioms and Patterns

Elixir rewards immutability, pattern matching, and the OTP supervision model. Idiomatic Elixir = functional, fault-tolerant, process-oriented.

Scope: Elixir coding idioms. Test naming: .agents/rules/testing-strategy.md.

Pattern Matching

1. Pattern match everything — function heads, case, with:

   def handle_result({:ok, task}), do: {:reply, task}
   def handle_result({:error, :not_found}), do: {:error, 404}
   def handle_result({:error, reason}), do: {:error, 500, reason}
