Global VAriable

Tamper perfection with bloat.

Motivation

• Immutability? Good.
• Mutability? Bad.

When writing a script in Elixir you may need a global scope to save data. Sure you can send(self(), {:result, 42}) but it adds annoying overhead to get the sent data. A GenServer can be used but it's worst in term of overhead and absolutely overkill.

GVA is simple and tries to have the smaller footprint when writing scripts: no module or local function to create, etc. Just an import.

Installation

In your elixir script:

Mix.install([:global_variable])
import GVA

Notes

• Elixir 1.12 is needed (then/1 and Mix.install/1)
