There is a great Elixir extension support for Visual Studio Code and there are currently 2 extensions to add the language to the tool, my preference being vscode-elixir. You can add it by hitting ctrl+P then typing “ext install vscode-elixir”.
This extension adds rich elixir language support to VS Code including:
- Syntax Coloring
- Snippets
- Intellisense
There is also a sublime integration called ElixirSublime. It has most of the same features. However, it hasn’t been updated in many years.
