HEEx is a templating engine on top of Elixir's EEx templating language specific to HTML that is included in Phoenix.LiveView (though I think the plan is to eventually include it in base Phoenix). It's a superset of EEx with some additional features like components and slots. The injections don't work perfectly because the Elixir grammar is newline sensitive (the _terminator rule). See https://github.com/elixir-lang/tree-sitter-elixir/issues/24 for more information.
