I don’t understand why we need what looks like a double unquote of the
tag variable in the html_step2.exs macro. We create a macro for each html tag from the file. In the macro, we use
tag = unquote(tag) which in my understanding replaces
tag with it’s unquoted/injected value, but then it’s unquoted again in the
quote do: tag(unquote(tag)).
for tag <- @tags do defmacro unquote(tag)(do: inner) do tag = unquote(tag) quote do: tag(unquote(tag), do: unquote(inner)) end end
I’m certainly misunderstanding it as it compiles and works. But it’s confusing to me.
