View Source EEx.SmartEngine (EEx v1.18.0-dev)
The default engine used by EEx.
It includes assigns (like @foo
) and possibly other
conveniences in the future.
Examples
iex> EEx.eval_string("<%= @foo %>", assigns: [foo: 1])
"1"
In the example above, we can access the value foo
under
the binding assigns
using @foo
. This is useful because
a template, after being compiled, can receive different
assigns and would not require recompilation for each
variable set.
Assigns can also be used when compiled to a function:
# sample.eex
<%= @a + @b %>
# sample.ex
defmodule Sample do
require EEx
EEx.function_from_file(:def, :sample, "sample.eex", [:assigns])
end
# iex
Sample.sample(a: 1, b: 2)
#=> "3"
