Eml.Parameter

Parameters are placeholders for values in a template or block of eml.

A parameter is created automatically whenever an atom is encountered in a block of eml. Binding a value to a parameter can be done in several ways in Eml. Depending on the use case, you can use Eml.Template.bind/2, Eml.Template.bind/3, Eml.compile/3, or Eml.render/3.

Examples

iex> e = Eml.to_content(:a_parameter)
#param:a_parameter
iex> Eml.render(e, a_parameter: "a value")
"a value"

iex> use Eml.Language.HTML
iex> e = p [id: :some_id], :content
#p<%{id: #param:some_id} [#param:content]>
iex> t = Eml.compile(e, some_id: 42)
#Template<[:content]>
iex> t = Template.bind(t, content: "some content")
#Template<BOUND>
iex> Eml.render(t)
"<p id='42'>some content</p>"
