Class: ExpressTemplates::Components::NullWrap

Defined in:
lib/express_templates/components/null_wrap.rb

Overview

NullWrap is useful for creating a node in the component tree that does not produce any markup. It can be used in a template fragment to wrap bare text or string content where such would not normally be possible.

Example:

“‘ruby div {

some_component
null_wrap {
  "Some text"
}
other_component

} “‘

Otherwise you can use it to hold already-complied code meant for evaluation in the view that needs to be protected from being compiled again. This use is largely internal to express_templates. It is not expected that users of this library would need this.

Example:

“‘ruby null_wrap(“(@collection.map do |member| "<li>#membermember.name</li>").join”) “`
