Children

If a tag is empty, you can close it with />, like XML:

<div />

otherwise, it can contains children:

<div>
  <h1>Hello World!</h1>
  <img src="hello.png" />
  This is a text
</div>

Expressions as children

You can also embed expressions in children, these expressions can produce std::string, asmdom::VNode or asmdom::Children.

Strings

std::string can be embed using double curly brackets:

// std::string name = "foo";

<div>
  <h1>Hello {{ name }}!</h1>
</div>

VNode

asmdom::VNode can be embed using single curly brackets:

/*
asmdom::VNode getImg(std::string src) {
  return <img src={src} />;
};
*/

<div>
  <h1>Hello World!</h1>
  { getImg("hello.png") }
</div>

Children

asmdom::Children can be embed using {...expression}:

/*
asmdom::Children getVNodes(std::string src) {
  return asmdom::Children {
    <img src={src} />,
    <div>Rendering {{ src }}</div>
  };
};
*/

<div>
  <h1>Hello World!</h1>
  {...getVNodes("hello.png")}
</div>

NULL children

If you want to conditionally render something, CPX accepts NULL values:

// std::string name = "foo";
<div>
  <h1>Hello World!</h1>
  { name === "foo" ? <h2>Hi Foo!</h2> : NULL }
</div>
