Declares new variables which are aliases of other variables. Takes a "map"-Parameter which is an associative array which defines the shorthand mapping.

The variables are only declared inside the <f:alias>...</f:alias>-tag. After the closing tag, all declared variables are removed again.

= Examples =

<f:alias map="{x: 'foo'}">{x}</f:alias>

foo

<f:alias map="{x: foo.bar.baz, y: foo.bar.baz.name}"> {x.name} or {y} </f:alias>

[name] or [name] depending on {foo.bar.baz}

Note: Using this view helper can be a sign of weak architecture. If you end up using it extensively you might want to fine-tune your "view model" (the data you assign to the view).
