▼ Description

The [Tag->Run] tag can be used to execute a tag or compound expression. Calling this tag is equivalent to calling a tag directly, but can be useful since parameters can be manipulated programmatically.

A reference to a tag can be retrieved through the \ symbol, the [Tags] map, or the [Null->Properties->Second] map of a data type.

Compound expressions can be created by surrounding a portion of LassoScript style code with braces {}. The compound expression can be stored in a variable or run using the [Tag->Run] tag.

The -Params parameter allows an array of parameters to be passed to the tag.

The -Name parameter allows the name of the tag which is being called to be passed to the tag. This parameter is required for built-in tags which rely on the name of the tag to determine what code to execute. Within a processing tag [Tag_Name] can be used to retrieve this value.

The -Owner parameter is required for member tag calls. It defines what data object the tag should act upon.

▼ Syntax

\TagName->(Run: -Name='tagname', -Params=(Array: ...))]

[Tags->(Find: 'tagname')->(Run: -Name='tagname')]

[Tags->(Find: 'tagname')->(Run: -Params=(Array: ...))]

[Array->Properties->Second->(Find: 'tagname')->(Run: -Params=(Array: ...), -Owner=(Array))]

[{ Return: 'Value' }->(Run)]

[Variable: 'myExpression' = { Return: 'Value' }]
[Output: $myExpression->(Run)]

▼ Parameters

Optional Parameters
-Params	The array of parameters which the tag should act upon. Defaults to the empty array if not specified.
-Name	The name of the tag to be called. Required for many built-in LDML tags.
-Owner	The data object which a member tag should act upon. Required for member tag calls.
