^value( expression )^

^value(expression)^

The argument to ^value^ is an expression — a value that could be assigned to an attribute. ^value^ evaluates the expression and exports the result, as a string. This allows manipulations for export use without needing to, for instance, hold the value in a user attribute first.

^value^ is in effect a version of ^get^/^getFor^ but which allows the called attribute's value to be manipulated. For example:

^value($Width)^

exports the width of the current note, and is equivalent to

^get(Width)^

So you may use the two forms interchangeably even where no manipulation of the target attribute is required.

More examples:

^value(sqrt($Width))^

^value("Name: "+$Name)^

^value($Name+":"+$Name(parent))^

See also ^action (action )^.

You don't need to use ^value^ explicitly internally for actions and rules as the expanded v4+ syntax already covers this.
