title: get Operator
type: text/vnd.tiddlywiki
caption: get
purpose: select all values of a field in the input titles

<$macrocall $name=".operator-def"
input="a [[selection of titles|Title Selection]]"
parameter="the name of a [[field|TiddlerFields]]"
paramName="f"
output="the values of field <<.place f>> in each of the input titles"
/>

Each input title is processed in turn. If the corresponding tiddler contains field <<.place f>>, and the value of this field is not empty, then its value is appended to the output.

Unlike most other [[Filter Operators]], the [[selection|Title Selection]] output by <<.op get>> can contain duplicates. To avoid duplicates, use `each[f]get[f]`.
