What are they?
Expressions are a mechanism for the autocompletion of values which may not be known until build execution time (most common example of this would be the current build number). They can also be used to autocomplete variables.
Where can I use them?
Expressions can be utilised in several dialog fields throughout Continua (they are especially useful within stage actions, and build event handlers).
The expansion icon (below) denotes fields that have expression capabilities.
Expression Expansion
To initiate an expansion simply type the dollar symbol '$' and the expression auto complete will present (note: not all objects are available in all fields).
