Note that the page lists and links to the set of expression objects available as from version 1.9.1 of Continua CI. For the list of expressions available to earlier versions see Expression Objects (1.9 and below).

What are they?

Expressions are a mechanism for the auto-completion of values which may not be known until build execution time (for example 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. Note is some areas, such as configuration variables, you can click on this icon to disable expressions

 


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).



Available Expression Objects

Different expression objects are available for each expandable field depending on which stage in the build process the expression will be evaluated at, and whether it will be evaluated on the server or an agent.
