Code snippet

Placeholder identifiers

Placeholders are usually indicated by some special character or sequence of characters to distinguish them from the rest of the snippet text. Some systems allow snippet placeholders to be named identifiers. The identifiers may be useful for supporting such features as placeholder duplication or placeholder transformation.

The following example uses the identifiers first_name, last_name, and item:

Hello {%first_name%} {%last_name%},

Your shipment of {%item%} is now ready to pick up.

Thanks {%first_name%}!
