fpTemplate unit

fpTemplate implements a class TTemplateParser which can replace variables in a template text. The template variables are enclosed in delimiters. When a variable is encountered, it can be replaced by a string value. An event is called to get the value for a template variable. It does not contain loops or conditionals, but parametrized templates are possible.

The unit also contains TFPCustomTemplate and its descendant TFPTemplate. Which is a basic implementation that uses the template parser to substitute variables in a text.
