Typical features

Template engines typically include features common to most high-level programming languages, with an emphasis on features for processing plain text

Plain text

In computing, plain text is the contents of an ordinary sequential file readable as textual material without much processing, usually opposed to formatted text....

.

Such features include:

variable

s and functions
text replacement
file inclusion (or transclusion

)
conditional evaluation and loops

Example

The accompanying illustration depicts a simplified processing model for a typical web template engine. The template engine produces a web page by processing the web template source file along with data from a relational database

Relational database

A relational database is a database that conforms to relational model theory. The software used in a relational database is called a relational database management system . Colloquial use of the term "relational database" may refer to the RDBMS software, or the relational database itself...

. The template engine replaces variables with specific values. In the illustration, substitution of $X by the database content (in page 01 "Mother", on page 02 "World").

A web template

Web template

might look like this:





   Hello {$X}

With additional template source code ...



templateAssign ('X', 'World');

... or, when specifying the relational database context:



$data[01]='Mother';  $data[02]='World';

templateAssign('X', $data[$i]);

Benefits

Benefits of using template engines include:

Encouraging organization of source code into operationally-distinct layers (see e.g., MVC
Model-view-controller
Model–view–controller is a software architecture, currently considered an architectural pattern used in software engineering. The pattern isolates "domain logic" from the user interface , permitting independent development, testing and maintenance of each .Model View Controller...

)
Enhancing productivity by reducing unnecessary reproduction of effort
Enhancing teamwork by allowing separation of work based on skill-set (e.g., artistic vs. technical)
