API

header(text, data)

text

Type: String Default: ''

The template text.

data

Type: Object Default: {}

The data object used to populate the text.

In addition to the passed in data, file will be the stream object for the file being templated against and filepath will be the path relative from the stream's basepath.

NOTE: using false will disable template processing of the header
