Interface TemplateParameter

Duplicate, overriden template parameters, if any.

The parameter key with leading and trailing spaces removed.

This property is never an empty string, even for unnamed parameters.

The parameter text, starting with a pipe character (|).

For unnamed parameters, the key is not rendered.

Whether the parameter is unnamed.

The parameter value.

Trimming behavior depends on whether the parameter is named:

• Named parameters collapse leading and trailing spaces.
• Unnamed parameters retain leading and trailing spaces.

See https://en.wikipedia.org/wiki/Help:Template#Whitespace_handling.

Regardless, trailing linebreak characters are always removed.
