Module:Eval
Module DocumentationThis module/template provides the possibility to parse almost any Wiki text almost anywhere.
Usage
Eval in the following format refers to:
- Write
#invoke:Evalwhen using modules; - Write
Evalwhen using templates.
Expanding a template
{{ Eval | template | template name | parameter list... }}
- Parameters
- Template name: The name of the template to be expanded, without adding the Template:namespace prefix;
- Parameter list: all parameters of the template. The format is:
- parameter name = wikitext or wikitext;
- When the parameter name is a number (or does not display and write [parameter name]=), the parameter value can write the parameter text of multiple templates to be expanded, such as [template parameter 1]|[template parameter 2]|…. Finally, the numbered parameters will be concatenated in order to become the anonymous parameter list of the template to be expanded;
- When the parameter name is not a number, it will be equivalent to writing the parameter of the same name of the template to be expanded. These parameters will be concatenated after the anonymous parameter list.
