Due to Lua limitations, parameters are normally ordered randomly when the template is substituted. {{para|$params}} can be used in #invoke:Unsubst to list template parameters in order, comma-separated (e.g. <code>egg,bacon,sausage,cheese,spam</code>). Numbered parameters should be before others in the list. Any remaining parameters are tacked onto the end of the generated invocation.

Parameter aliases can be listed in {{para|$aliases}} (and shouldn't be listed in {{para|$params}}), and will be replaced automatically. Each alias and its replacement should be formatted as <code>alias>replacement</code>, and each of those pairs should be comma-separated (e.g. <code>œuf>egg,melt>cheese</code>). Note that this parameter can function with or without {{para|$params}}.

Parameter {{para|$flags}} can be used to modify other facets of the module's behaviour; entries are comma-separated. Valid flags are <code>override</code> (allows parameters in the #invoke: to take precedence over parameters in the original template invocation); <code>keep-whitespace</code> (prevents whitespace from being trimmed from unnamed parameters); and <code>remove-empty</code> (removes empty parameters).

These parameters can be manipulated using parser functions to provide more complicated options (note that in the parameters any parser function, or template or module invocation, should also have <code><nowiki>SAFESUBST:<noinclude /></nowiki></code>).

Parameter {{para|$template-name}} will override the subst'd templates name with the template name assigned to this parameter.
