Template:Substitution/doc

Not to be confused with Template:Subst or Template:Substituted.

Usage

Add this message box to a template's documentation to briefly explain the rules of substitution for the template.

Parameters

Add the first parameter by adding a pipe (|) followed by the text you wish to display bolded and in a larger font. This parameter inserts your chosen text, such as "always" or "never," in the middle of "should" and "be."

To have no text in the middle of "should" and "be," add a space after the first pipe.

The second parameter is optional. To use it, add a second pipe (|) followed by the text you wish to add to the end of the sentence. Note that you should not include ending punctuation at the end of the text you put in this parameter. The template will always include a full stop (a period) at the end for you.

Examples

With middle text but no additional text at the end

{{Substitution|not}}

produces:

With both middle text and additional text at the end

{{Substitution|only (at least as of 2024)|if temperatures fall and it starts to snow}}

produces:

With no middle text but some additional text at the end

Note the double pipe for the second parameter.

{{Substitution| |if you wish to ensure your emoji's image remains the same even if its template's image is changed}}

produces:
