Module:DemoTemplate

Usage

Simply place "#invoke:DemoTemplate|" before a call to a template. For example, {{#invoke:DemoTemplate|Convert|10|km|nmi|abbr=off}} yields the following:

This module handles both named and positional parameters as well as equals signs in both parameter names and values correctly, so this (for example) will work: {{#invoke:DemoTemplate|1x|1=Some parameter with an = sign in it}}

Note, however, that pipes, curly braces, etc. are not currently handled correctly by this module, so this (for example) will not work correctly: {{#invoke:DemoTemplate|1x|foo{{!}}bar}}
