Module:Call wikitext: Difference between revisions

Module documentation[view] [edit] [history] [purge]

Implements {{Call wikitext}}. This module was originally designed for providing an effective way to create testcases for Module:ArgRest, by "mocking" a transcluded template.

Usage

This module can also be used directly. See Template:Call wikitext/doc for documentation and replace {{Call wikitext with {{#invoke:Call wikitext|main. For example:

• {{Call wikitext|sourceCode=<nowiki>{{{foo}}}</nowiki>|foo=Hello!}} →

• {{#invoke:Call wikitext|main|sourceCode=<nowiki>{{{foo}}}</nowiki>|foo=Hello!}} → Hello!

The above documentation is transcluded from Module:Call wikitext/doc. (edit | history)
Editors can experiment in this module's sandbox (create | mirror) and testcases (create) pages.
