Module:CopyEmbeddedStories

This module extracts all instances of the `EmbeddedStory` template from a specified source page. It is useful for retrieving and reusing embedded story elements across different pages in a MediaWiki environment.

Usage

The module can be invoked using `#invoke` in a template or wiki page.

{{#invoke:CopyEmbeddedStories|fetchEmbeddedStories
 | sourcePage=ExamplePage
}}

Parameters

• `sourcePage` - The title of the wiki page from which `EmbeddedStory` templates should be retrieved.

Behavior

1. The module reads the raw wikitext content of the specified `sourcePage`. 2. It searches for all instances of `Template:EmbeddedStory ...` within the page. 3. The found templates are returned as a newline-separated list. 4. If the page is not found or empty, an error message is returned.

Example Output

If `ExamplePage` contains:

{{EmbeddedStory|Title=Story 1}}
Some text here.
{{EmbeddedStory|Title=Story 2}}

Then the module will return:

{{EmbeddedStory|Title=Story 1}}
{{EmbeddedStory|Title=Story 2}}

Notes

• The module does not modify the extracted templates; it simply returns them as raw wikitext.
• If no `EmbeddedStory` templates are found, it returns an empty string.
• If `sourcePage` is not specified, an error message is displayed.
