Lua Module Documentation

This module provides the backend implementations of the Ref templates.

Public Functions

ref.ref

Invocation entry point for Template:Ref. Takes arguments Id, Name, Group and Text from the template parser frame and constructs the appropriate reference.

Parameters:

• frame (object) - The current parser frame

Returns:

wikitext - the constructed reference

ref.list

Invocation entry point for Template:Ref/List. Takes argument Group from the template parser frame and constructs the appropriate reference list.

Parameters:

• frame (object) - The current parser frame

Returns:

wikitext - the constructed reference list

ref.generic

Invocation entry point for Template:Ref/Generic. Currently unimplemented.

Parameters:

• frame (object) - The current parser frame

Returns:

wikitext - the constructed reference

Private Functions

makeRef

Constructs a reference with the given text, using the provided parser frame, ref id and group.

Parameters:

• frame (object) - The current parser frame
• id (string) - The id to give to the reference
• group (string) - The group to include the reference in
• text (string) - The text of the reference

Returns:

wikitext - the constructed reference

makeStandardRef

Constructs a standard format reference using the given parameters, with the provided content. Content table supports unlimited numeric arguments, in addition to Section, Detail, Quote, Quotee and Suffix arguments.

Parameters:

• frame (object) - The current parser frame
• id (string) - The id to give to the reference
• group (string) - The group to include the reference in
• content (table) - The content of the reference

Returns:

wikitext - the constructed reference

makeRefText

Generates the text content of a standard format reference from the provided arguments. Content table supports unlimited numeric arguments, in addition to Section, Detail, Quote, Quotee and Suffix arguments.

Parameters:

• content (table) - The content of the reference

Returns:

wikitext - the constructed reference text

makeReuse

Constructs wikitext to reuse an existing reference with the given id, in the given group.

Parameters:

• frame (object) - The current parser frame
• id (string) - The id to give to the reference
• group (string) - The group to include the reference in

Returns:

wikitext - the constructed reference reuse wikitext

makeList

Constructs the list of references in a given group.

Parameters:

• frame (object) - The current parser frame
• group (string) - The reference group to list
• colNum (int) - The number of columns to use in the list
• colWidth (int) - The width list columns should be
• colGap (int) - The size of the gap between list columns

Returns:

wikitext - the constructed reference
