Modulinfo

Dieses Modul setzt die Vorlage:Infobox um. Anweisungen zur Verwendung findest du auf der Vorlagenseite.

Dies ist ein Metamodul, welches zur Erzeugung verschiedener Infoboxen verwendet wird.

--- Allows to add arbitrary rows from template args
--- @param args table Template arguments
--- @param prefix string|nil An optional prefix that each argument must have to be added as a row
--- @param allowedKeys table|nil An optional table of keys that are allowed as rows, are passed to ustring.match
---
--- Example param = !row -> Only Template arguments in the form of |!row...=Content are added as Rows
--- The prefix gets replaced from each key: |!rowLabel=Content  => Label=Content
---
--- The row type can be set by adding 'subheader' or 'header' to the key
--- Example: |header1=Content => Header row with content 'content' added
--- Multiple headers must be suffixed by numbers
---
--- !!! NOTE !!!
--- Lua tables do not preserve order, to mitigate this, this module SORTS the given arguments ALPHABETICALLY
--- You can prefix arguments with numbers to preserve the order
--- Example Template:
--- {{Infobox
--- |1-header=Header for block one
--- |1.1-RowLabel=This is the content for row 1.1
--- |1.2-RowLabel=This again is the content
--- |2-subheader=Subheader
--- |2.1-Label=Content
--- |2.2...
--- }}

--- Example Module Call:
--- infobox.addRowsFromArgs({
---   [ '1-header' ] = 'Header for block one',
---   [ '1.1-RowLabel' ] = 'This is...',
