LuaWiki – Module with functions for Lua programming in context of a Wiki project.

Functions for templates

No direct usage by templates.

Functions for Lua modules (API)

Transclusion into own module via require() as follows:

local LuaWiki = require( "Module:LuaWiki" )
if type( LuaWiki ) == "table" then
    LuaWiki.setFrame( frame )
else
    -- appropriate error management; e.g. message within functions for templates
end

Thereafter the functions can be accessed; do not forget initialization.

LuaWiki.getArg( arg, assign )

Retrieve template argument

• arg – string or number; argument identifier
• assign – optional; default value of any type, if not provided in template transclusion
• Returns: string (ensured) or default value orherwise

If not set in template transclusion and no default value, then: {{{<arg>}}}

LuaWiki.getVariable( seek, numeric )

Retrieve item from wikiVariables; populate if not yet present; see de:Hilfe:Variablen

• seek – string; name of variable, like "PAGENAME"
• numeric – boolean, optional; true: seek is numeric (else string)
• Returns: string or number

Previous initialization with initVariables accelerates but ist not mandatory.

LuaWiki.initVariables( request )

Initialization of some required variables for acceleration

• request – table; selection of variables

  every element either:

  • string; name of variable, like "PAGENAME"
  • table; variable is always returned as numerical value
    • [1] string; name of variable
    • [2] true

• Returns: none

LuaWiki.isExisting( seek )

Test page existence; like #ifexist

• seek – string; full page name
• Returns: boolean

LuaWiki.setFrame( frame )

Initialize frame for this utility by current template environment

• frame – frame object
• Returns: none

LuaWiki.transclude( s, args )

Save transclusion of a page, or error message

• s – string; full page name (if namespace not provided Template: will be used)
• args – table, optional; arguments
• Returns: string; transclusion or error message if page missing

The initialization is important: On start the frame object of current template environment needs to be set by LuaWiki.setFrame( frame ) – this won’t be checked any more.

Usage

General library; no limitations.

Dependencies

None.
