Module:Transcluder/doc
This is the documentation page for Module:Transcluder
This Lua module is used on approximately 3,000 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own Module:Transcluder. Consider discussing changes on the talk page before implementing them. |
This module is a general-purpose transclusion engine, able to transclude any part of any page and with many options that normal transclusion doesn't provide.
Usage
Modules
The main entry point for modules is the get
method.
get( 'Title' )
— Get the requested page (exact same result as normal transclusion)get( 'Title#' )
— Get the lead section of the requested pageget( 'Title#Section' )
— Get the requested section or <section> tag (includes any subsections)
<noinclude> and <onlyinclude> tags are handled the usual way and there's also an optional second parameter to exclude various elements from the result:
get( 'Title#Section', { files = 0 } )
— Exclude all filesget( 'Title#Section', { files = 1 } )
— Exclude all files except the firstget( 'Title#Section', { files = 2 } )
— Exclude all files except the secondget( 'Title#Section', { files = '1,2' } )
— Exclude all files except the first and secondget( 'Title#Section', { files = '1-3' } )
— Exclude all files except the first, second and thirdget( 'Title#Section', { files = '1,3-5' } )
— Exclude all files except the first, third, fourth and fifthget( 'Title#Section', { files = -2 } )
— Exclude the second fileget( 'Title#Section', { files = '-2,3' } )
— Exclude the second and third filesget( 'Title#Section', { files = '-1,3-5' } )
— Exclude the first, third, fourth and fifth filesget( 'Title#Section', { files = 'A.png' } )
— Exclude all files except A.pngget( 'Title#Section', { files = '-A.png' } )
— Exclude A.pngget( 'Title#Section', { files = 'A.png, B.jpg, C.gif' } )
— Exclude all files except A.png, B.jpg and C.gifget( 'Title#Section', { files = '-A.png, B.jpg, C.gif' } )
— Exclude A.png, B.jpg and C.gifget( 'Title#Section', { files = { [1] = true, [3] = true } } )
— Exclude all files except the first and thirdget( 'Title#Section', { files = { [1] = false, [3] = false } } )
— Exclude the first and third filesget( 'Title#Section', { files = { ['A.png'] = false, ['B.jpg'] = false } } )
— Exclude A.png and B.jpgget( 'Title#Section', { files = '.+%.png' } )
— Exclude all files except PNG files (see Lua patterns)get( 'Title#Section', { files = '-.+%.png' } )
— Exclude all PNG files
The very same syntax can be used to exclude many other elements:
get( 'Title#Section', { sections = 0 } )
— Exclude all subsectionsget( 'Title#Section', { sections = 'History, Causes' } )
— Exclude all subsections except 'History' and 'Causes'get( 'Title#Section', { lists = 1 } )
— Exclude all lists except the firstget( 'Title#Section', { tables = 'stats' } )
— Exclude all tables except the one with id 'stats'get( 'Title#Section', { paragraphs = '1-3' } )
— Exclude all paragraphs except the first, second and thirdget( 'Title#Section', { references = 0 } )
— Exclude all referencesget( 'Title#Section', { categories = '0' } )
— Exclude all categoriesget( 'Title#Section', { templates = '-.+infobox' } )
— Exclude infobox templatesget( 'Title#Section', { parameters = 'image' } )
— Exclude all parameters from all templates except the one named 'image'
Options can be combined at will. For example:
get( 'Title#Section', { sections = 0, files = 1, paragraphs = '1-3' } )
— Exclude all subsections, all files except the first, and all paragraphs except the first three
You can also get only some elements like so:
get( 'Title#Section', { only = 'files' } )
— Get only the filesget( 'Title#Section', { only = 'lists', lists = 1 } )
— Get only the first listget( 'Title#Section', { only = 'tables', tables = 'stats' } )
— Get only the table with id 'stats'get( 'Title#Section', { only = 'paragraphs', paragraphs = '1,3-5' } )
— Get only the first, third, fourth and fifth paragraphget( 'Title#Section', { only = 'templates', templates = 'Infobox' } )
— Get only the infobox
The output can be further modified with a few special options:
get( 'Title#Section', { noFollow = true } )
— Don't follow redirectsget( 'Title#Section', { linkBold = true } )
— Link the bold title or synonym near the start of the textget( 'Title#Section', { noBold = true } )
— Remove bold textget( 'Title#Section', { noSelfLinks = true } )
— Remove self linksget( 'Title#Section', { noBehaviorSwitches = true } )
— Remove behavior switches such as__NOTOC__
get( 'Title#Section', { fixReferences = true } )
— Prefix reference names with 'Title ' to avoid name conflicts when transcluding and rescue references defined outside the requested section to avoid undefined reference errors
Besides the get
method, the module exposes several other methods to get specific parts of the wikitext. This allows other modules to combine elements in more advanced ways.
Templates
The main entry point for templates is the main
method. It's essentially a wrapper of the get
method to make it usable for templates. See the documentation of the get
method for more details and options.
