Module:Mw.html extension

Module documentation

This documentation is transcluded from Module:Mw.html extension/doc. [edit] [purge]

Module:Mw.html extension requires Module:LibraryUtil.

Module:Mw.html extension is required by Module:Helper module.

This module is a helper module to be used by other modules; it may not designed to be invoked directly. See RuneScape:Lua/Helper modules for a full list and more information. For a full list of modules using this helper click here

Module	Function	Type	Use
Mw.html extension	addClassIf(cond, class)	boolean, string	If cond = true it behaves the same as the normal addClass function, otherwise it's a no-op. Ex.: mw.html.create('div'):addClassIf(true, 'align-left-1')
	attrIf(cond, name, value)	boolean, string/table, string/nil	Similar to addClassIf
	cssIf(cond, name, value)	boolean, string/table, string/nil	Similar to addClassIf
	doneIf(cond)	boolean	Similar to addClassIf
	tagIf(cond, tag)	boolean, string	Similar to addClassIf
	wikitextIf(cond, text)	boolean, string	Similar to addClassIf
	na()	N/A	Shortcut for :tag('td'):attr('data-sort-value', 0):attr('class','table-na'):wikitext('<small>N/A</small>'):done()
	naIf(cond)	boolean	Similar to addClassIf
	IF(cond)	boolean	Allows for if-blocks without breaking the chain. If the condition is true it is a no-op, if false everything inside the balanced IF-END block will be ignored. Can be nested. Ex.: mw.html.create('div') :IF(true) :wikitext('Conditional text') :END() :...
	ELSE()	N/A	Used together with IF().
	END()	N/A	Used together with IF(). Make sure the IF-END tags are balanced, it wont throw an error if they are not.
	exec(func, ...)	function, any	Call a function without breaking the chain. See module docs for more info.
	addFunction(func, name)	function, string	Add a function to the mw.html class that can then be used on mw.html object. See module docs for more info.

Usage

For all functions other than addFunction() all you need to do is simply require this module:

require('Module:Mw.html extension')
local p = {}

function p.main()
    ...
    local tbl = mw.html.create('div')
        :IF(true)
            :wikitext('Conditional text')
        :ELSE()
            :wikitext('something else')
        :END()
        :addClassIf(true, 'wikitable')
        :tag('span)'
            :wikitext('normal wikitext')
        :done()
    ...
end

return p

You can mix the normal old functions with the newly added ones.

attrIf

This accepts either a name-value pair or a table

• :attrIf(true, 'data-sort-value', '0')
• :attrIf(true, {'data-sort-value' = '0', ...})

cssIf

This accepts either a name-value pair or a table similar to attrIf

exec

The first parameter of the function will have the current state of the mw.html object passed into it, usually we call this parameter self, the rest of the parameters can be anything you want. To not break the chaining the function must also return a mw.html object. Example:

local function repNa(self, times)
    for i = 1,times do
        self:na()
    end
    return self
end

This function can then be used as follows

mw.html.create('div'):exec(repNa, 5)

addFunction

The function you want to add has to be of the same structure as in exec(). Example:

local htmlExtension = require('Module:Mw.html extension')
local p = {}

local function repNa(self, times)
    for i = 1,times do
        self:na()
    end
    return self
end
htmlExtension.addFunction(repNa, 'repNaName')

function p.main()
    ...
    local tbl = mw.html.create('div'):repNaName(5)
    ...
end

return p
