Module:Infobox requires Module:Edit button.
Module:Infobox requires Module:SMW Utils.
Module:Infobox is required by .

Creating a template step-by-step

Import Module:Infobox and Module:Param Parse

local Infobox = require('Module:Infobox')
local parse = require('Module:Param Parse')

Unpack the frame arguments from the Template

local p = {}

function p.main(frame)
	local args = frame:getParent().args
	...

Setup the Module config settings

	local config = {
		infobox_name = 'Scenery',
		class = {Infobox.smw_param('episode')}, -- Add css class with episode name to colorize Infobox
	}

Map your arguments to parsing functions

Main article: Module:Param Parse

Use the params in Module:Param Parse to validate and format the data - feel free to create your own new params in Module:Param Parse. 

	local params = {
    	parse.name,
        parse.image,
		{name = 'description', func = parse.has_content, smw_property = 'Description'}, -- Custom param
        parse.episode,
 		...
	}

Define an Infobox object

Main article: Module:Infobox § new
	local infobox = Infobox.new(config, params, args)

Create your table

Main article: Module:Infobox § create
	infobox
		:add_row{
			{tag='th', content=Infobox.param('name'), class='infobox-header', colspan='20'},
		}
		:add_row{
			{tag='td', content=Infobox.param('image'), class='infobox-image', colspan='20'},
		}
		:pad("20")
		:add_row{
			{tag='td', content='Info', class='infobox-subheader', colspan='20'},
		}
		:pad("20")
		:add_row{
			{tag='th', content='Description', colspan="6"},
			{tag='td', content=Infobox.param('description'), colspan="14"},
		}
		:add_row{
			{tag='th', content='[[Episode]]', colspan="6"},
			{tag='td', content=Infobox.param('episode'), colspan="14"},
		}
		...


You're done!

	return infobox
end

return p

Functions

Special params

You don't need to do anything about these special parameters, but they may be used as parameters within the Template:

param explanation
version1, version2, version3 Button label and SMW name for each switch version of the infobox
default_version The default version to display when the page is loaded
version If there is only a single version, you can use version to set the SMW name (default SMW name is "DEFAULT")

Referring to params

Each parameter can have a different value for each version. In addition, there are 3 different representations of each value. Therefore, a parameter must be accessed via one of the 3 helper functions:

helper function example explanation
Infobox.raw_param(name) "1000" Raw value as passed by the Template
Infobox.param(name) "1,000" Value formatted for display in the Infobox
Infobox.smw_param(name) 1000 Value formatted to be saved as an SMW property

Infobox.new(config, params, args)

Creates a new infobox. Automatically parses the arguments, creates SMW subobjects and adds categories. 

	local infobox = Infobox.new(config, params, args)

config

There are only 3 parameters for config 

	local config = {
    	infobox_name = 'Scenery', -- mandatory unique identifier for css
        class = {'CustomClass', Infobox.smw_param('episode')} -- optional, defaults to {}. Adds css classes to infobox table: {'infobox-CustomClass', 'infobox-[default version parameter's value]'}
    	max_buttons = 6, -- optional, defaults to 6, max number of switch buttons before using a dropdown list instead
	}

params

A list of parameters to be processed by the Infobox module 

	local params = {
		{ name = <param>, func = <func>, ... },
		...
	}


key value
name parameter name as used in the Template
func A function in Module:Param Parse to validate and process the Template argument. You can also use a local function, but this is not recommended.

If func is a function, will call func(Infobox.raw_param(name)): 

	{name = <param>, func = <func>, ... },

If func is a table, it takes the following parameters: 

	{name = <param>, func = { name = <func>, params = <func_params>}, ... },
name function in Module:Param Parse
params a list of parameters to pass the the function, in the form of constants, or Infobox.raw_param(name), Infobox.param(name), Infobox.smw_param(name)
empty (optional) text to display in the infobox if func returns nil; defaults to "? (edit)"
category_never (optional) category to add if func returns nil for all versions
category_partial (optional) category to add if func returns nil for some versions, but a value for other versions
category_incomplete (optional) category to add if func returns nil for at least 1 version (i.e. category_never and category_partial combined)
category_complete (optional) category to add if func returns a value for all versions
smw_property (optional) if this string is defined, the parameter will be saved into SMW
smw_func (optional) function to validate and process the Template argument to save into SMW. func is used by default if smw_func is not defined

args

Arguments passed via the Template 

	local args = frame:getParent().args

infobox:is_param_defined(param)

Used to conditionally display a line in the infobox 

	infobox:add_row{
		{tag='th', content=Infobox.param('name'), class='infobox.subheader', colspan='2'},
	}
	if infobox:is_param_defined(Infobox.param('owner')) > 0 then
		infobox:add_row{
			{tag='td', content='[[Owner]]'},
			{tag='td', content=Infobox.param('owner')},
		}
	end
param a parameter referenced via Infobox.raw_param(name), Infobox.param(name) or Infobox.smw_param(name)
Returns 0 if param is never defined

1 if param is defined for a fraction of the versions

2 if param is defined for all versions

Infobox:add_row(...)

Adds a row to the infobox table. Parameter should be a table of cells: 

	infobox:add_row{
		{tag='td', content='[[Cell1]]', ...},
		{tag='td', content=Infobox.param('param'), ...},
		{tag='td', content='[[Cell3]]', ...},
        ...
        addClass = 'row-class'
	}

Each cell should have a set of key-values, of which only the tag and content are mandatory:

key value
tag 'td' or 'th'
content a string or Infobox.param(name), Infobox.raw_param(name), Infobox.smw_param(name)
attr (optional) a table of attributes to add to the cell

mw.html:attr({ arg1 = '1', ... })

css (optional) a table of css to add to the cell

mw.html:css({ arg1 = '1', ... })

class (optional) a string with a class to add, or a table of classes to add. infobox-header, infobox-subheader and infobox-image are commonly used.

mw.html:addClass(...)

rowspan (optional) Set the cell rowspan

mw.html:attr('rowspan',arg)

rowspan (optional) Set the cell colspan

mw.html:attr('colspan',arg)

title (optional) Set the cell title

mw.html:attr('title',arg)


Infobox:pad(colspan, class)

Adds a blank row of padding spanning the given number of columns. Will always add the class infobox-padding, but can optionally add another class: 

	infobox:pad("10", class=<class>)


Infobox:addClass(class)

Adds a class to the entire table 

	infobox:addClass(class)


Infobox:dump()

Logs all the values into the Debug console for debugging purposes. You can also dump all the values in an Infobox template by setting a template parameter "__dump = Yes".
