Module:InfoboxBuilder

This module creates an infobox using the builder pattern. All infoboxes using this module can be found at Category:Infobox modules.

Building an infobox

For an infobox to be built without errors, certain essential functions must be called before others. The following table details groups of functions and their priorities. The lower the number, the higher the priority. The functions setHeaderTextColor() and setHeaderBackgroundColor() are not required, but their CSS changes will not be applied if called later. In addition, the functions that add rows to the table, addHeader(), addImage(), and addRow() are not all required, but is it recommended to use at least addHeader() and addRow().

Core function priority

Priority	Functions
1	new
2	setParams setArgs
3	processArgs
4	setHeaderTextColor setHeaderBackgroundColor
5	setName addHeader addImage addRow
6	tostring

Import the module

local InfoboxBuilder = require('Module:InfoboxBuilder')

Unpack the frame arguments

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

Create the infobox object

local infobox = InfoboxBuilder.new()

Set the infobox name

Setting the infobox name sets the template that the infobox links to inside of the navbar.

infobox:setName('Infobox')

Define the parameters

When defining the parameters, the arguments will be processed when given a function or table. fn is an optional processing function or table that will transform the raw argument value into a specific format. An optional default value for the raw argument can be set using the default option.

An example of using fn would be to have fn be a function that splits a comma separated list into a table in Lua.

infobox:setParams {
	...
}

Pass in the arguments

infobox:setArgs(args)

Process the arguments

Processing the arguments will set default value (if it exists) and turn the raw argument passed in from setArgs(args) into a processed format for each parameter. This step is required or else the infobox will not work.

infobox:processArgs()

Specify a category map

A category map can be optionally set. This uses the processed argument and generates the correct categories.

infobox:setCategoryMap({
	...
})

Prepare

Create the look of the infobox by adding headers, images, or rows. If the values shown in these cells use values from parameters, an optional postprocessing function or table fn will transform the processed arguments for display purposes.

-- add a header or subheader
infobox:addHeader(
	{...},
	{...}
)

-- add an image
infobox:addImage(
	{...},
	{...}
)

-- add a row
infobox:addRow(
	{...},
	{...}
)

Build

To build the infobox from data into an HTML table, call the tostring() function.

infobox:tostring()

Get the categories from the category map

To get the categories, call the getCategories() function.

infobox:getCategories()

Functions

For the following functions, assume an InfoboxBuilder object called "infobox" already exists.

local infobox = InfoboxBuilder.new()

Public functions

new

This function is required.

InfoboxBuilder.new()

Creates a new InfoboxBuilder object.

↓ Jump to definition

setName

This function is required.
This function is chainable.

infobox:setName(arg)

arg

arg should be a string. Setting the infobox name will link the navbar to the correct template page and template talk page.

↓ Jump to definition

setHeaderTextColor

This function is optional.
This function is chainable.

infobox:setHeaderTextColor(arg)

arg

arg should be a string that contains a valid CSS color (hex code, rgb value, hsl value, etc.). Calling this function will change the color of the text in the infobox's headers and subheaders. The changes will not apply to headers added before this function is called, so it is recommended to call this function early.

↓ Jump to definition

setHeaderBackgroundColor

This function is optional.
This function is chainable.

infobox:setHeaderBackgroundColor(arg)

arg

arg should be a string that contains a valid CSS color (hex code, rgb value, hsl value, etc.). Calling this function will change the background color of the infobox's headers and subheaders. The changes will not apply to headers added before this function is called, so it is recommended to call this function early.

↓ Jump to definition

This function is required.
This function is chainable.

infobox:setParams(...)

This function sets the valid parameters, their default values, and their formatting.

The arguments passed in should be tables of format:

	fn = <processingFn>,
	default = <default>
}

paramName

paramName should be a valid string that is unique. This name serves the key used to grab the raw values from the args table passed in from setArgs(). It also serves as the key for each parameter and will be referenced later.

A collection of predefined processing functions can be found at Module:ProcessingFunctions.

default

default should be a string that serves as the default value if no raw value is present for the key in the args table. This value is optional.

↓ Jump to definition

setArgs

This function is required.

↓ Jump to definition

getArgs

infobox:getArgs(which)

which

which should be a string that is either "raw" or "processed" for the raw argument values or processed argument values, respectively.
