==Functions==
==Functions==
===Public functions===
=== Special params ===
You don't need to do anything about these special parameters, but they may be used as parameters within the Template:
For the example snippets below, <code>ret</code> is an arbitrary infobox initiated as:
<syntaxhighlight lang="lua">
local ret = Infobox.new(args)
</syntaxhighlight>

====Priority====
Certain functions rely on information created by other functions, and thus must be run in a particular order:

{| class="wikitable"
{| class="wikitable"
! 0
! param
! explanation
|
* new
|-
|-
| version1, version2, version3
! 1
| Button label and SMW name for each switch version of the infobox
|
* defineParams
|-
|-
| default_version
! 2
| The default version to display when the page is loaded
|
* create
* maxVersion
|-
|-
| version
! 3
| If there is only a single version, you can use version to set the SMW name (default SMW name is "DEFAULT")
|
|}
* cleanParams

* setMaxButtons
=== Referring to params ===
* noSwitch
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:
{| class="wikitable"
! helper function
! example
! explanation
|-
|-
| Infobox.raw_param(name)
! 4
| "1000"
|
| Raw value as passed by the Template
* ''other functions''
|-
|-
| Infobox.param(name)
! 5
| "1,000"
|
| Value formatted for display in the Infobox
* finish
|-
| Infobox.smw_param(name)
| 1000
| Value formatted to be saved as an SMW property
|}
|}


=== Infobox.new(config, params, args) ===
====nilParam====
Creates a new infobox. Automatically parses the arguments, creates SMW subobjects and adds categories.
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
local infobox = Infobox.new(config, params, args)
Infobox.nilParam()
</syntaxhighlight>
</syntaxhighlight>
==== config ====
Returns the value of the placeholder value <code>Infobox.nil_param</code>. This value is generally not seen, but it is used to fill switchbox data as <code>nil</code> causes unwanted behaviour.
There are only 3 parameters for config

====isDefined====
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
local config = {
Infobox.isDefined(arg)
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
}
</syntaxhighlight>
</syntaxhighlight>
Checks whether the value <code>arg</code> can be considered as [[Module:Infobox#Defined parameters|defined]].


====new====
==== params ====
A list of parameters to be processed by the Infobox module
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
local params = {
Infobox.new(args)
{ name = <param>, func = <func>, ... },
...
}
</syntaxhighlight>
</syntaxhighlight>
Creates a new infobox object with <code>args</code> as a <code>table</code> of values passed from the template invocation.


This function also creates the top-level wrapper and sets a metatable for the infobox.


{| class="wikitable"
====create====
! 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)):
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
{name = <param>, func = <func>, ... },
ret:create()
</syntaxhighlight>
</syntaxhighlight>
If func is a table, it takes the following parameters:
Creates the HTML tags used for the infobox itself. Will run <code>maxVersion()</code> if it has not been run already.

====defineName====
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
{name = <param>, func = { name = <func>, params = <func_params>}, ... },
ret:defineName(arg)
</syntaxhighlight>
</syntaxhighlight>
Defines the name of the infobox. This should be the base pagename; i.e. no "Template:" namespace prefix.

====setMaxButtons====
<syntaxhighlight lang="lua">
ret:setMaxButtons(n)
</syntaxhighlight>
Changes the behaviour of buttons by defining the maximum number of buttons that are allowed to appear. If the version count exceeds the button count, their buttons will be replaced with a drop down menu. If not run, the maximum button count will be 5.

====cleanParams====
<syntaxhighlight lang="lua">
ret:cleanParams()
</syntaxhighlight>
Parses the parameters with their mapped functions.

====defineParams====
<syntaxhighlight lang="lua">
ret:defineParams{
...
}
</syntaxhighlight>
Maps parameters to functions as defined by a <code>table</code> formatted as such:

<syntaxhighlight lang="lua">
{ name = <param>, func = <func>, dupes = true },
</syntaxhighlight>

<code>param</code> should be a <code>string</code> that names the parameter as it will be in references for use in other functions.

<code>func</code> should be a <code>function</code> or instructions on how to find a function.

<code>dupes</code> is a meta configuration that allows the parameter to be duplicated in switch data. Normally, these duplicate values are not needed, and they will be deleted if they are the same as the default values after all parameters have been parsed. Some parameters require duplication to function properly, such as display altering parameters defined with <code>linkParams()</code>.

If duplicates are not needed, this parameter should be deleted.

;Predefined functions
If <code>func</code> is a <code>string</code>, then the module will attempt to use a predefined function.

{| class="wikitable"
{| class="wikitable"
| name
! Function
| function in [[Module:Param Parse]]
! Use
|-
|-
| params
! <tt>name</tt>
| 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)
| Uses the parameter named "name". If "name" is blank or undefined, it will use the page name.
|}
|-
|-
| empty (optional)
! <tt>release</tt>
| text to display in the infobox if func returns nil; defaults to "? (edit)"
| Uses the parameters named "release" and "update" and formats it as such:
* If both are defined: <code><nowiki><release> ([[Update:<update>|Update]])</nowiki></code>
* If only release is defined: <code><release> (Update unknown)</code>
* If release is not defined: <code>? (edit)</code>
|-
|-
| category_never (optional)
! <tt>removal</tt>
| category to add if func returns nil for all versions
| Uses the parameters named "removal" and "removalupdate" and formats it the same as <code>release</code>
|-
|-
| category_partial (optional)
! <tt>hasContent</tt>
| category to add if func returns nil for some versions, but a value for other versions
| If the parameter is defined and not blank, it will be used. Otherwise, <code>? (edit)</code> will be used.
|-
|-
| category_incomplete (optional)
! <tt>image</tt>
| category to add if func returns nil for at least 1 version (i.e. category_never and category_partial combined)
| Currently functions the same as <code>hasContent</code>
|-
|-
| category_complete (optional)
! <tt>numbers</tt>
| category to add if func returns a value for all versions
| Removes commas from the parameter and attempts to cast it to a <code>number</code>. If it works, the number is used, otherwise <code>? (edit)</code>
|-
| 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 ====
;User-defined functions
Arguments passed via the Template
If <code>func</code> is a <code>function</code>, then that function will be used to parse the parameter. User-defined functions allow for more robust formatting and guidelines.

As a general practice, user-defined functions should be located under the <code>main</code> functions in the module. It is best to document these functions so that they may be changed by other editors if necessary.

In user-defined functions, circumstances where the edit button should be shown should return <code>nil</code>, which is automatically handled by the module.

;Simple and complex definitions
Parameters may be mapped to functions in a straightforward manner by simply definining a name of or reference to a function, such as:
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
local args = frame:getParent().args
ret:defineParams{
{ name = 'foo', func = 'hasContent' },
{ name = 'bar', func = barFunc }
}
</syntaxhighlight>
</syntaxhighlight>


=== infobox:is_param_defined(param) ===
Simple definitions only pass the parameter from the master list named <name>. Some parameters need more interaction with other parameters. To do this, we require a complex definition. Complex definitions point to a user-defined function and map what parameters to pass. Complex definitions can also pass literal values or the uncleaned value with the use of flags.
Used to conditionally display a line in the infobox


Complex functions are defined as <code>table</code> values formatted as such:
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
infobox:add_row{
func = { name = <funcname>, params = { <paramname>, ... }, flag = <flags> }
{tag='th', content=Infobox.param('name'), class='infobox.subheader', colspan='2'},
</syntaxhighlight>

A basic example for complex functions is:
<syntaxhighlight lang="lua">
ret:defineParams{
{ name = 'foo', func = { name = fooFunc, params = { 'bar', 'baz' } },
}
}
if infobox:is_param_defined(Infobox.param('owner')) > 0 then
-- ...
infobox:add_row{
-- ...
{tag='td', content='[[Owner]]'},
function fooFunc(arg1,arg2)
{tag='td', content=Infobox.param('owner')},
return arg1..arg2
}
end
end
</syntaxhighlight>
</syntaxhighlight>
{| class="wikitable"
| 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
In this example, we have a parameter named "foo", but we use the parameters passed to the template named "bar" and "baz". Parameters are passed in the order listed, so in the above, the parameter <code>bar</code> is used for <code>arg1</code>, and <code>baz</code> is used for <code>arg2</code>.
|}


=== Infobox:add_row(...) ===
Flags define the behaviour of the parameters named. The following flag behaviours exist:
Adds a row to the infobox table. Parameter should be a table of cells:
* <code>d</code> - Looks for the cleaned and parsed version of the parameter. If not cleaned, it will use the value passed to the template. If neither exist, it will use <code>nil</code>. This is the default behaviour if no flag is defined.
* <code>p</code> - Looks only at the value passed to the template. If it does not exist, it will use <code>nil</code>.
* <code>r</code> ''or'' <code>l</code> - Uses the literal (or raw) value.

If <code>flag</code> is a <code>string</code>, then the behaviour defined by it will apply to every parameter passed. If <code>flag</code> is a <code>table</code>, then each flag will only define the behaviour of the respective parameter.

For example:
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
infobox:add_row{
ret:defineParams{
{ name = 'foo', func = {
{tag='td', content='[[Cell1]]', ...},
{tag='td', content=Infobox.param('param'), ...},
name = fooFunc,
params = { 'foo', 'bar', 'baz' },
{tag='td', content='[[Cell3]]', ...},
...
flag = { 'd', 'p', 'l' },
addClass = 'row-class'
},
}
</syntaxhighlight>

In the above snippet, <code>foo</code> will use the default behaviour and <code>bar</code> will only look for the value passed to the template. The third parameter will use the string literal <code>'baz'</code>.

;Definition order
Parameters are defined in the order that they are coded. If a parameter relies on the cleaned value of another parameter, then the parameter dependent on the other will need to be defined after in the definition table.

====addRow====
<syntaxhighlight lang="lua">
ret:addRow(tbl)
</syntaxhighlight>
Adds a new row to the template with columns and behaviour defined by <code>tbl</code>, which should be a <code>table</code> that holds cells defined as <code>table</code> variables, formatted as such:

<syntaxhighlight lang="lua">
{
{ celltype, label, <attr1> = <value1>, <attr2> = <value2> ... },
...
}
}
</syntaxhighlight>
</syntaxhighlight>
Each cell should have a set of key-values, of which only the tag and content are mandatory:

<code>celltype</code> and <code>label</code> are <code>string</code> values that define the fundamental display of the cell.

{| class="wikitable"
{| class="wikitable"
! key
! <tt>celltype</tt>
! Output
! value
|-
|-
| tag
! <tt>th</tt>
| 'td' or 'th'
| Creates a <code><nowiki><th></nowiki></code> tag where the content is the value of <code>label</code>
|-
|-
| content
! <tt>td</tt>
| a string or Infobox.param(name), Infobox.raw_param(name), Infobox.smw_param(name)
| Creates a <code><nowiki><td></nowiki></code> tag where the content is the value of <code>label</code>
|-
|-
| attr (optional)
! <tt>argh</tt>
| a table of attributes to add to the cell
| Creates a <code><nowiki><th></nowiki></code> tag where the content is the value of the parameter named <code>label</code>
mw.html:attr({ arg1 = '1', ... })
|-
|-
| css (optional)
! <tt>argd</tt>
| a table of css to add to the cell
| Creates a <code><nowiki><td></nowiki></code> tag where the content is the value of the parameter named <code>label</code>
mw.html:css({ arg1 = '1', ... })
|}

The attributes are any of the available attributes defined inside the function. All functions that are ultimately run are documented in the [[mw:Extension:Scribunto/Lua reference manual#HTML library|Lua reference manual]] and are run on the tag for the specific table cell they are called on.

{| class="wikitable"
! <tt>attr</tt>
! Type
! Use
|-
|-
| class (optional)
! <tt>attr</tt>
| a string with a class to add, or a table of classes to add. '''infobox-header''', '''infobox-subheader''' and '''infobox-image''' are commonly used.
| <tt>table</tt>
mw.html:addClass(...)
| Passes the value to <tt>mw.html.attr()</tt>
|-
|-
| rowspan (optional)
! <tt>css</tt>
| Set the cell rowspan
| <tt>table</tt>
mw.html:attr('rowspan',arg)
| Passes the value to <tt>mw.html.css()</tt>
|-
|-
| rowspan (optional)
! <tt>colspan</tt>
| Set the cell colspan
| <tt>number</tt>
| Uses the value to run <tt>mw.html.attr('colspan',#)</tt>
mw.html:attr('colspan',arg)
|-
|-
| title (optional)
! <tt>rowspan</tt>
| Set the cell title
| <tt>number</tt>
| Uses the value to run <tt>mw.html.attr('rowspan',#)</tt>
mw.html:attr('title',arg)
|-
! <tt>title</tt>
| <tt>string</tt>
| Uses the value to run <tt>mw.html.attr('title',text)</tt>
|-
! <tt>class</tt>
| <tt>string</tt>
| Passes the value to <tt>mw.html.addClass()</tt>
|-
! <tt>class</tt>
| <tt>table</tt>
| Passes every value in the table to <tt>mw.html.addClass()</tt>
|}
|}


If the template is a switch infobox, then <code>data-attr-param="<paramname>"</code> will be added to the table cell.


=== Infobox:pad(colspan, class) ===
This function will return the template, allowing further self functions to be performed.
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:

====wikitext====
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
infobox:pad("10", class=<class>)
ret:wikitext(txt)
</syntaxhighlight>
</syntaxhighlight>
Appends wikitext to the top-level wrapper. Templates, etc. passed directly from Lua code will need explicit preprocessing prior to display properly.


This function will return the template, allowing further self functions to be performed.


=== Infobox:addClass(class) ===
====caption====
Adds a class to the entire table
<syntaxhighlight lang="lua">
<syntaxhighlight lang="lua">
infobox:addClass(class)
ret:caption()
</syntaxhighlight>
</syntaxhighlight>
Adds a caption to the infobox based off the subject name, using the following priority for the text:
* <code>name</code> parameter
* <code>name1</code> parameter (if switch infobox)
* <code><nowiki>{{PAGENAME}}</nowiki></code>

If the template is a switch infobox, this will also add <code>data-attr-param="name"</code> to the <code>caption</code>.

This function will return the template, allowing further self functions to be performed.

====attr====
<syntaxhighlight lang="lua">
ret:attr(arg)
</syntaxhighlight>
Passes <code>arg</code> to <code>mw.html.attr()</code>.

This function will return the template, allowing further self functions to be performed.

====float====
<syntaxhighlight lang="lua">
ret:float(dir)
</syntaxhighlight>
Changes the direction of the CSS style <code>float</code> for the top level wrapper. By default, all infoboxes float <code>right</code>.

This function will return the template, allowing further self functions to be performed.

====css====
<syntaxhighlight lang="lua">
ret:css(...)
</syntaxhighlight>
Passes the arguments to <code>mw.html.css()</code>.

This function will return the template, allowing further self functions to be performed.

====addClass====
<syntaxhighlight lang="lua">
ret:addClass(arg)
</syntaxhighlight>
Passes <code>arg</code> to <code>mw.html.addClass()</code>.

This function will return the template, allowing further self functions to be performed.

====addClasses====
<syntaxhighlight lang="lua">
ret:attr(...)
</syntaxhighlight>
Passes every argument to <code>mw.html.addClass()</code> individually.

This function will return the template, allowing further self functions to be performed.

====tag====
<syntaxhighlight lang="lua">
ret:tag(arg)
</syntaxhighlight>
Passes <code>arg</code> to <code>mw.html.tag()</code>.

This function will return the tag (not the template), allowing further self functions to be performed.

====useSMW====
<syntaxhighlight lang="lua">
ret:useSMW(tbl)
</syntaxhighlight>
Tells the module to create properties for parameters, as well as defining those mappings with <code>tbl</code>, a <code>table</code> whose elements form an associated array formatted as such:

<syntaxhighlight lang="lua">
{
parameter = property,
...
}
</syntaxhighlight>

When defined, properties will be defined for two separate properties: both "Property:<name>" and "Property:All <name>". If the template holds switch infobox data, then properties will be defined for "Property:<name><X>" for all applicable X. The "All <name>" properties exist to create storage for all applicable values. Keep this in mind, as "Property:<name>" will only ever store the default value.

By default, the module will define [[Property:Release date]] and [[Property:Is members only]].

====noSwitch====
<syntaxhighlight lang="lua">
ret:noSwitch()
</syntaxhighlight>
Forces the template to use only a single version, the default.

====maxVersion====
<syntaxhighlight lang="lua">
ret:maxVersion()
</syntaxhighlight>
Returns the number of versions used by the infobox. When run the first time, this function will check and define the version count first. Subsequent calls will simply return the count.

====linkParams====
<syntaxhighlight lang="lua">
ret:linkParams{
paramName = linkedParam,
...
}
</syntaxhighlight>
Links two parameters where one parameter (<code>paramName</code>) is the parameter name of a cell's contents, and <code>linkedParam</code> is the name of the parameter that contains the classes for the specified cell. It will only have an effect on switch infoboxes. Both parameters will need to be defined in the infobox with <code>definedParams</code>. They should be functions of the parameter they operator on and include <code>dupes = true</code> in their definitions.

This function must be called only '''after''' calling <code>ret:cleanParams()</code> (and before <code>ret:finish()</code>).

Example: grand exchange graphs do not make sense to display for untradeable items within switch infoboxes (e.g. [[ahrim's staff]]); one could use a linkParam to add a class that will display:none table row when switching to untradeable items.

In the source code of the infobox, these will be added as such:

<syntaxhighlight lang="html5">
<div class="infobox-switch-resources hidden">
<span data-attr-param="param">
<span data-attr-index="0" data-addclass="linkedParam[d]">paramName[d]</span>
<span data-attr-index="1" data-addclass="linkedParam[1]">paramName[1]</span>
<span data-attr-index="2" data-addclass="linkedParam[2]">paramName[2]</span>
</span>
</div>
</syntaxhighlight>

From this, the switch infobox javascript will add the contents of <code>data-addclass</code> to class attribute of the row of the table when the infobox is switched. You will also need to define the classes you are using in global CSS.

If the parameter is a th or td element, the class is added to the parent tr. Otherwise, it is added to the element directly (e.g. caption element).

====finish====
Finalises the template and adds remaining required HTML.

* Creates hidden tag for switch infobox data (if needed)
* Adds [[:Category:Pages that contain switch infobox data]] if in the mainspace
* Defines [[Property:Version count]] if in the mainspace
* Adds [[RS:SMW|Semantic MediaWiki Data]] in a hidden tag (if needed)
*: This data can be viewed on the page itself by using inspect element, but it is not normally visible
* Adds infobox bottom links

====param====
<syntaxhighlight lang="lua">
ret:param(arg, flag)
</syntaxhighlight>
Returns the value of the parameter named <code>arg</code>. The exact format and values are determined by the <code>flag</code>:

* <code>d</code> ''or'' empty - default value of the parameter
* <code>f</code> ''or'' <code>full</code> - all values of the parameter as a table
* <code>s</code> ''or'' <code>switches</code> - table of all switch values (or nil if no switches are present)
* <code>s#</code> - switch value at index <code>#</code>
* <code>r</code> - if defined, switch value 1, otherwise the default value

Note that this function returns the actual table used by the template. If a switch value is equal to <code>Infobox.nil_param</code> for flag <code>s#</code>, then <code>nil</code> will be returned instead; however, when calling specific indices from the tables returned by <code>f</code> or <code>r</code>, the value of <code>Infobox.nil_param</code> will be returned without extra parsing.

====paramDefined====
<syntaxhighlight lang="lua">
ret:paramDefined(arg, flag)
</syntaxhighlight>
Looks to see if the parameter named <code>arg</code> is [[Module:Infobox#Defined parameters|defined]] at any index, based on instructions from <code>flag</code>:

* <code>0</code> ''or'' empty - default value of parameter
* <code>#</code> - value of switch at index <code>#</code>
* <code>all</code> - true if the parameter is defined with a default or at any switch value

====paramGrep====
<syntaxhighlight lang="lua">
ret:paramGrep(arg, query)
</syntaxhighlight>
Performs a function or search on every possible value of the parameter named <code>arg</code>. <code>query</code> can be either a <code>function</code>, a <code>string</code>, or a <code>number</code>. If a match is found or the function query returns true, <code>paramGrep</code> will end its search.

If <code>query</code> is a function, that function must pass a single argument (the parameter), and return either <code>true</code> or <code>false</code>.

If <code>query</code> is a string, then that string will be compared to each value of the parameter. If they match exactly, disregarding casing, then <code>true</code> will be returned. To perform a pattern match on strings, you will need to define <code>query</code> as a function that returns a boolean value based on <code>string.find</code> or <code>mw.ustring.find</code>.

If <code>query</code> is a number (or any other type), then it will be compared to each value for a match.

Matches are only checked if the type of <code>query</code> matches the value of the parameter; e.g., it is not valid to search for a number (ex: <code>4</code>) inside a string (ex: <code>'455'</code>).

====paramRead====
<syntaxhighlight lang="lua">
Infobox.paramRead(arg, query)
</syntaxhighlight>
Performs the same function as <code>paramGrep</code>; however, instead of <code>arg</code> being a name of a parameter to look for, it is the table itself. Useful for functions where only the table of parameters is passed, but not the whole infobox.

====categoryData====
<syntaxhighlight lang="lua">
ret:categoryData()
</syntaxhighlight>
Returns fundamental category data collected during <code>Infobox:cleanParams()</code>.

Fields in the category data include:
* <code>one_defined</code> - <code>true</code> if at least one possible value of the parameter is defined
* <code>all_defined</code> - <code>false</code> if at least one possible value of the parameter is not defined

====addDropLevelVars====
<syntaxhighlight lang="lua">
Infobox:addDropLevelVars(key, paramName)
</syntaxhighlight>
Used to link infobox versions to specific [[Template:DropsLine|drops table]] versions. Sets a var <code>DropLevel_{key}_{version_name}</code>, where the value is pulled from the value of the given param <code>paramName</code> at each version. If multiple values are set with the same key, the result will be a comma separated string.

For example, if an infobox has <code>|version1 = A|level1 = 10</code>, then <code>ret:addDropLevelVars('combat', 'level')</code> will set the variable <code>DropLevel_combat_A = 10</code>.


==Rules==
===Defined parameters===
Parameters are to be considered "defined" if they meet all of the following criteria:


=== Infobox:dump() ===
* Is not <code>nil</code>
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".
* Contains at least one non-whitespace character <code>string.find(param,'%S')</code>
* Is not equal to <code>Infobox.nil_param</code>
* Does not contain the string <code>'action=edit'</code>

This is a documentation subpage for Module:Infobox.
It contains usage information, categories, and other content that is not part of the original module page.
Module:Infobox requires Module:Edit button.
Module:Infobox requires Module:SMW Utils.

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

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 = 'examine', func = parse.has_content, smw_property = 'Examine'}, -- Custom param
        parse.episode,
 		...
	}

Define an Infobox object

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

Create your table

	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='Examine', colspan="6"},
			{tag='td', content=Infobox.param('examine'), 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".
