Module:Param Parse requires Module:Currency.
Module:Param Parse requires Module:Infobox.
Module:Param Parse is required by .

These params and functions are used to validate and format information passed into an Infobox. See Module:Infobox for details and instructions on creating an Infobox. If the information is missing or not valid, the functions here should return nil.

Here is a summary of all the params:

param explanation
parse.name Title
parse.examine Examine info
parse.image [[File:IMAGE.png]]. Use the class infobox-image in the table
parse.image_size300 [[File:IMAGE.png|300x300px]] by default unless overridden. Use the class infobox-image in the table
parse.episode Episode name
parse.premium Premium (Yes, No, N/A)
parse.release Release Date in the format YYYY-MM-DD
parse.value Shows the value as a denomination of coins
parse.profession TODO
parse.profession_bubble_a, parse.profession_bubble_b Takes parameters profession_a + profession_a_level, or profession_b + profession_b_level
parse.profession_a_smw, parse.profession_a_level_smw, parse.profession_b_smw, parse.profession_b_level_smw Exports the data from profession_bubble_a and profession_bubble_b to smw
parse.variant TODO - Which category the subject is a variant of
parse.passive Passiveness (Yes, No, N/A)

Here are some general use functions that can be used for custom or new params:

function name explanation
has_content(arg) Returns arg if any non-whitespace character is found in the string.
number(num) Removes any commas and parses the string as a number
yes_no(text) Only accepts "Yes", "No" and "N/A"
yes_no_smw(text) Maps "Yes", "No" to true and false respectively

Creating New Params

Ideally, params should be defined here so that they can be reused between different Infoboxes. Here is how to create a new param: 

parse.paramname = {
	name = <param>,
    func = <func>,
    empty = 'empty', -- optional
    category_never = 'category', -- optional
    category_partial = 'category', -- optional
    category_incomplete = 'category', -- optional
    category_complete = 'category', -- optional
    smw_property = 'Property', -- optional
    smw_func = <func>, -- optional
}


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
