Module:DisplayFunctions

This module contains several display helper functions for the Module:InfoboxBuilder and Module:DatatableBuilder. The only dependency this module has is Module:List; this is required to use list(listType) and is only loaded when needed.

Functions

image

DisplayFunctions.image(imageSize)

Pass the desired image size as a parameter when setting it as the display function for a row. When called, this function will return a function that uses the first parameter as the filename.

link

DisplayFunctions.link

When called, this function will use the first parameter as the link.

list

DisplayFunctions.list(listType)

Pass the desired type of list as a parameter when setting it as the display function for a row. When called, this function will return a function that turns an array into a list.

Valid list types are:

• bulleted
• unbulleted
• horizontal
• ordered
• horizontal_ordered

Examples of these lists can be found on Wikipedia's documentation for Module:List.

trueFalseOther

DisplayFunctions.trueFalseOther(trueVal, falseVal, otherVal)

Pass the true value, false value, and value if other as parameters when setting it as the display function for a row. When called, this function will return a function that takes a boolean value and returns the corresponding true, false, or other value.

yesAndNo

DisplayFunctions.yesAndNo

When called, this function will display "Yes" for true, "No" for false, and nil for everything else. This is a special case of trueFalseOther(trueVal, falseVal, otherVal).

checkAndX

DisplayFunctions.checkAndX

When called, this function will display "✓" for true, "✗" for false, and nil for everything else. This is a special case of trueFalseOther(trueVal, falseVal, otherVal).

pluralHeader

DisplayFunctions.pluralHeader(forms)

Pass in a table of grammatical forms (see MediaWiki's documentation on the correct format) as the parameter when setting it as the display function for a row. When called, this function will return a function that selects the correct plurality based on the array passed in as parameter.

minutesAndSeconds

DisplayFunctions.minutesAndSeconds

When called, this function will format a number (assumed to be seconds) into the "m:ss" format.
