Module:Static/doc

[refresh]

This is the documentation page. It is transcluded into Module:Static. See Template:Documentation for more information.

Usage

This module returns a table that can store data that persists in between multiple {{#Invoke:}} calls.

Example:

local p = {}

function p.main()
    local static = require( 'Module:Static' )
    static.x = ( static.x or 0 ) + 1
    return static.x
end

return p

If the above code sample was stored in Module:foo and then {{#Invoke:foo|main}} {{#Invoke:foo|main}} would result in 1 2.

Dev spec

Because data stored through this module can be invoked by any modules used in the same page. To avoid being interfered with by other modules, a module MUST store data in their own namespace. For example in "Module:Example":

...
    local static = require( 'Module:Static' )
    if not static.Example then
        static.Example = {}
    end
    static.Example.exampleData = 3
...

Data stored by a module, must be stored in a sub-table with the same name of that module (capitalize the first letter, and all spaces replaced with underscores). This sub-table should being initialized immediately after the invocation of this module.
