Module:OutputBuffer/doc

This is a documentation subpage for Module:OutputBuffer.
It may contain usage information, categories and other content that is not part of the original module page.

This module provides an easy and efficient way to generate lengthy strings.

Usage

First, load the module.

local newBuffer = require('Module:OutputBuffer')

Then, create the buffer and the functions that act on it.

local getBuffer, print, printf = newBuffer()

getBuffer

local text = getBuffer(sep)

Returns the contents of the buffer, with an optional separator string sep.

print

print(s)

Adds the string s to the buffer.

printf

printf(s, ...)

Adds the string s to the buffer. The string is formatted with any subsequent arguments, following the rules used for string.format.

Example

local newBuffer = require('Module:OutputBuffer')
local p = {}

function p.main()
	local getBuffer, print, printf = newBuffer()
	print('Welcome to the English Wikipedia.')
	printf('There are currently %d articles on this site.', mw.site.stats.articles)
	return getBuffer(' ')
end

return p

-- Assuming this module's name is "TestModule", and that mw.site.stats.articles returns 4500000,
-- {{#invoke:TestModule|main}} would output:
-- "Welcome to the English Wikipedia. There are currently 4500000 articles on this site."
