Module:Anchor/sandbox
Appearance
![]() | This is the module sandbox page for Module:Anchor (diff). See also the companion subpage for test cases (run). |
![]() | This Lua module is used in system messages, and on approximately 87,000 pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
![]() | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
![]() | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
![]() | This module depends on the following other modules: |
This module implements {{anchor}}. Please see the Template:Anchor/doc page for documentation.
-- This module implements {{anchor}}.
local p = {}
function p.main(frame)
-- Faster method implemented by Luis150902
-- Step 1. Create a local variable to store the anchors,
-- initialised to the empty string.
local ret = ""
-- Step 2. Create a iterator variable, initialised to 1.
local i = 1
-- Step 3. While there exists a positional argument referenced by
-- the iterator variable, do the following:
while not (frame.args[i] == nil)
do
-- (a) Add a empty span whose id is the value of the argument
-- to the local variable storing the anchors;
ret = ret .. '<span id="' .. frame.args[i] .. '"></span>'
-- (b) Increment the iterator variable.
i = i + 1
end
-- Step 4. Return the value of the local variable storing the anchors.
return ret
