 | Note: This module is used on a lot of pages. In order not to put too much load on the servers, edits should be kept to a bare minimum. Please discuss proposed changes on the talk page first.
- Editing a module causes all pages that use the module to be re-rendered. If the module is used often, this can put a lot of load on the servers since it fills up the job queue.
- Keep in mind that displays produced by modules used on file description pages also show up on other wikis.

This message box is using an invalid "type=query" parameter and needs fixing.
 | This module is rated as ready for general use. It has reached a mature form and is thought to be bug-free and ready for use wherever appropriate. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
This module causes an error if any nil global is read or if any global is written to, with the exception of arg. To use, add require('Module:No globals') to the top of the module using it. The arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
local mt = getmetatable(_G) or {}
function mt.__index (t, k)
if k ~= 'arg' then
-- perf optimization here and below: do not load Module:TNT unless there is an error
error(require('Module:TNT').format('I18n/No globals', 'err-read', tostring(k)), 2)
end
return nil
end
function mt.__newindex(t, k, v)
if k ~= 'arg' then
error(require('Module:TNT').format('I18n/No globals', 'err-write', tostring(k)), 2)
end
rawset(t, k, v)
end
setmetatable(_G, mt)
