 | Thismodule is rated asready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned onhelp pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed throughsandbox testing rather than repeated trial-and-error editing. |
 | This module is currentlyprotected from editing. See theprotection policy andprotection log for more details. Please discuss any changes on thetalk page; you maysubmit an edit request to ask anadministrator to make an edit if it isuncontroversial or supported byconsensus. You may alsorequest that this page be unprotected. |
 | This Lua module is used onapproximately 4,690,000 pages, or roughly 7% of all pages. To avoid major disruption and server load, any changes should be tested in the module's/sandbox or/testcases subpages, or in your ownmodule sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on thetalk page before implementing them. |
 | This module depends on the following other modules: |
This module may be appended to a template to check for uses of tuples of conflicting parameters.
{{#invoke:Check for conflicting parameters|check|nested=1|template=Some template name|cat={{main other|Category:Pages using TEMPLATENAME with conflicting parameters}}|arg1a; arg1b|arg2a; arg2b; arg2c|...|argNa; argNb}}
Here, (arg1a,arg1b), (arg2a,arg2b,arg2c), are tuples of the conflicting parameters.
By default, the module ignores blank parameters which is useful for{{if empty}} chains of parameters. For nested chains of parameters, use|nested=1 to consider blank parameters as well.
By default, the delimiter for the tuples is; but this can be changed with|delimiter=.
The value of|template= is used to for the text of the preview warning message. When omitted, the module will use a generic message.
