 | This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected. |
 | 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 Lua module is used on approximately 1,460,000 pages, or roughly 2% 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 own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk 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.
Usage
[edit]Basic usage
[edit]{{#invoke:Check for clobbered parameters|check |nested=1 |template=Some template name |cat={{main other|Category:Some tracking category}}|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.
