Undid revision 1029073259 by Gonnym (talk) undo for now, as this breaks Template:Italic title transclusions that 1) have a dab, 2) use the "string" argument, and 3) don't use the "all" argument |

This Lua module is used on approximately 1,090,000 pages, or roughly 19768% 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 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 implements {{italic title}} and {{italic dab}}. Please see the template pages for documentation.
