Module:LowercaseFirstLetter

Module documentation[view] [edit] [history] [purge]

A heuristic to return the current page name with the initial character lower cased, but only if all other character are in lower case. Otherwise, the name is returned as-is. This behaviour is useful because Wikipedia is configured to uppercase that first letter. See technical restrictions. This heuristic is fallible, so other methods are required for accuracy.

For example, the first use of this module was by {{R from domain name}}, and their parameter |lowercase=yes/no/module (with module being the default) controlled for accuracy. This default simply meant to use this module.
