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

Usage

CautionThis module is invoked by {{NUMBEROFSECTIONS}}
sections
{{ #invoke:NUMBEROFSECTIONS|main| page name ] | level = section level number(s) }}
  1. Multiple page names (at least one required) are the # delimited names of any Misplaced Pages pages (including namespaces).
  2. section level(s) (required) is any group of numerals between 1 and 6 (inclusive) e.g. 435 or 5 3 4 equates to:
sections with a level 3 ( "===" ), 4 ( "====" ) or 5 ( "=====" ) heading.
{{#invoke:NUMBEROFSECTIONS|main|Misplaced Pages:Village pump (technical)|level=2}} produces Script error: The function "main" does not exist.
{{#invoke:NUMBEROFSECTIONS|main|Misplaced Pages:Village pump (technical)#Misplaced Pages:Village pump (proposals)|level=2}} produces Script error: The function "main" does not exist.
The above documentation is transcluded from Module:NUMBEROFSECTIONS/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (create) pages.
