The EditSubpages extension restricts anonymous users from editing most pages. Sysops (or whatever group has the 'editinterface' permission) can add pages to "MediaWiki:Unlockedpages" to allow anonymous editing.

Usage

Add pages to be unlocked to MediaWiki:Unlockedpages in a bulleted list (they may be links). Any line that isn't part of a bulleted list is treated as a comment. Example:

* Unlocked page 1
# Comment. Note that declaring the namespace matters
* Help:Unlocked page 2
* Talk:Unlocked page 3
 This is a comment too :). Unlike page 1, which has both the
 subject and talk page unlocked, page 3 only has an unlocked
 talk page.
* Unlocked page 4/subpage
# this will only unlock subpages of this subpage, so page 4 itself
# uneditable by anons.

This will allow anonymous users (or any user lacking the 'edit' permission) to edit that page and all subpages of it (e.g. Unlocked page 1, Unlocked page 1/Subpage, etc.), as well as their respective talk pages. If you declare a talk page, it will not make the respective subject page editable. To prevent talk pages from being edited but allow the subject pages to be, simply protect the talk page.

This will also allow the anonymous users to create new pages that are sub-pages of the unlocked page.

Extended syntax

The extended syntax (also known as flags), allows you to control exactly how each unlocked page works. The way of utilizing this is as follows:

* Unlocked page|flags|alternate text (optional, useful if you are using links)
# ex:
* [[Somepage/sub/subpage|+b-t|unlocks base pages but does not unlock talk pages]]
* HELLO|+in-c
# The above unlocks HELLO, Hello, Help:Hello, User:HEllO, etc.
# but does not allow creation of new pages

List of flags (* = enabled by default)

Flag	Description	Flag	Description
+s*	Unlocks subpages of the page	-s	Does not unlock subpages of the page
+b	Unlocks basepages of the page	-b*	Does not unlock basepages of the page
+u	Apply these restrictions to both users and anons	-u*	Only apply these restrictions to anons
+c*	Allow creation of new pages	-c	Do not allow creation of new pages
+t*	Unlock the talk page as well	-t	Do not unlock the talk page as well
+e*	Allow editing of unlocked pages	-e	do not allow editing of unlocked pages
+i	Case insensitive	-i*	case sensitive
+n	Namespace inspecific	-n*	Namespace specific
+r	Treated as a regex fragment	-r*	Treated as a string
+w	Allow wildcards * and ?	-w*	Does not allow wildcards
+w does not work with +r set. * means "0 or more characters", ? means "0 or 1 characters" Character classes are denoted with square brackets, such as [ae] to match a or e Negate a character class with !, e.g. [!ae] to match everything except a or e Literal *, ?, [, and ] must be escaped with \ (like \* and \?. \\ produces a literal backslash)

Caveats

• This extension goes down the list in order and stops when it reaches the first match. As such, it is impossible to have multiple conditions for a single page/group of pages.
• The +r flag has an implicit ^ and $ before and after the fragment, respectively. This means if you want it only to match part of a title, you will need to use ".*title.*" and not just "title." (Former parses to /^.*title.*$/, latter to /^title$/)
• The extension's require_once either needs to be after you configure $wgGroupPermissions on your LocalSettings.php file, or you need to make sure that '*' is allowed to 'edit', 'createpage', and 'createtalk', or the extension will not work as expected.
• The +u flag applies to all logged-in users, no matter what groups they are in (aka sysops are not exempt). As such, it is possible to lock yourself out of the list of unlocked pages until you disable the extension.

Installation

• Download and move the extracted EditSubpages folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/EditSubpages
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'EditSubpages' );
  

• Configure at your convenience
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

As of version 3.1, it is possible to modify what the default flags are via $wgEditSubpagesDefaultFlags. This can either be a string in the format +blah-blah, like MediaWiki:Unlockedpages, or in an array format where flags are the keys and the value is true if it should be set by default, and false if it should be unset by default.
