Manual talk:Configuration settings

Some archived discussion from when the page was located on meta can be found in /archive from meta (including full page history).

Let's kill the insane contents of this page!
I don't understand what value this page adds.


 * Category:MediaWiki configuration settings and other categories automatically list every variable.
 * The generated documentation should be the canonical source of the config variable descriptions.
 * (BTW, I'm not sure why Modules > Global settings in the generated doc is empty.)

So, why are we manually maintaining yet another way to get lost in 900+ configuration variables?

Note that MediaWiki is moving away from globals (T11968): I'll be returning to this issue as part of a future reorganizing and deprecating. I'd be happy if someone else is brave and kills 1000 lines of this before me :-)
 * Extensions specify SomeName settings in  extension.json that update configuration variables (see Manual:Extension registration).
 * Code should query ->config->get( ' Somename ) (see Manual:Configuration for developers).
 * That leaves just LocalSettings.php still screwing with  variables.

 * I use this page on a daily basis as part of providing support to Project:Support desk or IRC, whenever I have to check a variable name that I don't know if I'm spelling it right or I don't remember exactly the name. Categories are hard to navigate, while having all variables on one page and a small description is very valuable when performing searches on the page from the browser itself. --Ciencia Al Poder (talk) 09:42, 23 September 2015 (UTC)


 * While MW is moving away, it hasn't moved, so the documentation is still required.
 * The category listing(s), although listy, offer little to no information; they're just lists of links which all require following to be of any value.
 * Having a tidy single online source of basic info about related variables makes life easy for folk looking for info IMO.
 * What harm does it do to maintain this documentation while it's still relevant? I'd be the first to suggest killing archiving it when it's redundant. fredgandt 09:45, 7 March 2016 (UTC)

Undocumented globals
I went through a quick check through the default settings by looking for  MW version marks while comparing through the existing categories, these were the ones that came up to the list. I was going to originally make a personal todo subpage, but I figured it'd be more discoverable if it's on here. This list is probably incomplete, but I'll keep looking. Feel free to create any of these pages if you want to :)
