[00:00:36] <metalhead33>	 It looks like what I'm trying to achieve might be impossible.
[00:00:58] <metalhead33>	 Because it requires me to do plain HTML, and it doesn't seem like I can do it from a parser hook.
[00:01:06] <metalhead33>	 Because the WebGL needs a canvas.
[00:02:12] <metalhead33>	 https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Getting_started_with_WebGL
[00:26:06] <metalhead33>	 https://hastebin.com/ucanacozod.xml so far....
[00:47:49] <Skizzerz>	 metalhead33: tag extensions let you emit raw HTML
[00:48:23] <metalhead33>	 nice
[00:48:32] <metalhead33>	 Including javascript?
[00:48:48] <Skizzerz>	 it's recommended to make use of ResourceLoader modules if you need to add css or js to a page
[00:48:57] <metalhead33>	 Anyway, I have another question: can I programmatically parse a whole article (plaintext) in PHP? Or at least its url?
[00:49:00] <Skizzerz>	 your extension could set whether or not the module is loaded on any given page
[00:49:20] <metalhead33>	 Because I need to parse the shader from a named article.
[00:49:42] <Reedy>	 You can get the content of an arbitary page if you want
[00:49:45] <metalhead33>	  I am already using wfFindFile to find the files.
[00:49:45] <Reedy>	 And optionally parse it
[00:49:51] <metalhead33>	 Okay, but how? And in PHP?
[00:50:00] <metalhead33>	 I need the name of the function.
[00:50:02] <Reedy>	 Considering MediaWiki is written in PHP.. Yes in PHP
[00:50:17] <metalhead33>	 What is the function called?
[00:50:43] <metalhead33>	 Because I already found wfFindFile, but nothing similar for parsing a whole article.
[00:50:56] <Reedy>	 You'd want a WikiPage instance (probably), and then getContent()
[00:51:17] <Reedy>	 Global functions are mostly utility functions for ease
[00:51:42] <metalhead33>	 WikiPage::factory( $pageTitle ) ?
[00:53:12] <Skizzerz>	 it takes a Title object
[00:53:21] <metalhead33>	 Wut? Not a string?
[00:53:30] <Skizzerz>	 no
[00:53:34] <metalhead33>	 ugh....
[00:53:39] <metalhead33>	 I need something that takes a title string.
[00:53:42] <Skizzerz>	 Title::newFromText( $pageNameAsString )
[00:53:47] <metalhead33>	 thanks
[00:53:49] <Skizzerz>	 then pass that into WikiPage
[00:56:38] <metalhead33>	 https://hastebin.com/xefiwowice.php like this?
[00:57:23] <Skizzerz>	 that is invalid PHP
[00:57:27] <Skizzerz>	 -> is used for member access, not .
[00:57:41] <metalhead33>	 oh right, sorry.
[00:58:18] <Skizzerz>	 for a real extension you'd likely want to verify if Title::newFromText returns null or not (to indicate an invalid title) or if the page actually exists before trying to pull its content
[00:58:44] <Skizzerz>	 and your $output construction is vulnerable to XSS, never pass user input directly into HTML
[00:59:08] <Skizzerz>	 mediawiki has helper classes to construct HTML tags with proper escaping of user input
[00:59:09] <metalhead33>	 To be fair, I'm not even sure if my output construction is even valid to begin with
[00:59:38] <metalhead33>	 And I'm not even sure how will I invoke the WebGL Javascript thingie.
[00:59:49] <Skizzerz>	 I believe it's the Xml::* family of functions, but been a while since I've checked so that might've been deprecated and replaced with something else
[00:59:59] <metalhead33>	 Am I forced to write Javascript into module files, or can I just embed it into the PHP file?
[01:00:20] <metalhead33>	 You know, with <script type="text/javascript">
[01:00:41] <Skizzerz>	 you can, but it's not a good idea. Content-Security-Policy settings may block it from being loaded
[01:01:12] <metalhead33>	 Oh.... damn.
[01:01:21] <metalhead33>	 How else can I parse PHP arguments then?
[01:02:01] <Skizzerz>	 not sure what you mean by that
[01:02:15] <Skizzerz>	 (also I have to head off for the time being, I'll be back later)
[01:02:33] <Skizzerz>	 my best advice is "take a look at some other extensions that do similar things to what you're trying to do, and see how they do them"
[01:02:42] <metalhead33>	 How will the Javascript module make use of $model, for example?
[01:02:50] <metalhead33>	 Or $VertexShader?
[01:03:02] <metalhead33>	 The variables I defined in the PHP function so far.
[01:03:09] <metalhead33>	 (defined, but didn't return)
[01:04:59] <metalhead33>	 Something like adding <script>webglThing($param1, $param2, ...)</script>?
[01:08:34] <Reedy>	 There is addJsConfigVars on OutputPage
[01:08:37] <Reedy>	 Which you can pass stuff
[01:08:58] <metalhead33>	 Nice
[01:13:38] <metalhead33>	 Wait.... I intend to have multiple canvases per article though. Is that wise that way?
[01:19:06] <metalhead33>	 If I know that I will be calling the same parser hook multiple times, and it hooks into some Javascript stuff (because WebGL)....
[01:31:52] <metalhead33>	 Well anyway, time for me to sleep, gonna come back tomorrow morning.
[11:03:53] <jubo2>	 Thanks you for the uptime.
[11:59:40] <require_once>	 hello. trying to recover my mediawiki from an imaged drive (no proper mediawiki backup as mentioned in: https://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki) I basically installed everything from scratch and moved data from the image. i get this: https://controlc.com/d5b91624
[12:00:07] <require_once>	 by moved i mean copy&paste
[12:25:33] <harmaahylje>	 require_once: what's the issue?
[12:26:03] <harmaahylje>	 require_once: did you run the migration script?
[12:26:29] <harmaahylje>	 do you have the same version of mediawiki as was installed in the backup?
[12:30:29] <require_once>	 hello. no. I'm not aware of a migration script. I had mediawiki 1.27.4 on ubuntu 18.04lts. storage medium on which ubuntu was installed began to fail, so i had to image the whole drive asap. I did not have an opportunity to do a proper backup as mentioned on mediawiki. new installation features the same os - ubuntu 18.04lts and i have installed mariadb, php, apache2, mediawiki 1.27.4 (same version).
[12:31:55] <harmaahylje>	 so you have a backup of the database?
[12:33:23] <require_once>	 I still have acces to an old LocalSettings.php, apache2.conf, mediawiki.conf, mediawiki folder from (/var/www/html/mediawiki) and mediawiki mysql database folder (/var/lib/mysql/*) but it's not a backup, just a folder.
[12:34:14] <require_once>	 /var/lib/mysql/mediawiki is still in place, i'm not sure about it's integrity.
[12:38:15] <require_once>	 I have "replicated" entire setup: created identical database, created same user, used same passwords, made sure i'm on the same network. and then i just replaced newly created folders with old ones, hoping that my entire setup will pick it up as it is. I could follow backup instructions if my image was intact, but checksum for my image is incorrect, so i cannot write my image to a drive, so all i have is plain access to old files.
[17:15:13] <hhd>	 Hi all, I'm new to mediawiki and I want to lern it. For example I want to know how a button works, where to find the method which gets triggert when it gets pushed. For example the "Go" button on https://www.mediawiki.org/wiki/Special:AllPages/Extension: How do I find the method/function? 
[17:18:02] <Skizzerz>	 hhd: /includes/specials/SpecialAllpages.php probably
[17:26:24] <hhd>	 Skizzerz do you have to know this structure how mediawiki works or can you search for it? Like I said I'm new to it and want to lern it how it works. Would you recommend starting with the "Code docs" or something else? 
[17:31:27] <Skizzerz>	 I don't know a good way to answer that. You can try starting there and see if that works for you. I personally started by looking at some of the more simple extensions and seeing how they did things, and expanded what I knew from there
[17:31:55] <Skizzerz>	 but that was many years ago, and the code has changed significantly since then. I'm not in a good spot to give advice to someone new on how to get started
[17:33:00] <Skizzerz>	 https://www.mediawiki.org/wiki/How_to_become_a_MediaWiki_hacker has some helpful links in it
[17:34:04] <James_F>	 hhd: The best way to get into code is to use ?uselang=qqx to find the message key, and then grep the code looking for where it's used.
[17:35:23] <James_F>	 hhd: So https://www.mediawiki.org/wiki/Special:AllPages/Extension?uselang=qqx shows that the key for the "Go" button is "allpagessubmit", which leads you to https://github.com/wikimedia/mediawiki/blob/dce7e7c38413415d2f4069c2508073d7dc872e1c/includes/specials/SpecialAllPages.php#L150
[17:35:55] <James_F>	 Obviously, this only works for front-end code that uses interface text, but that's common for a lot of the interesting bits.
[17:37:26] <hhd>	 Skizzerz well, starting with simple extensions is a great idea. I found https://www.mediawiki.org/wiki/Extension:BoilerPlate, will look into that or you know a simpler one?
[17:37:42] <hhd>	 James_F thank you, let me check that
[17:37:50] <Skizzerz>	 I'd suggest a real extension
[17:39:39] <hhd>	 Skizzerz ok, I will try find a simple one
[17:40:23] <Skizzerz>	 if you're interested in how special pages work, look at one that creates a special page, such as https://www.mediawiki.org/wiki/Extension:CiteThisPage
[17:41:03] <Skizzerz>	 built-in special pages generally follow many of the same methodologies, and are found in the /includes/specials directory of the mediawiki codebase
[17:41:11] <hhd>	 James_F sorry right know I don't get it how it works with ?uselang=qqx
[17:41:22] <hhd>	 Skizzerz great, thank you
[17:41:42] <hhd>	 need to bring my kid to sleep, brb 15min
[17:59:05] <metalhead33>	 Regarding my texture-supporting 3D extension thing: is including Three.js an overkill?
[17:59:16] <metalhead33>	 I mean, Three.js is kinda huge, an 1.5 MiB library.
[18:14:31] <James_F>	 metalhead33: It depends on your use cases for the extension. E.g. if it's mostly intended for use in a kiosk inside a museum or other controlled environment, it doesn't need to matter much.
[18:22:09] <metalhead33>	 I want to have multiple canvases, and support for textures. And it seems like I'm the only person on this planet, who ever considered bringing 3D to MediaWiki with texture support.
[18:24:56] <James_F>	 When discussing the 3D extension, we rejected it for Wikimedia due to the security scanning issues.
[18:25:20] <James_F>	 (Before we got to technology selection; not sure if Three.js is the best out there for that.)
[18:31:19] <metalhead33>	 I looked at both 3D and 3DAlloy
[18:31:26] <metalhead33>	 and both lack texture support
[18:37:55] * James_F nods.
[18:52:00] <hhd>	 Skizzerz and James_F thank you guys. You helped me to get started. If you have more useful tips or links, I would be thankful :)  
[18:58:12] <James_F>	 Mostly, just try things out. Start small. MW is insanely huge, don't try to learn it all, no-one does.
[19:03:23] <hhd>	 ok :)  
[19:04:38] <hhd>	 thank you again guys and good night
[19:09:39] <metalhead33>	 And I have decided that I hate Javasscript. Or rather, the way the developers of those two extensions used it. 
[19:09:56] <metalhead33>	 Because my way of coding is to have a hierarchy of abstraction. Lots of small functions calling other functions.
[19:10:05] <metalhead33>	 like say, createTexture, createShader, createMesh, etc.
[19:26:32] <metalhead33>	 So yeah, now all I need is a way to create a canvas within PHP, and tell PHP to use that canvas, and those specific arguments for texture, mesh, shader, etc.
