Various Trials & Tests

1. First (bad) MediaWiki tests
2. Learning how to modify and enhance the a2Hosting MediaWiki environment.

I'm just testing to see if I'm properly editing. $E=m{c}^2$

Another Test

r-mode image (300 x 225 px)

4 June 2021: I successfully uploaded the "r-mode image" — shown here, on the right — from my Mac to the a2Hosting file system.

1. I pointed my browser to the URL: Tohline.education/SelfGravitatingFluids; this opened the "Main Page" of my MediaWiki app
2. I logged into the MediaWiki site; as a result, the "Upload file" link was added to the left-hand menu
3. Clicking on this "Upload file" link, a familiar MediaWiki page opened; it allowed me to upload a selected r-mode image from my Mac
4. From the a2Hosting's cPanel, I double-clicked on the "File Manager"; I located the file under public_html/SelfGravitatingFluids/images/3/3b

5 June 2021: I found this URL useful as I attempted to change my MediaWiki Logo image.

5 June 2021: via a cPanel-Terminal session, I changed directory to "~/public_html/SelfGravitatingFluids" and …

1. Found index.php; its contents were not immediately useful.
2. Found LocalSettings.php
   1. $wgServer = "https://tohline.education"
   2. $wgScriptPath = "/SelfGravitatingFluids"
   3. $wgResourceBasePath = $wgScriptPath
   4. $wgLogos = [ '1x' => "$wgResourceBasePath/resources/assets/wiki.png" ];

5 June 2021: I realized that, when using the cPanel-File_Manager, I must click on the **name** (e.g., SelfGravitatingFluids) of a directory folder as well as the tiny folder icon in order to see all of the directory's files and sub-directories.

r-mode image (300 x 300 px)

5 June 2021: I successfully uploaded the "r-mode image" — shown here, on the right — from my Mac to the a2Hosting file system.

1. It is 135 x 135 pixels, which is the size used for the replacement MediaWiki Logo; actually, what is displayed here is a 300 x 300 pixel image.
2. From the a2Hosting's cPanel, I double-clicked on the "File Manager"; I located the file under public_html/SelfGravitatingFluids/images/8/8b; actually, the displayed image is in ~/images/9/97
3. Now, let's try opening the LocalSettings.php file and changing the $wgLogos specification to read:
   $wgLogos = [ '1x' => "$wgResourceBasePath/images/8/8a/RmodeHBookImage6.png" ];
4. That did not work, but the following did:
   $wgLogos = [ '1x' => "images/8/8a/RmodeHBookImage6.png" ];
5. I added the "Self-Gravitating Fluids" label to the same image, then repeated the above-enumerated upload steps. Now the appropriate Logo can be found at the following location:
   $wgLogos = [ '1x' => "images/d/d3/RmodeImage8.png" ];

5 June 2021: Where do new MediaWiki pages get stored?

1. Looks like one test example is at: ~/www/SelfGravitatingFluids/tests/phpunit/includes/page/
2. Perhaps the real thing is at: ~/www/SelfGravitatingFluids/includes/page/
3. Even more likely to be useful: ~/www/SelfGravitatingFluids/includes/content/
   88% into TextContent.php … "Generates an HTML version of the content, for display. Used by fillParserOutput() to provide HTML for the ParserOutput object."

8 June 2021: SSH and SFTP.

1. After reading this document, I learned how — from my iMac — to log into the a2Hosting linux servers via a secure shell (SSH; port 7822) session.
2. After reading a separate document, I followed a2Hosting's advice and installed FileZilla on my iMac. This allows me — via a very pleasant "windowed" interface — to establish and use SFTP to transfer files from the iMac to my account on a2Hosting servers.

8 June 2021: Contemplate installation of "Math" extension.

1. Consider reading www.mediawiki.org/wiki/Manual:Configuration_settings
2. Steps drawn from: Extension:Math#Installation
   • Download and place the file(s) in a directory called Math in your extensions/ folder.
   • Add the following code at the bottom of your ~/SelfGravitatingFluids/LocalSettings.php:
     • wfLoadExtension( 'Math' );
   • Run the update script which will automatically create the necessary database tables that this extension needs.
