Tips and tricks

This page collects tips on how to create good content within the vagaries of the MediaWiki ecosystem. Document Byzantine things and struggles here, and use heading structure appropriately so that items appear in the contents box . Available external help pages are linked to where possible.

Wiki navigation and special pages

Make a new page

Insert a link into an existing page with the name of the new page, save edit, click on link to new page, and lastly edit that new page by clicking "create".

Images

SVG

Using SVGs is preferred for graphics mainly for quality, but also file size. SVGs can be compressed with the https://vecta.io/nano tool and also usually compress further again using zip of server HTML compression. (PNG and JPGs do not compress so differences can easily be 10x.)

Navigation

Side bar editing

Edit source on MediaWiki:Sidebar to change sidebar content.

Navigation popups

Popup error when no text precedes headers.

Navigation popups are nice feature, but all too easy to break or make ugly.

Text required at page head

Before any headers, a paragraph of body text is required for the popup to display correctly and not generate an error. This text should summarise the page in a couple of sentences which is what appears in the popup.

Popup images

To make Navigation_popups show an image (which is preferred), the image apparently needs to be included on the page and downloaded on page load -- if a gallery image, for instance, this is not the case.

Use this <!-- popup [[File:Desired_Preview_Image.jpg]] -->‎ hint in source edit to use any particular image.

Markup

Writing markup and especially writing about markup in markup is maddening.

• Find a good example and use view/edit source (rather than visual editor) to see how things are done.
• Not all/many formatting options are available in visual editor, some things have to be added in source.

<nowiki>‎...‎</nowiki>

<nowiki><nowiki>‎...</nowiki></nowiki>‎

<code><nowiki><!-- popup [[File:Desired_Preview_Image.jpg]] -->‎</nowiki></code>

The <pre> tag ignores [[Wiki]] ''markup''. It also doesn't     reformat text. It still interprets special characters: → 

This example shows how the above markup reference is generated - 
<code><code><nowiki><!-- popup [[File:Desired_Preview_Image.jpg]] -->‎</nowiki></code></code>
...but quoting the </p r e> tag is more difficult.
