https://www.mediawiki.org/wiki/Extension:Variables

It seems {{#vardefine:variablename|specifiedvalue}} and {{#var:variablename}} do not define and retrieving variablename in the Gentoo Wiki User Page.

- - - -

In the source of the handbook below, there are {{#set: architecture=amd64 ... }} as variable definitions.

https://wiki.gentoo.org/index.php?title=Handbook:Parts&action=edit

At the bottom of this source, there is {{#show:Handbook:{{ROOTPAGENAME}}|? architecture}} as the variable retrieval.

https://wiki.gentoo.org/index.php?title=Handbook:Parts/Full/Installation&action=edit

But {{#set ... }} and {{#show ... }} does not work when I am using them in User Page or that Sandbox.

The Gentoo wiki does not have this extra extension installed. I would not suggest adding it with that big warning on the top of the help page either.

#set and #show Parser Functions are part of Semantic MediaWiki and need a SMW property created to save its data.
This is only truly worth the effort to reuse those values over other pages, and really, many of them.

The Handbook is a bit special. It uses various inclusion features to not repeat itself over and over.
With a major benefits of ease of most changes and translations only have to be done once for all arches.

Hi grknight,

Thank you for reply and explanation.

May I ask as the SMW is set up in the Handbook namespace, it is possible to reuse the #set and #show Parser Functions in the User namespace?

On the other hand, I have studies the ParserFunctions below. They work in the User namespace. But it seems that there is no syntax to set and get a variable. Without variable, their functions are quite limited.

Its worth asking/discussing in #gentoo-wiki on libera IRC too.
