Interwiki

This is the Interwiki module made by the SCP Wiki, the English-speaking branch of SCP, for all branches of the international SCP and Wanderers' Library communities.

This Interwiki module is forked from SCP 基金会, the Chinese branch of SCP, and was originally made by @7happy7 and @Sekai-s.

The Interwiki is for cross-linking translations of articles between international branches. Placed on any page in the SCP or WL community, the Interwiki will list pages with a matching 'fullname' / 'UNIX name' / URL from other branches of that community.

The Interwiki can be styled with CSS and has no limit on the number of styles that can be applied to it.

Usage

To use the Interwiki on your Wikidot site:

Installing the base Interwiki

You need to know which page is going to contain the Interwiki. The contents of this page must appear on every page that intend to link to its translations, so choices are limited:

• SCP sites typically place the Interwiki in the sidebar, which is configured to appear on every page, and by convention is located at fullname nav:side.
• WL sites typically place the Interwiki in the default page template, the contents of which by definition appear on every page, located at fullname _template.

On this page, create an iframe containing the html/interwikiFrame.html file, passing it some URL query parameters. Use a ListPages module to pass it information about the current page.

[[div class="scpnet-interwiki-wrapper interwiki-stylable"]]
[[module ListPages range="." limit="1"]]
[[embed]]
<iframe src="//SITE.wdfiles.com/local--files/PAGE/interwikiFrame.html?lang=LANG&community=COMMUNITY&pagename=%%fullname%%" allowtransparency="true" class="html-block-iframe scpnet-interwiki-frame"></iframe>
[[/embed]]
[[/module]]
[[/div]]

There are a few placeholders in that URL that must be changed:

• SITE: The UNIX name of the Wikidot site that interwikiFrame.html has been uploaded to. The SCP Wiki (scp-wiki) has this file uploaded already, so you can just set it to that, unless you wish to upload the file to your wiki yourself.
• PAGE: The fullname (a.k.a. page UNIX name) of the page that interwikiFrame.html has been uploaded to. This SCP wiki has this file uploaded to the page at fullname nav:side.
• LANG: The language code of your site, as defined in either js/branches-info-scp.js or js/branches-info-wl.js, depending on the community.
• COMMUNITY: The community that the current page belongs to. Can be either scp or wl. If your site hosts pages from only one community, just add it; if your site hosts pages from both communities, you may wish to use ListPages to detect which one the current page belongs to (see collapsible below).

If you are using the SCP Wiki's copy of interwikiFrame.html (and styleFrame.html), you do not need to upload any files to Wikidot.

Note that the URL in the iframe starts with // rather than http:// or https://. This is a protocol-relative URL, which will preserve the type of connection the user is using, and ensures that the Interwiki works regardless of whether the site is configured to use HTTP or HTTPS (or both).

Note the interwiki-stylable class in the wrapping container. This indicates to CSS themes that the interwiki is capable of being styled itself, and does not need to have styles externally approximated (e.g. by using CSS filters). This is used by themes targeting multiple sites with Interwikis that may or may not be this new Interwiki, such as Black Highlighter, for example.

Example of using ListPages to determine community

This example uses two ListPages modules with category filters to determine which community the current page belongs to. This specific example assumes that pages in the wanderers or wanderers-adult categories belong to WL, and any others belong to SCP.

The category filters are mutually-exclusive, so this will never produce more than one Interwiki per page.

[[div class="scpnet-interwiki-wrapper interwiki-stylable"]]
[[module ListPages range="." limit="1" category="-wanderers -wanderers-adult"]]
[[embed]]
<iframe src="//SITE.wdfiles.com/local--files/PAGE/interwikiFrame.html?lang=LANG&community=scp&pagename=%%fullname%%" class="html-block-iframe scpnet-interwiki-frame"></iframe>
[[/embed]]
[[/module]]

[[module ListPages range="." limit="1" category="wanderers wanderers-adult"]]
[[embed]]
<iframe src="//SITE.wdfiles.com/local--files/PAGE/interwikiFrame.html?lang=LANG&community=wl&pagename=%%fullname%%" class="html-block-iframe scpnet-interwiki-frame"></iframe>
[[/embed]]
[[/module]]
[[/div]]

Styling the Interwiki

The Interwiki, by default, only has default Wikidot styling. To style it further, a styleFrame must be added. A styleFrame applies CSS styling to the interwikiFrame.

To add a styleFrame to a Wikidot page:

[[embed]]
<iframe src="//SITE.wdfiles.com/local--files/PAGE/styleFrame.html?priority=PRIORITY&theme=THEME&css=CSS" style="display: none;"></iframe>
[[/embed]]

There are a few placeholders in that URL that must be changed:

• SITE: The UNIX name of the Wikidot site that styleFrame.html has been uploaded to. The SCP Wiki (scp-wiki) has this file uploaded already, so you can just set it to that, unless you wish to upload the file to your wiki yourself.
• PAGE: The fullname (a.k.a. page UNIX name) of the page that styleFrame.html has been uploaded to. The SCP wiki has this file uploaded to the page at fullname nav:side.
• PRIORITY: The priority of the styling that this styleFrame applies. Corresponds to the internal sort order of the CSS. The base theme of the site should have a priority of 0. The priority number of any other CSS theme should be the priority number of the theme it extends, plus one. The Interwiki will raise a warning in the browser console if it encounters two styles with the same priority number.
• THEME: A pointer to a CSS stylesheet to apply to the Interwiki. May be one of the following values:
  • The fullname of a page on the same site as the Interwiki's language code. The first code block on that page will be imported as CSS.
  • A fullname of page on that site, with /code/n appended to refer to the nth code block.
  • A full URL to any CSS stylesheet on any site. (Useful for e.g. sandbox wikis that do not have their own Interwiki configuration.)
• CSS: URI-encoded CSS to apply directly to the Interwiki.

The theme and css parameters determine the CSS styling that the styleFrame adds. At least one must be present for the styleFrame to do anything. If both are present, the styling from theme will be added before the styling from css.

Note the style="display: none;" at the end of the styleFrame iframe. This just hides the iframe — it doesn't set the style of the Interwiki.

Adding default styling

To add default styling to your site's Interwiki, on the same page as the interwikiFrame iframe, add a styleFrame with priority=0.

For example, the following interwikiFrame and styleFrame would be on the page nav:side of the SCP Wiki:

[[module ListPages range="." limit="1"]]
[[embed]]
<iframe src="//scp-wiki.wdfiles.com/local--files/nav:side/interwikiFrame.html?lang=en&community=scp&pagename=%%fullname%%" class="html-block-iframe scpnet-interwiki-frame"></iframe>
[[/embed]]
[[/module]]

[[embed]]
<iframe src="//scp-wiki.wdfiles.com/local--files/nav:side/styleFrame.html?priority=0&theme=component:theme" style="display: none;"></iframe>
[[/embed]]

Adding additional styling

To add additional styling (e.g. for a CSS theme to add its own styling to the Interwiki), another styleFrame should be added to that theme, with a higher priority number.

CSS themes hosted on your site are expected to be used via Wikidot [[include]]. If this is the case, [[include]]ing CSS themes that style the Interwiki should result in styling being applied as expected, so long as all CSS themes used have the correct priority number.

For example, for a CSS theme on the SCP Wiki located at the page theme:my-theme, with a single code block containing all the CSS including CSS that will be applied to the Interwiki, intended to be used via [[include theme:my-theme]]:

[[iframe https://scp-wiki.wdfiles.com/local--files/nav:side/styleFrame.html?priority=1&theme=theme:my-theme style="display: none;"]]

In this example, the theme theme:my-theme is an extension to Sigma-9 (which, being the base theme of the site, has a priority number of 0), so its priority is 1 (Sigma-9's priority plus one).

Writing CSS

The internal structure of the Interwiki is designed to be consistent with the standard sidebar used on SCP sites.

The Interwiki is a single html#interwiki body div.side-block. Inside is a div.heading p, which is the title of the side block. Beneath the .heading, a series of div.menu-item[name] will be created, with the value of name corresponding to the branch's language code. If the link points to the original article rather than a translation, the element will also have class .original.. Inside each .menu-item is an img.image containing the Sigma-9 bullet point, followed by an a[href] for the translation link.

Do not add margin or padding to either html or body, as this will cause a vertical scrollbar to appear on the Interwiki.

Development

Install locally with NPM: npm install

We use Prettier for formatting: npm run format

To test locally, run npm run serve, note the local IP for the server, and follow the usual setup instructions using it as the hosted location. On page refresh the iframe will be reloaded with any new changes without needing to be recompiled.

To build, run npm run build. Output can be found in the dist/ directly, and all files present should be hosted for usage.

All JavaScript should be written in ES5.
