User:Aristeas/Credits/Implementation

This template provides the internal implementation for my personal credits template.

It should not be called directly, but is just called from the concrete credits templates: User:Aristeas/Credits/CC BY-SA 4.0, User:Aristeas/Credits/CC BY-SA 3.0 GFDL 1.2 etc.

Therefore please see these templates for the documention of the public parameters.

Some minor hints about the implementation

• In earlier versions I used (like in the code for the original {{Information}} template) a <div> around the complete <table> element: <div class="hproduct commons-file-information-table"> ... </div>. But the {{Location}} template does not use that <div> at all, so we can omit it.
• Seems that for the <table> the single class="toccolours" is sufficient. But the {{Information}} and {{Location}} templates add more classes, so I add all the classes used by the {{Location}} template, too.
• The <table> element in the standard {{Information}} still uses the attributes dir, lang and cellpadding, so we use them, too (but I wonder if this is really good 21st-century HTML?).
• In order to get the spacing right and to allow several information supplement tables to be merged visually with the {{Information}} template, we must avoid empty lines and even some line breaks in our template code. For example, there must be no newline between </includeonly> and <noinclude>, and it seems that we must even avoid line breaks between the various included category definitions. Else the MediaWiki software thinks that we want a break after our table and adds a nasty <p><br/></p> (or similar) after it.
• The localization for the ‘Attribution’ field uses the same code as the {{Credit line}} template; so look out if that line in the {{Credit line}} template or if any of the subtemplates used there changes, because this may force us to update this template, too.
• Earlier versions of this template added ‘/ Wikimedia Commons /’ right in the middle of the credit line. I have dropped this part in May 2024 for several reasons. Mentioning the platform is not required by the CC licenses themselves; leaving it out makes it easier for re-users to use the credit line; and this also avoids the wrong idea that the files are owned by the Wikimedia Foundation.
