Template:Anchor/documentation

Usage

{{Anchor}} or its plural alias {{Anchors}} will insert one or more HTML anchors in a page at the location of its invocation, enabling direct #Links to this location.

Code

Before{{Anchors|Foo|Bar & Baz|Three}}After

Gives

BeforeTemplate:AnchorsAfter

Notes

• The template will handle up to 10 anchor names, but could very easily be extended to do twice or more. If you accidentally use more than 10 anchors, the template will output an error message in a yellow box like this: Template:Anchors This will let you know about it instead of having your extra anchors be silently ignored.

• When used to add anchors to a paragraph of prose, it is preferable to put the template at the very start of the paragraph (stuck to the first word, without space) so as to ensure that incoming #Links will result in the full paragraph be displayed on the reader's screen.

• You can add anchors aliases to a heading by using a syntax such as:

==Heading title {{Anchors|Foo|Bar & Baz}}==

This results in "#Foo" and "#Bar & Baz" being alias targets of "#Heading title". This syntax doesn't alter the heading, which remains a regular heading as functional as if the template wasn't inserted (i.e. still appears in the page's TOC, and section editing works as usual). This method is advantageous in that you can always see the anchors list when editing this section only, and they work exactly like the heading's own regular anchor. (This is not the case when the anchors are added one line above or below the heading. And adding anchors after the heading on the same line doesn't work.) For long aliases, you can also use the vertical format, such as:

==José Álvarez de Toledo y Gonzaga {{Anchors
| Don José Álvarez de Toledo y Gonzaga, 15th Duke of Medina-Sidonia
| Don José Álvarez de Toledo y Gonzaga, 13th Duke of Alba 
| Don José Álvarez de Toledo y Gonzaga, 11th Marquis of Villafranca
}}==

Or combinations of horizontal and vertical, such as:

==George Walker Bush {{Anchors
| George W. Bush | George Bush | Bush | Dubya
}}==

Each format works the same as the others.

• Though aliases {{Anchor}} and {{Anchors}} will work interchangeably, it is preferable to use the singular alias for a single anchor, and the plural alias for multiple anchors. This will allow Special:Whatlinkshere/Template:Anchors to track usage of multiple anchors, and could help detecting and converting old-style {{Anchor|Foo}}{{Anchor|Bar}} to {{Anchors|Foo|Bar}}.

Anchor names

• Anchor names shouldn't include characters "#" (hash), "|" (pipe) or "=" (equal). On the other hand, special characters such as " " (space), "," (comma), "&" (ampersand), etc. can be used directly both in anchors and links, because Wikipedia will process them automatically into an URL-acceptable format.

• Anchor names should preferably use "Sentence case" (as is the standard for headings and thus their anchors) for naming each anchor; that is, capitalize the first letter of the first word and any proper nouns, but leave the rest lowercase. Examples: "The title of my anchor", "The anchor from Ipanema", etc. Because some browsers have case-sensitive anchors, the anchor name used in the #Links should be absolutely identical to its target (rather than all-lowercase).

• Anchor names should be unique (with respect to all heading titles and additional anchors) on each the page; a duplicate anchor won't work since the #Links will always go to the first homonymous anchor on the page.

Linking

After that, you can have links sending directly to the line you marked:

• With [[#Bar & Baz|link label]] when linking from the same page
• With [[Article name#Bar & Baz|link label]] when linking from another page

Technical

• The template is based on <SPAN ID="anchor" />
• The final HTML page (as outputted by Wikipedia to the reader's browser) will have converted it to <SPAN ID="anchor"></SPAN> instead.
• The more backward-compatible <A NAME="anchor" ID="anchor"></A> is used by Wikipedia's own headings but disabled for editors in the wikicode and thus not used here.
