User:Jonathan R. Williford/Help:ScholarWiki

ScholarWiki is the wiki format used by Scholarpedia. It is largely based off of the wiki format used by Wikipedia.

Layout

Sections

Section headings

The = through

==

markup are headings for the sections with which they are associated.

• A single = is styled as the article title and should not be used within an article.
• Headings are styled through CSS and add an [edit] link.
• Four or more headings cause a table of contents to be generated automatically.
• Do not use any markup after the final heading markup – this will either break the heading, or will cause the heading to not be included in an edit summary.

Template:Markup And so on.

Wiki headings translate to HTML heading elements, Template:Tag through Template:Tag, styled as follows by default:

{{#lst:Help:HTML in wikitext|HTML_section}}

Templates: {{fake heading}} for use in documentation.

Horizontal rule

The horizontal rule represents a paragraph-level thematic break. Do not use in article content.

HTML: Template:Tag

Table of contents

When a page has at least four headings, a table of contents (TOC) will automatically appear after the lead and before the first heading. The TOC can be controlled by magic words or templates:

• __FORCETOC__ forces the TOC to appear at the normal location regardless of the number of headings.
• __TOC__ forces the TOC to appear at the point where the magic word is inserted instead of the normal location.
• __NOTOC__ disables the TOC entirely.
• {{TOC limit}} can be used to control the depth of subsections included in the TOC. This is useful where the TOC is long and unwieldy.
• Category:Wikipedia table of contents templates contains a number of specialized TOC templates.

Line breaks

Line breaks or newlines are used to add whitespace between lines, such as separating paragraphs.

• A line break that is visible in the content is inserted by pressing Template:Key press twice.
• Pressing Template:Key press once will place a line break in the markup, but it will not show in the rendered content, except when using list markup.
• Markup such as bold or italics will be terminated at a line break.

HTML: Template:Tag or Template:Tag

Templates:

• {{break}} adds multiple line breaks.
• {{crlf2}} adds a true carriage return and line feed.
• {{-}} adds a break with styling to clear floating elements.
• {{plainlist}} creates an unbulleted list.

Indent text

Indentation is most commonly used on talk pages.

Templates: {{outdent}}, {{outdent2}}

Blockquote

When there is a need for separating a block of text. This is useful for (as the name says) inserting blocks of quoted (and cited) text. Template:Markup

Center text

Template {{center}} uses the same markup. To center a table, see Help:Table#Centering tables. Please do not use Template:Tag: it is obsolete.

Lists

Do not leave blank lines between items in a list unless there is a reason to do so, since this causes the MediaWiki software to interpret each item as beginning a new list.

Definition lists

To list terms and definitions, start a new line with a semicolon (;) followed by the term. Then, type a colon (:) followed by a definition.

Definition lists consist of group names corresponding to values. Group names (terms) are in bold. Values (definitions) are indented. Each group must include one or more definitions. For a single or first value, the : can be placed on the same line after ; – but subsequent values must be placed on separate lines.

HTML: Template:Tag Template:Tag, Template:Tag Template:Tag

Templates: {{defn}}

Retaining newlines and spaces

The MediaWiki software suppresses single newlines and converts lines starting with a space to preformatted text in a dashed box. HTML suppresses multiple spaces. It is often desirable to retain these elements for poems, lyrics, mottoes, oaths and the like. The Poem extension adds HTML-like Template:Tag tags to maintain newlines and spaces. These tags may be used inside other tags such as Template:Tag. CSS styles may be applied to this tag, e.g.: <poem style="margin-left: 2em;">.

Format

Text formatting

Description	What you type	What it looks like
Italics, bold, Template:Smallcaps	To ''italicize text'', just put 2 apostrophes on each side. 3 apostrophes will '''bold the text''' 5 apostrophes for '''''bold italics''''' '''''Italic and bold formatting''''' only works properly within a single line. For text as {{Smallcaps|small caps}}, use a [[Help:Template|template]].

For text as Template:Smallcaps, use a template.
Small chunks of source code within a line of normal text. Code is displayed in a monospace font.	function <code>int m2()</code> is nice	function int m2() is nice
Syntax highlighting for source code. Computer code has colored text and more stringent formatting. For example, to define a function: int m2(), with highlights.	<syntaxhighlight lang="cpp"> #include <iostream> int m2 (int ax, char *p_ax) { std::cout <<"Hello World!"; return 0; }</syntaxhighlight>	<syntaxhighlight lang="cpp"> include <iostream> int m2 (int ax, char *p_ax) { std::cout <<"Hello World!"; return 0; }</syntaxhighlight>
Small text	Use <small>small text</small> if needed. A span tag can set text font-size as being <span style="font-size: 87%">87% of prior size</span>, to match an image caption.	Use small text if needed. A span tag can set text font-size as being 87% of prior size, to match an image caption.
Big text (Obsolete)	Better not use <big>big text</big>, unless <small> it's <big>within</big> small</small> text.	Better not use big text, unless it's within small text.
You can include a non-breaking space (sometimes called non-printing character) where you require two words to always appear together on the same line, such as Mr. Smith or 400 km/h, using &nbsp; in place of a regular space between the two "words" that need to behave as a single word (never be separated on different lines).	Mr.&nbsp;Smith or 400&nbsp;km/h	Mr. Smith or 400 km/h
Extra spacing within text can best be achieved using the pad template.	Mary {{pad|4em}} had a little lamb.	Mary Template:Pad had a little lamb.
Typewriter font (Obsolete) (Also works beyond the end of a paragraph.)	<tt>arrow &rarr;</tt> <tt>''italics'', '''bold'''</tt> <tt>[[wikilink]] New paragraph </tt>started here.	arrow → italics, bold wikilink New paragraph started here.

Links and URLs

Free links

In Wikipedia and some other wikis, free links are used in wikitext markup to produce internal links between pages, as opposed to the concept of CamelCase for the same purpose, which was used in the early days of Wikipedia – see CamelCase and Wikipedia.

In Wikipedia's markup language, you create free links by putting double square brackets around text designating the title of the page you want to link to. Thus, [[Texas]] will be rendered as Texas. Optionally, you can use a vertical bar (|) to customize the link title. For example, typing [[Texas|Lone Star State]] will produce Lone Star State, a link that is displayed as "Lone Star State" but in fact links to Texas.

Link to another wiki article

• Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
• Thus the link hereafter is to the Web address en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Canonicalization.
• A red link is a page that doesn't exist yet; it can be created by clicking on the link.
• A link to its own page will appear only as bold text.

Renamed link

• Same target, different name.
• The target ("piped") text must be placed first, then the text to be displayed second.

What you type	What it looks like
New York also has [[public transport|public transportation]].	New York also has public transportation.

Automatically rename links

• Simply typing the pipe character (|) after a link will automatically rename the link in certain circumstances. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page.
• See Pipe trick for details.

Description	What you type	What it looks like
Automatically hide stuff in parentheses	[[kingdom (biology)|]]	kingdom
Automatically hide the comma and following text	[[Seattle, Washington|]]	Seattle
Automatically hide namespace	[[Wikipedia:Village pump|]]	Village pump
Or both	[[Wikipedia:Manual of Style (headings)|]]	Manual of Style
But this doesn't work for section links	[[Wikipedia:Manual of Style#Links|]]	[[Wikipedia:Manual of Style#Links|]]

Blend link

• Endings are blended into the link.
  • Exception: a trailing apostrophe (') and any characters following the apostrophe are not blended.
• Preferred style is to use this instead of a piped link, if possible.
• Blending can be suppressed by using the [[#Nowiki|Template:Tag]] tag, which may be desirable in some instances.

Description	What you type	What it looks like
Blending active	San Francisco also has [[public transport]]ation. Examples include [[bus]]es, [[taxicab]]s, and [[tram]]s.	San Francisco also has public transportation. Examples include buses, taxicabs, and trams.
Blending suppressed	A [[micro-]]<nowiki />second.	A micro-second

Link to a section of a page

• The part after the hash sign (#) must match a section heading on the page. Matches must be exact in terms of spelling, case, and punctuation. Links to non-existent sections are not broken; they are treated as links to the beginning of the page.
• Include "| link title" to create a stylish (piped) link title.
• If sections have the same title, add a number to link to any but the first. #Example section 3 goes to the third section named "Example section". You can use the pipe and retype the section title to display the text without the # symbol.

What you type	What it looks like
[[Wikipedia:Manual of Style#Italics]] is a link to a section within another page.	Wikipedia:Manual of Style#Italics is a link to a section within another page.
[[#Links and URLs]] is a link to another section on the current page. [[#Links and URLs|Links and URLs]] is a link to the same section without showing the # symbol.	#Links and URLs is a link to another section on the current page. Links and URLs is a link to the same section without showing the # symbol.
[[Wikipedia:Manual of Style#Italics|Italics]] is a piped link to a section within another page.	Italics is a piped link to a section within another page.

Create page link

• To create a new page:
  1. Create a link to it on some other (related) page.
  2. Save that page.
  3. Click on the link you just made. The new page will open for editing.
• For more information, see starting an article and check out Wikipedia's naming conventions.
• Please do not create a new article without linking to it from at least one other article.

Description	What you type	What it looks like
Links to pages that don’t exist yet look red.	The article about [[cardboard sandwiches]] doesn't exist yet.	The article about cardboard sandwiches doesn't exist yet.

Redirects

• Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").
• It is possible to redirect to a section. For example, a redirect to United States#History will redirect to the History section of the United States page, if it exists.

Description	What you type
Redirect to an article	#REDIRECT [[United States]]
Redirect to a section	#REDIRECT [[United States#History]]

Link to another namespace

What you type	What it looks like
See the [[Wikipedia:Manual of Style]].	See the Wikipedia:Manual of Style.

Link to the same article in another language (interlanguage links)

• To link to a corresponding page in another language, use the form: [[language code:Foreign title]].
• It is recommended interlanguage links be placed at the very end of the article.
• Interlanguage links are not visible within the formatted article, but instead appear as language links on the sidebar (to the left) under the menu section "languages".

• NOTE: To create an inline link (a clickable link within the text) to any foreign language article, see Help:Interlanguage links#Inline interlanguage links and consider the usage notes.

Description	What you type
Link from English article "Plankton" to the Spanish article "Plancton". "es" is the language code for "Template:Lang" (the Spanish language).	[[es:Plancton]]
Other examples: French (fr for Template:Lang), German (de for Template:Lang), Russian (ru), and simple English (simple).	[[fr:Plancton]] [[de:Plankton]] [[ru:Планктон]] [[simple:Plankton]]

Interwiki link

• Link to any page on other Wikimedia wikis.
• Note that interwiki links use the internal link style.
• See MetaWikiPedia:Interwiki_map for the list of shortcuts; if the site you want to link to is not on the list, use an external link (see hereafter).
• See also Wikimedia sister projects.

Description	What you type	What it looks like
Linking to a page on another wiki in English. All of these forms lead to the URL http://en.wiktionary.org/wiki/Hello.
Simple link. Without prefix. Named link.	[[Wiktionary:Hello]] [[Wiktionary:Hello|]] [[Wiktionary:Hello|Wiktionary definition of "Hello"]]	Wiktionary:Hello Hello Wiktionary definition of "Hello"
Linking to a page on another wiki in another language. All of these forms lead to the URL http://fr.wiktionary.org/wiki/bonjour.
Simple link. Without prefix. Named link.	[[Wiktionary:fr:bonjour]] [[Wiktionary:fr:bonjour|]] [[Wiktionary:fr:bonjour|bonjour]]	Wiktionary:fr:bonjour fr:bonjour bonjour

Categories

• To put an article in a category, place a link like [[Category:Example]] into the article. As with interlanguage links, placing these links at the end of the article is recommended.
• To link to a category page without putting the article into the category, use a colon prefix (":Category") in the link.

Description	What you type	What it looks like
Categorize an article.	[[Category:Character sets]]
Link to a category.	[[:Category:Character sets]]	Category:Character sets
Without prefix.	[[:Category:Character sets|]]	Character sets

External links

• Square brackets indicate an external link. Note the use of a space (not a pipe) to separate the URL from the link text in the "named" link. Square brackets may be used as normal when not linking to anything – [like this].
• A URL must begin with a supported URI scheme: http:// and https:// will be supported by all browsers; irc://, ircs://, ftp://, news://, mailto: and gopher:// will require a plugin or an external application. IPv6 addresses in URLs are currently not supported.
• A URL containing certain characters will display and link incorrectly unless those characters are encoded. For example, a space must be replaced by %20. Encoding can be achieved by:

• Use the link button File:Vector toolbar insert link button.png on the enhanced editing toolbar to encode the link; this tool will add the bracket markup and the linked text, which may not always be desirable.
• Or manually encode the URL by replacing these characters:

space	"	'	,	;	<	>	?	[	]
%20	%22	%27	%2c	%3b	%3c	%3e	%3f	%5b	%5d

• Or use the {{urlencode:}} magic word. See Help:Magic words in the MediaWiki documentation for more details.

• See External links for style issues, and External link file type templates for indicating the file type of an external link with an icon.

Description	What you type	What it looks like
Named link with an external link icon	[http://www.wikipedia.org Wikipedia]	Wikipedia
Unnamed link (Only used within article body for footnotes)	[http://www.wikipedia.org]	[1]

Link without arrow (Not often used)	<span class="plainlinks">[http://www.wikipedia.org Wikipedia]</span>	Wikipedia

Miscellaneous

"As of" tag

• "As of" tags generate phrases like "As of April 2009" or "as of April 2009", and categorize info that will need updating. For an explanation of the parameters see template documentation.

What you type	What it looks like
{{As of|2009|4|df=us}}
{{As of|2009|4|df=us|lc=y}}

Media link

• To include links to non image uploads such as sounds, use a "media" link. For images, see next section.
• Some uploaded sounds are listed at Commons:Sound.

What you type	What it looks like

Automatic links

Book sources

• Link to books using their ISBN, which creates a link to Special:BookSources. This is preferred to linking to a specific online bookstore, because it gives the reader a choice of vendors. However, if one bookstore or online service provides additional free information, such as table of contents or excerpts from the text, then a link to that source will aid the user and is recommended. ISBN links do not need any extra markup, provided you use one of the indicated formats.
• To create a link to Special:BookSources using alternative text (e.g. the book's title), use the internal link style with the appropriate namespace.

What you type	What it looks like
ISBN 012345678X	ISBN 012345678X
ISBN 0-12-345678-X	ISBN 0-12-345678-X
Link to a book using [[Special:BookSources/0670037818|alternative text, such as its title]]	Link to a book using alternative text, such as its title

RFC number

• Link to an Internet Engineering Task Force Request for Comments (RFC).

What you type	What it looks like
Text mentioning an RFC number anywhere, e.g. RFC 4321.	Text mentioning an RFC number anywhere, e.g. RFC 4321.

Links partially italicized

• Link to a page with words usually italicized, such as Hindenburg disaster.

What you type	What it looks like
[[Hindenburg disaster|''Hindenburg'' disaster]]	Hindenburg disaster

Pronunciation aids

It is often desirable to provide an aid to pronunciation for a word. The IPAc-en and Respell templates can be of assistance.

What you type	What it looks like
'''Konjac''' {{IPAc-en|lang|pron|ˈ|k|oʊ|n|j|æ|k}}	Konjac Template:IPAc-en
'''Konjac''' ({{IPAc-en|lang|pron|ˈ|k|oʊ|n|j|æ|k}} {{respell|KOHN|yak}})	Konjac (Template:IPAc-en Template:Respell)
''Konjac'' is pronounced {{IPAc-en|ˈ|k|oʊ|n|j|æ|k}} in English.	Konjac is pronounced Template:IPAc-en in English.

Refer to Wikipedia:Manual of Style (pronunciation) for more information.

Musical notation

Template:Main Musical notation is added by using the Template:Xtag extension tag. For example:

Tables

Template:Main There are two ways to build tables:

• In special wiki-markup (see Help:Table).
• Using HTML elements: Template:Tag, Template:Tag, Template:Tag or Template:Tag.

See also When tables are appropriate.

References and citing sources

Making a reference citing a printed or online source can be accomplished by using the Template:Tag tags. Inside these tags details about the reference are added.

Details about the citation can be provided using a structure provided by various templates; the table below lists some typical citation components.

What it's for	What you type

Templates and transcluding pages

Examples for templates: {{pad|...}}, {{math|...}}, {{as of|...}}, {{edit}}

Templates are segments of wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}. It is also possible to transclude other pages by using {{:colon and double braces}}.

There are three pairs of tags that can be used in wikitext to control how transclusion affects parts of a template or article. They determine whether or not wikitext renders, either in its own article, which we will call "here", or in another article where it is transcluded, which we will call "there".

• <noinclude>: the content will not be rendered there. These tags have no effect here.
• <includeonly>: the content will render only there, and will not render here (like invisible ink made visible by means of transclusion).
• <onlyinclude>: the content will render here and will render there, but it will only render there what is between these tags.

There can be several such section "elements". Also, they can be nested. All possible renderings are achievable. For example, to render there one or more sections of the page here use <onlyinclude> tags. To append text there, wrap the addition in <includeonly> tags before, within, or after the section. To omit portions of the section, nest <noinclude> tags within it.

If a page is transcluded without transclusion markup, it may cause an unintentional categorization. Any page transcluding it will contain the same category as the original page. Wrap the category markup with <noinclude> tags to prevent incorrect categorization.

Some templates take parameters, as well, which you separate with the pipe character |.

What you type	What it looks like
{{Transclusion demo}}
{{Help:Transclusion demo}}

• The character tilde (~) is used when adding a comment to a Talk page.
• Your username provides a link to your user page.

Description	What you type	What it looks like
You should sign your comments by appending four tildes to the comment, which adds your user name plus date/time.	~~~~	Username (talk) 20:47, 22 December 2024 (UTC)

Show deleted or inserted text

• When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted content.
  • It is best to Template:Tag and Template:Tag.
• When editing regular Wikipedia articles, just make your changes and do not mark them up in any special way.

Limiting formatting / escaping wiki markup

A few different kinds of formatting will tell the wiki to display things as you typed them – what you see is what you get!

'''&lt;nowiki&gt; tag:''' <nowiki> The nowiki tag ignores [[wiki]] ''markup''. It reformats text by removing newlines and multiple spaces.

Nowiki

Template:Tag and Template:Tag tags stop parsing of wiki markup, except HTML character entity references (e.g., for special characters). Unlike Template:Tag, "nowiki" doesn't change formatting.

An example of Template:Tag:

(However in this particular case probably you prefer Template:Tlp to create a link as {{cite book}}, or Template:Tlp prints Template:Tlf.)

A singular Template:Tag can be used to break wikimarkup.

• Markup such as *

, # , ;

and :
only and always take effect at the beginning of a line. A Template:Tag  before the markup will cause the characters to not parse as markup.

• An internal link immediately followed by characters are blended to form a single link. Where this is not desired, add a Template:Tag after the link.
• HTML(-like) tags can be stopped parsing by inserting Template:Tag after the opening angle bracket.

If you want to write tags, {{tag}} template is handy. E.g. Template:Tlp prints Template:Tag.

HTML entities

Template:Tag and Template:Tag parse HTML entities. If you want to escape this, replace & with &.

Use in templates

When used in a template, Template:Tag simply does not work as you may expect.

• Including Template:Tag immediately acts upon the enclosed markup. Attempting to escape or transclude the brackets causes Template:Tag to not work at all.
• Using #tag:nowiki

works, but has major limitations:

• • Templates, parameters, parser functions, and parser magic such as signatures are parsed, not nowikied.
  • Included Template:Tag tags will expose the strip markers.

Pre

Template:Tag is a parser tag that emulates the HTML Template:Tag tag. It defines preformatted text that is displayed in a fixed-width font and is enclosed in a dashed box. HTML and wiki markups are escaped and spaces and line breaks are preserved, but HTML entities are parsed.

Template:Tag formatted text does not wrap, thus text may extend past the browser window:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

To resolve this, Template:Tag may use CSS styling to add wrapping or a horizontal scrollbar:

• Wrapping: Template:Tag
• Scroll bar: Template:Tag

Alternatively, consider using {{pre2}} template or Template:Xtag.

Invisible text (comments)

It's uncommonTemplate:Spaced ndashbut on occasion acceptable for notes to other editorsTemplate:Spaced ndashto add a hidden comment within the text of an article. These comments are only visible when editing or viewing the source of a page. Most comments should go on the appropriate Talk page. The format is to surround the hidden text with "<!--" and "-->" and may cover several lines, e.g.:

<!-- An example of hidden comments
 This won't be visible except in "edit" mode. -->

Another way to include a comment in the wiki markup uses the {{Void}} template, which can be abbreviated as {{^}}. This template "expands" to the empty string, generating no HTML output; it is visible only to people editing the wiki source. Thus Template:J operates similarly to the comment Template:J. The main difference is that the template version can be nested, while attempting to nest HTML comments produces odd results.

Template:Tlf is the number of pages in the main namespace which contain a link and are not a redirect. This includes full articles, stubs containing a link, and disambiguation pages.

Template:Tlf is the genitive (possessive) grammatical form of the month name, as used in some languages but not in English; Template:Tlf is the nominative (subject) form, as usually seen in English.

In languages where it makes a difference, you can use constructs like {{grammar:case|word}} to convert a word from the nominative case to some other case. For example, {{grammar:genitive|{{CURRENTMONTHNAME}}}} means the same as {{CURRENTMONTHNAMEGEN}}.

HTML

Many HTML tags can be used in wiki markup. You can check your HTML by using markup validation.
