Template:Code/doc

Usage
Wraps a short span of text in  tags (see mw:Extension:SyntaxHighlight GeSHi). This template should be used for short samples; longer content should use  or . See w:Help:Wiki markup for an explanation of what the various tags do.

If the content includes an equals sign (=), you must specify the parameter explicitly:.

The template uses the  tag with the attribute. This works like the combination of the  and   tags, applied to the expanded wikitext. For example,  will not render the word "wiki" in bold, and will render the tripled-single-quotes:


 * some wiki text

However,  will still invoke the template:


 * a call

Use  around the template name to avoid this problem:


 * a call

When used inline with regular text, generally looks best and is easiest to read when it is explicitly spaced apart from the regular text:
 * foo bar baz quux.

is well spaced:
 * foo bar baz  quux.

versus:
 * foo bar baz quux.

which is going to be visually confusing for many:
 * foo bar baz quux.

because "foo" and "bar" will seem more closely associated than "bar" and "baz"; the width of the space character in a monospaced font is almost always larger than in a proportional font.

Use parameter (unnamed, as 2, or more explicitly as lang) to specify a language for Extension:SyntaxHighlight GeSHi. This option defaults to plain-text, i.e. no highlighting. There is no highlighting option for wikitext as a markup language, though html4strict and html5 are valid values, as are php, perl, css, javascript, mysql and many others. Attempting to use an invalid one causes a list of valid ones to be displayed in place of the template output, when the page is previewed or saved.

This template does not need to be substituted.

Finally, embedded templates do not function inside ; for longer, free-form blocks of code, which can contain templates such as and, use  as a wrapper instead of this template.
