Template:URL2

Template documentation[view] [edit] [history] [purge]

This template uses Lua:

This is a fork of Template:URL for use in infoboxes.

It behaves similarly to {{URL}} with the following exceptions:

By default it does not display anything if the parameters are blank or omitted. Template:URL displays {{URL|example.com|optional display text}} by default.
It implements a parameter |msg= that turns on or off the message {{URL|example.com|optional display text}}. Setting msg to false or anything beginning with n or N will suppress the message. Anything else enables the message.
It strips html tags and wiki-link markup from the supplied url parameter.
It truncates the url parameter at the first space it finds.
It can take its own output as input, allowing website parameters to be wrapped in in the design of an infobox, without causing problems if editors add |website={{URL|some.url.com}} in an article.

Usage

If there is no input, the default behavior of URL2 is to display nothing (use |msg= to display the instructional message):

URL2 handles formatting commonly found in the |website= parameter of an infobox:

The template wraps the output in <span class="url">...</span> (see § Microformat) and adds <wbr/> before displayed periods:

{{URL2|www.example.com}} → www.example.com

<span class="url">[http://www.example.com www<wbr/>.example<wbr/>.com]</span>

The use of http://, https://, a protocol-relative URL, or a different protocol is preserved in the URL but is not shown in the link text:

{{URL2|http://www.example.com}} → www.example.com

<span class="url">[http://www.example.com www<wbr/>.example<wbr/>.com]</span>

{{URL2|https://www.example.com}} → www.example.com

<span class="url">[https://www.example.com www<wbr/>.example<wbr/>.com]</span>

{{URL2|//www.example.com}} → www.example.com

<span class="url">[//www.example.com www<wbr/>.example<wbr/>.com]</span>

{{URL2|ftp://ftp.example.com}} → ftp.example.com

<span class="url">[ftp://ftp.example.com ftp<wbr/>.example<wbr/>.com]</span>

If the path is only a slash (/) it is not displayed in the link text:

{{URL2|https://www.example.com/}} → www.example.com

<span class="url">[https://www.example.com/ www<wbr/>.example<wbr/>.com]</span>

The template also adds <wbr/> before any displayed slashes (/) in the path:

{{URL2|https://www.example.com/path}} → www.example.com/path

<span class="url">[https://www.example.com/path www<wbr/>.example<wbr/>.com<wbr/>/path]</span>

For a URL containing an equal sign (=), use |1=:

{{URL2|1=http://www.example.com/path?section=17}} → www.example.com/path?section=17

<span class="url">[http://www.example.com/path?section=17 www<wbr/>.example<wbr/>.com<wbr/>/path?section=17]</span>

The template wraps the displayed URL with class="url" so that it is included in any parent microformat which takes a URL parameter - see Wikipedia:WikiProject Microformats.
