\use[module=packages.url]

This package enhances the typesetting of URLs in two ways.

First, it provides the \autodoc:command{\href[src=<url>]{<content>}} command which inserts PDF hyperlinks, \href[src=http://www.sile-typesetter.org/]{like this}.

The \autodoc:command{\href} command accepts the same \autodoc:parameter{borderwidth}, \autodoc:parameter{bordercolor}, \autodoc:parameter{borderstyle}, and \autodoc:parameter{borderoffset} styling options as the \autodoc:command[check=false]{\pdf:link} command from the \autodoc:package{pdf} package, for instance \href[src=http://www.sile-typesetter.org/, borderwidth=0.4pt, bordercolor=blue, borderstyle=underline]{like this}.

Nowadays, it is a common practice to have URLs in print articles (whether it is a good practice or not is yet \em{another} topic).

Therefore, the package also provides the \autodoc:command{\url} command, which will automatically insert breakpoints into unwieldy URLs like \url{https://github.com/sile-typesetter/sile-typesetter.github.io/tree/master/examples} so that they can be broken up over multiple lines.

It allows line breaks after the colon, and before or after appropriate segments of an URL (path elements, query parts, fragments, etc.).

By default, the \autodoc:command{\url} command ignores the current language, as one would not want hyphenation to occur in URL segments.

If you have no other choice, however, you can pass it a \autodoc:parameter{language} option to enforce a language to be applied.

Note that if French (\code{fr}) is selected, the special typographic rules applying to punctuations in this language are disabled.

To typeset a URL and also make it an active hyperlink, use the \autodoc:command{\href} command without the \autodoc:parameter{src} option,

but with the URL passed as argument.

The breaks are controlled by two penalty settings: \autodoc:setting{url.linebreak.primaryPenalty} for preferred breakpoints and, for less acceptable but still tolerable breakpoints, \autodoc:setting{url.linebreak.secondaryPenalty}—its value should logically be higher than the previous one.

The \autodoc:command{\urlstyle} command hook may be overridden to change the style of URLs.

By default, they are typeset as “code”.
