[Tex/LaTex] how to deal with Long URL in LaTeX

line-breakingurls

I am a green hand in LaTeX. I sought online and found a lot of posts about the question I asked. However, I cannot follow their instructions. Could anyone give me a hand ? (OS is ubuntu 12.04.)

The example code are as follows:

\url{http://www.coreavc.com/index.php?option=com_content&task=view&id=27&Itemid=1com/index.php?option=com_content&task=view&id=27&Itemid=1}

what is the LaTeX code which can wrap this long URL?

The latex code I have is:

The result is like this. For URLs, they do not wrap automatically but go out of the page.

Another approach: Split the linked URL and the link text with \href:

\documentclass{scrartcl} 
\usepackage{hyperref}
\begin{document}

Only Domain:
\href{http://www.coreavc.com/index.php?option=com_content&task=view&id=27&Itemid=1com/index.php?option=com_content&task=view&id=27&Itemid=1}{http://www.coreavc.com}

Domain with description:
\href{http://www.coreavc.com/index.php?option=com_content&task=view&id=27&Itemid=1com/index.php?option=com_content&task=view&id=27&Itemid=1}{http://www.coreavc.com Subpage I want}

Domain with description:
\href{http://www.coreavc.com/index.php?option=com_content&task=view&id=27&Itemid=1com/index.php?option=com_content&task=view&id=27&Itemid=1}{http://www.coreavc.com Start $\to$ Menu 1 $\to$ Menu2}

\end{document}

Text with marked links

Remark for the 3rd version (navigation path): There you can describe how you can find the page via web navigation (or menu pathes). This may also help a reader, if the link will break in future - unless the webpage is reorganized completely.

There are also packages to print menus, e.g. menukeys

[Tex/LaTex] How to deal with bibliography items containing long URLs

Preamble:

\usepackage{url} % hyperref works too
\urlstyle{same}  % (sf also works, for something more subtle than tt)

Then insert urls as:

\url{http://www.example.com/~lev/my%20long%20url}

[Tex/LaTex] Option to break urls with carriage-return symbol

Do you need to use breakurl? If not, \usepackage[hyphens]{url} mostly works (the box around the hypenated URL is not quite right).

\documentclass{article}
\usepackage[hyphens]{url}
\usepackage{hyperref}

\begin{document}
\url{https://tex.stackexchange.com/questions/28835/option-to-break-urls-with-carriage-return-symbol}

\bigskip% An alternative, if this is meant for online use:
\href{https://tex.stackexchange.com/questions/28835/option-to-break-urls-with-carriage-return-symbol}{Question about to break in URLs}
\end{document}

The [hyphens] option also seems to solve the problem with the bibliography (adapted form Url references in bibliography):

\documentclass{article}
\usepackage[hyphens]{url}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Lerner, Ben},
  year = {2011},
  title = {Break URLs},
  url = {http://short.domain.com/very-long-dashed-section},
}
\end{filecontents}

\begin{document}
\nocite{*}
\bibliographystyle{alphaurl}
\bibliography{\jobname}
\end{document}

UPDATE: 2011-09-20:

Borrowing from Replace hyphenation character by a backwards arrow, this uses a \hookleftarrow to be hyphen separator and seems to work. Here I have allowed every character to be breakable, but if that is not desired, you could selectively insert the \BreakableChar only at the characters you want to be breakable:

enter image description here

\documentclass{article}
\usepackage{hyphenat}
\usepackage{url}
\usepackage{xstring}
\usepackage{forloop}
\usepackage{xcolor}
%\usepackage{filecontents}

\newsavebox\MyArrowBox%
\sbox\MyArrowBox{$\hookleftarrow$}%
\makeatletter%
\newcommand*{\BreakableChar}{%
  \leavevmode%
  \prw@zbreak%
  \discretionary{\usebox\MyArrowBox}{}{}%
  \prw@zbreak%
}%

\newcounter{index}%
\newcommand{\AddBreakableChars}[1]{%
  \StrLen{#1 }[\stringLength]%
  \forloop[1]{index}{1}{\value{index}<\stringLength}{%
    \StrChar{#1}{\value{index}}[\currentLetter]%
    {\currentLetter\BreakableChar}%
  }%
}%

\newcommand*{\MyUrl}{https://tex.stackexchange.com/questions/28835/option-to-break-urls-with-carriage-return-symbol}%

\begin{document}
\parbox{4cm}{\textcolor{blue}{\AddBreakableChars{\MyUrl}}}

\bigskip
\parbox{7cm}{\textcolor{blue}{\AddBreakableChars{\MyUrl}}}
\end{document}
