# Underlined URLs with line breaks in formatted bibliographic entries

Requirements:

• Underlined URLs in a bibliography built from an external file.
• Margins are respected. No URLs go into the margins.
• The final output is a pdf file.
• Other format requirements still apply, like the KOMA class and such. This is for meeting thesis formatting requirements.

I would like to have underlined URLs with line breaks. I have tried a couple of approaches:

1. Using the packages url and ulem. This gives underlining but the page margins are not respected. I.e., no line breaks.

\usepackage{url}
\urlstyle{same}%Use the same font and style as the main document.
\usepackage[normalem]{ulem}
\def\UrlLeft#1\UrlRight{%
\expandafter\uline\expandafter{#1}
}

2. I have tried using the soul package with the \ul command. That did not work.

3. I tried inserting the \ul, and \uline command in the url field in the bib entry in the external .bib file.

Sample bib:

% Encoding: UTF-8

@Misc{Author,
author =       {Some Author},
title =        {A Title for a website},
howpublished = {\url{https://AVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURL}},
note =         {(Accessed on 10/07/2017)},
review =       {my Review},
url =          {https://AVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURLAVeryLongURL}
}

• Just out of idle curiosity: What's the purpose of underlying URL strings? (I haven't seen such formatting in a dozen years or more...) – Mico Oct 7 '17 at 23:44
• Package hyperref can draw a line under the link, or a whole box around it (default ctaually). This box or line will not be printed, it is just for highlighting the link in the pdf. Nobody needs a highlighted link in a printed version. – Johannes_B Oct 8 '17 at 6:29
• Your best chance of not going out of the margin is to put \raggedright before the bibliography. It is quite common to do so. – Johannes_B Oct 8 '17 at 6:32

I ended up going with a href solution. The key take away for me was to set up the href with hidelinks then set the hyper style right before the bibliography. The underlines are not as pretty as \underline, \ul, or \uline. But I am pretty sure it meet the formatting requirements for my thesis.

Here is the MWE that I ended up with.
