# BreakURL package using DVIPS only works on URL and not DOI

I've prepared my bibliography using biblatex, and my DOI addresses are not breaking their lines properly. I know that using pdflatex will solve this issue, I have to compile my document using latex -> dvips -> ps2pdf due to using pstricks.

Using the information from Biblatex: URL-breaking not working in DVI-mode, I tried using the breakurl package, and discovered that URLs line-break properly, but the DOIs still do not.

Any help would be appreciated.

Here is a MWE

\documentclass{article}
\PassOptionsToPackage{hyphens}{url}\usepackage{hyperref}
\usepackage[anythingbreaks]{breakurl}
\usepackage[citestyle=authoryear-comp,]{biblatex}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@article{liu2013condition,
title={Condition-based maintenance for continuously monitored degrading blah blah blah longer title},
author={Liu, Xiao and Li, Jingrui and Al-Khalifa, Khalifa N},
journal={IIE Transactions},
volume={45},
number={4},
pages={422--435},
year={2013},
publisher={Taylor and Francis},
doi = {10.1080/0740817X.2012.690930},
}
\end{filecontents}
\usepackage[utf8]{inputenc}
\nocite{*}

\begin{document}

\printbibliography
\end{document}

• With your minimal example, i get a different output and the DOI looks ok. – Johannes_B Mar 25 '15 at 19:43
• That may have been because I forgot to clean my aux files first. I tried it again, and updated the original question. Problem still persists, though. Is it possible that I'm using the wrong sequence of compilers? I am running biber each time too. – jysung Mar 25 '15 at 20:23
• your example is faulty, there is a brace to much in the title. Beside this: DOI is set internally with \hrefand \nolinkurl and this doesn't work with breakurl. – Ulrike Fischer Mar 25 '15 at 22:18
• Thank you, @ulrike-fischer. Does this mean that there is no solution to my problem? – jysung Mar 26 '15 at 2:37
• Well enabling some break points should be easy, but you wouldn't get a sensible hyperlink then as the http://dx.doi.org/ would be missing. – Ulrike Fischer Mar 26 '15 at 8:21

DOI is set internally with \href and \nolinkurl and this doesn't work with breakurl. As far as I can see breakurl has no counterpoint to \nolinkurl, but this seems to work (and gives the correct link):
