I'm creating a beamer presentation that uses biblatex with biber and the ieee style with dashed=false to suppress dashing of repeat author names. This compiles find on my MikTeX installation on my laptop, but will not compile on Overleaf.

Further testing on other web-based compilers showed that no TeX live installation recognises the dashed option, with any document class.

MWE:

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[backend=biber, style=ieee, dashed=false]{biblatex}

\begin{document}

\end{document}

How can I get dashed to work with TeX live?

    It works in texlive 2016 but not in 2015. The web-based compilers are quite often a bit outdated. You would need to get an updated version of the style, but I can't tell you if it would work with an older biblatex. – Ulrike Fischer Mar 09 '17 at 10:37
  • Thanks, I feared that would be the case. Looks like there's not much I can do, but I don't use Overleaf too much anyway – Utumno Mar 09 '17 at 12:34
  • according to http://tex.stackexchange.com/questions/357372/overleaf-custom-biblatex-style#comment880278_357372 overleaf uses texlive 2016, but not up-to-date but the one from ubuntu – samcarter_is_at_topanswers.xyz Mar 09 '17 at 13:05

The dashed option was added to biblatex-ieee in version 1.2 released 2016-12-26 (with this commit following discussion on the bugtracker).

Overleaf are currently running biblatex-ieee on version 1.1p from 2016-07-20, so that version does not have the dashed option. I assume that some other online compilers might be similarly behind with their versions.

If you want to use the dashed option with older versions, add

\makeatletter
\DeclareBibliographyOption[boolean]{dashed}[true]{%
  \ifstrequal{#1}{true}
    {\ExecuteBibliographyOptions{pagetracker}%
     \renewbibmacro*{bbx:savehash}{\savefield{fullhash}{\bbx@lasthash}}}
    {\renewbibmacro*{bbx:savehash}{}}}
\makeatother

and then

\ExecuteBibliographyOptions{dashed=false}

to your preamble. (You still can't use dashed=false as loading-time option though, because at that moment the option is unknown - it is only defined later in your document.)

Or use one of the solutions offered in Enabling dashed option for biblatex-ieee style and biblatex ieee style same authors.
