  2. MikTex : 21.7 (7/19/2021 release)
  3. Eisvogel : 2.0.0
  4. OS : Mac 11.5.1

Update

If I delete --pdf-engine=xelatex , eisvogel works successfully.

However, my document includes Chinese and must use --pdf-engine=xelatex and -V CJKmainfont to convert the file.

Hope someone can help...

# 您好 Hello

command pandoc example.md -o example.pdf --from markdown --template eisvogel --listings --pdf-engine=xelatex

Same issue here, and I think it's related to Polyglossia - if I remove Polyglossia from the template, everything works as expected.

vizance commented 2 years ago

@cocowalla Thanks for your feedback !

Could you explain more details on removing from which line (Polyglossia) ?

I could see possible related code is from line 433 to line 567 (see below), but not quite sure.

Thank you.

@vizance so basically I'm removing the use of Polyglossia, and always using Babel instead:

Before:

$if(lang)$
  \ifxetex
    % Load polyglossia as late as possible: uses bidi with RTL langages (e.g. Hebrew, Arabic)
    \usepackage{polyglossia}
    \setmainlanguage[$for(polyglossia-lang.options)$$polyglossia-lang.options$$sep$,$endfor$]{$polyglossia-lang.name$}
  $for(polyglossia-otherlangs)$
    \setotherlanguage[$for(polyglossia-otherlangs.options)$$polyglossia-otherlangs.options$$sep$,$endfor$]{$polyglossia-otherlangs.name$}
  $endfor$
  \else
    \usepackage[$for(babel-otherlangs)$$babel-otherlangs$,$endfor$main=$babel-lang$]{babel}
  % get rid of language-specific shorthands (see #6817):
  \let\LanguageShortHands\languageshorthands
  \def\languageshorthands#1{}
  $if(babel-newcommands)$
    $babel-newcommands$
  $endif$
  \fi
$endif$

After:

$if(lang)$
  \usepackage[$for(babel-otherlangs)$$babel-otherlangs$,$endfor$main=$babel-lang$]{babel}
  % get rid of language-specific shorthands (see #6817):
  \let\LanguageShortHands\languageshorthands
  \def\languageshorthands#1{}
  $if(babel-newcommands)$
    $babel-newcommands$
  $endif$
$endif$

I'm using an older version of this template that doesn't have the language specification section - that entire section should also be removed if you have it.

@cocowalla

Great, I will try to remove this section.

thank you so much !

But I need to modify another section to work

Pandoc recently removed polyglossia support in favor of babel (https://github.com/jgm/pandoc/pull/7562). I merged the upstream changes here 496dfcf67f4cf827d18f3f7f19c10beda75fce81. Could you try again?

yanyoliu commented 2 years ago

Yes I tried it, now it works perfect! Thanks
