I'm making a book with the koma-script (scrbook) class and I need to add a minitoc at the start of every part and chapter. I found a solution with this post, however it doesn't work with the greek language from babel.

Here is a minimal example:

\documentclass[fontsize=10pt,open=any,twocolumn]{scrbook}[2019/10/12]% needs version 3.27 or newer

\usepackage[greek]{babel}

\providecommand*{\Ifstr}{\ifstr}% added because of changes in upcoming KOMA-Script version 3.28 and \ifstr replaced by \Ifstr in the code (see https://komascript.de/faq_deprecatedif) 
\usepackage{blindtext}
\usepackage{xcolor}

\usepackage{scrwfile}% avoid trouble with the limited number of write handles
\usepackage{xpatch}

\colorlet{partcolor}{blue}
\addtokomafont{partprefix}{\color{partcolor}}% change color of part prefix
\addtokomafont{part}{\normalcolor}% use normal color for part title
%\renewcommand*\partformat{\partname~\thepart}% if you want to remove \autodot from the definition
\RedeclareSectionCommand[
  tocdynnumwidth=true,%
  tocbeforeskip=1em,
  tocindent=1.5em

This puts an error

! Incomplete \iffalse; all text was ignored after line 127.
<inserted text> 
                \fi

Using the polutonikogreek language instead of the greek language puts the same error. I suspect that this is related to the Ifstr\ifstr problem in KomaScript but when the greek language works in a complete book, it doesn't bear this minitoc approach? I need to write some sentences in greek, not the complete book.

  • The error appears with pdflatex. It does not with xelatex or lualatex. Commented Jan 21, 2023 at 16:20
  • Thanks you Simon, I confirm. However, for the moment, I can't compile the complete book with xelatex or lulatex. Maybe is there a solution with pdflatex ? Commented Jan 21, 2023 at 18:15

With \usepackage[greek]{babel} and PDFLaTeX \@Roman is no longer expandable and not suitable to be used as part of a filename, because it contains font switching commands. A simple suggestion would be, to not use \thepart but \the\c@part to build the extensions of the part contents auxiliary files:

\documentclass[fontsize=10pt,open=any,twocolumn]{scrbook}

\usepackage[greek]{babel}

\usepackage{blindtext}

\usepackage{scrwfile}% avoid trouble with the limited number of write handles
\usepackage{xpatch}

But note: If you somewhere switch the part numbering, this would not work. However, because of the optional argument of \parttoc you can alternatively use the original definition and use the optional argument, e.g. \parttoc[I] or \parttoc[examples].

Another alternative would be to locally redefine \ensureascii (and do this also for chapters) while building the file extension:

\usepackage[greek]{babel}

\usepackage{blindtext}

\usepackage{scrwfile}% avoid trouble with the limited number of write handles

This would also fix similar issues with \@Alph or \@alph, e.g., if you have an appendix.

Note also: I've removed some code only to minimize the example a little more.

However, instead of the shown suggestion, I would suggest to use LuaLaTeX and also to remove the experimental package scrwfile. The KOMA-Script manual also suggests to use LuaLaTeX to avoid the “No room for new write” issue.

  • That's great @cabohah, thanks! What to do if I want the summary of the chapters falls just under the part title (no page break) and if I don't want a title to this list of chapters? The script doesn't work if I deactivate listname. And if I don't want a page break after a part, I can use the Mico script. but it isn't useful here, is it? Commented Jan 23, 2023 at 22:09
