Text Formatting ⇒ polyglossia | Associate '\nonfrenchspacing' with a Language

[Laurentius]

When I change to another language and back, the effect of \nonfrenchspacing has disappeared. What to do? (I'm using XeLaTeX and polyglossia)

[cgnieder]

This seems to work:

Code: Select all

\documentclass{scrartcl}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage{french}
\begin{document}
non french: text. and more text

\textfrench{french: text. and more text}

non french: text. and more text

\begin{french}
 french: text. and more text
\end{french}

non french: text. and more text
\end{document}

I'm not talking about extra space before cola &c. The effect of \nonfrenchspacing is extra space added after full stops, e.g. \xspaceskip=1em plus .4em minus .2em

[cgnieder]

I know that. That's why I added the fullstop in the example. And as I said: it seems to work. You can see it more clearly here:

Code: Select all

\documentclass{scrartcl}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage{french}
\begin{document}
\setlength\parindent{0pt}

non french: text. and more text \\
non french: text.\ and more text

\begin{french}
 french: text. and more text \\
 french: text.\ and more text
\end{french}

non french: text. and more text \\
non french: text.\ and more text
\end{document}

Oh, sorry. Still, I need it to work with \selectlanguage, since I use need the language (and font) automatically to change when a greek character occurs, with something like

Code: Select all

%Languages and fonts
\newcommand\defaultlanguage{danish}
\setdefaultlanguage{\defaultlanguage}
\setotherlanguage[variant=ancient]{greek}
\setotherlanguage{french}
\setotherlanguage{english}
\setotherlanguage[spelling=old]{german}
\setmainfont[
	Numbers=Lowercase,
	Mapping=tex-text,
	ItalicFont={[caslon.it.otf]}
	]{[caslon.otf]}
%\newfontface\longs[Numbers=Lowercase, Ligatures=Rare, Mapping=longs]{[caslon]}
%\newfontface\nolongs[Numbers=Lowercase]{[caslon]}
\newfontfamily\greekfont[Numbers=Lowercase]{[Garamond.otf]}

\def\XeTeXcharclasses[#1-#2]#3{
	\newcount\c
	\c=#1
	\XeTeXcharclass\c=#3
	\loop\ifnum\c<#2
		\advance\c by 1
		\XeTeXcharclass\c=#3
	\repeat
	}
\XeTeXinterchartokenstate=1
\newXeTeXintercharclass\greekchar
\XeTeXcharclasses["0370-"03FF]\greekchar
\XeTeXcharclasses["1F00-"1FFF]\greekchar
\XeTeXinterchartoks 0 \greekchar {\selectlanguage{greek}\nonfrenchspacing}
\XeTeXinterchartoks 255 \greekchar {\selectlanguage{greek}\nonfrenchspacing}
\XeTeXinterchartoks \greekchar 0 {\selectlanguage{\defaultlanguage}\nonfrenchspacing}
\XeTeXinterchartoks \greekchar 255 {\selectlanguage{\defaultlanguage}\nonfrenchspacing}
\XeTeXinterchartoks \greekchar \french@punctguillend {\selectlanguage{\defaultlanguage}\nonfrenchspacing\nobreakspace}

[cgnieder]

Could you make that a compilable minimal working example which shows the issue so that I (or any other person willing to help) can experiment with it, please?

All right. I want the last line to have a space after the period without having to repeat \nonfrenchspacing

Code: Select all

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage{german}
\xspaceskip=2em
\nonfrenchspacing
\begin{document}
\obeylines
Quick. Fox

\selectlanguage{german}
Brown. Dog

\selectlanguage{english}
Lazy. Bum
\end{document}

[cgnieder]

IMHO the easiest would be to define a new command which selects the language and sets the correct spacing. Since the package xparse has been by loaded by fontspec which in turn has been loaded by polyglossia you can use its commands:

Code: Select all

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguages{german,french}

% s = star
% m = mandatory argument
\NewDocumentCommand\uselanguage{sm}{%
  \selectlanguage{#2}%
  % if `star' then set \frenchspacing, else \nonfrenchspacing :
  \IfBooleanTF{#1}{\frenchspacing}{\nonfrenchspacing}}
\xspaceskip=2em
\nonfrenchspacing
\begin{document}
\obeylines
Quick. Fox

\uselanguage{german}
Brown. Dog

\uselanguage*{french}
Brown. Dog

\uselanguage{english}
Lazy. Bum
\end{document}
