Indeed… ConTeXt is so rich! Probably I use only one or two per cent of its 
capabilities, but still I am happy and often amazed…

Hi Fabrice,

Do you know the step charts module in ConTeXt? I guess you can achieve what you 
want as in the example below (sorry, I did not took your example, I am just 
copying an example from my archives…).

%%
\usemodule[steps]
\starttext

Pour voir que la composée de deux fonctions $f$ et $u$, continues en un point 
$x_{*}$, est continue, on peut suivre le schéma suivant~:
\placefigure[middle,none][-]{}{
%\scale[,width=.35\textwidth]{
\startSTEPtable 
\cell {$(f\circ u)(x_{*} + o(1)) = $} \text{définition de $f\circ u$}
\cell {$f\left(u\left(x_{*} + o(1)\right)\right) = $} \text {$u$ est 
continue} 
\cell {$f\left(u(x_{*}) + o(1)\right) = $} \text {$f$ est continue} 
\cell {$f\left(u(x_{*})\right) + o(1) =$} \text {définition de $f\circ 
u$} 
\cell {$(f\circ u)(x_{*}) + o(1)$.} 
\stopSTEPtable

Re: [NTG-context] Question about \definefallback

2016-07-25 Thread Jean-Pierre Delange


Dear List,

I answer to myself (or I give a solution to the problem I have to face). 
As for this precise case (i.e. having multilanguages in the same 
document with French as main language, with some words, sentences or 
whatever in  Ancient Greek, Chinese and Arabic/Persian/Farsi), the 
working solution is the \definefallbackfamily command with the 
\definefontfamily (as everybody knows !). In this case, I 've failed to 
deal with Arabic/Farsi (when I wanted to print the name of the Arabic 
medieval philosopher Fārābī, محمد فارابی


The code was : \definefallbackfamily [mainface] [sans] 
[hussaininastaleeq] [range=arabic], and it doesn't work.
I've tried this : \definefallbackfamily[mainface] [serif] 
[nafeesnastaleeq] [range=arabic,farsi] and it works.

A beginner's mistake, if I summarize...
JP

Dear List,

Working with ConTeXt MK IV version 2016.07.18, I need sometimes within 
a text in French I am working on, some Greek words or sentences, 
rarely Chinese and Arabic words, mainly names and a few words.


Then, I use this general preamble (thanks to Pablo Rodriguez):

\setuplanguage[fr][patterns={fr,agr}]

\mainlanguage[fr]

\setuplayout [backspace=40mm]

\setuppagenumbering[alternative=doublesided, location={header, inmargin}]

\setupmargindata[inmargin][location=inner, 
style={\ssx\setupinterlinespace[line=2.8ex]}]


\setupmarginframed[inmargin][align=right]

\setupbodyfontenvironment[default][em=italic]


% Hereafter the commands for Greek and Chinese

\definefallbackfamily[mainface][serif][Theano 
Didot][preset=range:greek, it={Old Standard Italic}, force=yes]


\definefallbackfamily [mainface] [rm] [ipaexmincho] 
[range=cjkunifiedideographs]


\definefontfamily [mainface] [serif] [GaramondNo8][sc=NewG8 Regular SC]

\definefontfamily [mainface] [sans] [FreeSans] [rscale=0.7]


All is working well, but if I add these lines below to the pramble:


\definefallbackfamily [mainface] [sans] [hussaininastaleeq] [range=arabic]

 \definefontfamily [mainface] [serif] [GFS Didot]
(where hussainiastaleeq and GFS Didot fonts are pre-installed, and 
load with a '|mtxrun --script fonts --reload' command), then Arabic 
words are not printed in the PDF file.


One more question : in the English translitteration, the name of the 
tenth century Arabic philosopher, Farabi, is |Abū Naṣr al-Fārābī (with 
diacritic signs on wovels and under the 's' of "Nasr"). Do someone 
knows how to deal with these diacritic signs ?

Thak you very much.
JP
