Re: [NTG-context] How to use "fontsampler example" with Persian font

[Mingranina Gingranina]

Dear Mohammad,
Hello,

\pagenumbering is not defined or redined in XePersian. In fact, in
TeXLive 2016, it is only defined in the following files:

texmf-dist/tex/latex/base/latex.ltx
texmf-dist/tex/latex/feupphdteses/feupphdteses.sty
texmf-dist/tex/latex/kluwer/kluedit.sty
texmf-dist/tex/latex/kluwer/kluwer.cls
texmf-dist/tex/latex/pdfwin/pdfwin.sty
texmf-dist/tex/latex/romanneg/romanneg.sty
texmf-dist/tex/plain/gustlib/plmac218/plidxmac.tex
texmf-dist/tex/plain/makeindex/idxmac.tex

I think it would be better to look at arabluatex's code for solving the problem.

Regards,
Mingranina

Re: [NTG-context] How to use "fontsampler example" with Persian font

[Mohammad Hossein Bateni]

This seems to not belong in the ConTeXt mailing list.  You'd be better off
asking it on Stack Exchange or on luatex mailing list.  The short answer is
it depends on the "format file" (and perhaps the LaTeX packages) you're
using.  Most probably, you either use "plain" or "latex", and then you
should see how they generate the page numbers and define a macro that
provides the Persian numbers, etc.  See how XePersian package handles it.
 (Search for \pagenumbering.)

It is a module for Persian typesetting in ConTeXt. Please see:

I am a novice in LuaTeX and ConTeXt and to learn these I tried to
modify FontSampler code (http://wiki.luatex.org/index.php/Fontsampler)
to get a sample of Persian fonts in a directory hierarchy too.

BTW, at the moment my problem with LuaTeX is that the page numbering
is in english. Do you know how to change the page numbering to Persian
in LuaTeX?

 Thanks,
 Mingranina

Dear Mohammad,
Hi,

Thank you very much for your reply. I forgot to mention that I had
modified the fontsampler codes so that I can use it in ConTeXt with
Dabeer module.

1. What is Dabeer?

2. You can access the list of known fonts with the "fonts.names.list" 
function:


\setuppapersize[A4,landscape]

\starttext

\startluacode

local fontlist = fonts.names.list("",true,true)

context.starttabulate({"|l|l|"})
for fontname, fontentry in next, fontlist do
context.NC()
context(fontentry["rawname"])
context.NC()
context(fontentry["filename"])
context.NC()
context.NR()
end
context.stoptabulate()

\stopluacode

\stoptext

However, inspired by your reply I could get it to work in LuaTeX but
not in ConTeXt with Dabeer module.

Are there any other set of features that I can test?
ConTeXt inludes a few modules which can be used to show font information 
(search for s-fonts-*.mkiv|mkvi and s-math-*.mkiv|mkvi), below is a 
example from s-fonts-tables.mkiv:


\usemodule[fonts-tables]

\setupbodyfont[pagella]

\starttext
\showfonttables[title={TeX Gyre Pagella}]
\stoptext

Re: [NTG-context] How to use "fontsampler example" with Persian font

In ConTeXt, use \definedfont[font-name*arabic] instead of the following two
commands:

\font\myfont=blah blah
\myfont

Re: [NTG-context] How to use "fontsampler example" with Persian font

[Mingranina Gingranina]

 Dear Mohammad,
 Hi,

 Thank you very much for your reply. I forgot to mention that I had
modified the fontsampler codes so that I can use it in ConTeXt with
Dabeer module.

 However, inspired by your reply I could get it to work in LuaTeX but
not in ConTeXt with Dabeer module.

 Are there any other set of features that I can test?

 Thanks,
 Mingranina

Re: [NTG-context] How to use "fontsampler example" with Persian font

[Mohammad Hossein Bateni]

I don't know much about fontsampler but the commands you list here are
mostly irrelevant.  My guess is you will need to set the features in the
font to get proper shaping.  A good set of features that should do the
trick is called "arabic".

When loading the font, you should do something like the following, but I
have not tried it myself.

\font\myfont=file:font.otf:language=dflt;script=arab;ccmp=yes;init=yes;medi=yes;fina=yes;rlig=yes

[NTG-context] How to use "fontsampler example" with Persian font

[Mingranina Gingranina]

Dear All,
 Hello,

 I am trying to use "fontsampler example" with Persian fonts (please
see below or "http://wiki.luatex.org/index.php/Fontsampler";
 for fontsampler codes).
 The problem is that Persian words apears as a string of separate
glyphs, for example I get "ح‌س‌ن" instead of "حسن".
 Do I have to use commands like the followings inside \directlua or
tex.tprint to fix the problem? If yes, how can I do that?

\installlanguage [fa][default=pe,date=\longjalalidatefmt]
\mainlanguage[fa]

\definefontfeature[tlig][tlig=yes]
\definefontfeature[slanted][slant=.2]
\definefontfeature[dlang][language=dflt]
\definefontfeature[flang][language=far]

Thanks
Mingranina
