Hello,

This was lost in the other thread, so I'm starting a fresh one dedicated to the question.

1) \showinstalledlanguages does not show pe/persian/fa or anything like that but it has several arabic variants.  was this dropped in MkIV or was there never a persian language environment even in MkII?  I thought there were translated labels for Farsi somewhere.
2) In the following MWE, ad-hoc hyphenation using \- works and leads to hyphenation.  However, specifying the pattern at the beginning does not have any effect.  Am I missing something?


\usemodule[simplefonts]
\setmainfont[dejavusans][features=arabic,range=arabic]
\setupalign[r2l]
\showframe
\hyphenation{سازمان‌-دهی}

\starttext

%% The above pattern is not used here and the long word moves into the margin.
\dorecurse{14}{سلام }
سازمان‌دهی
مناسب.

%% It does work here, though.
\dorecurse{14}{سلام }
سازمان\-دهی
مناسب.

\stoptext


How can one create a new language?  The languages manual suggests that this is possible.  Does that mean I need to send the request to Hans/Wolfgang to create the new entry or can one do so dynamically?  Beside the issue of sorting in indices, etc.—which I will get to in due time—having an entry for language pe/persian seems to be necessary to properly use \setuplabeltext, etc.  Is that correct?
You can create a new language (and synonyms for it) with the \installlanguage command, below is a slightly modified version of the arabic entry. You can change the values for leftquotation etc. and send the result to Hans.

% this goes into mult-sys.mkiv

\definesystemconstant {persian}         \definesystemconstant {fa}

% this goes into lang-def.mkiv

\installlanguage
  [\s!fa]
  [\c!spacing=\v!broad,
   \c!leftsentence=\emdash,
   \c!rightsentence=\emdash,
   \c!leftsubsentence=\emdash,
   \c!rightsubsentence=\emdash,
   \c!leftquote=\upperleftsinglesixquote,
   \c!rightquote=\upperrightsingleninequote,
   \c!leftquotation=\upperleftdoublesixquote,
   \c!rightquotation=\upperrightdoubleninequote,
   \c!date={\v!day,\space,\v!month,\space,\v!year}]

\installlanguage [\s!persian] [\s!fa]

\installlanguage[\s!fa-ir][\c!default=\s!fa]


The default labels for the languages are stored in lang-txt.lua, you can add entries for persian and send the modified file to Hans.
