While you're at it, could you also add something like jday, jmonth, jmm, jyear, etc. to use the Jalali calendar instead of the Gregorian? I see that the—commented—conversion code exists in core-con.lua. I am willing to provide test cases for the conversion. Thanks! —MHB On Thu, Jul 7, 2016 at 4:53 AM, Mohammad Hossein Bateni wrote:

Wolfgang & Hans,

In customizing the date, is there a way to use a number converter on day and year? In particular, I'd like to apply persiandecimals conversion on them. (I have a similar question regarding \currentime.)

Thanks! —Hossein

Mohammad Hossein Bateni 6. Juli 2016 um 20:02 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 http://www.pragma-ade.nl/general/manuals/languages-mkiv.pdf 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.

When naming these macros I would recommend to not use abbreviations like \jday, \jdate but rather using more explicite names like for example \jalaliday. Otherwise confusion with \jdate as a date in the Julian calendar easily could result. Hans van der Meer

Thanks, Wolfgang! BTW why doesn't the following work? it gives the 'missing number' error. % \mainlanguage[en] \romannumerals{\currentdate[day]} On Thu, Jul 7, 2016 at 10:02 AM, Wolfgang Schuster < schuster.wolfgang@gmail.com> wrote:

You can only change the numbers for the day (see below, I used greek to demonstrate it) but it could be done better (e.g. \currentdate[persian->day,space,month,persian->month] with "->" as separator for the conversion and keyword).

%% begin example \installlanguage[fa][state=start]

\defineconversion[fa][day][α,β,γ,δ,ε,ζ,η,θ,ι,κ,λ,μ]

\setupbodyfont[pagella]

\starttext

\currentdate[day]

\language[fa]

\currentdate[day]

\stoptext %% end example

(I have a similar question regarding \currentime.)

Not possible at the moment.

Wolfgang

Is there a trick to get over this issue? Until a conversion mechanism like what you suggested (\currentdate[persian->day,space,month,persian->month]) is implemented, can I somehow achieve a similar result, perhaps in a not so clean way? Can one reduce the result of \currentdate to a simple number by stripping the additional stuff that is there? Similarly, can I force \currentdate to expand or is it a fundamental implementation limitation? Can I access day, month and year values in Lua, to run some if statements, etc.? For instance, if it is the first day of April, change the font of the document or something like that. —MHB On Thu, Jul 7, 2016 at 7:32 PM, Wolfgang Schuster < schuster.wolfgang@gmail.com> wrote:

1. The \currentdate command isn’t expandable and is therefore not expanded when you use it as argument for another command.

2. The \romannumerals commands expects a number as argument but \currentdate returns more than a simple number.
