[NTG-context] Re: month form \currentdate in Roman numerals

BTW why doesn't \setuplabeltext exist in the mtx-server-ctx-help? It does exist in setup-en.pdf and shows that it is an instance of \setupLABELtext. On Fri, Feb 28, 2025 at 5:28 PM Mohammad Hossein Bateni wrote:

the following outputs "farsi" instead of "fa". is this the reason the translation of jalali month does not kick in?

------ \mainlanguage[fa] \currentlanguage ------

strangely either of the following two lines changes the month name.

------ \setuplabeltext[en][february:jalali=test] \setuplabeltext[fa][february:jalali=test] \currentlanguage[month:jalali] ------

I'm confused. why isn't the data in lang-txt.lua used? strangely, the following outputs the correct translation of second jalali month in farsi regardless of the above \setuplabeltext commands:

---- \ctxlua{context(languages.data.labels.texts['february:jalali'].labels.fa)} ----

For Jalali dates and Persian numbering, I can get the following to work:

\persiandecimals{\rawdate[jalali:to,d]}/\persiandecimals{\rawdate[jalali:to,M]}/\persiandecimals{\rawdate[jalali:to,y]}

but the following does not work and throws an error:

\persiandecimals{\currentdate[jalali:to,d]}

If I want to get the output for different date, option 2 below works and option 1 does not.

--------- % option 1 \persiandecimals{\begingroup\setdate[m=5]\rawdate[jalali:to,y]\endgroup} % option 2 {\begingroup\setdate[m=5]\persiandecimals{\rawdate[jalali:to,y]}\endgroup} ----------

does \setdate expand to something non-empty?

note that with the above ideas, we cannot get "mm" with leading zeros to work because \persiandecimals drops the leading zero. the following ugly hack works if I insist on using \currentdate to format the output and I want Indic digits.

-------- \startluacode function persmap(s) local stream = tostring(s) local mapping = languages.decimals.persian local gsub = string.gsub return mapping and gsub(stream, ".", mapping) or stream end \stopluacode

\def\persmap#1{\ctxlua{context(persmap("#1"))}} \def\mycurrentdate[#1]{\persmap{\rawdate[#1]}} \mycurrentdate[jalali:to,dd,/,mm,/,y] --------

even with \mainlanguage[fa] and \language[fa] I don't get the month names translated to persian labels. why?

------ \mainlanguage[fa] \language[fa] \starttext \currentdate[month:jalali] \stoptext -----

Any thoughts why the following doesn't work?

\currentdate[d:persiannumerals]

It just outputs the normal digits.

In contrast, these work:

\currentdate[d:abjadnumerals] \convertnumber{persiannumerals}{\normalday}

persiannumerals aren't considered a conversion method for the underlying Lua mechanism while there exists a method for \convertnumber on the TeX side.

Both system are separate (to a certain degree) but the TeX side borrows the conversion vectors from the Lua mechanism.
