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

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

[Pablo Rodriguez via ntg-context]

Dear list,

I would like to get the current month in Roman numerals (just now, it
would be XII for December).

The best I get is:

  \currentdate[\cldcontext{converters['R']
   (tonumber(os.date("\letterpercent m", os.date(os.time()))))}]

This strikes me as too complex (even for someone who cannot code).

Is there now simpler way to write that?

Just in case it may be relevant, this is part of the full day reference.

Many thanks for your help,

Pablo

The \date (and \currentdate) command supports number conversion for the 
day and year values but not the month.

\starttext
\currentdate[d:R,space,space,y:R]
\stoptext

The simplest method is to use \convertnumber in combination with 
\normalmonth etc. which holds the value for the current month etc.

\starttext
\convertnumber{R}{\normalday  }\textslash
\convertnumber{R}{\normalmonth}\textslash
\convertnumber{R}{\normalyear }
\stoptext

Many thanks for your fast reply, Wolfgang.

I didn’t even know that there were such short invocations for number
conversions in \currentdate.

First time I see these commands. Good to know them.

Many thanks for your help,

Pablo
