Math functions not typeset inside MetaPost

Math functions not typeset inside MetaPost

Hi Hans,

[I am sending this again since the previous mails regarding were sent during 
the weekend].

I am on the most recent upload of LMTX [2022.04.15 20:20]. However, when I try 
to use math functions inside MetaPost strings, the function is not typeset 
correctly. Please consider the following MWE:

  \starttext
    \startMPcode
    draw textext("\m{\max_i x_i}");
    \stopMPcode
  \stoptext

which produces the output attached here as an image. Instead of the mfunction 
maxᵢ xᵢ 
some form of the string mathfunctionhandlelabel is typeset.

I tried to inspect \math_function_handle_label [math-ini] and also mp-mlib and 
mlib-pps but could not figure out what is going wrong. I wonder if there is a 
backslash missing somewhere. I am a little worried since I use MetaFun in 
conjunction with maths and could not figure out what the issue is.

Please see the original post by Dalyoung here:

Please advise.

Thank you,
  Sreeram

Thanks, this will be fixed in the next upload (that will take place
soon as far as I've heard).

Best regards, Mikael

Thanks very much for the quick reply. Yes: it is fixed in the latest upload 
just now.
