Following up on my own note, I see that this fails under LMTX if compiled in a clean directory, but succeeds if first compiled with the troublesome line removed, and then, restoring the line, compiled a second time. It also works by placing a .tuc file from an older version of the document into the directory before compiling. Very strange indeed. The expected output, from one of those successful compilations:

So. I am clearly doing something wrong, but sometimes LMTX is letting me get away with it.

Hello list,

The following fails with ConTeXt  ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error       > tex error on line 6 in file G:/TestConTeXt/convert.tex: ! Incompatible glue units , pointing to the second \convertnumber line.

    \definelabel[XX]%[text=,before=,after=,alternative=inright]
    \startTEXpage[offset=2em]
     abc\XX[xx]\par
     \ref[number][xx] ·
     \convertnumber{r}{1} ·
     \convertnumber{R}{\ref[number][xx]}
    \stopTEXpage

In this case I am trying to display with roman numerals the number generated in the label created through \definelabel.

Suggestions welcomed.

the conmversion is (partly) done in lua so at some point the

  \ref[number][xx]

gets scanned which is more robust in lmtx than in mkiv

normally one does the conversion differently:

\definelabel[XX][numberconversion=R]
\definelabel[YY][XX][numberconversion=A]

\startTEXpage[offset=2em]
    1: \XX[xx]\par 2: \YY[xx]
\stopTEXpage

That generates a new labeled item albeit with a roman numeral label. I am trying to get the value of a previously generated numeric label converted roman numerals. So, consider that I have a numeric label identifying a paragraph of text. I want to reference that label in another place but need to do it in Latin.

I want to convert the original label number to a roman numeral for use in that one place, not generate a new label displayed as a roman numeral. So,

\definelabel[XX][text=¶]
\define\Naa{\ref[number][aa]}
\define[1]\Nnn{\ref[number][#1]}
\define\Raa{\convertnumber{R}{\ref[number][aa]}}
\define[1]\Rnn{\convertnumber{R}{\ref[number][#1]}}
\startTEXpage[offset=2em]
    Paragraph\XX[aa]\par
    Paragraph\XX[bb]\par
    Paragraph\XX[cc]\par
    1: \Naa\par
    2: \Nnn{bb}\par
% these fail without an existing tuc file:
    I: {\la Vide paragraphum \Raa.}\par
    II: {\la Vide paragraphum \Rnn{bb}.}
\stopTEXpage

should produce:

Paragraph ¶ 1
Paragraph ¶ 2
Paragraph ¶ 3
1: 1
2: 2
I: Vide paragraphum I.
II: Vide paragraphum II.

but this fails without an existing good tuc file. If I comment out the two latin lines, compile (to failure), and then uncomment the lines and try again, it compiles without error. Does this mean that \ref[number][label] does not really return a number as \convertnumber expects?

This is the case with today's upload as well (ConTeXt  ver: 2021.10.28 10:19 LMTX).
