Hi,
I can't understand why the following code does not work. Could someone
help me out here?
\starttext
\startMPpage
draw textext("\convertnumber{r}{12}");
draw textext("\convertnumber{r}{" & "12" & "}");
\stopMPpage
\stoptext
The first draw statement works perfectly. But the second one throws out
errors and complains as follows:
.....test.tex: ! Missing number, treated as zero
<to be read again>
<argument> \number "
& "12" & "
\romannumerals #1->\clf_romannumerals \numexpr #1
\relax
<argument> ... draw textext("\convertnumber {r}{" & "12" & "}
");
\meta_process_graphic ...currentMPformat }data {#1
;}initializations
{\meta_f...
\page_fitting_stop_command ...eter \c!command {#1}
\page_fitting_stop_normal
Is there a workaround here? Ultimately I want to replace "12" with a loop
variable in MetaPost.
Thanks,
~MHB

Because luatex intercepts and processes \convertnumber{r}{
and tries to pass this result to MP as a string, not the other way around.

This is quite counterintuitive... It also happens if I define a string
variable, use concatenate operator to set its value, and then finally pass
the string to textext macro.
Is there a way to get around this issue?
