I try make a table with some random numbers but I found a problem with this
code:


\starttext
\ctxluacode{v=math.random(400,600)/10;context("%0.1f",v) ;}

\bTABLE
\bTR\bTD Distance (cm) \eTD\bTD $\Delta t$ (s) \eTD\eTR
\bTR\bTD[nr=3]  \ctxluacode{v=math.random(400,600)/10;context("%0.1f",v) ;}
 \eTD\bTD t1 \eTD\eTR
\bTR\bTD t2 \eTD\eTR
\bTR\bTD t3 \eTD\eTR
\eTABLE


\stoptext

\ctxluacode{v=math.random(400,600)/10;context("%0.1f",v) ;}   don't work
inside the bTABLE environment.

Thanks in advance.

Jorge

just wrap the code in a macro. Lua code needs a different catcode
regime and expansion rules that don’t cooperate well with the
table scanner. E.g.

    \startluacode
      local mathrandom = math.random
      local context    = context
      document.get_random_number = function ()
        context ("%0.1f", mathrandom (400, 600) / 10)
      end
    \stopluacode

    \def \getrandomnumber {\ctxluacode {document.get_random_number ()}}

    \starttext
      \bTABLE
        \bTR \bTD Distance (cm)          \eTD \bTD $\Delta t$ (s) \eTD \eTR
        \bTR \bTD[nr=3] \getrandomnumber \eTD \bTD t1             \eTD \eTR
        \bTR                                  \bTD t2             \eTD \eTR
        \bTR                                  \bTD t3             \eTD \eTR
      \eTABLE
    \stoptext

Is there a way to pass arguments to getrandomnumber() function?

\startluacode
      local mathrandom = math.random
      local context    = context
      document.get_random_number = function (min,max,delta)
        context ("%0.1f", mathrandom (min, max) / decimal)
      end
    \stopluacode

    \def \getrandomnumber#1#2#3 {\ctxluacode {document.get_random_number
(#1,#2,#3)}}

    \starttext
      \bTABLE
        \bTR \bTD Distance (cm)          \eTD \bTD $\Delta t$ (s) \eTD \eTR
        \bTR \bTD[nr=3] \getrandomnumber{34,56,10} \eTD \bTD t1
\eTD \eTR
        \bTR                                  \bTD t2             \eTD \eTR

Or define it monadic:

  \def \getrandomnumber #1{\ctxluacode {document.get_random_number (#1)}}

Now you can use your original syntax:

  \getrandomnumber {23, 42, 10}

Though it blurs the line between TeX and Lua code.

Best,
Philipp
