# Tablor package with metapost files generation

I want to use the tablor package but I get an issue with the compilation of the metapost file.

Here's my tableau_variation.tex file :

\documentclass{article}

\usepackage{graphicx}
\usepackage[french]{babel}
\usepackage[xcas]{tablor}

\begin{document}
\initablor
\begin{TV}
TV([-10,+infinity],[-1,1],"g","t",x^2/(x^2-1),1,n,\tv)
\end{TV}
\nettoyer
\end{document}


The compilation with pdflatex --shell-escape tableau_variation.tex fails with :

! An expression can't begin with right delimiter'.
<inserted text>
0
<to be read again>
)
l.20 beginTableau()
newLigneVariables(btex $t$ etex);val(bte $-10$ etex);
?


So I inspected the mp file created by this process : tableau_variation_Tab.mp

I replaced beginTableau() with beginTableau(0) and compiled it with mpost. The process succeded. So The .0 file was properly created.

In the tablor.sty file I can see lines with beginTableau(+nmr+). I guess this is the way the mp file is created so the number nmr is not written correctly to the mp file.
Any idea ?

• Did you read the warning on page 1 of the docs? Apparently you need an update that is not on CTAN. – Thruston Apr 7 '18 at 15:19
• Attention ! À partir de la version 4.03 de tablor, il est nécessaire d’avoir la nouvelle version de tableauVariation.mp (la 2.1 datant de décembre 2008) mais pour l’instant elle n’est pas présente sur CTAN ! Récupérez plutôt le fichier à l’adresse download.tuxfamily.org/tehessinmath/les_sources/…. – Thruston Apr 7 '18 at 15:19
• Roughly: Warning! above version 4.03 of tablor, you need the new version of tableauVariation.mp` (version 2.1 dated December 2008) but at present this file is not on CTAN. You can download the file from: download.tuxfamily.org/tehessinmath/les_sources/…. – Thruston Apr 7 '18 at 15:21
• I should have mentioned it: I've already downloaded the updated file. Its md5sum : 4294d88718cc758e33f5b944cf663ae5 So the truth is out there... – david Apr 7 '18 at 16:47
