TemplateBox with RowDefault tag is unsupported

vsht commented 4 years ago

It appears that a TemplateBox containing a "RowDefault" tag cannot be processed properly. Cf. e.g. this typesetting code from https://mathematica.stackexchange.com/questions/174627/writing-partial-differentiation-in-a-subscript/174630#174630

Derivative /: MakeBoxes[
    Derivative[n_Integer?NonNegative, m_Integer?NonNegative][f_], form_
] := SubscriptBox[
    MakeBoxes[f, form],
    TemplateBox[Join[ConstantArray["x", n], ConstantArray["y", m]],"RowDefault"]
]

When trying to apply CellToTeX to

Derivative[1, 0][f][x, y]

as in

CellToTeX[
 Cell[BoxData[
   FormBox[RowBox[{SubscriptBox["f", 
       TemplateBox[{"x"}, "RowDefault"]], "(", 
      RowBox[{"x", ",", "y"}], ")"}], TraditionalForm]], "Output"]]

the function fails.

According to

https://mathematica.stackexchange.com/questions/55363/incompatibility-of-row-and-texform/182382#182382

"RowDefault" was introduced in Mma 9. Indeed I can workaround the issue if I generate my cells in Mma 8, where no such tags arise.

Similarly to linked answer, workaround for this problem is to replace internal function, used by CellsToTeXto convert TemplateBoxes, with builtin one:

CellsToTeX`Internal`templateBoxDisplayBoxes = BoxForm`TemplateBoxToDisplayBoxes;

I guess I was not aware of existence of BoxForm`TemplateBoxToDisplayBoxes function, when I started this package, so I created my own imperfect version.

Great, many thanks for this fix. I really appreciate all your work on this package. Over the years it saved me a lot time in getting MMa output into LaTeX.

BTW, what would be the preferred way to cite CellsToTeX in a publication? Is there perhaps a Zenodo-DOI ? https://guides.github.com/activities/citable-code/
