Hidden Application of MMAView to an Entire Notebook

[kkoudas01]

Is it possible to automatically apply MMAView to all plots in an entire notebook, but in a hidden way so it doesn’t explicitly appear in the code?

I’m asking because I’m planning to build an educational website, and the ideal outcome would be to show only plain Mathematica code (to avoid any confusion), while still benefiting from MMAView’s behavior in the background.

Thanks in advance!

Hm... I believe from all issues you opened, the vast majority of them are compatible with Mathematica and does not feature anything from WLJS.

However, yes. It is possible by overriding StandardForm processor:

Unprotect[ToString];
ToString[expr: _[__], StandardForm] := With[{view = MMAView[expr]}, ExportString[
    StringReplace[
        (view // ToBoxes) /. {RowBox->RowBoxFlatten} // ToString
    , {"\[NoBreak]"->""}]
, "String"]];
Protect[ToString];

You can check if this code is running in WLJS by:

TrueQ[Internal`Kernel`WLJSQ]

True. It's just that these days I'm writing a notebook that deals with the styling of plots. The phenomenon often appeared where the image wouldn’t render properly, but with MMAView it worked perfectly. Therefore, there were two possibilities:

1. I frequently report minor issues (since they are simply solved with a //MMAView),
2. I apply MMAView throughout the current notebook.

With (1) I thought I would become annoying. If, however, you do need reports of these cases as well for debugging or improving WLJS, then I’d be glad to mention them.

PS: The code you provided works just fine!

(1) Sure! It helps to solve many other related issue, so the actual compatibility grows exponentially. Thank you using WLJS and helping us in improving it :)

Yeah, styling options are more limited compared to Mathematica. Then it makes sense to use MMAView for your student, who are may be more familiar with mathematica or Jupyter (that also uses the same rasterization)

I think the optimal solution is to first test them without MMAView, report any glitches, and until those are fixed, apply MMAView globally in the notebook.
