Remove minted from Latex base template

[takluyver]

It requires a flag to disable a security feature, which we've decided not to use.

Closes gh-350

Alternative to #353

This then "reopens" #335

irkernel/repr right now depends on minted: https://github.com/IRkernel/repr/blob/master/R/repr_function.r#L37 (this is not in then PR in IRkernel/repr#77 which only switches the default to use a r function to highlight)

[takluyver]

Right, it effectively pushes the issue back to IRkernel.

it is. i think you misinterpret the code.

repr_latex.function calls repr_function_generic(..., high_wrap = '%s', norm_wrap = minted_wrap, ...), and if highlight == TRUE, the function uses high_wrap instead of norm_wrap. i.e. minted isn’t used.

if we merge IRkernel/repr#77, we have a default that works, and once somebody changes the option, they’ll have to go the route jupyter nbconvert --to=text *.ipynb; pdflatex -shell-escape *.tex

merging both PRs would be the pragmatic solution that “makes the ‘download PDF’ button work”

Merging this because the test failure emails are getting old, and this failure might be obscuring other failures. I think we have agreement on this, but if we want to do something else, we can always change it later.
