I like to access mathematica from my terminal and invoke the kernel like so: jupyter-console --kernel=wolframlanguage12. It generally works well.

However, there is a persistent word wrap around ~80 characters where the output will insert a backslash, newline and indent the following line to indicate a continuation of the output, like so

In[1]: Table[n, {n, 1, 30}]
Out[2]:
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 
>   25, 26, 27, 28, 29, 30}

The wrapping happens at the same position regardless of my terminal width or FormatType. I would like to disable the text wrapping entirely. I have tried SetOptions[$Output, PageWidth -> Infinity], SetOption[InputNotebook[], LineBreakWithin -> False], and SetOptions[EvaluationNotebook[], LineBreakWithin -> False], but no change.

Does anyone know how I might disable the text wrapping when using the Wolfram kernel from jupyter console?

I have

CurrentValue[EvaluationNotebook[], FrontEndVersion]
12.0 for Linux x86 (64-bit) (April 8, 2019)

Thanks.

EDIT: SOLVED!

It was some shenanigans with WolframLanguageForJupyter which I used to install the wolframscript jupyter kernel. It had hardcoded $defaultPageWidth = 89 and used it in various request handling routines. I have substituted $defaultPageWidth = Infinity and it works, as long as I never want to set the PageWidth to something different.
