recent versions of newtxmath define widebar, breaking scribble output

[bremner]

The following LaTeX document is reduced from what scribble generates from a hello world document. With newtxmath.sty 1.7 (2021/12/18), it generates an error because \widebar is already defined. Uncomenting the let for widebar seems to "fix" it, no idea if that's the best approach.

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathabx}
\let\widering=\relax
%\let\widebar=\relax
\usepackage{newtxmath}
\begin{document}
hello world
\end{document}

Here's the scribble document.

#lang scribble/base
@(require scribble/core
          scribble/manual)

hello world

I don't know of a way to remove commands in the latex prefix.

The best work around I can think of: copy the math-prefix.tex file and delete the offending line. Then use:

 scribble --prefix math-prefix.tex   file.tex

A while back @rfindler posted the following:

#lang scribble/base
@(require (only-in scribble/core make-style)
          (only-in scribble/latex-properties latex-defaults+replacements))

@(define my-style
   (make-style
    #f
    (list (latex-defaults+replacements
           (list 'collects #"scribble" #"scribble-prefix.tex")
           (list 'collects #"scribble" #"scribble-style.tex")
           '()
           (hash "scribble-load-replace.tex" #"\\renewcommand{\\packageMathabx}{\\relax}\n")))))

@title[#:style my-style]{Discourse}

It should help.

[rfindler]

Yeah, we should really go clean up that part of the docs and maybe make some changes to scribble itself to make this sort of thing easier to find and to accomplish!

Maybe I misunderstand, but the existing prelude is full of workarounds for problems of this type.

    \newcommand{\packageWasysym}{
      \let\leftmoon\relax \let\rightmoon\relax \let\fullmoon\relax \let\newmoon\relax \let\diameter\relax
      \usepackage[nointegrals]{wasysym}}

    \newcommand{\packageTxfonts}{
      \let\widering\relax
      % insert "\let\widebar\relax" here
      \usepackage{newtxmath}}

It seems like we just need one more?

I wasn't clear. I was thinking of a here-and-now solution that works without changing the default prelude.
