Pandoc: [WARNING] Could not convert TeX math

Question

I tried to convert html to docx by using Pandoc:
here is my html code:

<p> Example: ${v_1} = {\rm{ }}{v_2}$</p>

with MathJax config in head:

    MathJax.Hub.Config({
    extensions: ["tex2jax.js", "TeX/AMSmath.js", "TeX/AMSsymbols.js"],
    jax: ["input/TeX", "output/HTML-CSS"],
    tex2jax: {
        inlineMath: [['$', '$'], ["\(", "\)"]],
        displayMath: [['$$', '$$'], ["\[", "\]"]],
    },
    "HTML-CSS": {availableFonts: ["TeX"]}
});

Pandoc command that i used (Pandoc version 2.2.3.2):

    pandoc -s  test.html --mathjax  -f html+tex_math_dollars   --pdf-engine=xelatex  -o  xxx.docx

then i got a warning:

    [WARNING] Could not convert TeX math '{v_1} = {\rm{ }}{v_2}', rendering as TeX:
      {v_1} = {\rm{ }}{v_2}
                  ^
      unexpected "{"
      expecting "%", "\\label", "\\nonumber" or whitespace

Someone please tell me how to fix this. Thanks!

Answer 1

Use the LaTeX \textrm instead of the plain tex \rm, and pandoc will be able to handle it.

Since 7k users have viewed this question since it was asked... perhaps others have made the same mistake I made as a novice RStudio user.

The first comment in both the README.md and the README.Rmd file is

<!-- README.md is generated from README.Rmd. Please edit that file -->

The intended meaning is (at least arguably) apparent if you pay sufficient attention to the this/that relative pronouns!

<!-- You should edit the README.Rmd file, not the README.md file -->

To repair the damage... I'm currently trying the suggestion to use an explicit devtools::build_readme() which I found in RStudio README.Rmd and README.md should be both staged use 'git commit --no-verify' to override this check

No luck yet ... but I feel like I'm (finally!) making forward progress on getting $\sqrt{x}$ to display properly in my github README!
