帮助使用 Lua 过滤器通过 Pandoc 将 markdown 转换为 LaTeX

Question

在 markdown（用 Obsidian.md 编写）中，我使用插件/主题，以便*==text==*将其呈现为红色而不是斜体并突出显示。

我使用这个 lua-filter 将常规转换==highlighting==为 LaTeX \hl{highlighting}，效果很好:(我不知何故需要这两个文件，我不记得为什么） 突出显示.lua：

    --[[
    Add support for a custom inline syntax.
    This pandoc Lua filter allows to add a custom markup syntax
    extension. It is designed to be adjustable; it should not be
    necessary to modify the code below the separator line.
    The example here allows to add highlighted text by enclosing the
    text with `==` on each side. Pandoc supports this for HTML output
    out of the box. Other outputs will need additional filters.

    -- Lua pattern matching the opening markup string.
    local opening = [[==]]
    
    -- Lua pattern matching the closing markup string.
    local closing = [[==]]
    
    -- Toggle whether the opening markup may be followed by whitespace.
    local nospace = true
    
    -- Function converting the enclosed inlines to their internal pandoc
    -- representation.
    local function markup_inlines (inlines)
      return pandoc.Span(inlines, {class="mark"})
    end
    
    ------------------------------------------------------------------------
    
    local function is_space (inline)
      return inline and
        (inline.t == 'Space' or
         inline.t == 'LineBreak' or
         inline.t == 'SoftBreak')
    end
    
    function Inlines (inlines)
      local result = pandoc.Inlines{}
      local markup = nil
      local start = nil
      for i, inline in ipairs(inlines) do
        if inline.tag == 'Str' then
          if not markup then
            local first = inline.text:match('^' .. opening .. '(.*)')
            if first then
              start = inline -- keep element around in case the
                             -- markup is not closed. Check if the
                             -- closing pattern is already in this
                             -- string.
              local selfclosing = first:match('(.*)' .. closing .. '$')
              if selfclosing then
                result:insert(markup_inlines{pandoc.Str(selfclosing)})
              elseif nospace and first == '' and is_space(inlines[i+1]) then
                -- the opening pattern is followed by a space, but the
                -- config disallows this.
                result:insert(inline)
              else
                markup = pandoc.Inlines{pandoc.Str(first)}
              end
            else
              result:insert(inline)
            end
          else
            local last = inline.text:match('(.*)' .. closing .. '$')
            if last then
              markup:insert(pandoc.Str(last))
              result:insert(markup_inlines(markup))
              markup = nil
            else
              markup:insert(inline)
            end
          end
        else
          local acc = markup or result
          acc:insert(inline)
        end
      end
    
      -- keep unterminated markup
      if markup then
        markup:remove(1) -- the stripped-down first element
        result:insert(start)
        result:extend(markup)
      end
      return result
    end
    
    local function markup_inlines (inlines)   return {pandoc.RawInline('tex', '\\hl{')} .. inlines .. {pandoc.RawInline('tex', '}')} end

跨度：

    function Span (span)
      if span.classes:includes 'mark' then
        return {pandoc.RawInline('latex', '\\hl{')} ..
          span.content ..
          {pandoc.RawInline('latex', '}')}
      end
    end

这很好用，我在这里得到了它：https://gist.github.com/tarleb/a0646da1834318d4f71a780edaf9f870

然而，对于我的其他用例，我希望它能够呈现*==this kind of highlighting==*为\colorbox{lightred}{this new kind}

我尝试用 替换\\hl{但\colorbox{declared-color}{没有效果。

我想知道这是否与课程有关？但将该课程从 重命名mark为mark-red也不起作用。

这是我的Latex 分子动力学：

% Options for packages loaded elsewhere
\PassOptionsToPackage{unicode}{hyperref}
\PassOptionsToPackage{hyphens}{url}
%
\documentclass[a4paper, 12pt, oneside]{article}
\usepackage[a4paper, portrait, margin=1in]{geometry}


\begin{document}


Lorem or whatever.


    $body$ 

\end{document}

我使用这个作为模板将 Markdown 转换为 LaTeX，并用来$body$自我的 Markdown 文件的文本替换。

我如何转换*==this==*为\colorbox{lightred}{this}？

有什么建议或想法吗？谢谢！
