hello
i am converting md to epub file but that md file is programming book where 
is some codes written inside but when i convert it to epub then its auto 
detecting these tags and making very bad epub file with page breaks and 
some other kind of coding elements

for example i attached screenshot and point out with red mark
kindly check attach file

there is any option to ignore programming codes while converting to epub 
file ?



Thanks

Note that Markdown allows you to include HTML elements, so whenever you write e.g. <h1> directly, Pandoc assums that's what you're doing and will put an <h1> tag in the html (or epub) output.

You'll want to mark the tags as code, which you can do with backticks: `<h1>`.

so before convert to epub file i have to edit md file and find all tags and 
add these backticks ? 
there is no option in pandoc to ignore tags inside book ?

If you simply want to ignore all raw HTML elements then I think that a lua
filter that ignores all RawInlines (perhaps only those with format="html")
will work for you. But if some HTML elements need to retain their HTML
meaning then more logic will be needed. For example, this document:

% cat raw.md
This is <b>bold</b> text.

gives this HTML:

% pandoc raw.md
<p>This is <b>bold</b> text.</p>

...but with this filter:

% cat raw.lua
function RawInline(raw)
  if (raw.format == 'html') then
    return {}
  end
end

...it gives this:

% pandoc raw.md -L raw.lua
<p>This is bold text.</p>

This filter will convert all raw HTML to code in backticks, with syntax
highlighting. Save it as raw2code.lua and include --lua-filter=raw2code.lua
on the pandoc command line.

local code_for = {
  RawInline = pandoc.Code,
  RawBlock = pandoc.CodeBlock
}
local function raw2code (elem)
  if 'html' == elem.format then
    return code_for[elem.tag](elem.text, { class = 'html' })
  end
  return nil
end
return {
  {
    RawInline = raw2code,
    RawBlock = raw2code
  }
}

Re: tagging codes detecting

This is probably because Pandoc expects text between dollar signs `$...$`
and
`$$...$$` to be TeX math and fails to interpret some text which ended up
between two dollar signs as such.

<https://pandoc.org/MANUAL.html#extension-tex_math_dollars>

Alternatively it may be that pandoc expects text between backslash escaped
parentheses `\(...\)`/`\\(...\\)` or square brackets `\[...\]`/`\\[...\']`
to be
TeX math, but I believe those extensions are not enabled by default.

<https://pandoc.org/MANUAL.html#extension-tex_math_single_backslash>

<https://pandoc.org/MANUAL.html#extension-tex_math_double_backslash>

In this case the solution, unless you intended to include TeX math somewhere
in your document, is to disable those extensions by including

    -f
markdown-tex_math_dollars-tex_math_single_backslash-tex_math_double_backslash

in your pandoc command line, or modifying any existing --from, -f,
--read or -r option accordingly.

Yet another alternative may be that you have TeX code in your document which
needs to be marked as code. For that a slightly modified filter provides a
solution:

local format2class = {
  html = 'html',
  tex = 'latex',
  latex = 'latex'
}
local code_for = {
  RawInline = pandoc.Code,
  RawBlock = pandoc.CodeBlock
}
local function raw2code (elem)
  local class = format2class[elem.format]
  if class then
    return code_for[elem.tag](elem.text, { class = class })
  end
  return nil
end
return {
  {
    RawInline = raw2code,
    RawBlock = raw2code
  }
}

Re: tagging codes detecting

[mr vicky]

[-- Attachment #1.1: Type: text/plain, Size: 10824 bytes --]

@BP
so i have to create .lua file with this code and point out lua file in 
command line ?
by the way i used --webtex in command and its convert epub without any 
error but i dont know for what purpose pandoc using --webtex command
may be it is ignoring those type characters or may be i am wrong about that

Error running filter raw2code2.lua:
