Transform a fenced div to mkdocs markdown admonition format

Transform a fenced div to mkdocs markdown admonition format

[Aidan Reilly]

[-- Attachment #1.1: Type: text/plain, Size: 932 bytes --]

Hello!

Trying to figure out how to use pandoc +fenced_div with a filter to 
transform this:

::: note
Here is the first line of this note.

And the second,

And the third!
:::

into this:

!!! note
    Here is the first line of this note.

    And the second,

    And the third!

Struggling to understand if it is possible to "indent" elements using 
pandoc. The mkdocs markdown spec requires the body of notes to be indented 
by 4 spaces.  Is there a way to apply indents without stringifying the 
content?

Thanks!

[John MacFarlane]

I assume you’re targeting markdown?

You could then just create a RawBlock with format “markdown”, and put this content in it with whatever indentation you like.

Re: Transform a fenced div to mkdocs markdown admonition format

[Aidan Reilly]

[-- Attachment #1: Type: text/plain, Size: 3570 bytes --]

Something like this copied from https://jmablog.com/post/pandoc-filters/?
My problem is understanding how to add the required indent to every line in
the `elem` - If I stringify, I lose the markup (backticks, etc) in the
content.

function Div (elem)
  if FORMAT:match 'latex' then
    if elem.classes[1] == "notes" then
      return {
        pandoc.RawBlock('latex',
'\\begin{tcolorbox}[colframe=Apricot!20!white,
colback=Apricot!8!white]'),
        elem,
        pandoc.RawBlock('latex', '\\end{tcolorbox}')
      }
    else
      return elem
    end
  end
end

Re: Transform a fenced div to mkdocs markdown admonition format

[Albert Krewinkel]

You could try with `pandoc.write`. Probably something along the lines of

``` lua
local md = pandoc.write(pandoc.Pandoc(div.contents), 'markdown')
return md:gsub('\n', '    \n')
```

(untested)

Re: Transform a fenced div to mkdocs markdown admonition format

[Aidan Reilly]

[-- Attachment #1: Type: text/plain, Size: 6228 bytes --]

Trying this, but it's just passing the text of the admonition block through:

local stringify = (require 'pandoc.utils').stringify

local admonitions = {
  warning   = {pandoc.Str("!!! warning")},
  note      = {pandoc.Str("!!! note")},
  tip       = {pandoc.Str("!!! tip")},
  important = {pandoc.Str("!!! important")},
  caution   = {pandoc.Str("!!! caution")}
  }

function Writer (doc, opts)
  local filter = {
    Div = function (el)
      local admonition_text = admonitions[el.classes[1]]
      if admonition_text then
        table.insert(el.content, 1,
            pandoc.Para{ pandoc.Str(stringify(admonition_text)) })
        local md = pandoc.write(pandoc.Pandoc(el.content), 'markdown')
        return pandoc.RawBlock('markdown', md):gsub('\n', '    \n')
      end
    end
  }
  return pandoc.write(doc:walk(filter), 'markdown', opts)
end

Re: Transform a fenced div to mkdocs markdown admonition format

The order of spaces and newline in the replacement was switched. After
some playing around, this is the filter I came up with:

``` lua
local admonitions = {
  warning   = '!!! warning',
  note      = '!!! note',
  tip       = '!!! tip',
  important = '!!! important',
  caution   = '!!! caution'
}

local opts = PANDOC_WRITER_OPTIONS -- reuse options to render snippets
opts.columns = opts.columns - 4    -- admons are indented by four spaces
opts.template = nil                -- render a snippet

function Div (div)
  local admonition_text = admonitions[div.classes[1]]
  if not admonition_text then return nil end  -- not an admonition: bail

  local md = admonition_text .. '\n' ..
    pandoc.write(pandoc.Pandoc(div.content), 'markdown', opts)
  return pandoc.RawBlock(
    'markdown',
    md:gsub('\n*$', '')     -- remove trailing newlines
      :gsub('\n', '\n    ') -- indent block
  )
end
```

Thanks Albert!

I really appreciate you looking at this. When I run the above, I get this
error:

Error running filter admonitions.lua:
admonitions.lua:10: attempt to index a nil value (local 'opts')
stack traceback:
admonitions.lua:10: in main chunk

Do I need to specify something in the command line? I'm running the build
like so:

asciidoctor -b docbook -o - $PAGE | pandoc  --markdown-headings=atx
--shift-heading-level-by=1 --wrap=none -t markdown+backtick_code_blocks
--lua-filter=admonitions.lua -f docbook - > ./docs/$PAGE.md

Oh I guess I need to configure https://github.com/pandoc/lua-filters ?

The most likely cause for this is an older pandoc version. The
`PANDOC_WRITER_OPTIONS` global was introduced in pandoc 2.17.

The filter can be made more robust by replacing line 9 with

```lua
local opts = PANDOC_WRITER_OPTIONS or {columns = 72}
```

That will ensure that the filter works even with older pandoc versions
(but with reduced functionality in that case).

That did it Albert - thank you! I need to spend a bit more time brushing up
on Lua I think.
