Conditional markdown parsing?

Conditional markdown parsing?

[Gabriel Volpe]

[-- Attachment #1.1: Type: text/plain, Size: 1036 bytes --]

Hi,

I'm in search of something similar to this: 
https://groups.google.com/forum/#!searchin/pandoc-discuss/conditional%7Csort:date/pandoc-discuss/R00dbPcjYRY/An6ZEYNwAgAJ

But instead, I want a specific output for LaTeX and another for EPUB (which 
goes through HTML). Basically, something like

$if(outputformat=latex)$
  \begin{foo}
  some text
  \end{foo}
$endif$

$if(outputformat=epub)$
  <div class="foo">
  some text
  </div>
$endif$

I had a look into https://pandoc.org/MANUAL.html#extension-raw_attribute but 
I'm not being able to understand how I can get this working.

Can anyone shed some light on me?

Thanks!

Or even better, can `pandoc` identify <div> blocks when parsing markdown to 
pdf and if so, apply some LaTeX style instead?

That'd be great to avoid repeating text. I should be able to just write:

 <div class="foo">
  some text
 </div>

And then have the conditional logic in my LaTeX template file.

Re: Conditional markdown parsing?

You can write a fairly simple filter that will do this for you, yes.

% cat divToEnv.lua
function Div(el)
    if FORMAT == 'latex' then
        local envname = el.classes[1]
        return {pandoc.RawBlock('latex', '\\begin{' .. envname .. '}'),
                el,
                pandoc.RawBlock('latex', '\\end{' .. envname .. '}')}
    end
end

% pandoc --lua-filter divToEnv.lua -t latex
<div class="foo">
hi there
</div>
^D
\begin{foo}

hi there

\end{foo}

% pandoc --lua-filter divToEnv.lua -t html5
<div class="foo">
hi there
</div>
^D
<div class="foo">
<p>hi there</p>
</div>

This is awesome! Thank you so much, I'll give it a try very soon.

Hi John,

This function worked very well for me but I've modified my LaTeX function
to take an extra argument and now I'm struggling to make it work:

          return {pandoc.RawBlock('latex', '\\begin{' .. class ..
'}[Some Title]'),
                  el,
                  pandoc.RawBlock('latex', '\\end{' .. class .. '}')}


This compiles but it doesn't work as I expect it to. The intended title is
rendered as part of the body instead (together with `el`). If I instead
have the LaTeX directly, it works:

                  \begin{notebox}[Custom title]

                      some content

                  \end{notebox}


Any hints?

Thanks!

Re: Conditional markdown parsing?

[John MacFarlane]

It looks like it should work.  Try using the filter but going
`-t native` to see what comes out the other end.

Thanks. Using `-t native` to generate a `.tex` file I see the following
relevant element:

,Div ("",["box","box-note"],[])
 [Para [Str "A",Space,Str "note",Space,Str "on",Space,Str
"what\8217s",Space,Str "being",Space,Str "explained"]]
,RawBlock (Format "html") "<p/>"

If I try to generate a `pdf` as usual, I get the following error: "cannot
produce pdf output from native"

I don't really understand what's going on here, to be honest ...

BTW if by any chance you're interested in FP Scala I'd be happy to give you
a copy of my work-in-progress book, where I also give credits to Pandoc
https://leanpub.com/pfp-scala/sales

Just let me know, you've been very helpful :)

Re: Conditional markdown parsing?

[John MacFarlane]

The filter does a transformation of the AST.

So if you run

pandoc --lua-filter yourfilter.lua  -t native

you'll see what it transforms it TO, and that may help
you diagnose the problem.  (With this you won't get a
tex file, you'll get a representation of a Haskell
data structure.)

Re: Conditional markdown parsing?

[Gabriel Volpe]

[-- Attachment #1: Type: text/plain, Size: 6082 bytes --]

Okay, I had to convert to LaTeX in order to find the issue:

Instead of being transformed as:


*\begin{note}[Custom Title]*

What happens is this:


*\begin{note}\[Custom Title\]*

Is this a bug?
