readMarkdown Ignoring Links (in filter)

readMarkdown Ignoring Links (in filter)

[Ranjit Jhala]

[-- Attachment #1.1: Type: text/plain, Size: 1454 bytes --]

Hi,

I am writing  a small filter for converting from markdown to latex, and 
getting the odd behavior, reproduced below
via GHCi:

> Prelude Text.Pandoc.JSON Text.Pandoc> readMarkdown  def "this is 
[wiki][foo]"

Pandoc (Meta {unMeta = fromList []}) [Para [Str "this",Space,Str "is",Space,
Str "[wiki][foo]"]]


Namely, the citation `[wiki][foo]` is read as a String, and hence when 
converted 
to LaTeX rendered the wrong way (i.e. without the HREF).

I suspect I have the wrong `ReaderOptions` in `def`  -- but I don't know 
which flags to add.

I am writing this filter following the suggestion from here:

  https://groups.google.com/d/msg/pandoc-discuss/Kd1L4Rg0dx0/NZvgcMcz9NQJ

 the above only happens inside the filtered blocks -- citations of the 
above form work just fine when inside the "regular"
 unfiltered document.

Any suggestions would be most welcome!

Ranjit.

Also, I should add, everything works fine if I use the full URL instead, 
i.e. "this is [wiki](http://www.foo.com)".

Are you sure you don't mean `[wiki](foo)`?

`[wiki][foo]` will only be a Markdown link if the reference `foo` is
defined elsewhere in the document.

Yes, when I try [wiki](foo) then I get an href to "foo.pdf" which is not
what I want.

That is, "[wiki](foo)" is parsed nicely but gets rendered to the latex as
"\href{foo}{wiki}", while instead
I want it to get rendered to (the equivalent of "wiki \cite{@foo}").

Instead, what I want is to have

  "this is [wiki][foo]"

together with

  "[foo]: http://www.foo.com"

(elsewhere in the document) to be converted to a link to www.foo.com.

(Which works just fine in the main document, but not the bits that are
going through my filter...

Re: readMarkdown Ignoring Links (in filter)

[Matthew Pickering]

This is the limitation of the approach I suggested. The parsing
happens in a completely separate environment to that of the original
document.

Hi Matthew,

I think I solved the problem using a <span>...</span>. I forked and updated 
your gist to:

    https://gist.github.com/ranjitjhala/171aa922204aa84c7b3d

which seems to do the trick for me.

Thanks a lot!

Ranjit.
