tex newlines in yaml metadata?

tex newlines in yaml metadata?

Hi list,

I have a latex template for yaml with a section to insert the variable
"addressee"

    $if(addressee)$
    \begin{letter}{$addressee$}
    $endif$

and then in my markdown file, I add the yaml metadata:


---
adressee: |
               Carl Boettiger
               UC Santa Cruz
               http://carlboettiger.info/
---


Where I've used the yaml block literal "|" to preserve the newlines in the
address.  Unfortunately, tex doesn't care about these newlines, since it
uses a double escape for a newline, and the address comes out as a single
line.  This presents a problem.  I try various permutations of this with
things like:

---
adressee: Carl Boettiger \\ UC Santa Cruz \\ http://carlboettiger.info/
---


but any explicit use of `\\` ends up being printed as a `\` in the tex
output pdf rather than as a newline.  How can I get newlines to work here?
 E.g. what formatting do I need to get newlines (e.g. verbatim `\\`) to
appear when pandoc parses this yaml and writes the addressee variable into
the text?

Thanks!

Carl

This is parsed as markdown.  So \\ is just an escaped \.
If you want a hard line break, use two spaces at the end of
the line, or \ followed by a newline.  Or, use a line block:

addressee: |
  | Carl B
  | UCSC
