SQL source code in footnotes causes PDF generation failure

[createsoftware]

The following snippet

Some text [^1]

[^1]:   More text

    ```SQL
    SQL code containing %
    ```

compiled with

pandoc minimal.md -o minimal.pdf

causes the following error message:

pandoc: Error producing PDF from TeX source.
! File ended while scanning use of \@footnotetext.
<inserted text> 
                \par 
<*> /tmp/tex2pdf21362/input.tex

!  ==> Fatal error occurred, no output PDF file produced!

The SQL and percent-sign aren't a problem -- the issue is FancyVerb in footnotes. This can be solved by putting \VerbatimFootnotes in the header:

---
header-includes: \VerbatimFootnotes
...

Some text [^1]

[^1]:   More text

    ```SQL
    SQL code containing %
    ```

@jgm, any reason this shouldn't go in the default template?

[jkr]

By the way, @createsoftware, you'll need at least 1.12 (we're on 1.13.1 now) to use the YAML metadata in the above example. But you can append that line to your default template, or use an -H / --include-in-header option on the command line.

Reproduced with latest 1.13.1.

LaTeX has problems with verbatim in footnotes. I had thought that
this problem was fixed by using fancyvrb (as we do), but apparently
you also need to but \VerbatimFootnotes in the preamble.

Pandoc should be changed so that it adds \VerbatimFootnotes to
the preamble if there are any notes containing code.

Workaround for you: create a custom template.

pandoc -D latex > default.latex
edit default.latex
# Find the line \usepackage{fancyvrb} and insert immediately after it:
# \VerbatimFootnotes
mkdir -p ~/.pandoc/templates
cp default.latex ~/.pandoc/templates/

Now pandoc will use the custom template by default.

Sorry, @jkr, just saw your reply after I replied to the OP. Should have
read further! We came to the same conclusion, and I've pushed a
fix to the default template.
