Hi all,
I use the TeX files paragraphs.tex and footnotes.tex to style the
paragraphs and footnotes in PDFs. (The input file is in pandoc-flavour
markdown.) I use them via a defaults files using "include-in-header: \n -
paragraphs.tex \n - footnotes.tex". When I convert the file to HTML, the
TeX component shows up. (It is in the <head> </head> part, before <body>,
but still shows up on the screen when I open the file.)
I've tried using the modified TeX files where I enclose them in code fences
with {=pdf} and {=latex} as well. Each time I do this, I get the error:
> Error producing PDF.
> ! LaTeX Error: Missing \begin{document}.
>

I get this same error if I try to include the headers using
"header-include:" instead of "include-in-header:".
I've tried marking the input format as "markdown+raw_attribute" and as
"markdown+raw_tex", but that doesn't change anything.
What am I doing wrong? How do I prevent the PDF/LaTeX-specific headers
from being used for outputs like HTML?
Regards,
Pranesh

Investigating using `--verbose`, I find that the intermediate file has the
"```{=latex}" / "```{=pdf}" intact:
\setcounter{secnumdepth}{5}
```{=latex}
\usepackage{microtype,parskip,bookmark,setspace,xurl,secdot}
\usepackage[hang,bottom,multiple]{footmisc}
\setlength{\footnotesep}{3mm}
```
```{=latex}
\usepackage{parskip}
\setlength{\parskip}{5pt plus1pt}
\setlength\parindent{1.5em}
```
\ifxetex
% Load polyglossia as late as possible: uses bidi with RTL langages (e.g.
Hebrew, Arabic)
This back-tick is what is causing the error.
Clearly I've done something wrong in the way I include the headers.

header-includes is the field name to use.

OK, I thought you were talking about metadata in the document,
not defaults.yaml. defaults.yaml isn't quite the same -- it
is a way of specifying default values for things you can specify
on the command line, and they work the same for the most part.
Metadata in defaults.yaml files is NOT parsed as Markdown,
but rather as plain text, just like --metadata on the command line.
This is pointed out in the documentation, which notes:
# metadata values specified here are parsed as literal
# string text, not markdown
If you want to include some metadata conditionally,
depending on the output format, but NOT by adding
header-includes to the YAML metadata in a markdown
file, then your best bet is to use a lua filter, which
has access to the output format in the FORMAT variable
and can insert the appropriate thing into header-includes
in the document's metadata.

Goodness gracious me! It's all worked out. I started using `-H` for
including the tex files some years ago not to avoid using
`header-includes`, but because I couldn't get in-file `headers-include` to
work properly. It probably wasn't working correctly back then because I
hadn't used ```{=latex}. But now, finally, this worked, when placed in the
in-file YAML metadata block:
```
header-includes: |
```{=latex}
\usepackage{microtype,parskip,bookmark,setspace,xurl,secdot}
\setlength{\parskip}{9pt plus1pt}
\setlength{\parindent}{1.5em}
\usepackage[hang,bottom,multiple]{footmisc}
\setlength{\footnotesep}{3mm}
```
```
Thanks so much John!
I think eventually I will try to learn a bit of Lua to write a filter for
this, since it's a bit ungainly to keep copy-pasting this snippet into each
document I write.
One work-around (I think, if that's the right word), which seems to work
for me:
Create a latex-headers.md with the above `header-includes` YAML metadata,
and include it as an input file (from being "markdown") in addition to your
main file. Then it seems to (a) get parsed as markdown, (b) recognized as
`headers-includes` metadata, (c) results in the LaTeX being used to create
PDFs, but not showing up in the HTML.
And thank you so much for the defaults system. It's a game-changer for the
coding-challenged amongst us.
