I've been using apostrophe, it shows metadata on the beginning of the file. Probably this is a new feature on Pandoc markdown.
I glanced many options but couldn't find any way to disable it.
How can I disable to printing YAML header on Markdown alongside entering this metadata which need to enter PDF info.

I want include a latex document into a markdown .md file using the YAML metadata. I have two files in a directory:
markdown.md
---
title: test fuer pdf eingeschlossen
author: AUF
keywords: test
abstract: Versuch
publish: True
include-after-body: testlatex.tex
---
A simple exampe for a test.
and testlatex.tex
some text without sense
\begin{itemize}
\tightlist
\item
firstly, a fundamental human need is;
\item
secondly, a cost-effective technical mean,
\end{itemize}
I can include the testlatex.tex file into the body of the markdown.md on the commandline with
pandoc --pdf-engine=lualatex --toc -o test.pdf markdown.md --include-after-body=testlatex.tex
but the equivalent value put into the YAML metadata seems not to have any effect (author and title are however used). I thought that the value included on the command line or in the YAML metadata would be equivalent. I checked in the pandoc latex template and see there an include for the include-after but I also wonder where the filename is converted to its content.
If I put
include-after: testlatex.tex
in the YAML metadata the name of the file is printed in the output, but the file content is not used!
Thank you for your help!
I'm having trouble permanently embedding images in my RStudio ioslides presentation.
Specifically, the problem occurs when I try to include local images via:
The images will appear successfully when I knit the document and open it directly from its folder on my computer. But if I share the html file with anyone else or copy and paste to another directory on my computer, all images embedded via  disappear.
My YAML header looks like this:
---
title: 'Title'
subtitle: 'Subtitle'
author: "Harrison"
date: '`r format(Sys.time(), "%d %B, %Y")`'
output:
ioslides_presentation:
self_contained: true
widescreen: true
smaller: true
css: custom.css
incremental: false
---
I thought that "self-contained" is supposed to accomplish what I want, that is, to create a fully self-contained html document.
Note: My images are successfully permanently embedded when I use the include_graphics() function from knitr to add a jpeg or png file.
Any idea what is going on?
I cannot reproduce your problem. Here is my reproducible example:
---
title: 'Title'
subtitle: 'Subtitle'
author: "Harrison"
date: '`r format(Sys.time(), "%d %B, %Y")`'
output:
ioslides_presentation:
self_contained: true
keep_md: true
---
## First slide
```{r, test, dev='png'}
plot(1)
```
## Second slide
`)
Both images are corrected embedded.
Please try to update your packages. If it still fails after updating all packages, please provide your xfun::session_info('rmarkdown').
Background
Pandoc's markdown lets you specify extensions for how you would like your markdown to be handled:
Markdown syntax extensions can be individually enabled or disabled by appending +EXTENSION or -EXTENSION to the format name. So, for example, markdown_strict+footnotes+definition_lists is strict markdown with footnotes and definition lists enabled, and markdown-pipe_tables+hard_line_breaks is pandoc’s markdown without pipe tables and with hard line breaks.
My specific question
For a given pandoc conversion where, say, I use grid tables in my source:
pandoc myReport.md --from markdown+pipe_tables --to latex -o myReport.pdf
How can I write a pandoc YAML block to accomplish the same thing (specifying that my source contains grid tables?)
A generalized form of my question
How can I turn extensions on and off using pandoc YAML?
Stack Overflow Questions that I don't think completely answer my question
Can I set command line arguments using the YAML metadata - This one deals with how to specify output options, but I'm trying to tell pandoc about the structure of my input
What can I control with YAML header options in pandoc? - Answerers mention pandoc's templates, but neither the latex output template nor the markdown template indicate any sort of option for grid_tables. So, it's not clear to me from these answers how knowing about the templates will help me figure out how to structure my YAML.
There may also not be a way to do this
It's always possible that pandoc isn't designed to let you specify those extensions in the YAML. Although, I'm hoping it is.
You can use Markdown Variants to do this in an Rmarkdown document. Essentially, you enter your extensions into a variant option in the YAML header block at the start of the your .Rmd file.
For example, to use grid tables, you have something like this in your YAML header block:
---
title: "Habits"
author: John Doe
date: March 22, 2005
output: md_document
variant: markdown+grid_tables
---
Then you can compile to a PDF directly in pandoc by typing in your command line something like:
pandoc yourfile.md -o yourfile.pdf
For more information on markdown variants in RStudio: http://rmarkdown.rstudio.com/markdown_document_format.html#markdown_variants
For more information on Pandoc extensions in markdown/Rmarkdown in RStudio:
http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html#pandoc_markdown
You can specify pandoc markdown extension in the yaml header using md_extension argument included in each output format.
---
title: "Your title"
output:
pdf_document:
md_extensions: +grid_tables
---
This will activate the extension. See Rmarkdown Definitive Guide for details.
Outside Rmarkdown scope, you can use Pandocomatic to it, or Paru for Ruby.
---
title: My first pandocomatic-converted document
pandocomatic_:
pandoc:
from: markdown+footnotes
to: html
...
As Merchako noted, the accepted answer is specific to rmarkdown. In, for instance, Atom md_extensions: does not work.
A more general approach would be to put the extensions in the command line options. This example works fine:
----
title: "Word document with emojis"
author: me
date: June 9, 2021
output:
word_document:
pandoc_args: ["--standalone", "--from=markdown+emoji"]
----
For people stumbling across this in or after 2021, this can be done without Rmarkdown. You can specify a YAML "defaults" file, which basically includes anything you could want to configure.
In order to do what OP wanted, all you'd need to do is
from: markdown+pipe_tables
in the defaults file, then pass it when you compile.
You can also specify the input and output files, so you can end up with the very minimal command
pandoc --defaults=defaults.yaml
and have it handle the rest for you. See https://pandoc.org/MANUAL.html#extensions for more.
Is it possible to specify in the YAML metablock a pdf header and/or footer?Something you could set to appear on every page. This is in rmarkdown and will then be rendered to a pdf (using pandoc and knitr). I have not been able to find anything (header: and footer: sadly did not work!)
---
title: testpdf | test
footer: "test footer"
theme: "zenburn"
date: "`r Sys.Date()`"
output: "pdf_document"
fig_width: 12
fig_height: 6
fig_caption: true
---
There is no native pandoc-markdown support of headers and footers. However, since pandoc generates pdf documents through latex, you can tweak your latex template to accommodate those.
Create a new template from the default one :
pandoc -D latex > footer_template.latex
Add the following lines in the latex preamble (this is a very basic example that should produce a centered footer, see the fancyhdr user manual if you need something more advanced)
$if(footer)$
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyfoot[C]{$footer$}
$endif$
Finally, add this to your document yaml header :
output:
pdf_document:
template: test.latex
Your template should either be in ~/.pandoc/templates or in the same directory as test.rmd for this to work.
