Set margin size when converting from Markdown to PDF with pa

Answer 1

You'll need to use a custom LaTeX template. First, use pandoc to create a copy of the default template:

pandoc -D latex > mytemplate.latex

Now edit this template. Somewhere in the preamble (between \documentclass{...} and \begin{document}), insert the lines

\usepackage{setspace}
\doublespacing

Then, to use your custom template:

pandoc --template mytemplate.latex mypaper.txt -o mypaper.tex
