I wrote about Pandoc last year, but I’m using it more and more and I’ve found myself editing the original post a fair few times. This is the updated 2016 version that gathers together useful commands I’ve learned so far.
Last year I found myself needing to do a lot of document conversion, and maintaining documentation that needs to be available in a variety of formats (HTML, Word documents, Markdown and PDF). My tool of choice for this sort of thing is Pandoc, which is available for Windows, Mac OS X and Linux, although most of my usage so far has been on Linux and Mac OS X (it’s a command line package that can output to Dropbox, so it doesn’t matter where it runs really).
There are instructions for installing Pandoc on quite a few platforms. I’ve found that following these is generally enough, although it’s worth installing the latest version of the .deb packages rather than the one in the repositories.
On Debian/Ubuntu I also add the
texlive-latex-extra package, but that’s largely because it gives me a specific Beamer theme I like to use.
If you’re using Pandoc on Mac OS X there is one more command you’ll need to issue prior to the first time you want to create a PDF file:
sudo ln -s /Library/TeX/texbin/pdflatex /usr/local/bin/
This will ensure Pandoc knows where to find pdflatex. If this step isn’t followed then you’ll likely get an error message along the lines of
pandoc: pdflatex not found. pdflatex is needed for pdf output.
Pandoc works for me because I write everything in markdown, and Pandoc is great at taking markdown and converting it into almost anything else. It’s also good if you need to create a PDF, a Word document and a slide show from the same document. The syntax is fairly simple for most document types:
pandoc input.md -s -o output.docx pandoc input.md -s -o output.html pandoc input.md -s -o output.epub
Conversion to PDF works the same, although I’m not a fan of wide margins, so I tweak it slightly:
pandoc -V geometry:margin=1in input.md -s -o output.pdf
For a Beamer slide show you’ll need something like:
pandoc -t beamer input.md -V theme:metropolis -o output.pdf
Pandoc does a lot more, but the documentation is great, and the commands above should be enough to get you started. If you want to try out the functionality in a web browser then http://pandoc.org/try/ should be able to handle most types of conversions.
