Pandoc is a great tool to convert between various text based formats. For instance, with a single input Markdown file, I can generate an HTML page of that document, a LaTeX document, and a beautifully typeset PDF.
I had troubles installing it on Mac OSX via MacPorts; a simpler solution for me was to download and install the Haskell package and then use the commands:
This assumes, of course, that the
cabal
program that the Haskell package installs is accessible from your path.The next step for me was to install the excellent Pandoc TextMate bundle. This gives you the standard things like syntax highlighting of your document, as well as a variety of useful snippets. For instance, when I am in Pandoc mode and press ⌃ ⌥ ⌘ P, I get the following popup from which I can easily choose options via mouse or keyboard:

Before you can start using the Pandoc TextMate bundle, you must ensure that the Pandoc executable is on the PATH exposed to TextMate, which is different than your global system path. In other words, just because you can execute
pandoc
in a shell and have it work, this doesn’t mean it will work in TextMate. For instance, on my computer, Pandoc is located in:Go to TextMate -> Preferences -> Advanced -> PATH and append
:/Users/ndunn/Library/Haskell/bin
to the end of the PATH variable.Pandoc makes a few extensions to the Markdown syntax, which I really like. For instance, you can designate a section of text to be interpreted literally by surrounding it with three
~
characters. Furthermore, you can specify what language the source code is in, and the Pandoc converter will syntax highlight it in the final document (assuming the correct extensions have been installed).I like this setup because it allows you to specify the language of the block of text, which means that you can force TextMate to interpret it the same way. As I’ve blogged about previously, one can add source code syntax highlighting embedded in HTML documents. I added the following lines to my HTML language grammar in order to have a few different languages recognized and interpreted as source code within these delimited blocks.
Here is the relevant section:
(One tricky bit to get used to is that you need to have at least one blank space between surrounding text and a
~~~
delimited block, or else the ~
characters are interpreted as strikeouts through the text.)Here is a screenshot of this working in TextMate:

Finally, just to get really meta on you here’s a screenshot of the text of this document

followed by a screenshot of the PDF that LaTeX formatted via Pandoc:
I hope this has piqued your interest in Pandoc. I love the beautiful output of LaTeX but hate working with its syntax. With Pandoc I’m free to compose in Markdown, a language with a very lightweight syntax, and then convert into TeX when and if I want to.
What is it?
wkhtmltopdf
and wkhtmltoimage
are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely 'headless' and do not require a display or display service.There is also a C library, if you're into that kind of thing.
How do I use it?
- Download a precompiled binary or build from source
- Create your HTML document that you want to turn into a PDF (or image)
- Run your HTML document through the tool.
For example, if I really like the treatment Google has done to their logo today and want to capture it forever as a PDF:wkhtmltopdf http://google.com google.pdf
Additional options
That's great, I've always wanted to turn Google's homepage into a PDF, but I want a table of contents as well.
There are plenty of command line options. Check out the auto-generated wkhtmltopdf manual.

Command line tools are awesome, but I want a C library.
No problem. Check out the library documentation.
Real world examples?

Like we said, if you really like Google's homepage today and want to save it as a PDF, you could use wkhtmltopdf for that.
