The only problem with Asciidoc is Windows. The a2x command uses xmllint, and therefore you must use Cygwin or a virtual machine with a Linux image. This is not what I aim for, and therefore I continued evaluating git-scribe.
This is a tool meant for writing ebooks, and it’s pretty cool unless you use it on Windows. After manually installing all its dependencies (ruby, asciidoc, xsltproc, source-highlight, apache fop), I somehow managed to generate a html book example, but the PDF generation didn’t work. The Apache FOP classes were not found, and since I’m no Ruby expert, I simply gave up and decided to try Asciidoctor.
Running on Ruby, Asciidoctor simply works like a charm. I managed to install a Ruby file watcher that automatically generates the HTML version of my markups. PDF works and the syntax doesn’t scare me a bit. There are small differences between the original AsciiDoc and the new Asciidoctor, but that’s neglectable.
