I have since then found the following additional solutions:
- Atom with asciidoc-preview
- Marked 2 - Smarter tools for smarter writers (Get the non-AppStore version for technical reasons).
- GitBook Editor
In the first 2 cases, you will also need to install asciidoctor.
Atom is my preferred every-day solution, as it uses a split window and updates automatically.
Marked 2 simply watches and automatically previews a text document which you edit in any other text editor. Getting it to work with asciidoc requires a few extra steps, and the App Store version gets in the way.
GitBook Editor should be the most satisfactory. I has gone through a few disruptive version changes, but is mostly working again. My main problems with it are that there are no line numbers, which makes editing long documents a bit of a pain, and you have no control over the styling.
It is designed to work with a free or paid
GitBook account, but it is free, and you donxe2x80x99t need use one.
