HOW-TO: Compiling the Cgreen Guide
===================================
The Cgreen Guide Book is written using Asciidoctor. Asciidoctor builds
upon the asciidoc format, is 100 times faster than the Python asciidoc
toolchain and can generate PDF in the same step. Writing in
asciidoc(tor) is a wonderful way to write textual docs. Please visit
http://www.asciidoctor.org for more information.
You also need a source-highlighter as described in
(http://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#source-code)
There are a number of source examples in the documentation that are
automatically included from the `tutorial_src` subdirectory. They are
kept separate so that they can be compiled to ensure that they
actually are correct. Then all, or a part of, the file can be
included. To do that, go to the subdirectory, ensure you have the
correct version of cgreen in your path and do `make`.
The one drawback of this strategy is that you cannot read the source
of the examples in a raw asciidoc-conversion, like on github, since it
requires including other files, which is not allowed for security
reasons. So we need to generate the documentation and upload it to
`cgreen-devs.github.io`. Ensure you have *asciidoctor* installed
(`sudo apt install asciidoctor` or similar).
It is preferred to generate multi-page HTML, which currently
asciidoctor does not do natively yet. There is an extension in the
asciidoctor-extension-lab, which I have not
tried. [asciidoctor-chunker](https://github.com/wshito/asciidoctor-chunker)
works well, but requires installing Roswell (a Common Lisp
environment). If you use asciidoctor-chunker, first generate the HTML with asciidoctor
asciidoctor cgreen-guide-en.asciidoc -o html/cgreen-guide-en.html
then chunk it using asciidoctor-chunker (assuming some convenience
links in your path...)
