Accessing custom jbake confing properties in asciidoc

Question

After some time I spent staring at the jbake code, I figured out that if I declare my own property in jbake.properties :

...
foo=bar
...

I can reuse that in files that go through a template engine by referencing it as ${config.foo}. I'd like to have this substitution working also on the content lvl, i.e. for files written in asciidoc, living inside the content directory.

Is there any non-trivial way to achieve it? How can I make the templating engine to proccess the result of asciidoc parses engine, or make it running it before the asciidoctor?

Answer 1

I found the answer myself. To use the property substitution in asciidoc files, add following to the jbake.properties:

...
asciidoctor.attributes.export=true
foo=world
...

and reference the variable in aFile.adoc this way:

Hello {foo}!
