@deepsymmetry/asciidoctor-bytefield

asciidoctor-bytefield

Asciidoctor.js extension to render byte field diagrams as SVG.

This allows you to invoke bytefield-svg to create a byte field diagram within an AsciiDoc document by simply creating a bytefield block:

[bytefield]
----
(draw-column-headers)
(draw-box 0x0f)
...
----

The Clojure-based domain specific language in which you write your diagrams has its own documentation site.

Use with Node.js

Install the dependencies:

npm install asciidoctor @deepsymmetry/asciidoctor-bytefield

Create a file convert.js with the following content:

const asciidoctor = require('asciidoctor')();
const registry = asciidoctor.Extensions.create();

require('@deepsymmetry/asciidoctor-bytefield')(registry);

const html = asciidoctor.convertFile('sample.adoc', {
  to_file: false,
  extension_registry: registry
});
console.log(html);

Create a file sample.adoc with content similar to this:

# Some Document

Here is a paragraph.

.A byte field
[bytefield]
----
(draw-column-headers)
(draw-box 42)
(draw-gap "Whee!")
(draw-bottom)
----

And some more text.

Run the script to render the document:

node convert.js >sample.html

Use with Antora

Install the module:

npm install @deepsymmetry/asciidoctor-bytefield

Register the extension in your Antora playbook:

asciidoc:
  extensions:
    - @deepsymmetry/asciidoctor-bytefield
