GDPRTreeProcessor

gdpr-tree-processor.js

module.exports = function (registry) {
  registry.treeProcessor(function () {
    var self = this
    self.process(function (doc) {
      doc.getBlocks()[0] = self.createBlock(doc, 'paragraph', 'GDPR compliant :)')
      return doc
    })
  })
}

使用

const asciidoctor = require('asciidoctor')()
const registry = asciidoctor.Extensions.create()
require('./gdpr-tree-processor.js')(registry)

const doc = asciidoctor.convertFile('sample-gdpr-doc.adoc', { 'extension_registry': registry })
console.log(doc.getBlocks()[0].getSource()) // 'GDPR compliant :)'
