DocuOps: Documentation is an engineering problem.
5 . 1

6.
Go from writing to publication in near-zero effort.
5 . 2

7.
Reduce manual proof reading to absolute minimum that is still sensible.
5 . 3

8.
Reduce the dev-doc distance
5 . 4

9.
Focus on content, not formatting
5 . 5

10.
Write-once, publish multiple formats
5 . 6

11.
Prefer text-based markup
5 . 7

12.
DocuOps is not restricted to technical documents.

ASCIIDOCTOR

15.
ASCIIDOCTOR
Written in Ruby
Runs as AsciidoctorJ via JRuby
Runs as Asciidocto.js via Opal transpilation.
Standard backends: HTML, Docbook5, PDF, EPUB.
8

16.
ASCIIDOCTORJ 2.1.0RELEASED
Fully separate API from implementation engine.
Default JRuby engine is Ruby Asciidoctor 2.0
Binary incompatible with AsciidoctorJ 1.6.x
Extensions will need to be recompiled.
9 . 1

17.
PLUGGABLE SYNTAX HIGHLIGHTERS
Supports CodeRay, Pygments, Highlight.js, Prettify & Rouge
Includes dark pygment styles
highlightjs-languages attribute
9 . 2

18.
CONVERTER API
Easier to register and implement a new backend converter.
Bridging APIs for legacy converters.
Built-in converters can be extended.
9 . 3

19.
NICETIES
Asciidoctorj installed via SDKman.
Asciidoctor cheatsheet via asciidoctor(j) --help
Delegate unregistered backends

USING ASCIIDOCTOR WITH MAVEN
pom.xml
Sources go in ${basedir}/src/main/asciidoc. Output goes to
${project.build.directory}/generated-docs.
<plugins>
<plugin>
<groupId>org.asciidoctor</groupId>
<artifactId>asciidoctor-maven-plugin</artifactId>
<version>1.5.8</version>
...
</plugin>
</plugins>
10 . 1

21.
USING ASCIIDOC FOR MAVEN SITE
Place documents in src/site/asciidoc.
Runs independently from src/main/asciidoc.
10 . 2

22.
Gradle is more than a tool for building Java/Groovy/Kotlin etc.
It is an advanced pipeline automation tool.
11

23.
Asciidoctor plugin for Gradle is (probably) the most advanced integration
between build tooling and documentation production.
12

24.
STATE OF ASCIIDOCTOR GRADLE PLUGINS
v1.5.x & v1.6.x in maintenance
v2.1.0 released
v2.2.0 in progress
v3.0.0 in development
13

25.
LEGACY: 1.5.X / 1.6.X
Latest releases 1.5.12 & 1.6.1.
Now uses external Java process to build.
Urgent maintenance xes only.
Not guaranteed to work with Gradle 5.0+
Uses AsciidoctorJ 1.5.x/1.6.x as engine
14

26.
2.0.0
Complete redesign.
Some backwards compatibility.
Requires Gradle 4.0+.
Groovy DSL & Kotlin DSL.
7 subprojects & 10 plugins.
(1.5.x: 1 project & 2 plugins).
Will probably support Asciidoctor.js in future.

39.
TASK CONFIGURATION
Learning from the past all Asciidoctor tasks have an extended set of DSL
con guration options.
17 . 1

40.
SOURCES
Sources are always speci ed relative to a source root.
asciidoctor {
sourceDir 'src/docs/asciidoc'
sources {
include 'index.adoc'
}
}
17 . 2

41.
OUTPUT
Specify where outputs will be written to.
asciidoctor {
outputDir "${buildDir}/docs"
}
17 . 3

42.
SECONDARY SOURCES
Non-asciidoc les that are used by backends.
Changes to them Gradle up-of-date status.
Relative to source root.
Some backends add default patterns.
asciidoctor {
secondarySources {
include '**/docinfo*.xml'
}
}
17 . 4

43.
RESOURCES
File that might be processed by backends, and will probably be
required in the nal output.
Changes to them affect Gradle up-to-date status.
asciidoctor {
resources {
from 'src/images', {
include '**/*.png'
}
}
}
17 . 5

44.
CONTROLLING RESOURCE COPY
asciidoctor {
copyAllResources()
copyNoResources()
copyResourcesOnlyIf 'html'
}
17 . 6

45.
INTERMEDIATE WORKING DIRECTORY
Some backends or extensions write working output into source
directory.
Keep source directory pristine.
asciidoctor {
useIntermediateWorkDir()
}
17 . 7

46.
INTERMEDIATE ARTIFACTS
Some extensions create artifacts that might need copying to nal
output
Implies useIntermediateWorkDir.
asciidoctor {
withIntermediateArtifacts {
include 'diag-*.png'
}
}
17 . 8

47.
PARALLEL PROCESSING
Documents can be converted in parallel.
asciidoctor {
parallelMode true
}
17 . 9

48.
ADDING ADDITIONAL DEPENDENCIES

49.
FINE-TUNING FORKS
Works with processMode of OUT_OF_PROCESS and JAVA_EXEC
Similar to JavaForkOptions used elsewhere in Gradle.
asciidoctor {
forkOptions {
minHeapSize = '512m'
}
}
