Latest version:

By default:

AsciiDoc files should be stored under src/docs/.
Images should be stored under src/images, which can then be referenced via AsciiDoc image macros.
Any files ending with .j2 will first be processed by Jinjava (Java port of Python Jinja2).
A number of Jinja2 macros are added by default. See brightSPARK Labs Jinja2 Macros.

Running ./gradlew build will generate PDF and HTML of the documentation.

If docker buildx is present on the system, then in addition to the AsciiDoc HTML backend output, it will also generate a Jekyll based static website.

3.1. Tasks

The tasks added by this plugin appear under the BrightSPARK Labs - Docs tasks group. E.g.

$ ./gradlew task | sed -n '/BrightSPARK/,/^$/p'

BrightSPARK Labs - Docs tasks
-----------------------------
bslAsciidoctor - Alias for `asciidoctor` task.
bslAsciidoctorPdf - Alias for `asciidoctorPdf` task.
bslAsciidoctorPdfInDocker - Runs the Asciidoctor PDF tasks within a Docker container. Useful as
  the CLI diagramming CLI tools do not need to be installed on the local machine.
bslAsciidoctorPdfVersioned - Creates PDF files with version string in filename.
cleanJekyllWebsite - Cleans the Jekyll website out of the build directory.
cleanJinjaPreProcess - Cleans the Jinja2 processed documents out of the build directory.
generateDockerfile - Generates a Dockerfile for hosting the documentation as a static website.
generateJekyllWebsite - Generates a Jekyll based website from the documents using docker.
jinjaPreProcess - Performs Jinja2 pre-processing on documents.

Note	`generateJekyllWebsite` is only available if `docker buildx` is present on the system.

4. Jinja2 Context Map

Each template file is passed to the Jinja2 engine to be rendered into the final file.The template can reference variables defined in a context map (Map<String, Object>). This context map is generated by the system and is dynamic, containing different values based on the template file currently being rendered. The shape of this context map is detailed in this section.

Template files can reference any of the variables in this map via standard Jinja2 syntax. E.g.

{{ sys.project_version }}

{{ output_file.last_commit.timestamp | datetimeformat("%Y-%m-%d at %H:%M %Z", "Australia/Sydney") }}

{{ output_file.last_commit.timestamp_formatted.iso_utc_space }}

4.7. Plugin configuration variables

The docsPluginConfig object as defined in the Configuration section below.

config:
  ...

4.8. Buildscript variables

The gradle buildscript can be used to dynamically create files which are added to the Jinja2 context. These generated files need to be placed in the following directory prior to calling the jinjaPreProcess task:

build/brightsparklabs/docs/buildscriptVariables/

The files need to be named analogous to what they are named in the source templates directory, and they will be added to Jinja2 context is the corresponding location under a buildscript_vars key.

The following helpers are exposed under project.ext.bslGradleDocs:

File buildscriptVariablesDir: Returns the buildscript variables directory.
File createBuildscriptVariablesFile(String path): Creates a file at the specified path under the buildscript directory.

E.g.

Given:

Templates stored in the default location (src/docs).
A global variables file at the default location (src/variables.yaml).

Code in the build.gradle buildscript which has populated:

build/brightsparklabs/docs/buildscriptVariables/

E.g. Via a task:

// build.gradle

import org.yaml.snakeyaml.Yaml

tasks.register('generateVariables') {
    outputs.upToDateWhen { false }

    doLast {
      // ---------------------------------------------------------
      // Example 1: Reshape source variables.
      // ---------------------------------------------------------

      def adminGuideFilePath = 'src/docs/devops/administrator-guide.adoc.j2.yaml'
      def adminGuideFile = project.file(adminGuideFilePath)

      def yamlParser = new Yaml()
      def adminGuideVars = yamlParser.load(adminGuideFile.text)

      // Add an ID to each step.
      adminGuideFile.steps.eachWithIndex { item, index ->
        item.id = "${index + 1}.padLeft(5, '0')
      }

      def buildscriptVarsFile = project.ext.bslGradleDocs.createBuildscriptVariablesFile(adminGuideFilePath)
      buildscriptVarsFile.text = yamlParser.dump(adminGuideVars)

      // ---------------------------------------------------------
      // Example 2: Create global buildscript variables.
      // ---------------------------------------------------------

      def buildscriptGlobalVarsFile =
        project.ext.bslGradleDocs.createBuildscriptVariablesFile('variables.yaml')
      buildscriptGlobalVarsFile.text = """
        ---
        foo: 12
        bar: 2
        """.stripIndent().stripLeading()
    }
}
project.tasks.named('jinjaPreProcess'){ dependsOn 'generateVariables' }

   // Gem-based Jekyll theme to use when styling the website.
   // See https://jekyllrb.com/docs/themes/#understanding-gem-based-themes.
   // Default: `just-the-docs`.
   website.theme = 'minimal-mistakes-jekyll'
}

6.1. brightSPARK Labs Jinja2 Macros

If the configuration field autoImportMacros is set to true (default) then the following macros shall be be available under the brightsparklabs namespace:

add_default_attributes() - Adds the standard set of AsciiDoc attributes to the document.

These can be used as follows:

{{ brightsparklabs.add_default_attributes() }}

Macros are defined in:

src/main/resources/brightsparklabs-macros.j2

6.2. Asciidoctorj Diagram

asciidoctorj-diagram can be enabled as per standard practice in build.gradle:

// Support asciidoctor-diagram image generation.
asciidoctorj {
    modules {
        diagram.use()
    }
}

In order to make use of the various diagramming formats, the backing tool needs to be installed on the system.

The CLI tools listed below are installed in the containers used by the asciidoctorPdfDocker and generateJekyllWebsite tasks. I.e. These tasks can be used to create documents containing diagrams of the listed types without needing to install those tools on the local workstation.

graphviz dot

Allowing the use of graphviz/plantuml diagrams.

  Generate PNG file (with random name) from graphviz spec.

  [graphviz]
  ....
  digraph G {
      main -> parse -> execute;
      main -> init;
      main -> cleanup;
      execute -> make_string;
      execute -> printf
      init -> make_string;
      main -> printf;
      execute -> compare;
  }
  ....

  Generate `my-diagram.svg` from plantuml spec.

  [plantuml,my-diagram,svg]
  ....
  @startjson
  {
     "fruit":"Apple",
     "size":"Large",
     "color": ["Red", "Green"]
  }
  @endjson
  ....

vega-cli

Allowing the use of Vega/Vega-Lite diagrams.

  [vega,bar-chart,svg]
  ....
  {
    "description": "A simple bar chart with embedded data.",
    "data": {
      "values": [
        {"a": "A","b": 28}, {"a": "B","b": 55}, {"a": "C","b": 43},
        {"a": "D","b": 91}, {"a": "E","b": 81}, {"a": "F","b": 53},
        {"a": "G","b": 19}, {"a": "H","b": 87}, {"a": "I","b": 52}
      ]
    },
    "mark": "bar",
    "encoding": {
      "x": {"field": "a", "type": "ordinal"},
      "y": {"field": "b", "type": "quantitative"}
    }
  }
  ....

7. Jekyll Website

By default the generated Jekyll website uses the Just the Docs theme.

By default all pages will appear as top level pages in the main navigation. If you want to setup nested navigation, you will need to set that up explicitly as detailed in the Navigation Structure documentation.

A basic example is:

$ tree

src
└── docs
    ├── data-model
    │   ├── component-x-data-model.adoc.j2
    │   ├── component-x-data-model.adoc.j2.yaml
    │   └── index.adoc.j2
    └── index.adoc.j2

$ cat src/docs/index.adoc.j2
 Data Model
brightSPARK Labs <[email protected]>
{{ brightsparklabs.add_default_attributes() }}
:page-has_children: true

$ head src/docs/component-x-data-model.adoc.j2
 Component X Data Model
brightSPARK Labs <[email protected]>
{{ brightsparklabs.add_default_attributes() }}
:page-parent: Data Model

The attributes to note:

:page-has_children: true on the parent page to indicate supports nested pages.
:page-parent: Data Model on the child page to nest it under the parent page.

NOTE: Just the Docs only supports a maximum of 3 levels of nesting.

7.1. Website Dockerfile

A Dockerfile for building the website can be generated via the generateDockerfile task. This can be leveraged to work with the gradle-docker plugin by doing the following:

Make the gradle-docker plugin’s buildDockerImages task depend on this plugin’s generateDockerfile task.
Add the path of the generated Dockerfile to the gradle-docker plugin’s configuration block in the dockerFileDefinitions list.

8. Testing during development

To test plugin changes during development:

# bash

# create a test application
mkdir gradle-docs-test
cd gradle-docs-test
gradle init --type java-application --dsl groovy
# add the plugin (NOTE: do not specify a version)
sed -i "/plugins/ a id 'com.brightsparklabs.gradle.docs'" build.gradle

# setup git (plugin requires repo to be under git control)
git init
git add .
git commit "Initial commit"
git tag -a -m "Tag v0.0.0" 0.0.0

# run using the development version of the plugin
gradlew --include-build /path/to/gradle-docs <task>
