1. Introduction

We use asciidoc for writing documentation.

We chose asciidoc over Markdown because asciidoc, although a bit more complex than Markdown, provides more flexibility in formatting.

2. Editing Documentation

See UsingGradle.adoc to learn how to render .adoc files locally to preview the end result of your edits. Alternatively, you can download the AsciiDoc plugin for IntelliJ, which allows you to preview the changes you have made to your .adoc files in real-time.

3. Editing Diagrams

See UsingPlantUml.adoc to find out how to create and update the UML diagrams in the developer guide.

4. Publishing Documentation

See UsingTravis.adoc to learn how to deploy GitHub Pages using Travis.

5. Converting Documentation to PDF format

We use Google Chrome for converting documentation to PDF format, as Chrome’s PDF engine preserves hyperlinks used in webpages.

Here are the steps to convert the project documentation files to PDF format.

  1. Follow the instructions in UsingGradle.adoc to convert the AsciiDoc files in the docs/ directory to HTML format.

  2. Go to your generated HTML files in the build/docs folder, right click on them and select Open with → Google Chrome.

  3. Within Chrome, click on the Print option in Chrome’s menu.

  4. Set the destination to Save as PDF, then click Save to save a copy of the file in PDF format. For best results, use the settings indicated in the screenshot below.

6. Site-wide Documentation Settings

The build.gradle file specifies some project-specific asciidoc attributes which affects how all documentation files within this project are rendered.

Attributes left unset in the build.gradle file will use their default value, if any.
Table 1. List of site-wide attributes
Attribute question Description Default value

site-name

The name of the website. If set, the name will be displayed near the top of the page.

not set

site-githuburl

URL to the site’s repository on GitHub. Setting this will add a "View on GitHub" link in the navigation bar.

not set

site-seedu

Define this attribute if the project is an official SE-EDU project. This will render the SE-EDU navigation bar at the top of the page, and add some SE-EDU-specific navigation items.

not set

7. Per-file Documentation Settings

Each .adoc file may also specify some file-specific asciidoc attributes which affects how the file is rendered.

Asciidoctor’s built-in attributes may be specified and used as well.

Attributes left unset in .adoc files will use their default value, if any.
Table 2. List of per-file attributes, excluding Asciidoctor’s built-in attributes
Attribute name Description Default value

site-section

Site section that the document belongs to. This will cause the associated item in the navigation bar to be highlighted. One of: UserGuide, DeveloperGuide, LearningOutcomes*, AboutUs, ContactUs

* Official SE-EDU projects only

not set

no-site-header

Set this attribute to remove the site navigation bar.

not set

8. Site Template

The files in docs/stylesheets are the CSS stylesheets of the site. You can modify them to change some properties of the site’s design.

The files in docs/templates controls the rendering of .adoc files into HTML5. These template files are written in a mixture of Ruby and Slim.

Modifying the template files in docs/templates requires some knowledge and experience with Ruby and Asciidoctor’s API. You should only modify them if you need greater control over the site’s layout than what stylesheets can provide. The SE-EDU team does not provide support for modified template files.
