IntelliJ AsciiDoc Plugin

A plugin for the IntelliJ platform (IntelliJ IDEA, RubyMine, etc) that provides support for the AsciiDoc markup language. You can install the plugin (named "AsciiDoc") from the plugins section inside your Jetbrains IDE or download it from the Jetbrains Plugin Repository.

If you want to use the JavaFX instead of the Swing preview, you’ll need to run IntelliJ with 64bit Java. From 2017.1 onwards 64bit Java is included even in the Windows versions. See for more information.

If your IntelliJ distribution doesn’t come with 64bit Java, you’ll need to have an environment variable IDEA_JDK or IDEA_JDK64 pointing to the installation folder of a 64bit Java. See Jetbrains support database for more information.

This project uses AsciiDoctorJ and JRuby for the rendering of the AsciiDoc content.

For the conversion of Markdown to AsciiDoc, we use Pegdown and the Markdown to AsciiDoc converter.


This plugin is built using Gradle. If you build or run it the first time it will download the community edition of IntelliJ automatically.

If you have developed the plugin before it changed to Gradle you might want to remove the contents of your .idea folder to trigger a re-import of the Gradle project.

To build this plugin, you need to run:

./gradlew -Dfile.encoding=UTF-8 buildPlugin

The ZIP file with plugin to distribute will be located in build/distributions.

To run the plugin for development you’ll need to start

./gradlew -Dfile.encoding=UTF-8 runIdea

This plugin is based on the Intellij Markdown plugin by Julien Nicoulaud.

Also, great help was received from Harro Lissenberg, Alexander Schwartz and Dan Allen. Thank you all for your support!
