API Blueprint (Lifetime) — IntelliJ Platform plugin

This plugin adds support for the API Blueprint format (.apib) inside IntelliJ-based IDEs.

Main features

• .apib file type support

  • Recognizes files with the apib extension and treats them as Markdown-based API Blueprint documents.

• API Blueprint semantic syntax highlighting

  • Highlights common API Blueprint structures (sections, keywords, HTTP methods, parameters, etc.) on top of the Markdown language.

• Customizable colors

  • Exposes API Blueprint-specific highlighting keys in the IDE color settings so you can adapt the theme to your preference.

• Startup checks & notifications

  • Runs a lightweight startup activity and uses IDE notifications for important messages.
  • Includes license validation for the “Lifetime” distribution.

Getting started

1. Install the plugin from Settings/Preferences → Plugins.
2. Open an existing .apib file (or create a new one).

You can use the sample files in this repository:

• example-api.apib
• test-comprehensive.apib

Configure highlighting

Go to Settings/Preferences → Editor → Color Scheme and look for the API Blueprint-related entries (provided by this plugin) to adjust colors and styles.

Compatibility

The plugin targets IntelliJ Platform IDEs and depends on the bundled Markdown support (org.intellij.plugins.markdown).
