Not sure where to ask your question?
Use the guidelines below to choose the right support channel. This helps you get answers faster and keeps discussions focused and searchable.
Communication Channels
Github
Use GitHub for concrete, technical topics.
Best for:
- Reporting bugs and regressions
- Requesting or discussing new features
- Component-specific technical questions
- Proposing improvements
Issues and discussions are tracked per component and are the preferred place for technical follow-up and long-term reference.
Project Mailing List
The mailing list is suited for broader or cross-cutting topics.
Best for:
- Design discussions spanning multiple components
- Project-wide questions or announcements
- Topics that benefit from longer-form discussion
Chat
For informal and quick interaction, please use our Matrix chat channels.
Best for:
- Quick questions
- Clarifying small issues
- Getting in touch with other users and contributors
Please note that chat is community-driven and responses may vary in time. For issues that require follow-up or tracking, GitHub is preferred.
Where should I ask my question?
A simple rule of thumb:
- Is it a question or discussion others might benefit from later?
→ Use GitHub Discussions. - Is it a bug or concrete problem that needs tracking?
→ Use GitHub Issues. - You want to discuss an idea or design across components?
→ Use the mailing list. - You just need quick feedback or clarification?
→ Try the chat.
If in doubt, GitHub is usually the safest choice.

Before you ask
A few small steps help others help you more effectively:
- Search existing issues and discussions first
- Mention the Eclipse 4diac version you are using
- Include relevant logs, screenshots, or error messages
- If possible, provide a minimal example to reproduce the problem
- Clearly state what you expected to happen and what happened instead
Well-prepared questions tend to receive faster and more precise answers.
