Popular ways to connect with the Scala community include mailing lists, chat rooms, user groups, and conferences.
The community is also the source of many libraries, tools, and other resources around Scala.
The Scala mailing lists are covered by the Scala Code of Conduct.
This is our most beginner-friendly list:
- Scala-User: the main forum for questions and discussions, including beginner questions, about programming in Scala. Any question can and should receive a courteous and insightful answer.
This list is low-traffic and all posts are moderated:
- Scala-Announce: announcements of new Scala releases, tools, libraries, and other resources.
Other, more specialized lists:
- Scala-Language: discussions about the Scala language itself. Why Scala is the way it is, and how it could be different.
- Scala-Debate: the “any topic goes” list. While professional courtesy and respect must be maintained, discussion and speculation on controversial topics and “what-if” type questions can occur. Threads sometimes migrate here from other lists if they become too specialized, lengthy, or contentious.
- Scala-Tools: specifically for tooling around Scala, such as editors and build tools.
- Scala-SIPs: interest group devoted to Scala Improvement Process (SIP) and Scala Library Improvement Process (SLIP) proposals. If you want to see what’s coming down the pipe and you’d like to be involved, this is the mailing list for you.
And most specialized of all:
- Scala-Internals: for discussing development work on the Scala compiler and standard library. Core maintainers and active open-source contributors are both welcome. (If you’re not sure if your thread belongs here, ask a contributor, or try another list first.)
No Job Postings
Job listings are not allowed on the mailing lists. While we’re all very glad to see more and more Scala jobs, please confine these listings to more appropriate forums.
The main Gitter room for Scala is:
- scala/scala: like the scala-user mailing list. Questions, general discussion, etc.
Other, more specialized rooms include:
- spark-scala/Lobby: for discussions and questions about using Scala for Spark programming
There are many other rooms devoted to individual Scala libraries and technologies.
Rooms about the future of Scala:
- scala/contributors: like the scala-internals mailing list. For Scala contributors to discuss language internals.
- scala/slip: for discussion of SLIPs and SIPs (Scala Library and Scala Improvement Process) proposals
IRC users can chat about Scala anytime on the Scala IRC channel:
See our events page.
Scala is an active topic on Stack Overflow, a very popular programmer Q&A site.
There is a large and active Scala community on the /r/Scala subreddit.
Sources of Scala News
Many Scala users are active on Twitter for sharing Scala-related news items and opinions. Ask your Scala friends who they follow on Twitter (besides @Scala_lang!).
