*NEW FORMAT* This year, we solicit *talk proposals* instead of research papers.

Important Dates
---------------
* Submission deadline: July 10, 2025
* Author notification: August 4th, 2025
* Camera Ready Submission: August 25th, 2025
* Workshop: October 13th, 2025

The Scala Workshop is the continuation of the Scala Symposium, providing a forum for researchers and practitioners to discuss the design, implementation, and applications of the Scala programming language. Topics include language features, compiler internals, type systems, libraries, tools, and industrial applications.

This year, the workshop follows a simplified format, focusing on talk proposals rather than full papers. The goal is to facilitate discussion and exchange of ideas without the overhead of formal publications. Talks can cover ongoing research, practical experience, or perspectives on Scala and its ecosystem.

# Call for Presentations

The Scala Workshop 2025 invites talk proposals on all aspects of the Scala programming language, including but not limited to:
* Language design and implementation
* Type systems and functional/object-oriented programming paradigms
* Compiler development and optimizations
* Libraries, frameworks, and tooling
* Applications of Scala in industry and research
* Experience reports and case studies
* Performance, scalability, and concurrency
* Interoperability with other languages and ecosystems

Talks are expected to be around 20 minutes long, plus 5 minutes for discussions.

## Submission Format

We encourage submissions in the form of a talk description (about two pages excluding bibliography), outlining the topic, key ideas, and relevance to the Scala community. Submissions should not be anonymous and should be in PDF format. We recommend LaTeX-produced PDFs with the current ACM Template (https://urldefense.com/v3/__https://www.acm.org/publications/authors/submissions__;!!IBzWLUs!Uty3Jz6z3KERLIH9Rn7kG9vyEzxGiuS1UGh9PI2OaV1qqLNcMguxT5e39d662GeA3TMs0eaC45Cmb8x1kSg2a-Kay2OCoalMtyIuOzqJQg$ ) using the option \documentclass[sigplan,nonacm]{acmart}. Talk proposals will be published in form of post-proceedings on the workshop website, where presenters may optionally include their talk slides as well. The page limit is not strictly enforced, but we encourage authors to keep submissions concise and to the point. Please avoid going overboard.

## Evaluation Criteria

Submissions will be evaluated based on the following criteria (not all criteria need to be satisfied):
* Relevance: Alignment with topics of interest to the Scala community.
* Clarity: Effectiveness of communication and structure of the submission.
* Originality: Novelty of ideas, techniques, or applications presented.
* Discussion Potential: Likelihood of inspiring engaging and productive conversations.
* Rigor: Technical accuracy, depth, and soundness of arguments.

## How to Submit

Submissions will be accepted through the workshop’s hotcrp instance (https://urldefense.com/v3/__https://scala-workshop.epfl.ch/__;!!IBzWLUs!Uty3Jz6z3KERLIH9Rn7kG9vyEzxGiuS1UGh9PI2OaV1qqLNcMguxT5e39d662GeA3TMs0eaC45Cmb8x1kSg2a-Kay2OCoalMtyKqcCo_yQ$ ). For any questions, feel free to contact the organizers at scala-workshop at epfl.ch.

## Attendance

We will support hybrid participation to make the workshop accessible to a wider audience. While we encourage in-person attendance for the best experience, remote participation will be fully supported to ensure everyone can contribute and engage.
