Call For Papers

Scala is a general purpose programming language designed to express common
programming patterns in a concise, elegant, and type-safe way. It smoothly
integrates features of object-oriented and functional languages.

The Scala Symposium is the leading forum for researchers and practitioners
related to the Scala programming language. We welcome a broad spectrum of
research topics and support many submission formats for industry and
academia alike.

This year’s Scala Symposium is co-located with ECOOP 2019 in London, UK.

# Topics of Interest #

We seek submissions on all topics related to Scala, including (but not
limited to):

* Language design and implementation – language extensions, optimization,
and performance evaluation.
* Library design and implementation patterns for extending Scala –
stand-alone Scala libraries, embedded domain-specific languages, combining
language features, generic and meta-programming.
* Formal techniques for Scala-like programs – formalizations of the
language, type system, and semantics, formalizing proposed language
extensions and variants, dependent object types, type and effect systems.
* Concurrent and distributed programming – libraries, frameworks, language
extensions, programming models, performance evaluation, experimental
* Big data and machine learning libraries and applications using the Scala
programming language.
* Safety and reliability – pluggable type systems, contracts, static
analysis and verification, runtime monitoring.
* Interoperability with other languages and runtimes, such as JavaScript,
Java 8 (lambdas), Graal and others.
* Tools – development environments, debuggers, refactoring tools, testing
* Case studies, experience reports, and pearls.

Do not hesitate to contact the Program Chair (nate.nystrom at if you
are unsure whether a particular topic falls within the scope of Scala 2019.

# Important dates #

* Paper submission: April 9, 2019
* Paper notification: May 24, 2019
* Student talk submission: May 31, 2019
* Student talk notification: June 14, 2019
* Camera ready: June 7, 2019
* Scala Symposium 2019: July 17, 2019

All deadlines are at the end of the day, “Anywhere on Earth” (AoE).

# Submission Format #

To accommodate the needs of researchers and practitioners, as well as
beginners and experts alike, we seek several kinds of submissions.

* Full papers (at most 10 pages, excluding bibliography)
* Short papers (at most 4 pages, excluding bibliography)
* Tool papers (at most 4 pages, excluding bibliography)
* Student talks (short abstract only, in plain text)
* Open-source talks (short abstract only, in plain text)

Accepted papers (either full papers, short ones or tool papers, but not
student talks) will be published in the ACM Digital Library. Detailed
information for each kind of submission is given below. Submissions should
be in acmart/sigplan style, 10pt font. Formatting requirements are detailed
on the SIGPLAN Author Information page (

Scala 2019 submissions must conform to the ACM Policy on Prior Publication
and Simultaneous Submissions and to the SIGPLAN Republication Policy.

Please note that at least one author of each accepted contribution must
attend the symposium and present the work. In the case of tool
demonstration papers, a live demonstration of the described tool is

# Full and Short Papers #

Full and short papers should describe novel ideas, experimental results, or
projects related to the Scala language. In order to encourage lively
discussion, submitted papers may describe work in progress. Additionally,
short papers may present problems and raise research questions interesting
for the Scala language community. All papers will be judged on a
combination of correctness, significance, novelty, clarity, and interest to
the community.

In general, papers should explain their original contributions, identifying
what has been accomplished, explaining why it is significant, and relating
it to previous work (also for other languages where appropriate).

# Tool Papers #

Tool papers need not necessarily report original research results; they may
describe a tool of interest, report practical experience that will be
useful to others, new Scala idioms, or programming pearls. In all cases,
such a paper must make a contribution which is of interest to the Scala
community, or from which other members of the Scala community can benefit.

Where appropriate, authors are encouraged to include a link to the tool’s
website. For inspiration, you might consider advice in,
which we however treat as non-binding. In case of doubts, please contact
the program chair.

# Student Talks #

In addition to regular papers and tool demos, we also solicit short student
talks by bachelor/master/PhD students. A student talk is not accompanied by
paper (it is sufficient to submit a short abstract of the talk in plain
text). Student talks are about 5-10 minutes long, presenting ongoing or
completed research related to Scala. In previous years, each student with
an accepted student talk received a grant (donated by our sponsors)
covering registration and/or travel costs.

# Open-Source Talks #

We will also accept a limited number of short talks about open-source
projects using Scala presented by contributors. An open-source talk is not
accompanied by a paper (it is sufficient to submit a short abstract of the
talk in plain text). Open-source talks are about 10 minutes long and should
be about topics relevant to the symposium. They may, for instance, present
or announce an open-source project that would be of interest to the Scala
