 CALL FOR PAPERS

 5th Workshop on Type-Driven Development (TyDe 2020)
 Co-Located with ICFP 2020 (Online)

 https://icfp20.sigplan.org/home/tyde-2020
--------------------------------------------------------------------------------

# Goals of the workshop

The workshop on Type-Driven Development aims to show how static type
information may be used effectively in the development of computer
programs. Co-located with ICFP, this workshop brings together leading
researchers and practitioners who are using or exploring types as a
means of program development.

We welcome all contributions, both theoretical and practical, on a
range of topics including:

-   dependently typed programming;
-   generic programming;
-   design and implementation of programming languages, exploiting types
    in novel ways;
-   exploiting typed data, data dependent data, or type providers;
-   static and dynamic analyses of typed programs;
-   tools, IDEs, or testing tools exploiting type information;
-   pearls, being elegant, instructive examples of types used in the
    derivation, calculation, or construction of programs.

# Coronavirus Update (2020-5-2)

Due to the coronavirus pandemic, TyDe will be held online alongside ICFP.
We will strive to accommodate authors from all time zones, e.g. by allowing
pre-recorded videos or by spreading out the talks throughout the day,
following the lead of the main conference. Updates will be posted on the
website and sent to all authors of submitted papers as they become
available.

# Proceedings and Copyright

We will have formal proceedings, published by the ACM. Accepted
papers will be included in the ACM Digital Library. Authors must grant
ACM publication rights upon acceptance, but may retain copyright if they
wish. Authors are encouraged to publish auxiliary material with their
paper (source code, test data, and so forth). The proceedings will be
freely available for download from the ACM Digital Library from one week
before the start of the conference until two weeks after the conference.

The official publication date is the date the papers are made
available in the ACM Digital Library. This date may be up to two weeks
prior to the first day of the conference. The official publication
date affects the deadline for any patent filings related to published
work.

# Submission details

Submissions should fall into one of two categories:

-   regular research papers (12 pages)
-   extended abstracts (2 pages)

The bibliography will not be counted against the page limits for
either category.

Regular research papers are expected to present novel and interesting
research results, and will be included in the formal
proceedings. Extended abstracts should report work in progress that
the authors would like to present at the workshop. Extended abstracts
will be distributed to workshop attendees but will not be published in
the formal proceedings.

We welcome submissions from PC members (with the exception of the two
co-chairs), but these submissions will be held to a higher standard.

Submission is handled through HotCRP:

  https://tyde20.hotcrp.com

All submissions should be in portable document format (PDF) and
formatted using the ACM SIGPLAN style guidelines:

  http://www.sigplan.org/Resources/Author/

*Note* that the ACM SIGPLAN style guidelines have changed from
previous years! In particular, submissions should use the new
‘acmart’ format and the two-column ‘sigplan’ subformat (not to be
confused with the one-column ‘acmlarge’ subformat).

Extended abstracts must be submitted with the label 'Extended
abstract' clearly in the title.

# Important Dates

-   May 19: Paper submission deadline
-   May 26: Extended abstract submission deadline
-   June 9: Author notification
-   June 30: Camera ready deadline
-   Aug 23: Workshop

# Participant Support

Student attendees with accepted papers can apply for a SIGPLAN PAC grant to
help cover participation-related expenses. PAC also offers other support,
such as for child-care expenses during the meeting or for accommodations
for members with physical disabilities. For details on the PAC program, see
its web page:

  http://www.sigplan.org/PAC/

(Please contact PAC organizers as early as possible if you will need
accommodations, as protocols may have shifted due to the coronavirus
situation.)
