3rd Workshop on Type-Driven Development (TyDe 2018)

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. The workshop brings together leading researchers and practitioners who are using or exploring types as a means of program development.

Call for submissions

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

Invited speaker

K. Rustan M. Leino

Program Committee

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:

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 Extended abstracts will be distributed to workshop attendees but will not be published in the formal proceedings.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:


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


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

Travel Support

Student attendees with accepted papers can apply for a SIGPLAN PAC grant to help cover travel expenses. PAC also offers other support, such as for child-care expenses during the meeting or for travel costs for companions of SIGPLAN members with physical disabilities, as well as for travel from locations outside of North America and Europe. For details on the PAC program, see its web page:
