=========================================================================
                The Eleventh International Workshop on
                      TYPE-DRIVEN DEVELOPMENT
               Call for papers and extended abstracts

                    Paris, 26-27th August 2026
                   https://tydeworkshop.org/2026
=========================================================================

The Workshop on Type-Driven Development (TyDe) aims to show how static
type information may be used effectively in the development of
computer programs. Organised as part of FPW26 (Functional Programming
Workshops 2026), 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.

### Important dates (all are AoE) ###
* June 3rd  2026 - Research Papers Submission Deadline
* June 24th 2026 - Extended Abstracts Submission Deadline
* July 10th 2026 - Notification
* July 17th 2026 - Camera-Ready Paper Submission Deadline
* August 26-27th 2026 - Workshop at FPW26

### Proceedings and Copyright ###

TO BE CONFIRMED

We will aim to have formal proceedings for full-length papers,
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 (3 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://tyde2026.hotcrp.com

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

> https://www.sigplan.org/Resources/Author/

Note that submissions should use the new acmart format and the
two-column sigplan subformat (not to be confused with the one-column
acmsmall subformat).

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

### Presentations ###

We expect that each accepted submission is presented at the
workshop. Presentations are around 20 minutes plus questions. Remote
presentation is possible.

### Workshop Organization ###

Organizing Committee:
- Guillaume Allais (co-chair) University of Strathclyde, UK
- Tom Schrijvers (co-chair) KU Leuven, BE
