The series of CoqPL workshops provide an opportunity for programming languages researchers to meet and interact with one another and members from the core Coq development team. At the meeting, we will discuss upcoming new features, see talks and demonstrations of exciting current projects, solicit feedback for potential future changes, and generally work to strengthen the vibrant community around our favorite proof assistant.

Topics in Scope

  • General purpose libraries and tactic language extensions
  • Domain-specific libraries for programming language formalization and verification
  • IDEs, profilers, tracers, debuggers, and testing tools
  • Reports on ongoing proof efforts conducted via (or in the context of) the Coq proof assistant
  • Experience reports from Coq usage in educational or industrial contexts

Workshop Format

The workshop format will be driven by you, members of the community. We will solicit abstracts for talks and proposals for demonstrations and flesh out format details based on responses. We expect the final program to include experiment reports, panel discussions, and invited talks (details TBA). Talks will be selected according to relevance to the workshop, based on the submission of an extended abstract.

To foster open discussion of cutting edge research which can later be published in full conference proceedings, we will not publish papers from the workshop. However, presentations will be recorded and the videos made publicly available.
