European Lisp Symposium

- 2026, Kraków
(and online)

Submissions

Submission topics include, but are not limited to:

  • Context-, aspect-, domain-oriented and generative programming
  • Macro-, reflective-, meta- and/or rule-based development approaches
  • Language design and implementation
  • Language integration, inter-operation and deployment
  • Development methodologies, support and environments
  • Educational approaches and perspectives
  • Experience reports and case studies

We invite submissions in the following forms. Papers and experience reports must not overlap significantly with the authors’ previously published work in a peer reviewed publication, and must not be under review on another journal or conference. Also, authors must agree with our publication ethics and malpractice statement.

  • Papers: Technical papers of up to 8 pages that describe original results or explain known ideas in new and elegant ways.
  • Experience reports: papers of up to 6 pages describing a Lisp success story and/or analyzing obstacles that have kept it from working in practice.
  • Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest.
  • Demonstrations: Abstracts of up to 4 pages for demonstrations of tools, libraries, and applications.

Submissions should be uploaded to EasyChair. VERY IMPORTANT: to help us with the review process please indicate the type of submission in the title field in the submission form.

LaTeX submissions are strongly encouraged. Please use the LaTeX article template available here to format your submission.

In general, all submissions should be formatted following the ACM SIGS guidelines and include ACM Computing Classification System 2012 concepts and terms. Appropriate TeX and Word templates can also be found on the ACM publications page.

Please use the ACM Computing Classification System site to generate the CCS codes. In order to add a concept, navigate to it using the boxes, and select "Assign This CCS Concept" on the left side. You should select one high relevance concept, and up to four medium or low relevance concepts. Once you are done, simply copy the CCS display into the Word document. If you are using TeX, select "View CCS TeX Code" and copy the displayed code into your TeX file. The templates should already include sections with bogus CCS codes, which you can simply replace with your own.

Invited Speakers

  • McCLIM and ECL -- Daniel Kochmański
  • Lambda: the Ultimate Paradigm -- François-René Rideau

    From its discovery in 1958, Lisp has been at the forefront of innovation in topics as diverse as Artificial Intelligence, Memory Management, Object-Oriented Programming, Control Structures, Human Computer Interaction—and much more.

    Then, in the 1990s, progress largely stopped in Lisp, to happen in other ecosystems. Some Lisp technology was abandoned and forgotten; and while there remains a niche community of Lisp hackers who keep producing wonderful innovation, it is largely not at the forefront of technological progress anymore.

    What happened? What made and makes Lisp such a good platform for creation? What advantages does Lisp still have? How can they be further amplified? What advantages did it lose? How can the effect be reduced or reversed? And what does the recent advent of Artificial Intelligence that can write software mean for the future of Lisp?

    Back in the day, Lispers used the slogan “Lambda the Ultimate ” to boast about how Lisp could get to the very essence of so many issues that others barely understood.

    While some Functional Programmers have tried to claim the “Lambda” slogan for themselves, I’ll argue why indeed Lisp has the “Lambda Nature” in ways that no other programming language does—precisely because Lisp is more than a programming language.

Tourism

Sunday May 10: excursion to the Wieliczka Salt Mine

The Wieliczka Salt Mine is a historic underground site near Kraków and a UNESCO World Heritage Site. The visit includes a guided walk through chambers carved in salt, underground lakes, and historical mining structures dating back several centuries. Join us for an exploration a this unique cultural and historical landmark.

WARNING: group excursions to the mine require a minimum of 25, and up to 40 participants. We thus need to reach at least 25 people in order to secure at least one group. We thus urge you to register as soon as possible, and no later than April 19th if you are interested, in order to help us secure the tour. Registrants will be refunded if the excursion cannot be organized.
