We encourage everyone interested in Lisp to participate. The European Lisp Symposium invites high quality papers about novel research results, insights and lessons learned from practical applications, and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. 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 Technical Program ~~~~~~~~~~~~~~~~~ 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 (cf. https://european-lisp-symposium.org/pepms.html). * 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 successful use of a Lisp dialect 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. For information on the submission format, please refer to the "Submission" section at https://www.european-lisp-symposium.org/2025.
