About SE4FP 2026

2nd Workshop on Software Engineering for Functional Programming

Although functional programming languages are not yet as popular as object-oriented ones, their growing relevance in the industry has become increasingly evident in recent years. However, the application of software engineering techniques to systems built with these languages remains underexplored in academia, leaving many open questions to be investigated.

In this context, the 2nd Workshop on Software Engineering for Functional Programming (SE4FP 2026) represents an excellent opportunity to bridge this gap. The event aims to create a space where members of academia and industry can share and discuss experiences, best practices, tools, and research related to applying software engineering principles to systems developed with functional programming languages. In addition to fostering relevant discussions, the workshop seeks to serve as a bridge for establishing collaborations between research groups and between academia and industry, opening up new opportunities for investigation.

In 2026, SE4FP is co-located with the 17th Brazilian Conference on Software: Theory and Practice (CBSoft 2026).

The main goal of this workshop is to promote broad and diverse discussions on the application of software engineering to functional programming. More specifically, it aims to:

• •    Attract more researchers interested in related topics, helping to build and strengthen the Brazilian community working in this area;
• •    Discuss the challenges of using functional programming languages in production systems;
• •    Assess the compatibility and applicability of studies conducted on object-oriented systems in the context of functional systems;
• •    Promote best engineering practices and tools specifically designed for systems implemented with functional programming languages.

Important Dates:

All dates refer to midnight 23:59:59 AoE

Reviewing Process:

The workshop proceedings will be published as part of the CBSoft 2026 proceedings and made available online in SBC's Digital Library (SOL). The number of papers accepted for the event will be determined based on the final program and the quantity and technical quality of the submissions received.

The review process will follow a double-blind methodology. Therefore, both authors and reviewers must take the necessary steps to preserve anonymity. Each submitted paper will be reviewed by at least three members of the program committee, composed of professors and researchers from various areas of Computer Science whose expertise aligns with the workshop topics. This committee will include professionals from both national and international institutions.

The selection of papers will be based on the following criteria:

• •    Originality and Timeliness
• •    Contribution and Technical Soundness
• •    Relevance to Software Engineering for Functional Programming
• •    Methodological Rigor
• •    Verifiability, Transparency, and Replicability
• •    Readability, Organization, and Presentation

Although not mandatory, we encourage authors to provide replication or artifact packages. This will also be considered a positive aspect by reviewers when recommending acceptance.

Submissions will be desk-rejected and not sent for review if they:

• •    Are out of scope of the workshop's call for papers;
• •    Have been previously published in another venue or journal;
• •    Do not follow the required formatting guidelines; or
• •    Do not comply with the anonymization rules of the double-blind review process.

Submission Guidelines:

Authors must submit original work that has not been published elsewhere nor is currently under review. Papers for the SE4FP 2026 may be written in Portuguese or English, with papers in English providing greater international visibility.

Submissions must be in Adobe Portable Document Format (PDF) and must strictly adhere to the template, which is also available for download. It is important to note that although this template is an adaptation of the ACM conference format, the original template (ACM_SigConf) must not be used. This same adapted template will be used across all symposia and workshops that are part of CBSoft 2026.

To ensure double-blind anonymization during the initial submission and review process, authors must include the anonymous option in the document preamble:

\documentclass[sigconf,anonymous]{acmart}

For all SE4FP 2026 Tracks, the following command containing the event information must also be used:

\acmConference[SE4FP 2026]{2nd Workshop on Software Engineering for Functional Programming}{September 8, 2026}{São Paulo, SP, Brazil}

All authors are advised to carefully review the checklist available at the end of the samples/cbsoft-acm-like.tex file to ensure that their papers comply with the template and the provided instructions.

In this edition, the workshop will accept two types of submissions:

• • Research papers (Max. 5 pages + 1 page for references) - we welcome submissions of research and experience papers that present original contributions, novel approaches, or preliminary results in the field of Software Engineering as applied to functional programming languages. Submissions should clearly present the problem being addressed, the proposed solution or findings, and their relevance to the software engineering and functional programming communities.
• 
  
• • Industry papers (Max. 3 pages + 1 page for references) - we invite developers to submit works focused on real-world experiences applying Software Engineering practices to code written in functional programming languages currently in production — including testing strategies, tools, architectures, methodologies, design decisions, development processes, specific challenges faced, and more. In other words, we are interested in experience reports that describe what developers of production-level code written in functional languages have been learning in practice. If you're unfamiliar with writing academic papers or their typical structure, we recommend reading papers accepted in the industry tracks of other conferences. This will help you get a feel for the format and find inspiration. For example, the papers accepted in the industry track of SE4FP 2025 are publicly available at the following link, making them an excellent starting point.

It is important to note that it is possible to submit papers with fewer pages than the limits of each track. All papers must be submitted electronically in PDF Format through JEMS.

IMPORTANT CLARIFICATION: Papers submitted to SE4FP may focus on software engineering applied to systems developed using either functional programming languages (e.g., Elixir, Erlang, Clojure, Haskell, etc.) or multi-paradigm languages (e.g., Python, JavaScript, Java, Rust, etc.), provided they place strong emphasis on functional programming features, such as list comprehensions, pattern matching, higher-order functions, pure functions, immutability, among others.

Authors must ensure their identities are not disclosed during the double-blind review process. This means that names and institutional affiliations should not appear on the title page or in the headers of the submission. Additionally, any self-citations should be written in the third person. If you plan to submit any supplementary artifacts, they should also be anonymized. Tools are available to assist with this, such as Anonymous GitHub, an open-source solution designed to help anonymize GitHub repositories efficiently. The SE4FP strongly encourages authors to make their artifacts publicly accessible. However, suppose authors prefer to avoid the risk of compromising anonymity during the review. In that case, they may include links to these artifacts in the camera-ready version, should the paper be accepted.

Ethics and Publication Conduct

All submitted papers must comply with the Code of Conduct for Authors in Publications of the Brazilian Computer Society (SBC).

On the use of AI (Artificial Intelligence) or AI-assisted technologies:

When submitting to SE4FP 2026, the authors acknowledge that they comply with the Generative AI usage policy, based on existing policies proposed by IEEE, ACM, and Springer.

• It is forbidden to:
• •    List Generative AI tools and technologies, such as ChatGPT, as authors of works;
• •    Use texts or sections entirely produced by generative AI tools

• It is allowed (with explicit disclosure in the acknowledgments) to:
• •    Use generative AI tools to create parts of the content, with disclosure in the paper acknowledgments indicating what was generated and which tool was used. It is important to check the terms of use of the tool, which is the responsibility of the authors. For example, in the acknowledgments, you can use: ChatGPT was used to generate the first paragraph of Section 3 and to generate Table 3.2.

• It is allowed (no need to mention):
