description	Writing and formatting guidance for ECOOP (European Conference on Object-Oriented Programming). Use when drafting, formatting, or submitting to ECOOP. Covers ACM acmart with sigplan format, anonymous double-blind review mode, ECOOP page limits (12 pages), formal semantics, theorem environments, code listings, camera-ready preparation with DOI/ISBN, and ACM-Reference-Format citations.

Page Limits

Section	Limit
Main paper (submission)	12 pages
References	No limit
Appendix	Permitted (not counted)

ECOOP enforces a strict 12-page limit for the main body. References and appendix do not count toward this limit, but reviewers are not required to read the appendix.

Anonymity Requirements

Double-blind review with anonymous class option:

1. Do not include author names anywhere in the submission
2. Use third person for self-citations: "Smith et al. showed..." not "we showed..."
3. Anonymize URLs (e.g., GitHub repositories)
4. Remove PDF metadata that reveals authorship
5. Do not include acknowledgments

Camera-Ready Differences

When preparing camera-ready after acceptance:

1. Remove review and anonymous options from \documentclass
2. Add \setcopyright{acmlicensed} or appropriate rights mode
3. Fill in \acmConference with full conference title and dates
4. Add \acmISBN, \acmDOI, and \acmPrice fields
5. Restore all author names and affiliations
6. Add acknowledgments if desired

Section Organization

Standard ECOOP paper structure:

1. Introduction — Problem, motivation, contributions (enumerate contributions explicitly)
2. Background — Technical context, OO programming foundations
3. Language/Approach — Core definitions, type system, semantics
4. Technical Development — Proofs, metatheory, design decisions
5. Implementation — Compiler/interpreter details
6. Evaluation — Experimental results
7. Related Work — Positioning against prior art
8. Conclusion — Summary and future work
9. References

Theorem Environments

ECOOP papers commonly use formal reasoning environments:

\theoremstyle{plain}
\newtheorem{definition}{Definition}
\newtheorem{property}{Property}

\theoremstyle{plain}
\newtheorem*{theorem}{Theorem}
\newtheorem*{lemma}{Lemma}
\newtheorem*{proposition}{Proposition}
\newtheorem*{corollary}{Corollary}

Use \qed (from amsthm) to close proofs.

Code Listings

ECOOP papers typically include object-oriented code (Java, Scala, Kotlin, etc.):

% Inline code:
The method \lstinline!getInstance()! implements the singleton pattern.

% Code blocks:
\begin{lstlisting}[language=Java, caption={Singleton implementation}, label={lst:singleton}]
public class Singleton {
    private static volatile Singleton instance;

    public static Singleton getInstance() {
        if (instance == null) {
            synchronized (Singleton.class) {
                if (instance == null) {
                    instance = new Singleton();
                }
            }
        }
        return instance;
    }
}
\end{lstlisting}

Figures and Tables

• Use vector formats (.pdf) where possible
• Ensure figures are legible in grayscale
• Number figures and tables sequentially
• Captions should be descriptive and self-contained

References (natbib)

ACM-Reference-Format bibstyle with author-year citations:

\bibliographystyle{ACM-Reference-Format}
\bibliography{references}

% Citations:
\citet{smith2023}      % Smith et al. (2023)
\citep{smith2023}      % (Smith et al. 2023)

Each reference must list all authors — do not use "et al." in the bibliography.

Formatting Rules

• Format: ACM sigplan (two-column, single-spaced)
• Paper size: US Letter
• Margins: Top/bottom 1in, sides 0.75in, column gap 0.25in
• Body font: 9pt minimum, Times New Roman
• References: 8pt, no page limit
• Line spacing: Single-spaced (template default)

Submission Checklist

• 12 pages or fewer (main body)
• \documentclass[sigplan,review,anonymous]
• All author/anonymization info removed
• No self-identifying URLs or citations
• PDF metadata cleared
• References list all authors
• Figures legible in grayscale
• Compiles with pdflatex

Camera-Ready Checklist

• Remove review and anonymous options
• Add \setcopyright{acmlicensed} (or appropriate)
• Fill \acmConference, \acmISBN, \acmDOI, \acmPrice
• Restore author names and affiliations
• Include page numbers (\settopmatter{printfolios=true})
