Abstract
The International Workshop on Smalltalk Technologies (IWST) is traditionally organized within the European
Smalltalk User Group (ESUG) conference. Its goal is to create a forum around contributions and experiences on
building or using technologies related to Smalltalk and its derivatives. IWST welcomes papers on any aspect of
Smalltalk, from the theoretical as well as practical perspective, including research and industrial papers. IWST
2024 has received 14 submissions that passed through a 2-round reviewing process. Authors of all submissions
have been invited to present their work as a factor in the evaluation process. Finally, 10 papers were accepted for
publication in the IWST 2024 Proceedings.

1. Preface
This volume contains papers presented at IWST 2024, the International Workshop on Smalltalk Tech-
nologies, which was held in Lille, France, from July 8th to 11th, 2024.
IWST 2024 continues the tradition of a successful series of events co-located with the European
Smalltalk User Group (ESUG) conferences focused on contributions and experiences in building and
using Smalltalk Technologies. It aims to gather developers and users of Smalltalk-related technologies
around the presentation, discussion, and dissemination of the latest scientific and practical achievements
in research or industry. The workshop welcomes position papers, papers describing work in progress,
tool demonstration papers, technical and industrial reports, and papers designed to provoke debate and
inspire future collaborations and contributions.
The IWST 2024 workshop consisted of five technical sessions split into two days with contributions
reviewed and selected by an international program committee. IWST 2024 has received 14 submissions
that have been presented as a part of the contribution evaluation process. Evaluation has further been
done based on the opinion of at least three reviewers in a 2-round reviewing process. After the second
review round, 10 papers were accepted for publication in the IWST 2024 Proceedings.
Evaluation has been conducted according to several criteria. Among these criteria, we included three
award criteria: quality and significance of the scientific contribution, the significance of the contribution
to the ESUG community, and the significance and innovativeness of the emerging idea. After all, in each
category, the three best contributions received an award (Section 2.1) and a symbolic prize sponsored
by Lam Research Corporation.
We are grateful to all PC members (Section 3.2) for submitting careful and timely opinions on the
papers. Our special thanks are also addressed to the ESUG board for co-locating and co-organizing
IWST with the ESUG conference, while we thank the INRIA Lille, France for hosting and organizing
both events. Finally, a special thanks goes to the Lam Research Corporation for sponsoring the best
paper awards.
2. Workshop Program
The workshop accepted 8 full papers and 2 short papers. Papers were awarded based on three criteria
selected by reviewers: best paper, best community contribution, and best emerging idea.
