LIVE · Workshop on Live Programming

LIVE 2021 Workshop

The Seventh Workshop on Live Programming (LIVE 2021) took place online and in Chicago on October 19 in conjunction with SPLASH 2021. Talk recordings are on YouTube.


The following works constitute the proceedings for LIVE 2021, the Seventh Workshop on Live Programming.

Instadeq: A Live Programming Environment for End User Data Analysis and Visualization Mariano Guerra, Javier Dall' Amore Data literacy is the ability to read, understand, create, and communicate data as information. Gartner defines a citizen data scientist as “a person who creates or generates models that leverage predictive or prescriptive analytics, but... more

Modifiable Software Systems: Smalltalk and HyperCard Josh Justice When software doesn’t fully meet the needs of its user, what are the user’s options? For commercial software, the user can lobby the manufacturer for the feature they need—but the manufacturer... more

Peer-to-peer Syncing and Live Editing of Shared Virtual 3D Spaces: Challenges and Opportunities Edward Misback, Steven L. Tanimoto As groundwork for a virtual live programming collaboration environment, we built a peer-to-peer network of devices designed for 2D and 3D interactions that independently host, edit, and sync the state of a virtual space in.... more

Enhancing Liveness with Exemplars in the Newspeak IDE Gilad Bracha Traditional program editing tools are separate from program evalution tools. Exceptions are debuggers as well as REPLs and similar tools such as Smalltalk workspaces and object inspectors, or computational... more

LIVE 2021 Call For Submissions

The LIVE 2021 workshop invites submissions of ideas for improving the immediacy, usability, and learnability of programming. Live programming gives the programmer immediate feedback on the behavior of a program as it is edited, replacing the edit-compile-debug cycle with a fluid programming experience. The best-known example of live programming is the spreadsheet, but there are many others.

Submission Guidelines

LIVE welcomes demonstrations of novel programming systems, experience reports, literature reviews, demos of historic systems, and position papers. Topics of interest include:

  • live programming environments
  • visual programming
  • structure-aware editors
  • advances in REPLs, notebooks, and playgrounds
  • programming with typed holes, interactive programming
  • programming by example/demonstration
  • bidirectional programming
  • debugging and execution visualization techniques
  • language learning environments
  • alternative language semantics or paradigms in support of the above
  • frameworks for characterising technical or experiential properties of live programming

LIVE provides a forum where early-stage work will receive constructive criticism. Submissions may be short papers, web essays with embedded videos, or demo videos. A written 250 word abstract is required for all submissions. Videos should be up to 20 minutes long, and papers up to 6 pages long. Use concrete examples to explain your ideas. Presentations of programming systems should take care to situate the work within the history of such tools.

While LIVE welcomes early work and exploratory work, authors may optionally choose to have their work considered for inclusion in the workshop proceedings.
