almond-sh/almond

Almond is a Jupyter kernel implementation for Scala that provides an interactive computing environment within Jupyter notebooks. It supports both Scala 2 and Scala 3, offering features such as rich output rendering, reactive variable updates, and code completion. The system manages kernel lifecycle, handles asynchronous execution, and integrates with the Jupyter protocol to deliver a robust interactive programming experience.

This period focused on modernizing the Almond kernel's architecture by migrating the build system to Mill and refactoring the core interpreter and kernel modules to support asynchronous operations and reactive updates. The team removed legacy Jupyter and SBT components while introducing a modular, thread-safe design with improved JSON serialization and logging, accompanied by comprehensive test coverage.

This period focused on modernizing the Almond kernel with full Scala 3 support and a comprehensive new Jupyter API for kernel developers. The team also overhauled the display system to support rich output formats and improved the Scala interpreter with features like compile-only mode and enhanced code inspection.

The project migrated its build system to Mill 1.0 and introduced a two-step kernel startup mechanism to improve lifecycle management. This period also added experimental support for Toree-style magics, Jackson-based JSON serialization, and custom directive groups, while updating the Scala interpreter to version 3.4.2.
