com-lihaoyi/Ammonite

Ammonite is a Scala REPL and scripting environment that provides an interactive development and execution platform for Scala code. It supports both interactive sessions and headless script execution, featuring a modular architecture that separates the compiler interface, interpreter logic, and terminal handling. The system enables users to run Scala scripts with dynamic dependency resolution, manage session state, and integrate with external build tools via the Build Server Protocol. Additionally, it offers remote access capabilities through an SSH server and maintains compatibility across multiple Scala versions.

This period focused on restructuring the codebase into distinct, modular components such as the SSH REPL, compiler interface, and terminal input handling, while simultaneously migrating the build system to Mill. The team also significantly expanded the test coverage for script execution, error handling, and integration scenarios to support the new architecture.

This period focused on exposing the Ammonite interpreter through a public InterpAPI and implementing a Build Server Protocol (BSP) server to enable IDE and build tool integration. The work involved refactoring the interpreter's internal logic, introducing stub packages for magic imports, and adding extensive test coverage for the new features and error handling.

This period focused on restructuring the compiler integration to support multiple Scala 2.x versions and introducing a new interface module for REPL code compilation. It also added initial support for Scala 3 by creating version-specific source directories and helper classes, while refactoring the main entry point to separate command-line logic from the core runner.
