mine / coalton / common lisp

A new IDE called Mine targets Coalton and Common Lisp, aiming to recreate the simple, approachable experience of classic BASIC and Borland Turbo-era tools. Announced on the Coalton project site and shared on Hacker News, Mine positions itself as an easy-to-use development environment for Coalton (a typed layer on top of Racket/Typed Racket?) and Common Lisp users who want a lightweight, beginner-friendly workflow. The project matters because it lowers the barrier to entry for Lisp development, potentially attracting learners and hobbyists who miss the quick feedback loop of historical IDEs. Key players are the Coalton community and the Mine project maintainers; broader implications include improved tooling for niche Lisp ecosystems and renewed interest in minimalist IDE design.

Mine, a new cross-platform IDE for Coalton and Common Lisp, launches in two editions: mine-app (packaged, dependency-free for Windows and macOS) and mine-core (terminal-first for Windows, macOS, and Linux requiring a Unicode font and Kitty keyboard protocol). It bundles both languages, letting developers mix Coalton’s static, functional-leaning types with Common Lisp’s dynamic object system. Key features include an integrated REPL with code beaming, an interactive debugger that surfaces errors and stack traces, inline diagnostics and optimization hints, type-aware autocomplete for Coalton, and optional structural-editing lessons. All code is compiled to native CPU binaries for performance. This matters for Lisp-family developers seeking a modern, polished tooling experience across platforms.

Mine, a new cross-platform IDE for Coalton and Common Lisp, is available as a packaged mine-app for macOS/Windows and a terminal-oriented mine-core for Windows, macOS, and Linux. It bundles both languages (use either or mix them), an integrated REPL that supports beaming code from functions to projects, an interactive debugger with stack traces and quick fixes, inline diagnostics and optimization hints, and type-aware autocomplete for Coalton. The IDE includes optional structural-editing lessons to teach ParEdit-style editing quickly, and compiles code to native CPU binaries rather than relying on VMs. This matters to Lisp and functional-language developers seeking a polished, native-performance environment that combines REPL-driven workflows with modern editor features.

Mine is a new single-download IDE for Coalton and Common Lisp designed to lower the onboarding barrier and deliver a polished, discoverable Lisp development experience. Built with hot-reloading, REPL integration, inline diagnostics, an integrated debugger, jump-to-definition, package-aware autocomplete, real-time argument/type hints, structural editing lessons, and native compilation/executable building, Mine targets both beginners and experienced Lisp programmers. The project intentionally avoids extensibility, plugins, telemetry, and editor emulation (no Emacs or vi modes), favoring a simple, consistent UI and workflow to make Coalton and Lisp accessible without requiring ASDF/Quicklisp/Emacs knowledge. Its goal is to simplify the path into Lisp development rather than replace heavyweight, extensible stacks like Emacs+SLIME or commercial Lisp IDEs.
