TL;DR
A developer has released Edsger, a handwritten Clojure REPL for the reMarkable 2 tablet, showcased on Show HN. The project enables handwritten input for Clojure code execution, aiming to enhance programming on e-ink devices.
A developer has launched Edsger, a handwritten Clojure REPL designed specifically for the reMarkable 2 tablet, and showcased it on Hacker News Show HN. The project allows users to write Clojure code by hand on the device and execute it interactively, representing a novel approach to programming on e-ink devices.
Edsger is an open-source project that enables handwritten input for a Clojure REPL on the reMarkable 2, a popular e-ink tablet known for note-taking and limited programming capabilities. The developer, Daniel Janus, demonstrated the tool on Show HN, emphasizing its ability to interpret handwritten Clojure code and execute it directly on the device.
The implementation leverages handwriting recognition technology integrated with Clojure’s REPL environment, allowing users to write code with a stylus and see immediate results. The project aims to improve the programming experience on devices that traditionally lack a keyboard or mouse, especially targeting developers and enthusiasts interested in portable coding solutions.
Why It Matters
This development is significant because it pushes the boundaries of what is possible on e-ink devices like the reMarkable 2, which are typically used for note-taking rather than coding. By enabling handwritten Clojure REPL interaction, Edsger could inspire new workflows for developers who prefer writing by hand or need portable coding environments, especially in contexts where traditional hardware is impractical.
Additionally, this project highlights the growing interest in combining handwriting recognition with programming environments, potentially influencing future tools for coding on tablets or other limited-input devices. It also demonstrates the creative use of existing hardware for new purposes, expanding the device’s utility beyond its original design.

Background
The reMarkable 2 has gained popularity for its paper-like display and focus on note-taking, with limited native support for programming. Previous efforts to run code or develop software on the device have involved remote access or workarounds. The introduction of a handwritten Clojure REPL marks a novel approach, building on advances in handwriting recognition and functional programming.
Daniel Janus previously shared other projects related to handwriting recognition and programming tools, but Edsger is notable for its focus on interactive Clojure development directly on the device. The project was posted on Show HN, a platform for showcasing new projects and prototypes, indicating its experimental and early-stage nature.
“Edsger transforms the reMarkable 2 into a portable Lisp environment, making handwritten coding practical and fun.”
