Introducing REPL Support in Zed for Interactive Computing

Explore Zed's latest feature: a Jupyter Powered REPL for running code, visualizing data, and iterating right in your editor.

Published 4 months ago by @zeddotdev on zed.dev

Abstract

Zed introduces REPL support, merging the direct iterative experience of a REPL in your terminal with the rich output and interactivity of Jupyter notebooks. The feature allows running code line by line, block by block, or on any selection within Zed. The REPL supports various languages, including Python, TypeScript via Deno, and R via Ark or xeus-r. Users can queue up executions, iterate inline, and perform tasks like running statistics in R or plotting with D3 in TypeScript. The inline REPL is currently in preview in the latest Zed release.
