Positron Go

November 1, 2025 · View on GitHub

Positron Go is a Positron extension that wires the gonb kernel into Positron so you can run Go notebooks alongside your Python and R work.

Features

  • Detects when the extension is running inside Positron and surfaces Go-specific messaging
  • Adds the command Run Go sample in Positron to quickly validate your gonb setup
  • Uses the Positron runtime API to execute Go code through gonb without leaving the editor

Prerequisites

  • Go
  • The gonb Jupyter kernel installed and available on your PATH
  • Positron 2025.6.x or newer
  • Install the positron-go extension within Positron

Verify that gonb is installed:

go install github.com/janpfeifer/gonb@latest && \
  go install golang.org/x/tools/cmd/goimports@latest && \
  go install golang.org/x/tools/gopls@latest

// it's actually `$HOME/go/bin/gonb` if that directory is not on your PATH 
gonb --version

Install the positron-go extension.
