DevEnv VS Code Extension

Detect environment drift in a repository before it turns into setup churn, broken onboarding, or CI surprises.

DevEnv scans common runtime and container files, highlights mismatches inside VS Code, and helps you generate a starter devenv.yaml.

What it does

• Scans .nvmrc, .node-version, .python-version, package.json, pyproject.toml, devcontainer.json, Dockerfiles, compose files, and GitHub Actions workflows
• Detects Node and Python drift across local setup, containers, and CI
• Surfaces drift warnings as diagnostics and quick fixes
• Shows environment health in the status bar
• Adds a DevEnv sidebar inspector for issues and detected signals
• Generates a starter devenv.yaml

Install

Install from the VS Code Marketplace when published, or install the packaged .vsix locally.

pnpm install
pnpm package

Then in VS Code, run Extensions: Install from VSIX... and choose the generated file.

Commands

• DevEnv: Scan Workspace
• DevEnv: Check Drift
• DevEnv: Generate devenv.yaml
• DevEnv: Fix Drift

Try it locally

Open demo-workspace to test the extension against a repo with intentional Node, Python, container, and CI drift.

Expected behavior:

• the inspector shows multiple runtime conflicts
• diagnostics appear in version and config files
• quick fixes offer a one-click alignment path
• DevEnv: Generate devenv.yaml produces a canonical starter spec

Use it

1. Open a repository in VS Code.
2. Run DevEnv: Scan Workspace.
3. Review issues in diagnostics, the status bar, and the DevEnv inspector.
4. Run DevEnv: Fix Drift or apply quick fixes where available.
5. Run DevEnv: Generate devenv.yaml to create a starter environment contract.

Develop

1. Open this folder in VS Code.
2. Run pnpm install.
3. Press F5 to launch an Extension Development Host.
4. Open demo-workspace or another repo with mixed runtime declarations.
