Hunk Lens

Keep the selected split-diff row visible at the bottom of Hunk, with the old version above the new version.

_{Prefer a still? See the screenshot.}

Install

Hunk 0.19 or newer can install the extension directly from GitHub:

hunk extension install modem-dev/hunk-lens

New Hunk sessions load it automatically.

Use

Open a split review as usual:

hunk diff --mode split

The lens occupies three rows at the bottom of the review and follows Hunk's current-line marker. Use Extensions → Toggle current-line lens to hide or restore it.

The lens stays out of the layout when current-line paint is unavailable, including stacked layout, a disabled current-line marker, and alternate file presentations.

Manage

hunk extension update hunk-lens
hunk extension remove hunk-lens

Pin a release when you want updates to stay on a specific version:

hunk extension install modem-dev/hunk-lens@v0.1.0

Develop

Hunk serves React, OpenTUI, and hunkdiff/extension at runtime. This repository keeps them as development-only dependencies and ships TypeScript source directly—there is no build step.

bun install
bun run check
hunk diff --mode split --extension /path/to/hunk-lens

See Hunk's extension guide for the public API and trust model.
