Hunk Diff Context

A Hunk extension that shows the selected file in a pinned sidebar.

Install

Requires Hunk 0.19.0 or later.

hunk extension install astwys/hunk-diff-context

For a one-off local test:

hunk diff --extension .

Usage

Press Ctrl+O to open, switch, or close the right-side pane:

• With the pane closed, it opens the selected file and hunk.
• With the pane open, pressing Ctrl+O on the same hunk closes it.
• Pressing Ctrl+O on another file or hunk replaces the pinned sidebar contents.

The sidebar stays pinned while you navigate. Selection changes alone do not update it.

Keyboard shortcut

The default shortcut is Ctrl+O. Remap it in Hunk's [keybindings] configuration, in ~/.config/hunk/config.toml or .hunk/config.toml:

[keybindings]
"hunk-diff-context.toggle-diff-context" = "ctrl+shift+o"

Set the value to false to disable the command.

The sidebar renders a complete, syntax-highlighted unified diff, including unchanged, added, and removed lines.

When to use this extension

Hunk's z shortcut changes the primary review view. This extension keeps the normal Hunk view visible and adds a pinned complete-file diff beside it:

Hunk z	Hunk Diff Context
Changes the primary review view	Adds a right-side pane
Uses the current review position	Pins the selected file and hunk
Replaces the current view temporarily	Keeps Hunk's files pane and hunk view intact
Shows the file in Hunk's normal view	Shows a complete unified diff with unchanged lines

Development

pnpm install
pnpm test

pnpm dev runs hunk diff --extension . against the local checkout.
