Diffs - tty7

Opening one

From	How
The sidebar	Click a row’s `+N −M` counts
Source Control	Open Changes on a file, or click the row
History	Click a file inside a commit’s detail view

A diff docks beside the terminal, in the same column an open file uses, so the pane you were reading stays on screen. Esc closes it, and its header right-clicks to a menu that fills the window with it if you prefer that — more about the column →

The tty7 diff overlay — Placeholder — screenshot: the diff overlay, side-by-side, several files

Side-by-side or unified

Toggle Unified / Side-by-Side Diff in the command palette switches between the two. The choice is global — one setting for every diff, the same call VS Code’s diffEditor.renderSideBySide makes — and persists as diff_view in config.json.

What it shows

Every changed file, with its status and +N −M
Untracked files as a preview of their contents, up to 4 MB — past that the card says the read failed rather than showing a silently cut-off file
A commit’s files, when the diff came from the history

Two limits keep a huge diff from becoming a huge wait:

Limit	Value	What happens
Files rendered	300	”… and N more changed files — run git diff in the terminal to see them.”
Lines before auto-collapse	400 per file	Big files start collapsed; expand the ones you care about

Both are stated in the overlay when they apply — nothing is dropped silently. If you would rather the sidebar’s counts not be clickable, turn off Settings → Window & Tabs → Open diff preview from sidebar counts (sidebar_diff_preview: false). The branch and counts stay on the row; they just stop opening the overlay.
