Diff Plus

nfourCode & Reviews
Get it for macOS

See where a large change lands before you read it: a folder tree beside BB's Diff tab with file counts and +/- per folder. Click a folder to show only its files, or a file to open its diff alone, through the tab's own filter, so Viewed marks, split view and Add to chat keep working. Files and folders carry vscode-icons glyphs and VS Code's git letters, with a dot on each folder for what changed under it. The tree follows the tab's scope, from all changes down to one commit, and moves above the list on narrow screens. It finds the Diff tab by its page structure, which is not a documented interface, so a BB update may need a plugin update. Requires BB 0.48 or later.

What you get

A folder button in the toolbar of BB's Diff tab shows the changed files as a tree beside the file list. Each folder shows how many files changed under it and its added and removed lines, so you can see where a large change lands before you read any of it.

  • Click a folder's name to show only the files under it. Click a file to show it alone with its diff open. Click the same row again, or All files, to see everything.
  • Click a folder's icon to open or close it. The tree opens the top levels for you.
  • Files and folders carry vscode-icons glyphs for common languages, tools and folder names, and VS Code's git letters at the right: U untracked, A added, M modified, D deleted, R renamed. A folder gets a dot: green when everything under it is new, red when it is all deleted, amber otherwise.
  • The tree follows the tab's scope: all changes, committed changes, uncommitted changes or a single commit. It refreshes when BB reports that the worktree's status or branches changed.

Layout

Drag the tree's right edge, or focus it and use the arrow keys, to change its width. In a tab narrower than 600px, such as the phone drawer, the tree goes above the list instead. The folder button hides the tree, and the choice and the width are kept per browser.

How it works

The tree adds to BB's own Diff tab and leaves its diffs alone: filtering goes through the tab's own filter box, so BB's own file search and filters, Viewed checkboxes, split view and "Add to chat" on selected lines all keep working. File paths that look like glob patterns, such as app/[slug], are escaped so a click shows exactly that folder or file.

Requirements

  • BB 0.48 or later.
  • BB has no plugin slot beside the Diff tab, so the tree finds the tab by its page structure. A future BB release may move it; the tree then does not show until the plugin is updated.
  • It reads the changed files from BB's bundled Git plugin, which the Diff tab itself uses.
  • No external service or account is used.
  • The icons are from vscode-icons, under CC BY-SA 4.0: https://github.com/vscode-icons/vscode-icons

Chat DockWrite your next message beside the diff, file or tab you are reading: the composer moves into the right panel while it is open. Your draft and the cards above the box (running commands, child threads, questions) move with it and go back under the timeline when you close the panel. Dock it as a strip under whichever tab is open, or as a Chat tab of its own that splits and drags like any other. Split chat panes keep a composer each, and on a phone it docks at the bottom of the panel drawer. It moves BB's own page elements, which are not a documented interface, so a BB update may need a plugin update. Requires BB 0.48 or later.NewPinned TurnsKeep the question you are reading under and the agent's last answer in view while you scroll a long thread. Click either one to jump back to it; the page's address and the back button stay as they were. A counter such as 7/23 shows which turn you are on, and a turn that is still running pulses. A Pinned turns submenu in the thread's actions menu switches the bar and each option on or off. It reads BB's timeline layout, which is not a documented interface, so a BB update may need a plugin update. Requires BB 0.48 or later.New
