What's New in v0.19.4

v0.19.4 is a review editor release. Six PRs bring a new diff type for reviewing entire repos, a code file viewer with syntax highlighting and annotation support, per-file quick-settings for diff display, and a hide-whitespace toggle that matches GitHub's ?w=1 behavior.

"All Files" Diff Type

Sometimes you want to review an entire repository, not just uncommitted changes. The new "All files" diff type diffs the empty tree against HEAD, showing every tracked file as an addition. This is useful when a repo has no working tree changes but you still want to launch a review, or when you want to browse the full codebase through the review UI.

The option appears in the diff type dropdown alongside the existing choices and can be set as the default preference in the setup dialog or config.

Code File Viewer with Syntax Highlighting and Annotations

Clicking a code file link (.ts, .py, .go, etc.) in a plan or annotated document now opens a read-only dialog with full syntax highlighting. The server runs preloadFile from @pierre/diffs/ssr to return pre-rendered HTML, so there's zero client-side Shiki cost and the file renders instantly.

The viewer supports line-level annotations: click the gutter button on any line, select a line range, or drag across text to add a comment. Annotations appear in the sidebar panel alongside prose annotations and are included in exported feedback. Draft recovery covers code file annotations as well, so nothing is lost if the server restarts.

Under the hood, the dialog uses a new reusable PopoutDialog component extracted from the table popout, which also fixes the table popout's missing backdrop blur.

Hide Whitespace

A new toggle suppresses whitespace-only changes in diffs, matching GitHub's ?w=1 / git diff -w behavior. When enabled, re-indentation, alignment padding, and interior whitespace changes are removed from the diff, leaving only substantive code changes visible. The implementation normalizes all whitespace runs to a single space before diffing, so interior whitespace changes like alignment shifts and extra spaces between tokens are correctly suppressed.

The toggle is available in the per-file quick-settings popover and in the global settings dialog. Default: off.

Quick-Settings Popover

Each file header in the review editor now has a gear icon that opens a compact popover with all diff display options: style (split/unified), overflow mode, change indicators, inline diff granularity, line numbers, diff background colors, and hide whitespace. This provides quick per-file access to display options without opening the full settings dialog.

Additional Changes

• Gutter hover button fix: The + button for adding line comments wasn't rendering because Pierre updates hover state imperatively (no React re-render). The button now always renders and checks hover state at click time. Button styling was also updated to match Pierre's theme spec. — #630
• @pierre/diffs 1.1.20: Picks up split-view scroll fix, WorkerPool race condition fix, hydration fixes, CSS refactoring, and empty-file-as-deleted fix. — #630
• File tree expand toggle: The separate expand-all and collapse-all buttons are replaced with a single toggle. Shows the collapse action when all folders are expanded, otherwise shows expand. Disabled when the tree has no folders. — #633
