Release v2026.02.23.33037

BlazorTextDiff v2026.02.23.33037

Breaking Changes

• Removed JavaScript interop — the component is now pure C#/Blazor. Remove the <script src="_content/BlazorTextDiff/js/BlazorTextDiff.js"></script> tag from your HTML.
• Removed DI registration — ISideBySideDiffBuilder and IDiffer no longer need to be registered. Remove any builder.Services.AddScoped<ISideBySideDiffBuilder, SideBySideDiffBuilder>() calls from Program.cs.
• DiffStats constructor changed — now accepts both (DiffPaneModel? oldText, DiffPaneModel? newText) to correctly count deletions from the old pane. Previously only accepted a single pane, causing deletion counts to always be zero.
• Removed ShowWhiteSpace parameter — this parameter no longer exists on TextDiff.

Added

• Character-level highlighting — changed lines now highlight the specific characters that differ, not just the whole line. Uses CharacterChunker from DiffPlex for true per-character diffing.
• Word + character two-tier highlights — partially changed words get a soft background (*-word class) with the specific changed characters strongly highlighted inside (*-character class). Fully changed words use the character-level class directly.
• Adjacent highlight merging — consecutive highlighted characters merge into a single smooth pill shape via CSS :has() and + selectors. Rounded corners only appear on the first and last character in a run.
• CSS custom properties for highlight shape — --diff-char-radius, --diff-char-padding, --diff-word-radius, --diff-word-padding for easy customization of highlight appearance.
• Class parameter — pass additional CSS class(es) to the root diff-container element for scoped style overrides.
• AdditionalAttributes splatting — unmatched HTML attributes (style, id, data-*, etc.) pass through to the root element.
• IgnoreCase parameter — toggle case-insensitive diff comparison.
• IgnoreWhiteSpace parameter — toggle whitespace-insensitive diff comparison.
• Interactive collapse/expand — the "..." collapse indicator is now a <button> that toggles between "▼ Show more" and "▲ Show less".
• Inline SVG loading spinner — replaced the Bootstrap-dependent CSS spinner with a self-contained SVG animation.
• Dark mode — full dark theme via @media (prefers-color-scheme: dark) with appropriate highlight colors.
• Responsive layout — panes stack vertically on narrow screens (max-width: 768px).
• Reduced motion support — @media (prefers-reduced-motion: reduce) disables transitions.
• Print styles — clean output when printing.
• Focus states — keyboard-accessible focus outlines on line numbers and badges.
• CI workflow — new .github/workflows/ci.yml runs build + test on every push and PR.
• Unit tests — 38 tests across 4 test files covering DiffStats, TextDiff, TextDiffLine, and TextDiffPane.
• Character highlight demo page — Pages/CharacterHighlight.razor showing typo corrections and code refactoring examples.

Changed

• Project structure — moved projects under src/ and tests/ directories.
• Package updates — Microsoft.AspNetCore.Components.Web 9.0.8 → 9.0.13, Microsoft.AspNetCore.Components.WebAssembly 9.0.8 → 9.0.13, DiffPlex 1.8.0 → 1.9.0.
• Publish workflow — now manual-only (workflow_dispatch). Automatic CI testing handled by the new ci.yml workflow.
• Deploy workflow — updated paths for src/ structure, added test step before build.
• Demo pages refactored — consolidated from 5 pages to 3 (Home playground, Character Highlight, Async). Removed IgnoreCaseDemo.razor, IgnoreWhitespaceDemo.razor, and SurveyPrompt.razor.
• README — complete rewrite documenting current API, all parameters, CSS custom properties table, highlight system explanation, and styling examples.

Fixed

• DiffStats deletion count — deletions are now correctly counted from the old text pane instead of always showing zero.
• CSS rgba() with custom properties — rgba(var(--diff-border-primary), 0.3) doesn't work with hex values; replaced with color-mix(in srgb, var(...) 30%, transparent).
• Loading spinner text — fixed the spinner so the text doesn't spin along with the icon.

Removed

• BlazorTextDiff.js — JavaScript file deleted; all functionality is now pure C#.
• BlazorDiff.scss — SCSS source removed; CSS is maintained directly.
• compilerconfig.json — SCSS compiler configuration removed along with related .csproj entries.
• docs/readme.md — placeholder file removed.
• SurveyPrompt.razor — unused demo component removed.
• IgnoreCaseDemo.razor / IgnoreWhitespaceDemo.razor — consolidated into the main playground page.
