TextCompareForBlazor

TextCompareForBlazor is a lightweight, client-side Blazor (WebAssembly or Server) component for visually comparing two text blobs side-by-side with selectable diff granularity (Character / Word / Line), optional whitespace normalization, synchronized scrolling, line alignment (with gap placeholders), and customizable theming.

Framework Support

  • .NET 8.0
  • .NET 9.0
  • .NET 10.0

What's New in 1.3.0

  • Added multi-targeting: net9.0, net10.0
  • Now supports .NET 8.0, 9.0, and 10.0
  • No API changes; purely additive framework support

What's New in 1.2.2:

  • Fixed issue with selected line highlighting bleeding into gutter area.
  • fixed issue with captions shifting left when hidding line numbers.

What's New in 1.2.1

  • Minor UI polish and reliability fixes for upload buttons and search scrolling.

What's New in 1.2.0

  • Added upload buttons in captions (above gutters) for left/right panels.
  • Display File Names in captions.
  • Display �Last Modified� dates right-justified in captions.
  • Clear buttons to reset panels.
  • Caption layout and styles refined; minor UI polish.

What's New in 1.1.0

  • Collapsible unchanged regions with ellipsis rows (click to expand).
  • Collapse contiguous unchanged sections from the gutter.
  • Right-click context menu in text areas with context-aware actions:
    • Expand all collapsed regions
    • Collapse all expanded regions
  • Search improvements: case-sensitive toggle and better scroll-into-view behavior.
  • Unified font family and size across gutter and content via CSS variables.
  • Minor fixes for line number alignment and scroll sync.

What's New in 1.0.3

  • Unified font family and size applied to both gutter (line numbers) and text content via CSS variables.
  • Toolbar dropdowns for Font and Size.
  • Toolbar order: Search first, then Granularity/Whitespace, then Font; Sync toggle right-aligned.
  • Typical, widely available monospace font stacks offered by default.

Usage: Unified Font Settings

Control the font family and size for the entire compare surface (both gutters and text areas). These parameters can be set directly or via toolbar dropdowns when ShowToolbar is true.

Features

  • Side-by-side synchronized scroll viewing (toggleable)
  • Granularity selector: Character, Word, or Line
  • Word diff uses token mapping to preserve original spacing
  • Intelligent line alignment (modified / inserted / deleted handling)
  • Optional whitespace collapsing (IgnoreWhitespace)
  • Optional NBSP width preservation for deleted/inserted tokens (UseTokenPadding)
  • Line numbers (toggleable)
  • Footer metrics: lines, words, characters, differences
  • Fully styleable via parameters + CSS variable hooks
  • Accessible structure: ARIA labels, focusable line items
