Core Engine

Blazing Fast Performance

Rust core tuned for large trees and repeated comparisons.

  • Parallel directory traversal
  • Persistent hash cache
  • Parallel hash computation for batches
  • Optional hash verification controls

Flexible Comparison Controls

Tune the comparison behavior for your workflow and data shape.

  • Gitignore pattern support
  • Custom ignore patterns
  • Columns mode and status filters
  • Follow-symlink toggle
  • Diff-only and hide-* output filters

VFS, Archives, and Remote

Unified source abstraction for local, archive, and remote comparisons.

  • ZIP, TAR, TAR.GZ, TGZ, and 7Z
  • RAR read-only support
  • S3/S3-compatible endpoints
  • WebDAV and SFTP backends
  • Archive-aware file access commands

Specialized Diff Modes

Use file-type specific engines when generic byte comparison is not enough.

Text Comparison

Rule-based text normalization and line-level diffing.

  • --text-diff mode
  • Whitespace modes: all/leading/trailing/changes
  • Case-insensitive comparison option
  • Regex rule pipeline for normalization

Image Comparison

Pixel-level comparison with optional metadata awareness.

  • --image-diff mode
  • Pixel tolerance control
  • Optional EXIF comparison
  • Side-aware reporting in CLI and GUI workflows

Structured Data Formats

Schema-aware and structure-aware comparison for analytics workloads.

  • CSV row/column analysis
  • Excel sheet/cell comparison
  • JSON and YAML path-based diff
  • Parquet schema and row-level checks

Binary and Hex Views

Byte-level inspection paths for opaque file formats.

  • Hex-friendly compare workflows
  • Binary mismatch ranges in diff-file mode
  • Large-file aware output limits
  • Useful for firmware and artifact validation

Interfaces and Integrations

Pick the surface that fits your users and deployment environment.

CLI (`rcompare_cli`)

  • Subcommands: scan, sync, copy, diff-file, read
  • Machine-friendly JSON output
  • Scripting-ready behavior for CI pipelines

Slint GUI (`rcompare_gui`)

  • Native Rust desktop frontend
  • Folder, text, image, and hex workflows
  • Copy-oriented reconciliation actions

PySide6 GUI (`rcompare_pyside`)

  • Multi-session tabs and persistent profiles
  • Session-aware compare and sync dialogs
  • Desktop workflow parity with power-user tools

C FFI (`rcompare_ffi`)

  • libkomparediff2-compatible C API
  • Patch parse/apply/unapply/serialize operations
  • Static library artifacts for C/C++ integration

CLI Status Symbols

Interpret scan results quickly in terminal and reports.

Symbol Meaning
== Files are identical
!= Files are different
<< File exists only on the left side
>> File exists only on the right side
?? Same size but not hash-verified

Quick CLI Examples

# Full directory scan rcompare_cli scan /left /right --diff-only # Planned synchronization (dry run) rcompare_cli sync /left /right --direction bidirectional --dry-run --json # Diff one file path with text options rcompare_cli diff-file /left /right --path config/app.yaml --mode yaml --json # Copy selected paths from left to right rcompare_cli copy /left /right --direction left_to_right --path src/main.rs --path Cargo.toml
