Version 1.1.0 | Status: Production Ready | Apple/macOS Support: ✅ Complete
GLifzip is a modern, high-performance compression format designed for GlyphOS that achieves 10-100× faster compression and decompression than Windows/macOS ZIP through multi-threaded Zstd compression and LZ4 decompression.
Now with full native Apple/macOS support, extended attributes preservation, and Apple Silicon optimization.
- Multi-threaded Compression: Zstd-based compression with linear core scaling (≥1 GB/s per core target)
- Ultra-fast Decompression: LZ4-based decompression (≥2 GB/s per core target)
- Apple Silicon Optimized: Native arm64 support with dedicated optimizations
- Deterministic Builds: Bit-for-bit identical outputs across all platforms
- Cryptographic Verification: SHA256 hashing for payload and archive integrity
- Symbolic Metadata: JSON sidecars capture transformation intent
- Extended Attributes: Preserves macOS xattr, permissions, and timestamps
- Cross-platform: Windows, Linux, and macOS (Intel & Apple Silicon)
- macOS Native: Finder integration, file type registration, Gatekeeper support
- Directory Compression: Archive entire directories with metadata preservation
- Exclude Patterns: Flexible file filtering with glob patterns

glifzip create data.bin -o data.glif --level=3 --threads=8Options:
--level=N: Compression level 1-22 (default: 8)--threads=N: Number of threads (default: auto-detect)

# Example output:
# Archive verified successfully!
# Payload size: 1000000 bytes
# Archive size: 350000 bytes
# Compression ratio: 35.00%
# Compression level: 8
# Threads used: 8GLifzip can also be used as a Rust library:
use glifzip::{compress, decompress, CompressionConfig};
// Compress data
let data = b"Hello, GLifzip!";
let config = CompressionConfig::default();
let compressed = compress(data, &config)?;
// Decompress data
let decompressed = decompress(&compressed, config.threads)?;
assert_eq!(data, decompressed.as_slice());GLifzip uses the .glif file format with the following structure:
GLIF01 Header (116 bytes)
├─ Magic Number: "GLIF01"
├─ Version: 1.0
├─ Payload Size (uncompressed)
├─ Archive Size (compressed)
├─ Payload Hash (SHA256)
├─ Archive Hash (SHA256)
├─ Compression Level
├─ Decompression Mode (0=LZ4, 1=Zstd)
├─ Cores Used
├─ Timestamp
└─ Sidecar Size
Symbolic Sidecar (JSON)
└─ Metadata about compression, hashes, platform
Compressed Payload
└─ Multi-threaded Zstd → LZ4 wrapped data
