lzfsec

A pure-Go CLI wrapper around go-compressions/lzfse — Apple’s LZFSE / LZVN compression formats on the command line. Repository →

Commands

lzfsec [-v] compress   [-i input] [-o output]
lzfsec [-v] decompress [-i input] [-o output]

• -i / --input defaults to stdin.

• -o / --output defaults to stdout.

• -v / --verbose (persistent) prints a summary line to stderr with byte counts, compression ratio (for compress), and elapsed time:

  compressed 65536 → 12345 bytes (18.8%) in 4.231ms
  decompressed 12345 → 65536 bytes in 1.872ms

  Without -v both sub-commands stay silent so the binary output on stdout is safe to pipe.

Examples

# Compress a file to disk.
lzfsec compress -i big.bin -o big.bin.lzfse

# Round-trip through a pipe.
cat big.bin | lzfsec compress | lzfsec decompress > restored.bin

# Show timing + ratio.
lzfsec -v compress -i big.bin -o big.bin.lzfse

Build

go build ./cmd/lzfsec        # or: task build

Coverage

task test reports 100% statement coverage (cover.out) across the four sub-packages:

The package ships a Taskfile (task lint|build|test|ci) used by both local development and CI; Renovate auto-merges patch/minor gomod updates.
