Current Status

rars covers the RAR lineage from early RE~^ archives through RAR 7, compression and decompression. It’s not fast, but it works. ish.

CLI

Inspect, test, and extract archives:

rars info archive.rar
rars test archive.rar
rars x archive.rar out/

Create archives with specific RAR generation:

rars a --format rar29 archive.rar files...
rars a --format rar50 --solid --auto-filter archive.rar files...
rars a --format rar70 --store --volume-size 10m archive.part1.rar files...

The writer supports stored and compressed members, split volumes, passwords, header encryption where implemented, comments, RARVM filters, RAR5 quick-open records, and supported recovery records. Run rars --help for the exact option set.

Development

Run the test suite:

cargo test --workspace --all-targets

Generate a local coverage report:

rustup component add llvm-tools-preview
./scripts/coverage.py

The script prints a line-coverage summary, saves it to target/coverage/summary.txt, and writes HTML output to target/coverage/html/library/index.html and target/coverage/html/cli/index.html.
