mini_blar

A constrained subset of the blar archive format — for embedded systems, bootstrap environments, and any context where the full blar feature set (compression, encryption, codec expansion, signatures) is overkill.

mini_blar archives are valid blar archives: any blar implementation can read them. mini_blar's writer only emits a profile of the format, and its reader only handles that profile.

Built on BLIP.

Profile

mini_blar archives:

• May contain FILE and DIR entries (TYPE=5, TYPE=7)
• Use only TYPE, CSUM, VAL attributes (no COMP, ENC, SEG, SIG)
• Use only xxhash64 for content checksums
• Have no compression, no encryption, no container expansion

If you need any of those, use blar.

Build

./build         # release (via nix build)
./build debug   # debug (via zig build)
./test          # run unit + CLI tests

mini_blar and blar are sister projects. mini_blar does not depend on blar. Both depend on BLIP. The two impls share a wire-format profile, not code.
