Tarring files with Elm
summary
A small Elm library, elm-tar, actually encodes a list of files (text or binary) into a single tar archive using elm/file and elm/bytes and emits properly aligned 512‑byte blocks with headers, octal size fields and an 8‑byte checksum. Create-archive works; extract-archive initially left trailing nulls and needed fixes (debugged with GNU tar as control and a hex editor). The tar format requires two null 512-byte blocks to end and compression is not yet implemented.
