#base32 for moonx

base32 encodes or decodes a file or standard input using the RFC 4648 uppercase alphabet (A-Z and 2-7). It is implemented in pure MoonBit and has the same byte-oriented behavior on Native and Wasm.

This documents the cli/base32@0.1.0 candidate. It is not published until the release gate and exact MoonX acceptance pass.

printf 'foo' | moonx cli/base32
printf 'MZXW6===' | moonx cli/base32 -d
moonx cli/base32 -w0 input.bin

The supported options are -d/--decode, -i/--ignore-garbage, and -w COLS/--wrap=COLS. Encoding wraps at 76 columns by default. -w0 disables wrapping and the final newline. Decoding accepts line feeds between groups; the GNU alphabet is uppercase only, and with -i, other bytes outside the alphabet are ignored. Exactly one file operand is accepted; - or no operand reads standard input. Complete decoded groups are written immediately, so a later malformed group can leave a valid prefix on stdout.

Invalid padding, incomplete groups, and invalid wrap sizes are errors and return status 1 or 2 for argument errors. As in GNU coreutils, non-zero unused tail bits are accepted during decoding.
