#curl

Pure-MoonBit curl 8.22 migration. The Phase 2 HTTP/HTTPS slice streams to stdout by default and supports multiple URLs, -s/-S, -f status 22, -o, -O/-OJ, -L, --max-redirs, -I, repeated -H, the supported -X methods, repeated -d/--data-raw/--data-binary/ --data-urlencode, -T, retries, --connect-timeout, -m/--max-time, proxy/--noproxy, -k, and --remove-on-error.

Retry delay and retry-window values use upstream integer-second grammar and are bounded by the millisecond timer range (2147483 seconds). Connection and total timeouts accept decimals; zero selects curl's disabled/default behavior.

curl does not follow redirects unless -L is present. -s suppresses the meter and errors; -sS restores errors only. The meter never shares a terminal with a body written to terminal stdout, and redirected stderr receives bounded newline output rather than carriage-return spam. Failed fixed-length transfers are detected; --remove-on-error removes a partial output file.

The command remains partial, not fully curl-compatible. Arbitrary extension methods, byte-exact raw response-header/version display, compressed/HTTP2 negotiation controls, config/auth/cookie features, retry-after/backoff parity, and curl's non-HTTP protocol families are not yet implemented. -X is limited to GET, HEAD, POST, PUT, DELETE, CONNECT, OPTIONS, TRACE, and PATCH by the closed public HTTP method enum and rejects other values before network side effects.
