- Stream mode now parses SSE events, hex-decodes .data.audio, and writes raw binary MP3 to stdout (fixes --stream example piping to mpv) - Add EPIPE handler to main.ts so piping to a downstream process that exits early (e.g. mpv, head) no longer crashes with unhandled error Fixes MiniMax-AI#54 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Two fixes for
mmx speech synthesize --stream:1. SSE stream now outputs decoded binary audio
--streamwas writing raw SSE/JSON/hex text to stdout. It now:parseSSE().data.audio(hex string) from each event's JSONThis makes the documented example actually work:
2. EPIPE no longer crashes the process
Added
stdout.on('error')handler inmain.ts. When a downstream process (e.g.mpv,head) exits early and closes the pipe,EPIPEis now treated as normal pipe-close with exit code 0, instead of an unhandled exception that crashes the CLI.Before:
Error: write EPIPE— unhandled, process exits with non-zero codeAfter: exit code 0
Fixes #54
Test plan
mmx speech synthesize --text "Test" --stream | head -c 4— first bytes should beID3(valid MP3)mmx speech synthesize --text "Test" --stream | head -c 1; echo $?— should print0mmx speech synthesize --text "Test" --out /tmp/out.mp3— non-stream path unchanged🤖 Generated with Claude Code
