# bf-2pw: Emitter Implementation Verification
|
|
|
|
## Status: COMPLETE
|
|
|
|
Implementation was completed in commit `bfb50da` on 2024-06-10.
|
|
|
|
## Implementation Summary
|
|
|
|
`src/emitter.rs` provides three output format handlers:
|
|
|
|
### Text Format (`OutputFormat::Text`)
|
|
- Writes response text to stdout with trailing newline
|
|
- Error messages go to stderr only
|
|
|
|
### JSON Format (`OutputFormat::Json`)
|
|
- Single-line JSON result object to stdout
|
|
- Fields included:
|
|
- `type`: "result"
|
|
- `subtype`: "success" or error subtype
|
|
- `is_error`: boolean
|
|
- `result`: response text (success) or omitted (error)
|
|
- `session_id`: optional session identifier
|
|
- `num_turns`: turn count
|
|
- `duration_ms`: session duration
|
|
- `cost_usd`: cost (currently 0)
|
|
- `claude_version`: Claude Code version
|
|
- `usage`: token counts (input, output, cache_creation, cache_read)
|
|
|
|
### Stream-JSON Format (`OutputFormat::StreamJson`)
|
|
- Reader thread spawned via `spawn_stream_json_reader()`
|
|
- Forwards JSONL transcript lines to stdout in real-time
|
|
- Supports graceful shutdown via `drain_tx` channel
|
|
- Handles missing file with retry loop
|
|
|
|
### Error Reporting
|
|
- `emit_error()` handles both JSON and text modes
|
|
- JSON mode writes to stdout, text mode to stderr
|
|
- Exit codes: Setup(2), Timeout(124), Interrupted(130), AssistantError(1)
|
|
|
|
## Test Coverage
|
|
|
|
All 13 tests pass:
|
|
- Text format: trailing newline, no extra whitespace
|
|
- JSON format: all required fields present, integers for usage
|
|
- Error handling: correct is_error, subtype, exit codes
|
|
- Stream-json: line parsing, disconnect handling
|
|
|
|
