Fix CI logs appending instead of updating in place#21
Merged
Conversation
`gh run watch` uses ANSI cursor-up sequences (ESC[<N>A) to redraw its multi-line status block. The previous fix only handled carriage returns (\r) for single-line replacement, so each refresh appended the entire block again. - Detect ESC[<N>A cursor-up sequences in streamProcess and rewind the log by N lines before appending the new block - Strip ANSI escape sequences from log output for clean display - Add log.rewind event type so the frontend removes stale lines - Include test with mock gh-run-watch script to validate behavior Co-Authored-By: Claude Opus 4.6 <[email protected]>
