cat <<'USAGE'
|
|
Usage: showcase diff-logs <slug> --since <time> [options]
|
|
|
|
Show container logs for a specific time window. Useful when running
|
|
tests repeatedly — see only logs from the last run, not the full
|
|
container lifetime.
|
|
|
|
Options:
|
|
--since <time> Start of window (required). Accepts:
|
|
Duration: 10m, 1h, 30s
|
|
Timestamp: 2024-01-15T10:30:00
|
|
Special: "last-test" (reads .last-test-ts marker)
|
|
--until <time> End of window (default: now)
|
|
--grep <pattern> Filter output (regex, e.g. "fixture|match")
|
|
|
|
Examples:
|
|
showcase diff-logs aimock --since 5m
|
|
showcase diff-logs mastra --since 10m --grep "error|warn"
|
|
showcase diff-logs aimock --since last-test
|
|
showcase diff-logs aimock --since 10:30:00 --until 10:35:00
