buildbot-pr-check

name	buildbot-pr-check
description	Inspect Buildbot (buildbot-nix) CI for a PR. Use to find/watch the build for a PR, list failed sub-builds with their attrs, and fetch failing log tails.

buildbot-pr-check <pr-url>                                # eval build + per-sub-build status table
buildbot-pr-check <pr-url> --watch --interval 60          # poll until complete; exit 0=success 1=failure
buildbot-pr-check <pr-url> --failures --log-tail 80       # failed sub-builds: attr, error prop, stdio log tail + log_url

<pr-url> is a GitHub …/pull/N or Gitea …/pulls/N URL (omit to auto-detect the current branch's PR via gh). The buildbot instance is discovered from the forge's commit statuses; no config. Add --json for structured output:

buildbot-pr-check <pr-url> --failures --json | jq -r '.failures[] | "\(.attr)\t\(.status)\t\(.log_url // "-")"'

Need more than the tail? log_url is a plain …/api/v2/logs/<id>/raw_inline endpoint — curl -s "$log_url" | tail -n 500 / | grep error:.
