# Greploop

Iteratively fix a PR/MR/CL until Greptile gives a perfect review: 5/5 confidence, zero unresolved comments.

## Inputs

- **PR/MR/CL number** (optional): If not provided, detect the PR/MR for the current branch, or the default pending changelist for p4.

## Instructions

### 0. Detect platform

First check for Perforce, then fall back to git remote detection:

```bash
# Check for Perforce environment
if p4 info >/dev/null 2>&1; then
  VCS="perforce"
else
  REMOTE_URL=$(git remote get-url origin)
  if echo "$REMOTE_URL" | grep -qi "gitlab"; then
    VCS="gitlab"
  else
    VCS="github"
  fi
fi
```

For self-hosted GitLab instances whose hostname doesn't contain "gitlab", the user can override by passing `--vcs gitlab` as an input. For Perforce, pass `--vcs perforce`.

### 1. Identify the PR/MR/CL

**GitHub:**
```bash
gh pr view --json number,headRefName -q '{number: .number, branch: .headRefName}'
```

**GitLab:**
```bash
glab mr view --output json | jq '{iid: .iid, branch: .source_branch}'
```

Switch to the PR/MR branch if not already on it.

**Perforce:**
```bash
# List pending changelists for current user/client
p4 changes -s pending -u $P4USER -c $P4CLIENT

# Describe a specific CL
p4 describe -s <CL_NUMBER>
```

Ensure the correct workspace (`p4 client`) is set before proceeding.

Key field differences:
- GitHub: `number`, `headRefName`, `headRefOid`
- GitLab: `iid`, `source_branch`, `sha`
- Perforce: changelist number, `P4CLIENT`, shelved files

### 2. Loop

Repeat the following cycle. **Max 5 iterations** to avoid runaway loops.

#### A. Trigger Greptile review

Push/shelve the latest changes (if any):

**GitHub/GitLab:**
```bash
git push
```

**Perforce:**
```bash
# Re-shelve to update the shelved files for review
p4 shelve -f -c <CL_NUMBER>
```

Wait for checks to start after push/shelve:

```bash
sleep 5
```

**GitHub** — check if Greptile is already running before posting a new trigger comment:

```bash
GREPTILE_STATE=$(gh pr checks <PR_NUMBER> --json name,state | jq -r '.[] | select(.name | test("greptile"; "i")) | .state')
```

If Greptile is **not** already running (`PENDING` or `IN_PROGRESS`), request a fresh review:

```bash
if [ "$GREPTILE_STATE" != "PENDING" ] && [ "$GREPTILE_STATE" != "IN_PROGRESS" ]; then
  gh pr comment <PR_NUMBER> --body "@greptile review"
fi
```

Then poll for the Greptile check run to complete:

```bash
HEAD_SHA=$(gh pr view <PR_NUMBER> --json headRefOid -q .headRefOid)

while true; do
  GREPTILE_CHECK=$(gh api "repos/{owner}/{repo}/commits/$HEAD_SHA/check-runs" \
    --jq '.check_runs[] | select(.name | test("greptile"; "i"))' 2>/dev/null)
  
  if [ -z "$GREPTILE_CHECK" ]; then
    echo "Waiting for Greptile check to appear..."
    sleep 5
    continue
  fi
  
  STATUS=$(echo "$GREPTILE_CHECK" | jq -r '.status // "completed"')
  CONCLUSION=$(echo "$GREPTILE_CHECK" | jq -r '.conclusion // "pending"')
  
  if [ "$STATUS" = "completed" ]; then
    if [ "$CONCLUSION" = "success" ]; then
