GitHub PR Review Operation

GitHub CLI (gh) を使ったPRレビュー操作。

前提条件

  • gh インストール済み
  • gh auth login で認証済み

PR URLのパース

PR URL https://github.com/​OWNER/​REPO/​pull/​NUMBER から以下を抽出して使用:

  • OWNER: リポジトリオーナー
  • REPO: リポジトリ名
  • NUMBER: PR番号

操作一覧

1. PR情報取得

gh pr view NUMBER --repo OWNER/​REPO --json title,body,author,state,baseRefName,headRefName,url

2. 差分取得(行番号付き)

gh pr diff NUMBER --repo OWNER/​REPO | awk '
/^@@/ {
  match($0, /​-([0-9]+)/, old)
  match($0, /\+([0-9]+)/, new)
  old_line = old[1]
  new_line = new[1]
  print $0
  next
}
/^-/ { printf "L%-4d     | %s\n", old_line++, $0; next }
/^\+/ { printf "     R%-4d| %s\n", new_line++, $0; next }
/^ / { printf "L%-4d R%-4d| %s\n", old_line++, new_line++, $0; next }
{ print }
'

  • L数字: LEFT(base)側の行番号 → インラインコメントでside=LEFTに使用
  • R数字: RIGHT(head)側の行番号 → インラインコメントでside=RIGHTに使用

3. コメント取得

Issue Comments(PR全体へのコメント):

gh api repos/​OWNER/​REPO/​issues/​NUMBER/​comments --jq '.[] | {id, user: .user.login, created_at, body}'

Review Comments(コード行へのコメント):

gh api repos/​OWNER/​REPO/​pulls/​NUMBER/​comments --jq '.[] | {id, user: .user.login, path, line, created_at, body, in_reply_to_id}'

4. PRにコメント

gh pr comment NUMBER --repo OWNER/​REPO --body "コメント内容"

5. インラインコメント(コード行指定)

まずhead commit SHAを取得:

gh api repos/​OWNER/​REPO/​pulls/​NUMBER --jq '.head.sha'

単一行コメント:

gh api repos/​OWNER/​REPO/​pulls/​NUMBER/​comments \
  --method POST \
  -f body="コメント内容" \
  -f commit_id="COMMIT_SHA" \
  -f path="src/​example.py" \
  -F line=15 \
  -f side=RIGHT

複数行コメント(10〜15行目):

gh api repos/​OWNER/​REPO/​pulls/​NUMBER/​comments \
  --method POST \
  -f body="コメント内容" \
  -f commit_id="COMMIT_SHA" \
  -f path="src/​example.py" \
  -F line=15 \
  -f side=RIGHT \
  -F start_line=10 \
  -f start_side=RIGHT

注意点:

  • -F (大文字): 数値パラメータ(line, start_line)に使用。-fだと文字列になりエラーになる
  • side: RIGHT(追加行)または LEFT(削除行)

6. コメントへ返信

gh api repos/​OWNER/​REPO/​pulls/​NUMBER/​comments/​COMMENT_ID/​replies \
  --method POST \
  -f body="返信内容"

COMMENT_IDはコメント取得で得たidを使用。
