GitHubのPull Requestでコミットメッセージの文字数を調べる

git github

GitHubのPull Requestで各コミットメッセージの文字数や変更行数を取得する方法を調べたのでまとめておく。

GraphQL APIで取得できたので、雑にcsv形式にして出力した。

stat-commit-messages.sh

#!/bin/bash

set -eu

OWNER=${1:-rails}
NAME=${2:-rails}
NUMBER=${3:-20000}

echo 'author,subject,body,additions,deletions,changes'
gh api graphql -F owner="$OWNER" -F name="$NAME" -F number=$NUMBER -f query='
  query($name: String!, $owner: String!, $number: Int!) {
    repository(owner: $owner, name: $name) {
      pullRequest(number: $number) {
        commits(first: 100) {
          nodes {
            commit {
              author { name },
              messageHeadline,
              messageBody,
              additions,
              deletions
            }
          }
        }
      }
    }
  }
' --jq '.data.repository.pullRequest.commits.nodes[] | map("\"\(.author.name)\",\(.messageHeadline|length),\(.messageBody|length),\(.additions),\(.deletions),\(.additions + .deletions)") | join("\n")'

実行結果

$ ./stat-commit-messages.sh
author,subject,body,additions,deletions,changes

実際のGitHubのPull Requestは以下の2つで、取得した値もあってそう。
