Simplest way to get commit count of a GitHub repo using the API

commitCount.dart

import 'dart:html';

void main() async {
  print(await getCommits(repo: 'river_pod', owner: 'rrousselGit'));
}

Future<String> getCommits({required String repo, required String owner}) async => RegExp(r'(\d+)')
      .allMatches((await HttpRequest.request(
              'https://api.github.com/repos/$owner/$repo/commits?per_page=1'))
          .responseHeaders['link']!)
      .last
      .group(0)!;

commitCount.py

import requests
import re

def commitCount(u, r):
	return re.search('\d+$', requests.get('https://api.github.com/repos/{}/{}/commits?per_page=1'.format(u, r)).links['last']['url']).group()

def latestCommitInfo(u, r):
	""" Get info about the latest commit of a GitHub repo """
	response = requests.get('https://api.github.com/repos/{}/{}/commits?per_page=1'.format(u, r))
	commit = response.json()[0]; commit['number'] = re.search('\d+$', response.links['last']['url']).group()
	return commit

commitCount.sh

curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

### And that's all !
# I saw many fighting with finding first commit SHA or similar fancy thing.
# Here we just rely on the GH API, asking commits at 1 per page and parsing the last page number in the header of the reply (whose body only holds the last commit !)
# So this is robust and bandwidth efficient. :)

# If one want the commit count of a specific SHA, just use :
curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1&sha=:sha" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'
