缘起

Github Trending基本上是我每天都会浏览的网页,上面会及时发布一些GIthub上比较有潜力的项目,或者说每日Star数增量排行榜。

不过由于Github Trending经常会实时更新,即使你访问得再勤,难免还是会错过一些你感兴趣的项目,为此不少人都想出了自己的解决办法,例如
josephyzhou ,他的 github-trending 项目得到了众多人的青睐,我仔细阅读了他的源码 (Go),发现实现也较为简单, 就用Python 重写了一下,发现代码少了好多,详见 我的 github-trending

步骤

主要是建立一个Job,然后分三步:

Job

def job():

    strdate = datetime.datetime.now().strftime('%Y-%m-%d')
    filename = '{date}.md'.format(date=strdate)

    # create markdown file
    createMarkdown(strdate, filename)

    # write markdown
    scrape('python', filename)
    scrape('swift', filename)
    scrape('javascript', filename)
    scrape('go', filename)

    # git add commit push
    git_add_commit_push(strdate, filename)

create markdown

def createMarkdown(date, filename):
    with open(filename, 'w') as f:
        f.write("###" + date + "\n")

write markdown

def scrape(language, filename):

    HEADERS = {
        'User-Agent'        : 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:11.0) Gecko/20100101 Firefox/11.0',
        'Accept'            : 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
        'Accept-Encoding'   : 'gzip,deflate,sdch',
        'Accept-Language'   : 'zh-CN,zh;q=0.8'
    }

    url = 'https://github.com/trending/{language}'.format(language=language)
    r = requests.get(url, headers=HEADERS)
    assert r.status_code == 200

    d = pq(r.content)
    items = d('ol.repo-list li')

    # codecs to solve the problem utf-8 codec like chinese
    with codecs.open(filename, "a", "utf-8") as f:
        f.write('\n####{language}\n'.format(language=language))

        for item in items:
            i = pq(item)
            title = i("h3 a").text()
            owner = i("span.prefix").text()
            description = i("p.col-9").text()
            url = i("h3 a").attr("href")
            url = "https://github.com" + url
            f.write(u"* [{title}]({url}):{description}\n".format(title=title, url=url, description=description))

git operations

def git_add_commit_push(date, filename):
    cmd_git_add = 'git add {filename}'.format(filename=filename)
    cmd_git_commit = 'git commit -m "{date}"'.format(date=date)
    cmd_git_push = 'git push -u origin master'

    os.system(cmd_git_add)
    os.system(cmd_git_commit)
    os.system(cmd_git_push)

部署

代码写完了,然后就可以部署了,当然你可以放在自己的电脑上跑。但是这是个每天的定时任务,所以不能关机比较尴尬。比较好的办法是部署到VPS,具体主机商就不推荐了,反正就这几家,大家随意。部署之前记得先将VPS 的 SSH key 添加到Github 的信任列表,这样这个代码就可以顺利跑起来啦!

  $ git clone https://github.com/bonfy/github-trending.git
  $ cd github-trending
  $ pip install -r requirements.txt
  $ python scraper.py

一般人我不告诉

还有个好处,偷偷告诉你们,这代码是每天定时跑的,所以每天都会Commit 到Github上,想象一下吧,一年之后你的Github下面的Commit 一栏将是多么的美观啊!所以赶快去Star 我的项目,行动起来吧,少年!
