问题描述
我在大多数项目中都使用Mercurial，并且在部署网站时，我只需要在生产服务器上执行hg clone，然后在其中执行hg pull -u.我想做的是在网站的页脚中添加一小段代码，该代码段显示当前的修订号(十进制和十六进制)以及当前的分支.堆栈溢出和BitBucket都可以满足我的需求.
I use Mercurial for most of my projects and when I deploy a web site, I simply just do an hg clone on the production server and hg pull -u from there. What I'd like to do is add a small snippet to my site's footer which displays the current revision number (both decimal and hex) as well as perhaps the current branch. Stack Overflow and BitBucket both do a variation of what I'm looking for.
我短暂地尝试解析exec('hg summary')的输出，但是在想知道是否还有更好的方法之前，我遇到了一些权限问题.有没有更好的方法，还是exec是我的最佳选择?
I briefly tried parsing the output of exec('hg summary'), but I ran into a couple permissions problems before wondering if there was any better way to do it. Is there a better way, or is exec my best option?
推荐答案
您可以使用更新后挂钩将信息放入文件中.在网站的.hg/hgrc中，您应该输入以下内容:
You could use a post-update hook to put the information in a file. In the site's .hg/hgrc you'd put something like this:
[hooks]
post-update = hg id --rev > VERSION ; hg id --id >> VERSION
然后您可以从php内部访问该文件.您仍然需要确保运行hg pull -u的用户信任hgrc文件，并且VERSION文件具有权限，以便网络服务器可以读取它.
then you can access that file from inside your php. You'll still need to make sure that the user running the hg pull -u trusts the hgrc file and that the VERSION file has permissions such that the webserver can read it.
