如何检查存储库是否存在？

发布于 2024-09-07 13:47:12 字数 456 浏览 2 评论 0原文

我想在执行下面的过程之前检查给定路径上是否存在存储库..有什么想法吗？

var exe = Components.classes['@mozilla.org/filelocal;1'].
                     createInstance(Components.interfaces.nsILocalFile);

exe.initWithPath("HG.EXE");

var process = Components.classes["@mozilla.org/process/util;1"].
              createInstance(Components.interfaces.nsIProcess);

Process.init(exe);

args = ["init", "D:\\testRepo\\"];
process.run(blocking, args, args.length);

I want to check whether repository exist on the given path or not before executing the process below..any ideas ?

var exe = Components.classes['@mozilla.org/filelocal;1'].
                     createInstance(Components.interfaces.nsILocalFile);

exe.initWithPath("HG.EXE");

var process = Components.classes["@mozilla.org/process/util;1"].
              createInstance(Components.interfaces.nsIProcess);

Process.init(exe);

args = ["init", "D:\\testRepo\\"];
process.run(blocking, args, args.length);

好吧，您可以使用

hg --cwd the/path/you/want/to/test root

该命令告诉您在 the/path/you/want/to/test 或以上是否有存储库。查看命令的退出代码以查看是否成功。

您还需要将命令打印的根目录与实际目录进行比较 - 可能存在更高级别的存储库，然后 hg root 将报告该情况。

Well, you could use

hg --cwd the/path/you/want/to/test root

That command tells you if there is a repository at the/path/you/want/to/test or above. Look at the exit code of the command to see if it succeeded.

You will also need to compare the root printed by the command with your actual directory -- it could be that there is a repository at some higher level and then hg root will report that.
