clearcase路径是一个标准的 - “@@”和之后的字符串 [英] Is clearcase path is a standard one -- '@@' and string after that

问题描述

  my_source.c @@ \main\10.1_bugfix\这个路径是标准的吗？ 
我在emacs中调用了以下内容，它正在工作。 emacs diff如何理解这个路径。不知何故clearcase通知操作系统如何解释该路径。或者emacs-diff知道这个路径语法？
  $ diff my_source.c @@ \main\10.1_bugfix\ another_branch\0 my_source.c 
  
 
 
解决方案
这是一个 扩展路径 。
 
 
 
是使用动态视图，可以访问元素的分支和版本。
 
 
 
请参阅基本ClearCase路径含义。
 
 
 
在您的情况下，您访问分支的版本0  main\10.1_bugfix\another_branch 。
 
 
 <另请参阅IBM技术说明书关于版本扩展路径为例，  pathnames_ccase  的文档：

你可以将字符添加到相对或完整路径名称的末尾，将其转换为VOB扩展路径名。
 
 指定元素版本的VOB扩展路径名是最常用的;它们称为版本扩展路径名称。 
 
 
 
is the clearcase path syntax is universal one.
my_source.c@@\main\10.1_bugfix\another_branch\0
is this path is standard one? 
I invoked the following in emacs and it is working. how does emacs diff understand this path. somehow clearcase informs operating system how to interpret that path. or emacs-diff know of this path syntax?
$ diff my_source.c@@\main\10.1_bugfix\another_branch\0 my_source.c

解决方案
This is an extended path.

It is working with dynamic views, which give access to the branches and  versions of an element.

See "Base ClearCase path meaning".

In your case, you access the version 0 of the branch main\10.1_bugfix\another_branch.

See also the IBM technote "About the version-extended path" for an example, and pathnames_ccase for the doc:


  
You can add characters to the end of a relative or full path name, turning it into a VOB-extended path name.

  VOB-extended path names that specify versions of elements are the most commonly used; they are called version-extended path names.
