获取WinCvs中标记文件的修订号 [英] Get revision number of a tagged file in WinCvs

问题描述

这似乎应该很简单，但是我找不到任何可行的解决方案...

This seems like it should be so simple, but I can't find any solution that appears to work...

我需要一个CVS命令，

I need a CVS command that given the name of a tag that you have applied to a file, it will give you the revision number.

CVS树结构：

(filename)
    |
    +--> 1.1-----(branch)
          |         |
          |      1.1.1.1---(tag1)
          |         |
          |      1.1.1.2---(tag2)
          |         |
          |      1.1.1.3---(tag3)
          |         |
          |         :
         1.2
          |
          |
          :

例如：使用CVS命令，给定标签名称 tag2，我怎样才能得到CVS给我修订号 1.1.1.2？

---

我能找到的最接近的东西是使用带有 -Q 标志的 log 命令，但这仍然为我提供了比我所需更多的信息。

For example: Using a CVS command, given the tag name "tag2", how can I get CVS to give me the revision number "1.1.1.2"?

---

The closest thing I can find is using the log command with the -Q flag, but that still gives me much more information than I need.

例如： cvs -Q log -h文件名

将标记名传递给 log 命令似乎无效。

Passing the tagname to the log command seems to have no effect.

CVS版本信息：

我当前的解决方案是使用perl脚本来解析 log 命令，但必须有一种更简单的方法...

My current solution is to use a perl script to parse the output from the log command but there has to be a simpler way...

推荐答案

传递标记名（带有-r选项）到log命令确实有效果，只是不是特别有用

Passing a tag name (with a -r option) to the log command does have an effect, just not a particularly useful one and it's effect is hidden by "-h".

通常是获得 VERSION 文件（通常的用例）是在其中包含关键字；即：

Usually the easiest way to get a revision number for your VERSION file (the normal use-case for this) is to include a keyword in it; ie:

# Thu 21 May 08:40:59 BST 2015
THISREV="$Revision$"

注意：要获取版本号 VERSION 的存储库版本号必须在每次每次提交存储库时提交文件。

Note: to get a repository version number this VERSION file must be committed every time you make a commit to the repo.

如果您需要对特定文件进行修订，则基本上从日志的符号名称部分退回脚本。因此，对于 r-1-0-0 ，您可以执行以下操作：

If you need a revision for a specific file then you're basically falling back on scripting from the "symbolic names" part of the log. So for r-1-0-0 you do this:

cvs -Q log -h VERSION | awk '/^\tr-1-0-0:/ {print $NF;}'

没有与 git describe 命令直接等效的东西。

There's no direct equivalent of the git describe command.
