阅读此处的其他答案和您的评论，它读起来就像您试图在提交期间修改源文件。这是积极劝阻的；请参阅 http://svnbook。 red-bean.com/en/1.5/svn.reposadmin.create.html#svn.reposadmin.create.hooks 其中有一个红色大警告框，指出：

虽然钩子脚本几乎可以做任何事情，但它有一个维度
哪些钩子脚本作者应该表现出克制：不要修改
使用挂钩脚本提交事务。虽然这可能很诱人
使用钩子脚本自动纠正错误、缺点或

然而，听起来你真正想看的是 svn:keywords。这些允许您在提交时将元数据嵌入到文件中。您唯一不能做的就是嵌入提交日志消息。

实际上，这意味着您需要将包含以下内容的行放入

$Id$

源文件中，然后针对该文件设置属性 svn:keywords 的值为 Id，然后SVN 将在提交时自动扩展它。还有许多其他特殊关键字；请参阅http://svnbook.red-bean。 com/en/1.5/svn.advanced.props.special.keywords.html 了解如何使用这些的所有详细信息。

Reading the other answers here and your comments, it reads like your trying to modify the source file during commit. This is actively discouraged; see http://svnbook.red-bean.com/en/1.5/svn.reposadmin.create.html#svn.reposadmin.create.hooks which has a big red warning box that states:

While hook scripts can do almost anything, there is one dimension in
which hook script authors should show restraint: do not modify a
commit transaction using hook scripts. While it might be tempting to
use hook scripts to automatically correct errors, shortcomings, or
policy violations present in the files being committed, doing so can
cause problems. Subversion keeps client-side caches of certain bits of
repository data, and if you change a commit transaction in this way,
those caches become indetectably stale. This inconsistency can lead to
surprising and unexpected behavior. Instead of modifying the
transaction, you should simply validate the transaction in the
pre-commit hook and reject the commit if it does not meet the desired
requirements. As a bonus, your users will learn the value of careful,
compliance-minded work habits.

However it sounds like what you really want to look at is svn:keywords. These allow you to embed metadata into the file at commit time. The only thing you can't do is embed the commit log message.

Effectively, this means you'd drop a line that contains this:

$Id$

into your source file, then set the property svn:keywords with a value of Id against that file, and SVN will auto-expand it on commit. There's a number of other special keywords as well; see http://svnbook.red-bean.com/en/1.5/svn.advanced.props.special.keywords.html for all the details on how to use these.
