Subversion expansion tag

by **spr** » 06 Aug 2013, 01:22

There is a very useful expansion tag I have noticed in the code -

Code: Select all: * @version $Id: CardFactoryUtil.java 22806 2013-08-05 18:02:21Z Sloth $

I added it to some new code I recently committed as "@version $Id$" but it does not seem to have expanded. If someone can confirm what the correct syntax is that would be awesome!

Cheers,
Steve

I believe it's $Id:

Nope. Tried "$Id:" and "$Id:$". Remains resolutely unexpanded.

It only expands when you commit, and you need to make sure the files have their svn:keywords set appropriately for that file.

You do need the ending $ as well.

Thanks for the link. I just assumed it would be some server setting but it looks like I will need to run the following for each file I want substitution to take place in. I will give it a go next time I commit.

Code: Select all: svn propset svn:keywords "Id" <filename>.java

EDIT: and for this to work <filename>.java must have been checked into subversion at least once. It will fail if the file does not yet exist in subversion.
EDIT: and it works! Finally!

EDIT: just to confirm the tag is "$Id:$".

Cheers,
Steve
