How to use SVN

Most of the HPSDR software repositories are managed by Subversion, which is a popular collaborative software/firmware development tool for open-source projects. This is a code database repository that is developed with all copies of all code that has been checked in by developers. With a system like this you can go back and check out any previous version of the the software. Wikipedia has an overview of SVN at http://en.wikipedia.org/wiki/Svn_(software).

To access this software you will need to install and use a Subversion (SVN) client. There are several clients listed at the above Wikipedia page. Some of our users have found TortoiseSVN for Windows XP easy to use; it can be downloaded from: http://tortoisesvn.net/. The Tortoise documentation is at http://tortoisesvn.net/support or can be accessed by pressing the F1 key in any Tortoise dialog box.

A free book on subversion is available at: http://svnbook.red-bean.com/

Downloading with TortoiseSVN

This is meant to be a simplified procedure to use the Windows SVN client 'TortoiseSVN'.

You have TortoiseSVN installed and working.

Create a new empty directory, Give it a name appropriate to the item(s) you are downloading.

Go to that empty directory, right click in the empty directory and from the menu choices choose 'SVN Checkout'. Enter the svn address of the item you want in the box titled 'URL of repository:'. A typical entry would be:

svn://184.81.173.3/svn/repos_sdr_hpsdr/trunk/USBBlaster-Binaries

Click OK.

It should download all the data into the directory.....

Our SVN repository

The open HPSDR project maintains a SVN for the the members of the project. The top address of the repository is:

   svn://184.81.173.3/svn/repos_sdr_hpsdr/trunk

Please do not try to check out the entire SVN it is over 2.5 GB. Because of problems the root is no longer browsable. The following directories are under the trunk and are browsable.

Code is not generally erased from a repository. So many of the some of the directories are very active and may change daily other may have not changes in years. Check the dates on the files to determine when tey were lats updated. Your SVN program will help you keep a up to date copy of the code on your computer and you can easily update the directory with a single command.

The repository evolves over time so the organization is not usually for the new viewer but for those that post code. To help people find things here is an index of major folders. Several directories were not included in this list as they are empty.
