Can you do a partial checkout with Subversion

Question

If I had 20 directories under trunk  with lots of files in each and only needed 3 of those directories  would it be possible to do a Subversion checkout with only those 3 directories under trunk

Not in any especially useful way  no   You can check out subtrees  as in Bobby Jack s suggestion   but then you lose the ability to update commit them atomically  to do that  they need to be placed under their common parent  and as soon as you check out the common parent  you ll download everything under that parent   Non-recursive isn t a good option  because you want updates and commits to be recursive

Subversion 1 5 introduces sparse checkouts which may be something you might find useful  From the documentation          sparse directories  or shallow checkouts      allows you to easily check out a working copy   or a portion of a working copy   more shallowly than full recursion  with the freedom to bring in previously ignored files and subdirectories at a later time

Sort of   As Bobby says   svn co file        trunk foo file        trunk bar file        trunk hum   will get the folders  but you will get separate folders from a subversion perspective   You will have to go separate commits and updates on each subfolder   I don t believe you can checkout a partial tree and then work with the partial tree as a single entity

Or do a non-recursive checkout of  trunk  then just do a manual update on the 3 directories you need

Indeed  thanks to the comments to my post here  it looks like sparse directories are the way to go  I believe the following should do it   svn checkout --depth empty http   svnserver trunk proj svn update --set-depth infinity proj foo svn update --set-depth infinity proj bar svn update --set-depth infinity proj baz   Alternatively  --depth immediates instead of empty checks out files and directories in trunk proj without their contents  That way you can see which directories exist in the repository     As mentioned in  zigdon s answer  you can also do a non-recursive checkout  This is an older and less flexible way to achieve a similar effect   svn checkout --non-recursive http   svnserver trunk proj svn update trunk foo svn update trunk bar svn update trunk baz

If you already have the full local copy  you can remove unwanted sub folders by using --set-depth command    svn update --set-depth exclude www   See  http   blogs collab net subversion sparse-directories-now-with-exclusion  The set-depth command support multipile paths   Updating the root local copy will not change the depth of the modified folder   To restore the folder to being recusively checkingout  you could use --set-depth again with infinity param   svn update --set-depth infinity www
