check out a single file?

hi

great library, thanks!

I wonder if there is a way to check out a single file? SVN
doesn't allow you
to do this AFAIK, so probably SVNKit doesn't either, but I
thought I'd ask
in case there's something I've missed...

(I'm building a wiki/CMS that uses SVNKit as the backend:
http://gatewiki.sf.net/,
and while users are editing we check out to a
staging area; at present I have to checkout all the files in
the directory
of the file being edited, but would prefer just to check out
one file

thanks again, best,

hamish

I haven't really looked into it, but the next version of
subversion 
should have 'sparse' checkouts; so that helps. If I were you
I'd also 
take a look that the JCR specification, it seems to be much
more 
flexible as far as handling the kind of task you need
(although 
admittedly subversion has been around longer and has more
generic tools).

thanks for that; co with --depth=empty then update on one
file would do the
trick. guess I'll need to wait for 1.5

I did look at the JCR but I like SVN's maturity and
stability, and the ease
of allowing other tools to access the repository, working
copies and so on

tnx

Hello,

While sparse checkout feature is not yet available I'd
suggest you to 
use SVNRepository API to implement editing file.

To get file contents you may obviously use
SVNRepository.getFile(...) 
method. To commit modified version later, you may use the
following snippet:

     String parentDirURL =
"file:///c:/users/alex/sandbox/repos/dir";
     String fileName = "file.txt";
     byte[] newContents = new byte[] {'a', 'b', 'c'};
     InputStream is = new
ByteArrayInputStream(newContents);

     SVNDeltaGenerator generator = new SVNDeltaGenerator();
     SVNURL url = SVNURL.parseURIEncoded(parentDirURL);
     SVNRepository repos =
SVNRepositoryFactory.create(url);

     ISVNEditor commitEditor =
repos.getCommitEditor("message", null);
     try {
         commitEditor.openRoot(-1);
         commitEditor.openFile(fileName, -1);
         commitEditor.applyTextDelta(fileName, null);
         String checksum =
             generator.sendDelta(fileName, is, commitEditor,
true);
         commitEditor.closeFile(fileName, checksum);
         commitEditor.closeDir();
         SVNCommitInfo info = commitEditor.closeEdit();
         System.out.println(info);
         commitEditor = null;
     } finally {
         if (commitEditor != null) {
             commitEditor.abortEdit();
         }
         repos.closeSession();
     }

Neat!  I wonder, is there a way to do this without using the
local
filesystem?
