So far I have figured out how to get the treeWalk for the path filter as
shown below.
Now I am lost as to how to get the blob associated with the treeWalk.
TIA for your help.
/**
* Gets the content of specified file in git Repo.
*
* @parameter relativePath the relative path in jitRepo for desired
file to get
* @parameter versionName the versionName for the desired file. It
will be unmarshalled from String to ObjectId.
* @return the content of the desired file version packaged as a
DataHandler.
*/
public DataHandler get(String relativePath, String versionName)
throws RepositoryException {
ObjectId retrieveStart = repository.resolve(versionName);
RevWalk revWalk = new RevWalk(repository);
RevCommit entry = revWalk.parseCommit(retrieveStart);
RevTree revTree = entry.getTree();
TreeWalk treeWalk = TreeWalk.forPath(repository,
relativePath, revTree);
//Not sure how to get the blob next
}

For my immediate needs, I need to implement a GitRepository class with
two methods using gjit as shown below. I would appreciate any guidance
and pseudo-code examples on how to implement these methods. Please
keep in mind that I am just getting to know git itself and gjit was
key to my considering git over Mercurial and other distributed VCSs.
public class GitRepositoryManager {
Repository gitRepo;
...
/**
* Gets the content of specified file in git Repo.
*
* @parameter relativePath the relative path in jitRepo for
desired file to get
* @parameter versionName the versionName for the desired file. It
will be unmarshalled from String to ObjectId.
* @return the content of the desired file version packaged as a
DataHandler.
*/
public DataHandler get(String relativePath, String versionName)
throws RepositoryException {
DataHandler dh = null;
...
return dh;
}
/**
* Creates a new version of specified version of file in git Repo.
*
* @parameter relativePath the relative path in jitRepo for
desired file to get
* @parameter versionName the versionName for the desired file. It
will be unmarshalled from String to ObjectId.
* @parameter content the content of the new version for specified
file packaged as a DataHandler.
*/
public void update(String relativePath, String versionName,
DataHandler content) throws RepositoryException {
...
}
}

Now I am wondering where to begin to learn how to do the equivalent
of the
following commands via the gjit Java API:
* git add /file/
* git rm /file/
* git mv /file
* Whatever is the git way to get a specific version of a file
JGit currently has two APIs for working with the index, which will
allow you to add, remove and move data around in the tree. In nbgit I
ended up using GitIndex, which I found easier to figure out. As I
understand it, in the long run you want to use the DirCache API, but
it is still a work in progress.
I am happy to use GitIndex now and switch to DirCache API later when
it is ready.
Can I please get some pseudo-code fragments on how to do the use
cases I identified above?
The javadoc is still not obvious to me.
I am hoping that there aremore docs, samples, tutorials etc.
somewhere that
I am missing. Thanks for any help you can provide. Some pointers or
code
fragments would be terrific.
I started working on a tutorial for JGit, but didn't get very far so
it mostly consists of stub pages.
- http://code.google.com/docreader/#p=egit&s=egit&t=JGitTutorial
I have been working on moving the tutorial to maven project before
starting to write the more code heavy topics. This would make it
possible to include code snippets in the tutorial, while also allowing
to compile and test the examples.
The wiki is an awesome resource even in its current state. Thank you.
I would be glad to help contribute improvements to wiki if you give me
write privilege. What I could do is take the help I get from the list
and
then update wiki carefully as appropriate if you want me to help.
Thanks again to all of you for helping get me bootstrapped with gjit
and git.
