Adding a file
=============

If you followed well, the next lesson will be straightforward.

We need a new blob::

    >>> ham = Blob.from_string("Another\nmultiline\nfile\n")
    >>> ham.id
    'a3b5eda0b83eb8fb6e5dce91ecafda9e97269c70'

But the same tree::

    >>> tree["ham"] = (0100644, spam.id)

And a new commit::

  >>> c3 = Commit()
  >>> c3.tree = tree.id
  >>> c3.parents = [commit.id]
  >>> c3.author = c3.committer = author
  >>> c3.commit_time = c3.author_time = int(time())
  >>> c3.commit_timezone = c3.author_timezone = tz
  >>> c3.encoding = "UTF-8"
  >>> c3.message = 'Adding "ham"'

Save it all::

    >>> object_store.add_object(spam)
    >>> object_store.add_object(tree)
    >>> object_store.add_object(c3)

Update the head::

    >>> repo.refs['refs/heads/master'] = commit.id

A call to ``git show`` will confirm the addition of "spam".

Remember you can also call ``git checkout -f`` to make it appear.

Well... Adding "spam" was not such a good idea... We'll remove it.
