init
- Usage:
java gitlet.Main init
- Description: Creates a new Gitlet version-control system in the
current directory. This system will automatically start with one
commit: a commit that contains no files and has the commit message
initial commit (just like that, with no punctuation).
It will have a single branch: master, which
initially points to this initial commit, and master will be the
current branch. The timestamp for this initial commit will be
00:00:00 UTC, Thursday, 1 January 1970 in whatever format you
choose for dates (this is
called "The (Unix) Epoch", represented internally by the time 0.)
Since the initial commit in all repositories
created by Gitlet will have exactly the same content,
it follows that all repositories will automatically share
this commit (they will all have the same UID)
and all commits in all repositories will trace back to it.
- Runtime: Should be constant relative to any significant measure.
- Failure cases: If there is already a Gitlet version-control
system in the current directory, it should abort. It should NOT
overwrite the existing system with a new one. Should print the error
message
A Gitlet version-control system already exists in the
current directory.
