cargo-git

An opinionated helper command to use git with cargo. This does not replace the git command but should be used in conjunction with.

Usage

  1. Starting a new branch.

    Usually you want to fetch first and then create a branch based on master. To do this with Git you will do:

    git checkout master
    git pull --ff-only
    git checkout -b new-branch
    

    With cargo-git, from any branch you can directly do:

    # alias cg="cargo git"
    cg fork new-branch
    

    This command will:

    • make sure there is no uncommitted changes (clean state)
    • fetch (update) master from the remote
    • create a new branch "new-branch" that will be based on origin/master

    Note: the local branch master will not be updated. In fact, you don't even need a local branch master. The exact equivalent with Git would be more something like this:

    git fetch
    # <ensure manually no uncommitted changes are pending>
    git branch -f new-branch origin/master
    git checkout new-branch
    
  2. Pushing the branch

    Usually you want to push with the same name remotely than locally. To do this with Git you will do:

    git push
    # if it fails:
    git push --set-upstream origin new-branch
    

    With cargo-git, only one command is necessary because it will automatically set the upstream if it wasn't set:

    # alias cg="cargo git"
    cg push
    
  3. Updating the branch

    Usually you want to update your local branch with origin/master. To do this with Git you will do:

    git fetch
    git merge origin/master
    # then you will solve all the conflicts of all the commits in one commit,
    # no matter how many commits are conflicting
    

    With cargo-git, you would do:

    # alias cg="cargo git"
    cg update
    # either there is no conflict and you're done
    #
    # or: all the non-conflicting commits will be merged in a single merge
    # commit until the first conflicting commit is reached THEN the first
    # conflicting commit will be merged alone, leaving you in a merge state
    #
    # this will allow you to solve the first conflict separetaly in its own
    # merge commit
    #
    # repeat the command `cg update` until there is nothing more to merge
    

    Note: all the conflicting commits will be merged one-by-one which will allow you to fully understand the reason of the conflict and solve them separately. (A bit like git rebase would do.)

  4. Deleting a branch

    Usually you want to delete the branch locally and remotely when you're done. In Git you would do:

    git branch -d new-branch
    git push origin :new-branch
    

    With cargo-git you can do both at once:

    # alias cg="cargo git"
    cg delete new-branch
    

List of the Available Commands

  • cargo git fork <new-branch> [<from-branch>]

    Create a new branch based on (origin/master by default) and switch to it. Also make an init commit to track the forking branch and commit it came from.

  • cargo git delete <existing-branch>

    Deletes existing branch locally and its upstream.

  • cargo git merge <branch>

    Merge branch to the current branch with a merge commit only (traditional merge). And delete the local and remote branch afterwards.

    This command will fail if there is any conflict. (If the branch given is not up-to-date enough with the current branch.

  • cargo git update

    Update the current branch by merging the parent branch to the current branch.

    This command merge the missing commits from the base branch to the current branch and stops right before it encounters a conflict.

    If the first commit to merge is conflicting, it does a merge alone of this commit, allowing the user to resolve it and commit.

    The command can be (is intended to be) repeated until the current branch has no missing commit.

    It ignores Cargo.lock conflicts by taking the Cargo.lock of the current branch.

  • cargo git update --deps

    Runs cargo update and commit only Cargo.lock alone

  • cargo git push

    Try to push the current branch to its remote branch. If the remote branch does not exist, create one with the same name and set it on the local branch.

  • cargo git add [params]

    Same as git add but doesn't go through Cargo.lock

  • cargo git diff [params]

    Same as git diff but always ignore Cargo.lock

  • cargo git commit [params]

    Commit the files added with the message WIP and add the parent branch in description.

  • cargo git checkout [params]

    Exactly the same as git checkout but always ignore Cargo.lock

    git checkout [params] -- (git diff --name-only | grep -v Cargo.lock)

  • cargo git squash [<other-commit>]

    git reset --soft <other-commit|forking-branch>

    This command allows squashing the current branch by reseting to the parent branch. This command should be followed ultimately by git commit.

    This command will fail if the current branch is not up-to-date with the parent.

  • cargo git check [<revision>]

    Check that HEAD can be merged without conflict

    If the revision argument is not provided, the parent branch is used. If the parent branch is missing, origin/master is used.
