master  #the common features are here like Core, DAL,...

Answer 1

In addition of git worktree add --checkout, Git 2.16 (Q1 2018) will propose another alternative:

The way "git worktree add" determines what branch to create from where and checkout in the new worktree has been updated a bit.

See commit e92445a, commit 71d6682 (29 Nov 2017), and commit 4e85333, commit e284e89, commit c4738ae, commit 7c85a87 (26 Nov 2017) by Thomas Gummerer (tgummerer).

add worktree.guessRemote config option

Some users might want to have the --guess-remote option introduced in the previous commit on by default, so they don't have to type it out every time they create a new worktree.

Add a config option worktree.guessRemote that allows users to configure the default behaviour for themselves.

The documentation for git config now reads:

worktree.guessRemote::

With add, if no branch argument, and neither of -b nor -B nor --detach are given, the command defaults to creating a new branch from HEAD.
If worktree.guessRemote is set to true, worktree add tries to find a remote-tracking branch whose name uniquely matches the new branch name.

• If such a branch exists, it is checked out and set as "upstream" for the new branch.
• If no such match can be found, it falls back to creating a new branch from the current HEAD.

Actually, Git 2.21 (Q1 2019) clarifies the documentation for this option, which jumped right in with "With add", without explaining that add is a sub-command of "git worktree".

See commit b4583d5 (23 Dec 2018) by Eric Sunshine (sunshineco).
^{(Merged by Eric Sunshine -- sunshineco -- in commit b4583d5, 28 Dec 2018)}

The documentation now reads:

worktree.guessRemote:

If no branch is specified and neither -b nor -B nor --detach is used, then git worktree add defaults to creating a new branch from HEAD.
