2015-07-06worktree: extract basename computation to new functionEric Sunshine
A subsequent patch will also need to compute the basename of the new worktree, so factor out this logic into a new function. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-07-06checkout: retire --to optionEric Sunshine
Now that "git worktree add" has achieved user-facing feature-parity with "git checkout --to", retire the latter. Move the actual linked worktree creation functionality, prepare_linked_checkout() and its helpers, verbatim from checkout.c to worktree.c. This effectively reverts changes to checkout.c by 529fef2 (checkout: support checking out into a new working directory, 2014-11-30) with the exception of merge_working_tree() and switch_branches() which still require specialized knowledge that a the checkout is occurring in a newly-created linked worktree (signaled to them by the private GIT_CHECKOUT_NEW_WORKTREE environment variable).

2015-07-06worktree: add -b/-B optionsEric Sunshine
One of git-worktree's roles is to populate the new worktree, much like git-checkout, and thus, for convenience, ought to support several of the same shortcuts. Toward this goal, add -b/-B options to create a new branch and check it out in the new worktree. (For brevity, only -b is mentioned in the synopsis; -B is omitted.)

2015-07-06worktree: add --detach optionEric Sunshine
One of git-worktree's roles is to populate the new worktree, much like git-checkout, and thus, for convenience, ought to support several of the same shortcuts. Toward this goal, add a --detach option to detach HEAD in the new worktree. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-07-06worktree: add --force optionEric Sunshine
By default, "git worktree add" refuses to create a new worktree when the requested branch is already checked out elsewhere. Add a --force option to override this safeguard. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-07-06worktree: introduce "add" commandEric Sunshine
The plan is to relocate "git checkout --to" functionality to "git worktree add". As a first step, introduce a bare-bones git-worktree "add" command along with documentation. At this stage, "git worktree add" merely invokes "git checkout --to" behind the scenes, but an upcoming patch will move the actual functionality (checkout.c:prepare_linked_checkout() and its helpers) to worktree.c.

2015-06-29worktree: new place for "git prune --worktrees"Nguyễn Thái Ngọc Duy
Commit 23af91d (prune: strategies for linked checkouts - 2014-11-30) adds "--worktrees" to "git prune" without realizing that "git prune" is for object database only. This patch moves the same functionality to a new command "git worktree". Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
