Creating sparse checkout in a new linked git worktree

Creating sparse checkout in a new linked git worktree

[Jessie Hernandez]

Hi All,

I am trying to get a sparse checkout in a linked worktree but cannot get
it working. I have tried the following

* git worktree add /some/new/path/new-branch --no-checkout
* git config core.sparseCheckout true
* <add the directory I would like to checkout out to
$GIT_DIR/info/sparse-checkout>
* cd  /some/new/path/new-branch
* git read-tree -mu sparse-checkout

But I still end up with a fully populated worktree.

Is there something I am missing or doing wrong?

thank you for any response.

The sparse-checkout file is specific to each worktree, which allows
you to control "sparsity" on a worktree by worktree basis. Therefore,
you should create $GIT_DIR/worktrees/<id>/info/sparse-checkout instead
(where <id> is "new-branch" in your example).

Nit. Do

    $EDITOR `git rev-parse --git-path info/sparse-checkout`

if you're already in the right worktree so you don't have to find out
about <id> or the full path.

I wanted to add "git checkout --edit-sparse" for some time. Using it
in multiple worktrees may be a good push for me to eventually do it.

Sure. I will give it a try.

It probably would. Would you be interested in submitting a patch
(mentioning 'git rev-parse --git-path info/sparse-checkout', as
suggested by Duy)?

Right this seems to work indeed.
Thank you.

Would it help if this was added to the documentation of git-read-tree
