Hi Back in January I submitted a patch which suggested to teach 'ls-tree' to be able to filter its output based on sparse checkout specifications [1]. My main motivation for doing so was (is) to enable building more tooling on top of sparse checkouts, which is currently hampered a bit by the fact that git doesn't expose the pattern matching rules for the sparse checkouts. I think the main point from that thread was that the 'ls-tree' change was conceptually a larger change that I had initially thought it was. It was suggested that perhaps it would be more straight-forward to initially add a command in the vein of 'git-check-ignore' before teaching all the other commands about sparse checkout specifics, and I think that makes sense. So I am proposing here a new 'check-rules' sub-command to 'sparse-checkout'. This exposes the sparse checkout pattern matching logic while still keeping the pattern specification local to the sparse-checkout command. Since the intention is that this new behavior would not need a work tree as it allows the user to supply a set of rules to verify the paths against, the change that introduces the sub-command is preceded by one that removes the 'NEEDS_WORK_TREE' flag for 'sparse-checkout' and replaces it with calls to 'setup_work_tree()' to keep current behavior. 1: https://public-inbox.org/git/pull.1459.git.1673456518993.gitgitgadget@xxxxxxxxx/ William Sprent (2): builtin/sparse-checkout: remove NEED_WORK_TREE flag builtin/sparse-checkout: add check-rules command Documentation/git-sparse-checkout.txt | 23 +++- builtin/sparse-checkout.c | 132 +++++++++++++++++---- git.c | 2 +- t/t1091-sparse-checkout-builtin.sh | 162 +++++++++++++++++++++++++- 4 files changed, 295 insertions(+), 24 deletions(-) base-commit: d15644fe0226af7ffc874572d968598564a230dd Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-1488%2Fwilliams-unity%2Fsparse-doodle-v1 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-1488/williams-unity/sparse-doodle-v1 Pull-Request: https://github.com/gitgitgadget/git/pull/1488 -- gitgitgadget
