Subject: [PATCH v2 1/2] sparse-checkout: list folders in cone mode
Date: Fri, 27 Dec 2019 18:47:47 +0000 [thread overview]
Message-ID: <d6f4f404866e30e9de89991bb39f2908facb30ae.1577472469.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.500.v2.git.1577472469.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>
When core.sparseCheckoutCone is enabled, the 'git sparse-checkout set'
command takes a list of folders as input, then creates an ordered
list of sparse-checkout patterns such that those folders are
recursively included and all sibling entries along the parent folders
are also included. Listing the patterns is less user-friendly than the
folders themselves.
In cone mode, and as long as the patterns match the expected cone-mode
pattern types, change the output of 'git sparse-checkout list' to only
show the folders that created the patterns.
With this change, the following piped commands would not change the
working directory:
git sparse-checkout list | git sparse-checkout set --stdin
The only time this would not work is if core.sparseCheckoutCone is
true, but the sparse-checkout file contains patterns that do not
match the expected pattern types for cone mode.
