8 # A few rules for repo setup:
10 # 1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
13 # 2. .git file is relative to parent directory. .git file is basically
14 # symlink in disguise. The directory where .git file points to will
17 # 3. core.worktree is relative to git_dir.
19 # 4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
20 # equivalent to GIT_WORK_TREE.
22 # 5. GIT_WORK_TREE/core.worktree is only effective if GIT_DIR is set
23 # Uneffective worktree settings should be warned.
25 # 6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
27 # 7. Effective core.worktree conflicts with core.bare
29 # 8. If GIT_DIR is set but neither worktree nor bare setting is given,
30 # original cwd becomes worktree.
32 # 9. If .git discovery is done inside a repo, the repo becomes a bare
33 # repo. .git discovery is performed if GIT_DIR is not set.
35 # 10. If no worktree is available, cwd remains unchanged, prefix is
38 # 11. When user's cwd is outside worktree, cwd remains unchanged,
