Enum TemplateDir 

pub enum TemplateDir {
    Unresolvable,
    NoGit,
    IsCheckout,
    InsideCheckout,
    Safe,
}

What may be done with a candidate template directory.

~/.config/git/git-templates is commonly a SYMLINK to a checkout of this repository, in which case “installing” there means deleting and overwriting TRACKED files.

Comparing the path against the source tree is NOT enough, and that is the mistake that caused both incidents: run the install from a git worktree and the two resolve to different paths — a different checkout of the same repo — so a path comparison says “not the source” and clobbers the main checkout. Asking git is the reliable test whatever route the symlink took.

Variants

Unresolvable

The path does not exist and could not be created.

NoGit

No git to ask. Refuse rather than guess.

IsCheckout

It holds tracked files: it IS a checkout. Nothing to install — git init already reads its templates from there, and the shims keep their placeholder and resolve the binary at run time.

InsideCheckout

Inside a checkout but tracking nothing here. Still not ours to empty.

Safe

An ordinary directory. Safe to populate.
