not inside a git repository

Error message

not inside a git repository

What it means

Thrown by `repo_root()` (used by `top_file_path`) when `git rev-parse --show-toplevel` exits non-zero, which happens when the current working directory is not inside a git repository or work tree. The library needs the repo root to locate its top-entries file, so it cannot proceed.

Solutions

1. `cd` into a directory inside a git repository (one containing a valid .git)
2. Run `git rev-parse --show-toplevel` yourself to confirm git sees the repo
3. If .git is broken, restore it (`git init` if appropriate, or re-clone)
4. Check that GIT_DIR/GIT_WORK_TREE env vars are not misdirecting git

Example fix

// before (shell)
~/scratch $ tool commits top
// not inside a git repository
// after (shell)
~/scratch $ cd ~/projects/myrepo
~/projects/myrepo $ tool commits top

// check before invoking any commits subcommand
let out = Command::new("git")
    .args(["rev-parse", "--show-toplevel"])
    .output()?;
if !out.status.success() {
    eprintln!("current directory is not a git repository; cd into a repo first");
    std::process::exit(1);
}

fn inside_git_repo() -> bool {
    Command::new("git")
        .args(["rev-parse", "--is-inside-work-tree"])
        .output()
        .map(|o| o.status.success())
        .unwrap_or(false)
}

match run_top_command() {
    Err(e) if e.to_string() == "not inside a git repository" => {
        eprintln!("Run this from inside a git repository (cwd: {:?})", std::env::current_dir()?);
        std::process::exit(1);
    }
    other => other?,
}

When it happens

Trigger: Invoking any commits/top subcommand from a directory outside a git work tree, inside a bare repository's internals, or in a directory whose .git is corrupt/missing so rev-parse fails.

Common situations: Running the tool in $HOME or a temp dir, running in a submodule-less bare clone, .git directory deleted or corrupted, or GIT_DIR pointing somewhere invalid in the environment.
