gitdir

Beginnen Sie mit der Worktree API und vergleichen Sie sie mit Repository.Info.WorkingDirectory. Verfolgen Sie, wie .git/worktrees//gitdir den Checkout-Pfad identifiziert, und überprüfen Sie anschließend, dass die neue Eigenschaft tatsächlich das Worktree-Verzeichnis wie C:\repo-core zurückgibt. Damit ist die Aufgabe abgeschlossen, wenn Verbraucher die gitdir-Datei nicht mehr selbst lesen und auflösen müssen.

Problem Description

The Worktree API in LibGit2Sharp does not expose any property to retrieve the actual working directory path associated with a worktree (i.e., the folder where the code is checked out).

Currently, the Worktree object only provides:

• Name → the name of the worktree (e.g., "core")
• GitDirectory → the path .git/worktrees/<name>, which does not correspond to the working directory

Due to this limitation, consumers must manually:

1. Read the content of .git/worktrees/<name>/gitdir
2. Use Directory.GetParent() to resolve the real worktree folder path

This approach is both fragile and undocumented.

Expected Behavior

Expose a property like Worktree.WorkingDirectory (similar to Repository.Info.WorkingDirectory) that returns the actual working directory path of the worktree (e.g., C:\repo-core).

Example Workaround

var worktreePaths = new List<string>();
var gitDir = Path.Combine(repoPath, ".git", "worktrees");

foreach (var folder in Directory.GetDirectories(gitDir))
{
    var gitdirFile = Path.Combine(folder, "gitdir");
    if (File.Exists(gitdirFile))
    {
        var gitdirPath = File.ReadAllText(gitdirFile).Trim();
        var worktreePath = Directory.GetParent(gitdirPath)?.FullName;
        if (!string.IsNullOrEmpty(worktreePath))
            worktreePaths.Add(worktreePath);
    }
}

This code reads the .git/worktrees/<name>/gitdir file and manually resolves the worktree’s root folder. A native API would make this more reliable and developer-friendly.
