UniGetUI Version

v2026.2.0

Windows version, edition, and architecture

Windows 10 Pro 22H2 Build 19045 x64

Describe your issue

UniGetUI's Bun manager doesn't detect available updates when Bun is installed via Scoop. In v2026.2.0, installed packages show up but updates don't. In the main branch, both installed packages and updates are broken.

GetGlobalPackagesDirectory() in Bun.cs hardcodes %USERPROFILE%\.bun\install\global\ as the global packages directory. Bun itself resolves this differently — it reads the BUN_INSTALL environment variable first, falling back to ~/.bun.

When Scoop installs Bun, it sets:

• BUN_INSTALL = scoop\persist\bun
• BUN_INSTALL_GLOBAL_DIR = scoop\persist\bun\install\global

UniGetUI ignores both and looks in %USERPROFILE%\.bun\install\global\ — which doesn't exist.

Steps to reproduce the issue

1. Install Bun via Scoop: scoop install bun
2. Install an outdated global package: bun install -g cowsay@1.5.0
3. Open UniGetUI — installed packages appear, but no updates are shown
4. Verify from terminal: bun outdated --global (from any directory) — cowsay 1.5.0 -> 1.6.0 is reported correctly

Relevant information

Paths in play:

Path	Exists (Scoop)	Purpose
%USERPROFILE%\.bun\install\global\	No	What UniGetUI hardcodes
$env:BUN_INSTALL\install\global\	Yes	What Bun actually uses
$env:BUN_INSTALL_GLOBAL_DIR	Yes	Env var pointing to the same place

v2026.2.0 behavior:

Feature	Status	Reason
Installed packages	Works	No guard in GetInstalledPackages_UnSafe() — runs bun pm ls --global directly
Available updates	Broken	HasGlobalPackageManifest guard checks hardcoded path — doesn't exist
Package search	Broken	Uses bun search which doesn't exist (#4859)

Main branch behavior:

Feature	Status	Reason
Installed packages	Broken	HasGlobalPackageManifest guard added — returns empty if missing
Available updates	Broken	HasGlobalPackageManifest guard checks hardcoded path — doesn't exist
Package search	Works	Uses npm registry API (PR #4880)

Workaround:

New-Item -ItemType Junction -Path "$env:USERPROFILE\.bun" -Target "$env:BUN_INSTALL" -Force

Makes the hardcoded path resolve to Scoop's persist directory. Junction must be recreated if Bun is reinstalled via Scoop.

Suggested fix:

GetGlobalPackagesDirectory() should follow Bun's own resolution logic:

internal static string GetGlobalPackagesDirectory(string userProfile)
{
    // 1. Most direct: BUN_INSTALL_GLOBAL_DIR (Scoop sets this)
    string globalDir = Environment.GetEnvironmentVariable("BUN_INSTALL_GLOBAL_DIR");
    if (!string.IsNullOrEmpty(globalDir) && Directory.Exists(globalDir))
        return globalDir;

    // 2. Bun's own fallback: BUN_INSTALL/install/global
    string bunHome = Environment.GetEnvironmentVariable("BUN_INSTALL");
    if (!string.IsNullOrEmpty(bunHome))
        return Path.Combine(bunHome, "install", "global");

    // 3. Official installer default: ~/.bun/install/global
    return Path.Combine(userProfile, ".bun", "install", "global");
}

Falls back to ~/.bun for official installer users, reads BUN_INSTALL for Scoop users.
