ADR-008: Support openSUSE and Zypper Package Manager

Status

Accepted

Context

Stamp has integration tests running on openSUSE Tumbleweed (test/Dockerfile.opensuse, test/integration/opensuse.sh) but no native package manager adapter for Zypper — openSUSE’s native package manager. Users on openSUSE can only use stamp with cross-platform managers (brew, flatpak).

openSUSE is a major Linux distribution with a large user base, especially in European enterprise and development environments. Zypper is the standard package manager for openSUSE and SUSE Linux Enterprise.

Decision

Implement a Zypper adapter matching the manager.Adapter interface:

Method	Command
ListInstalled	`zypper search --installed-only`
Install	`sudo zypper install -y <pkg>`
Reinstall	`sudo zypper install --force -y <pkg>`
Remove	`sudo zypper remove -y <pkg>`
Search	`zypper search <query>`
Info	`zypper info <pkg>`
Update	`sudo zypper update -y`
Doctor	Not supported
AddRepo/RemoveRepo/ListRepos	Pending investigation — Zypper has repo management via `zypper repos` and `zypper addrepo`

File: internal/manager/zypper.go
NeedsRoot: true (write operations only)
Test file: internal/manager/zypper_test.go

Consequences

openSUSE users get full native package manager support via stamp
Integration tests in opensuse.sh will be extended with Zypper-specific tests covering install, remove, search, and info operations
The existing test/Dockerfile.opensuse already has the necessary dependencies — no infrastructure changes needed
Zypper uses the same sudoCmd helper as APT and DNF for privilege escalation
