From 94105bd9e2f61b8992a92db9958ccab0a0af1518 Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Mon, 1 Dec 2025 20:07:27 -0800 Subject: [PATCH] feat: add bd migrate-sync command for sync.branch workflow setup (bd-epn) Add a new command that encapsulates all the work needed to migrate a clone to use the sync.branch workflow for multi-clone setups like Gas Town: - Validates current state (not on sync branch, not already configured) - Creates sync branch if it doesn't exist (from remote or locally) - Sets up git worktree for the sync branch - Syncs current beads data to worktree - Commits initial state to sync branch - Sets sync.branch configuration - Pushes sync branch to remote Usage: bd migrate-sync beads-sync # Basic migration bd migrate-sync beads-sync --dry-run # Preview changes bd migrate-sync beads-sync --force # Reconfigure even if set --- cmd/bd/migrate_sync.go | 330 ++++++++++++++++++++++++++++++++++++ cmd/bd/migrate_sync_test.go | 180 ++++++++++++++++++++ 2 files changed, 510 insertions(+) create mode 100644 cmd/bd/migrate_sync.go create mode 100644 cmd/bd/migrate_sync_test.go diff --git a/cmd/bd/migrate_sync.go b/cmd/bd/migrate_sync.go new file mode 100644 index 00000000..80fa0f8a --- /dev/null +++ b/cmd/bd/migrate_sync.go @@ -0,0 +1,330 @@ +package main + +import ( + "context" + "fmt" + "os" + "os/exec" + "path/filepath" + "strings" + + "github.com/spf13/cobra" + "github.com/steveyegge/beads/internal/git" + "github.com/steveyegge/beads/internal/syncbranch" +) + +var migrateSyncCmd = &cobra.Command{ + Use: "migrate-sync ", + Short: "Migrate to sync.branch workflow for multi-clone setups", + Long: `Migrate to using a dedicated sync branch for beads data. + +This command configures the repository to commit .beads changes to a separate +branch (e.g., "beads-sync") instead of the current working branch.
