prstack sync

Syncs your current stack with the remote repository.

Usage

prstack sync

What It Does

The sync command performs the following operations in order:

1. Fetches latest changes from the remote repository
2. Updates local trunk to match the remote trunk branch
3. Discovers current stack by tracing from your current position back to trunk
4. Optionally rebases the stack on the updated trunk (only if trunk changed)
5. Pushes tracked branches to the remote
6. Offers to create missing PRs for branches without pull requests

Dynamic Stack Discovery

The key feature of prstack sync is its dynamic stack discovery. It doesn't require you to pre-define your stack structure. Instead, it automatically discovers your stack by tracing from wherever you are back to the trunk branch.

Example

# You're on feature-b which is based on feature-a
# feature-a is based on main

prstack sync

# Output:
# Fetching from remote...
# Updating trunk (main)...
# Discovered stack: feature-b → feature-a → main
# Trunk has new commits, rebase? (y/n)
# Pushing branches...
# Missing PRs detected:
#   - feature-a → main
#   - feature-b → feature-a
# Create missing PRs? (y/n)

When to Use

Use prstack sync when you want to:

• Update your stack with the latest changes from remote
• Ensure your stack is in sync before creating PRs
• Rebase your entire stack on the latest trunk
• Quickly identify and create missing PRs
