README

One-command GitHub Pull Request creator/merger in Bash (uses gh). Create a PR from source → target branch, then merge immediately or enable auto-merge.

Requirements

• Linux
• git and gh (GitHub CLI) available in PATH
• gh auth login completed for the machine/CI runner
• Remote named origin pointing to a GitHub repo

1) Install & use with Composer (project-local, dev tool)

Install (dev):

composer require --dev turbocat/power-pr

Add an alias in your project’s composer.json:

{
  "scripts": {
    "power-pr": "vendor/bin/power-pr"
  }
}

Run:

composer power-pr main production
# with options:
composer power-pr main production --strategy squash --labels "release,auto-merge"

2) Install & use with npm (project-local, dev tool)

Install (dev):

npm i -D @turbocat/power-pr

Add an alias in your project’s package.json:

{
  "scripts": {
    "power-pr": "./node_modules/@turbocat/power-pr/bin/power-pr"
  }
}

Run:

npm run power-pr -- main production
# or directly via npx:
npx power-pr main production

3) Use without Composer/npm (vendor-less)

Add the script directly to your repo:

mkdir -p scripts
curl -fsSL https://raw.githubusercontent.com/TurboCatTech/power-pr/main/scripts/power_pr.sh -o scripts/power_pr.sh
chmod +x scripts/power_pr.sh

(optional) Add the tiny wrapper so you can call bin/power-pr:

mkdir -p bin
cat > bin/power-pr <<'SH'
#!/usr/bin/env bash
set -euo pipefail
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
PKG_ROOT="$(cd "$SCRIPT_DIR/.." && pwd)"
exec bash "$PKG_ROOT/scripts/power_pr.sh" "$@"
SH
chmod +x bin/power-pr

Run:

bash scripts/power_pr.sh main production
# or (if you added the wrapper)
bin/power-pr main production

Options, env vars & examples (common to all installs)

Usage

power-pr <source_branch> <target_branch> [options]

Options

• --strategy <merge|squash|rebase> — merge strategy (default: merge)
• --no-auto — don’t enable auto-merge; attempt immediate merge only
• --no-push — skip pushing the source branch before creating the PR
• --allow-dirty — proceed even if there are uncommitted changes
• --title "..." — custom PR title (default: Merge <source> into <target>)
• --body "..." — custom PR body (default: generated summary)
• --labels "a,b,c" — comma-separated labels to apply on creation
• --dry-run — print intended actions without creating/merging a PR

Environment variables

• POWER_PR_STRATEGY — default strategy if --strategy isn’t provided
• POWER_PR_LABELS — default labels if --labels isn’t provided

Exit codes

• 0 success (PR created and merged, or auto-merge enabled)
• ≠0 failure (validation, fetch/push, or gh errors)

Examples (Composer alias shown; identical flags for npm/without)

# Basic deploy PR (main -> production), auto-merge when possible
composer power-pr main production

# Squash merge with labels
composer power-pr main production --strategy squash --labels "release,auto-merge"

# Create PR but don’t enable auto-merge
composer power-pr main production --no-auto

# Dry run (no changes)
composer power-pr main production --dry-run

# Custom title/body
composer power-pr main production \
  --title "Deploy: main → production" \
  --body  "Promotes latest changes to production."

Troubleshooting

• HTTPS prompt error fatal: could not read Username for 'https://github.com': terminal prompts disabled Use SSH remote or configure gh to supply HTTPS credentials:

  git remote set-url origin git@github.com:<owner>/<repo>.git
  # or
  gh auth setup-git

• Uncommitted changes Commit them or use --allow-dirty if you know what you’re doing.

• Branch not found Ensure <target_branch> exists on origin; <source_branch> must exist locally or on remote.
