Download the PHP package atomicsmash/nucleus-cli without Composer

Nucleus CLI

A WordPress development toolkit for working with projects that use composer and node to manage assets with a DevOps focus.

Installation

You can install the package globally via composer:

Next you should setup the global Nucleus config (default values):

The config is stored at ~/.config/nucleus/config.yml.

Here is an example with all the current available options:

If you want to view the contents of the config at any time just run:

Usage

Nucleus provides several commands to help set up and manage WordPress projects:

Full Project Setup

Run a complete project setup that executes all setup commands in sequence:

This command will:

1. Ask for confirmation to proceed with the overall setup
2. For each setup command, show a description and ask if you want to run it:
   • Project Configuration: Collect and store project settings (vendor, project name, web root, etc.)
   • Project Core Setup: Copy and configure core project files (composer.json, wp-config.php, etc.)
   • WordPress Setup: Move WordPress to the correct location and organise wp-content directory
   • Plugin Migration: Migrate WordPress plugins to Composer via wpackagist
   • Theme Cleanup: Remove unused themes, keeping only the active theme and its parent
3. Allow you to skip any individual section if you don't need it
4. Provide a summary of completed tasks and next steps

You can also run each command independently if you prefer to set up your project step by step.

Project config file (.nucleus/config.yml)

Per-project settings live in .nucleus/config.yml in the project root. Example:

Project Configuration

Configure in-memory project settings that are shared across onboarding commands:

This command collects and stores the following project information:

• Basic Project Settings: Vendor name, project name, description, license, slug
• WordPress Configuration: Web root path, WordPress install path, PHP version
• Theme Selection: Choose from available themes in current WordPress installation
• Git Configuration: Remote SSH URL, default branch

The configuration is stored in memory and used by subsequent commands, eliminating duplicate prompts.

WordPress Setup

Set up your WordPress installation with proper directory structure:

Note: Requires project configuration to be set up first using nucleus project:config.

The command will:

1. Use stored project configuration (web root, WordPress install path)
2. Find your WordPress installation in common locations
3. Move WordPress to the specified location within the web root
4. Move the wp-content directory to the web root
5. Remove WordPress core files from the target location
6. Provide next steps guidance

WordPress User Management

Manage WordPress users across development, staging, and production environments:

Requirements:

• A wp-cli.yml file in the project root (marks the project as a WordPress installation)
• WP-CLI installed locally for development commands
• A .env file with SSH credentials for staging and production
• wordpress_user_management not set to false in .nucleus/config.yml

Environment selection: Each command prompts you to choose an environment (defaults to development). For staging and production, WP-CLI commands are run remotely over SSH using credentials from your .env file.

Required .env variables for remote environments:

Optional defaults for user:add:

Global config (developer_defaults section via nucleus config:setup):

Project .env fallbacks:

Project Core Setup

Copy and configure core project files from templates:

Note: Requires project configuration to be set up first using nucleus project:config.

The command will:

1. Use stored project configuration (vendor, project name, web root, etc.)
2. Collect environment-specific configuration (database settings, security keys, external services)
3. Copy template files from the nucleus package:
   • .config/wp-configs/* → .config/wp-configs/
   • public/wp-config.php → [web-root]/wp-config.php
   • .editorconfig → .editorconfig
   • .gitignore → .gitignore
   • .valetrc → .valetrc
   • composer.json → composer.json
   • herd.yml → herd.yml
4. Replace placeholders with collected configuration
5. Handle file conflicts with options to overwrite, backup and replace, or skip

Plugin Migration

Migrate your WordPress plugins to Composer via wpackagist:

The command will:

1. Look for the wp-content directory in either:
   • The project root
   • A public directory
2. If not found, prompt you to enter the path or quit
3. Scan all plugins in the plugins directory
4. For each plugin:
   • Extract its version from the main plugin file
   • Check if it exists in the WordPress plugin directory
   • If it exists, add it to composer via wpackagist
   • If not, add it to a list of not found plugins
5. Display any plugins that weren't found in the WordPress directory

Plugins Update

Run the monthly plugin update workflow with optional maintenance emails and deploy steps:

Requirements: Project must have composer.json with johnpbloch/wordpress and at least one of https://wpackagist.org or https://release-belt.atomicsmash.co.uk in repositories. A .nucleus/config.yml file is required.

The command will:

1. Ask if you want to send the monthly maintenance email to your client
2. Check project and (if sending email) global config; prompt for MailerSend API key and sender details if missing
3. Optionally create a maintenance branch from main (e.g. feature/🛠️-Maintenance-YYYY-MM-DD)
4. Optionally send the "starting maintenance" email (Template 1) via MailerSend
5. Check wpackagist and release-belt plugins for updates; show changelog; apply updates (including release-belt flow: plugins.atomicsmash.co.uk + SSH update script)
6. Optionally commit changes to the maintenance branch with a generated commit message
7. Optionally deploy to staging (create release branch, merge maintenance, run npm run deploy)
8. Prompt you to check staging and create a PR (e.g. via Sourcetree or GitLab)
9. Pull main, then optionally deploy to production (npm run deploy:prod)
10. Optionally send the "maintenance complete" email (Template 2) via MailerSend
11. Finish and clear workflow state

Progress is stored in .nucleus/plugin-workflow.yml so you can resume if interrupted. Use --no-resume to start fresh.

Config:

• Project .nucleus/config.yml: onboarded, wordpress_user_management, plugins_update.exclude, maintenance_email.client_name, maintenance_email.client_email, maintenance_email.cc
• Global ~/.config/nucleus/config.yml: mailersend.api_key, mailersend.template_id, and developer_defaults (email_address, first_name, last_name, etc.). Manage with nucleus config:setup / nucleus config:show.

Theme Cleanup

Clean up themes by keeping only the active theme and its parent (if child theme):

The command will:

1. Check for active theme in package.json config (if exists)
2. If not found, prompt you to select the active theme from available themes
3. Detect if the active theme is a parent or child theme by reading style.css
4. If it's a child theme, identify and preserve the parent theme
5. Show a summary of themes to be deleted
6. Confirm deletion with the user
7. Delete all other themes while preserving the active theme and its parent (if applicable)
