TooPro Code Style Guides

This repository contains comprehensive code style guides used across the TooPro project ecosystem. These guides define the coding standards, conventions, and best practices for multiple programming languages and frameworks.

Overview

The TooPro code style emphasizes pragmatism, compactness, and horizontal space usage over rigid adherence to conventional style guides. Our philosophy prioritizes working, maintainable code that solves real business problems.

Core Principles

1. Practical Over Theoretical - Favor working solutions over architectural purity
2. Minimal Spacing Philosophy - Reduce unnecessary whitespace; compact horizontal code
3. Direct Communication - Clear, descriptive naming; comments explain "why" not "what"
4. Mixed Language Support - Allow native language (Ukrainian/Russian) comments when natural

Style Guides

Note: Style guide files live in plugins/code-style/skills/code-style/references/ — this repo is also a Claude Code skill (see Installing as a Claude Code Skill below).

General Code Style

Cross-language patterns and principles applicable to all TooPro projects:

• Naming conventions
• Code organization
• Error handling patterns
• Documentation standards
• Formatting flexibility

TypeScript Code Style

TypeScript/NestJS specific style for the TpsSrv2 microservices monorepo:

• Compact spacing (no space after if, for, while)
• Single-line conditionals without braces
• No space after colons in type annotations: value:string
• Heavy use of optional chaining: item?.value??defaultValue
• Single quotes for strings

Technology Stack: NestJS, TypeScript, Nx monorepo, RabbitMQ, Directus CMS

PHP Code Style

PHP/Drupal 7 specific style for the TooPro Drupal backend:

• Compact control structures: if($condition) { }
• No space after => in arrays: 'key'=> 'value'
• Old-style array() syntax (PHP 5.3/Drupal 7 compatible)
• Single-line conditionals without braces
• Drupal-specific patterns (hooks, Form API, database queries)

Technology Stack: Drupal 7, PHP 5.3+, MySQL, AMF

ActionScript 3 Code Style

ActionScript3/Adobe Flex specific style for the tps_retail point-of-sale interface:

• No space after control keywords: if(condition) { }
• No space after colons: var x:String
• PureMVC architecture patterns (Proxy, Mediator, Command)
• Underscore prefix for private methods: _loadedProducts()
• Strong typing throughout

Technology Stack: Adobe Flex 4.x, ActionScript 3.0, PureMVC, AMF

Key Style Characteristics

Spacing

• No space after if, for, while, switch keywords
• No space after colons in type annotations
• Minimal spacing around operators when it improves compactness

Braces

• K&R style - opening brace on same line
• Omit braces for single-line conditionals
• Inline statements when appropriate

Type Annotations

// TypeScript
function process(value:string, count:number):boolean { }

// ActionScript3
public function process(value:String, count:Number):Boolean { }

Control Flow

// Single-line conditionals
if(!id) return null;
if(value <= 0) value = 0; else value = Math.round(value * 100) / 100;

// Guards
if(!data) throw new Error('missing data');
if(status !== 'active') return;

Arrays and Objects

// Compact object literals
const point = {x:10, y:20};
const config = {host:'localhost', port:3000, timeout:5000};

// Arrays
const items = ['item1', 'item2', 'item3'];

Usage

These style guides are designed to be used by:

1. Developers - Follow these conventions when writing code for TooPro projects
2. Code Reviewers - Reference when reviewing pull requests
3. AI Code Assistants - Claude Code, GitHub Copilot, and other AI tools should adhere to these styles
4. Linters/Formatters - Configure ESLint, Prettier, and other tools to match these rules

Project Context

Related Repositories

• TpsSrv2 - NestJS microservices monorepo (TypeScript)
• TooPro Drupal - Legacy Drupal 7 backend (PHP)
• tps_retail - Point-of-sale Flash/Flex interface (ActionScript3)

Contributing

When contributing to TooPro projects:

1. Read the appropriate language-specific style guide
2. Review the general code style guide for cross-language patterns
3. Follow existing patterns in the codebase
4. Prioritize clarity and correctness over style perfection
5. When in doubt, check similar code in the same project

Philosophy

The best code is code that works, is understood by the team, and can be maintained over time.
