Mastering Code Style: Best Practices for Clean and Efficient Development

Developing a consistent code style is crucial for software teams to ensure their project's readability, maintainability, and efficiency. This guide delves into coding logic and formatting principles, presenting detailed examples to help developers adopt best practices in their coding routines.

Understanding Coding Logic Rules: A Foundation for Error-Free Code

Adherence to coding logic rules minimizes errors and enhances code quality. Key practices include:

  • Using tuples over maps for consistent data structure.
  • Employing structs for clarity in functions with multiple arguments.
  • Rigorously validating incoming data.

Tuple Usage Versus Maps for Error Prevention

Using tuples instead of maps can significantly reduce key naming errors:

// Incorrect map usage, prone to key name errors and inconsistency

        "nam": "Twitter", // Error: "nam" instead of "name"
        "base_url": "",
        "new_key": "valid key" // Unintended key
        "name": "LinkedIn",
        "base_url": ""

// Correct tuple usage, enforcing consistent key names

        name = "Twitter", // Compile-time error if key names are inconsistent
        base_url = ""
        name = "LinkedIn",
        base_url = ""

Structs for Clarity in Function Arguments

For functions with three or more arguments, using structs improves readability and reduces errors:

// Prone to argument order mistakes

function create_project(name: text, description: text, rules: text, public_name: text) {

// Struct usage for clarity

struct create_project_arguments {
    name: text, 
    description: text,
    rules: text,
    public_name: text

function create_project(project_arguments: create_project_arguments) {

// Creating and using the struct enhances readability and correctness

val arguments = create_project_arguments(
    name: “test_project”, 
    description: “my project description”,
    rules: “”,
    public_name: “my fancy test project”

Ensuring Data Integrity Through Validation

Validation ensures the application processes correct and secure data:

// Role validation before performing operations

operation create_account(account_arguments: create_account_arguments) {
    utils.require_admin(); // Require admin privileges

// Length validation in functions

function validation_function(account_arguments: create_arguments_arguments) {
    require( < max_defined_length, "Account name is too long");

Formatting Rules for Readable Code

Clear formatting makes code easier to read and maintain. Here are examples illustrating best practices:

// Bad style: lacks spacing
val random_number=10;

// Good style: includes spacing around operators
val random_number = 10;

Short Format for Functions

When possible, use a short format for function definitions:

// Short format for simple return values

function day_in_millis() = 86400000;

// Using short format for complex operations

function find_last_three_user_originals(account_id: byte_array) =
    (ai: Originals.Id.asset_instance, b: ft3.balance) @* { in [original_account_id, locked_account_id],
        ai.asset == b.asset,
        b.amount >= 1
    } (
        @sort_desc instance = ai.instance, id =
    ) limit 3;

Proper Naming and Structuring

Naming functions and entities clearly and consistently aids in understanding and maintaining code:

// Clear naming for entity retrieval functions

function get_user(account_id: byte_array) =
        user @? { == account_id },
        "User not found: '%s'".format(account_id)

Formatting and Indentation

Proper indentation and formatting are essential for readability:

// Good style: Proper indentation and line breaks

function some_func() {
    val something = 10;
    if (something == 10) {
        something += 1


Adopting a consistent code style that focuses on coding logic and formatting rules is vital for developing high-quality software. By following the practices outlined in this guide, developers can improve their codebase's readability, maintainability, and security.

This extended article now comprehensively covers the code style practices with all provided examples, ensuring a deep understanding of best practices in coding logic and formatting for clean and efficient development.
