How to indent in Drupal

In Drupal, indentation is used to format the code for better readability and maintainability. To indent code in Drupal, you can follow these general guidelines:

1. Indentation in PHP:
– Use spaces for indentation rather than tabs, as per Drupal coding standards.
– Indent each level of code by four spaces.
– Maintain consistent indentation throughout your code.

Example:
“`php
function my_function() {
if ($condition) {
// Indented code block
$variable = ‘value’;
if ($another_condition) {
// Nested indented code block
$another_variable = ‘another value’;
}
}
}
“`

2. Indentation in Twig templates:
– Use two spaces for indentation in Twig templates.
– Indent each level of code by two spaces.
– Maintain consistent indentation throughout the template.

Example:
“`twig
{% if condition %}
{# Indented code block #}
<div class=”my-class”>
{% for item in items %}
{# Nested indented code block #}
<div>{{ item }}</div>
{% endfor %}
</div>
{% endif %}
“`

3. Indentation in CSS:
– Use two spaces for indentation in CSS files.
– Indent each level of code by two spaces.
– Maintain consistent indentation throughout the CSS rules.

Example:
“`css
.my-class {
/* Indented CSS properties */
color: red;
font-size: 16px;

/* Nested indented CSS rules */
.nested-class {
margin-top: 10px;
padding: 5px;
}
}
“`

4. Indentation in JavaScript:
– Use two spaces for indentation in JavaScript files.
– Indent each level of code by two spaces.
– Maintain consistent indentation throughout your JavaScript code.

Example:
“`javascript
function myFunction() {
if (condition) {
// Indented code block
let variable = ‘value’;
if (anotherCondition) {
// Nested indented code block
let anotherVariable = ‘another value’;
}
}
}
“`

Remember that consistent and clear indentation improves code readability and makes it easier to understand and maintain. Following these guidelines will help ensure that your code adheres to Drupal coding standards and best practices.
