Twig Perversion plugin for Craft CMS

Making twig do things it really shouldn't. Twig is not intended to be a general purpose programming language, and there are some things that really don't belong in the language. This plugin adds a few of those things anyway.

• {% while %}, {% break %}, {% continue %}, and {% return %} tags
• ===, !==, and <=> operators
• is numeric, is string, and is array tests
• array_splice, string, float, int, and bool filters

Requirements

This plugin requires Craft CMS 4.12 or later.

Installation

1. Install with Composer via composer require marionnewlevant/twig-perversion from your project directory
2. Install plugin in the Craft Control Panel under Settings > Plugins

or

1. Install via the Plugin Store

Using Twig Perversion

Tags

• {% while %} loop:

  Note that twig's loop variables (except for revindex, revindex0, last, and length) are available inside of a while loop, as are the {% break %} and {% continue %} tags.

• {% break %} to exit a for loop or while loop:

• {% continue %} to continue to next iteration:

• {% return value %} to return a value from a macro:

• {% return %} to return the empty string from a macro:

  A macro with a {% return %} tag will return whatever the return value is (which can be a complex expression). Any other output generated by the macro will be discarded.

Operators

• === and !==

  Compares two values for equivalence, using php's === and !== operators.

• <=>

  Compares two values using php's <=> (spaceship) operator. Returns -1, 0, or 1 when the first argument is respectively less than, equal to, or greater than the second.

Tests

• Numeric

  Test whether given value is numeric (behaviour like PHP 7 is_numeric). (Note that as of PHP 7, hexadecimal strings are not considered numeric)

• String

  Test whether given value is a string.

• Array

  Test whether given value is an array.

Filters

• array_splice

  Remove a portion of an array and replace it with something else. Uses the PHP array_splice function. Note that unlike the php function, this filter returns the modified array rather than the extracted elements. The original array is unchanged. Since the implementation requires copying the array, this will be less efficient than the raw php function. The array_splice filter is passed an offset, an optional length, and an optional replacement.

• string

  Typecast variable as a string.

• float

  Typecast variable as a float.

• int

  Typecast variable as an integer.

• bool

  Typecast variable as a boolean.
