Shortcode module for WordPress.

Installation

Install the module

npm install @wordpress/shortcode --save

This package assumes that your code will run in an ES2015+ environment. If you’re using an environment that has limited or no support for such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.

API

attrs

Parse shortcode attributes.

Shortcodes accept many types of attributes. These can chiefly be divided into named and numeric attributes:

Named attributes are assigned on a key/value basis, while numeric attributes are treated as an array.

Named attributes can be formatted as either name="value", name='value', or name=value. Numeric attributes can be formatted as "value" or just value.

Parameters

• text string: Serialised shortcode attributes.

Returns

• ShortcodeAttrs: Parsed shortcode attributes.

default

Creates a shortcode instance.

To access a raw representation of a shortcode, pass an options object, containing a tag string, a string or object of attrs, a string indicating the type of the shortcode (‘single’, ‘self-closing’, or ‘closed’), and a content string.

Type

• Shortcode

fromMatch

Generate a Shortcode Object from a RegExp match.

Accepts a match object from calling regexp.exec() on a RegExp generated by regexp(). match can also be set to the arguments from a callback passed to regexp.replace().

Parameters

• match Match: Match array.

Returns

• ShortcodeInstance: Shortcode instance.

next

Find the next matching shortcode.

Parameters

• tag string: Shortcode tag.
• text string: Text to search.
• index number: Index to start search from.

Returns

• ShortcodeMatch | undefined: Matched information.

regexp

Generate a RegExp to identify a shortcode.

The base regex is functionally equivalent to the one found in get_shortcode_regex() in wp-includes/shortcodes.php.

Capture groups:

1. An extra [ to allow for escaping shortcodes with double [[]]
2. The shortcode name
3. The shortcode argument list
4. The self closing /
5. The content of a shortcode when it wraps some content.
6. The closing tag.
7. An extra ] to allow for escaping shortcodes with double [[]]

Parameters

• tag string: Shortcode tag.

Returns

• RegExp: Shortcode RegExp.

replace

Replace matching shortcodes in a block of text.

Parameters

• tag string: Shortcode tag.
• text string: Text to search.
• callback ReplaceCallback: Function to process the match and return replacement string.

Returns

• Text with shortcodes replaced.

string

Generate a string from shortcode parameters.

Creates a shortcode instance and returns a string.

Accepts the same options as the shortcode() constructor, containing a tag string, a string or object of attrs, a boolean indicating whether to format the shortcode using a single tag, and a content string.

Parameters

• options ShortcodeOptions: Shortcode options.

Returns

• string: String representation of the shortcode.
