Methods

createOLDelimiterStyleStrategy

This method creates an inline strategy object that can be used to apply a specific style to ordered list delimiters. The strategy object returned by this method contains the following properties:

• style: The style name, which is set to 'OL-DELIMITER'.
• findStyleRanges: A function that takes a block of text and returns an array of ranges where the ordered list delimiter style should be applied. This function uses a regular expression to find ranges that match the pattern for ordered list delimiters (e.g., "1. ", "2. ", etc.).
• styles: An object that defines the styles that should be applied to the ordered list delimiters. In this case, the only style being applied is fontWeight: 'bold'.
