Constructor Details

#initialize(opts = {}) ⇒ FuzzyPattern

Initializes a fuzzy pattern matcher by processing the pattern string and compiling it into a regular expression.

This method takes the configured pattern string and converts it into a regular expression that can match strings in a fuzzy manner, allowing for partial matches while preserving the order of characters. It handles case sensitivity based on the configuration.

Parameters:

  • opts (Hash) (defaults to: {}) —

    a hash containing the pattern configuration options

Options Hash (opts):

  • :cset (String) —

    the character set to filter pattern characters against

  • :icase (TrueClass, FalseClass) —

    whether the pattern matching should be case sensitive

  • :pattern (String) —

    the pattern string to be used for matching
