In order to skip this, it's possible for the class to export * its state and be used as actual PHP source code. * * Example: * * // Export with four spaces as the indent, only for the sake of this docblock. * // The default indent is a tab character. * $indent = ' '; * echo $smilies->precomputed_php_source_table( $indent ); * * // Output, to be pasted into a PHP source file: * WP_Token_Map::from_precomputed_table( * array( * "storage_version" => "6.6.0", * "key_length" => 2, * "groups" => "", * "long_words" => array(), * "small_words" => "8O\x00:)\x00:(\x00:?\x00", * "small_mappings" => array( "😯", "🙂", "🙁", "😕" ) * ) * ); * * ## Large vs. small words. * * This class uses a short prefix called the "key" to optimize lookup of its tokens. * This means that some tokens may be shorter than or equal in length to that key. * Those words that are longer than the key are called "large" while those shorter * than or equal to the key length are called "small." * * This separation of large and small words is incidental to the way this class * optimizes lookup, and should be considered an internal implementation detail * of the class. It may still be important to be aware of it, however. * * ## Determining Key Length. * * The choice of the size of the key length should be based on the data being stored in * the token map. It should divide the data as evenly as possible, but should not create * so many groups that a large fraction of the groups only contain a single token. * * For the HTML5 named character references, a key length of 2 was found to provide a * sufficient spread and should be a good default for relatively large sets of tokens. * * However, for some data sets this might be too long. For example, a list of smilies * may be too small for a key length of 2. Perhaps 1 would be more appropriate. It's * best to experiment and determine empirically which values are appropriate. * * ## Generate Pre-Computed Source Code. * * Since the `WP_Token_Map` is designed for relatively static lookups, it can be * advantageous to precompute the values and instantiate a table that has already * sorted and grouped the tokens and built the lookup strings. * * This can be done with `WP_Token_Map::precomputed_php_source_table()`. * * Note that if there is a leading character that all tokens need, such as `&` for * HTML named character references, it can be beneficial to exclude this from the * token map. Instead, find occurrences of the leading character and then use the * token map to see if the following characters complete the token. * * Example: * * $map = WP_Token_Map::from_array( array( 'simple_smile:' => '🙂', 'sob:' => '😭', 'soba:' => '🍜' ) ); * echo $map->precomputed_php_source_table(); * // Output * WP_Token_Map::from_precomputed_table( * array( * "storage_version" => "6.6.0", * "key_length" => 2, * "groups" => "si\x00so\x00", * "long_words" => array( * // simple_smile:[🙂]. * "\x0bmple_smile:\x04🙂", * // soba:[🍜] sob:[😭]. * "\x03ba:\x04🍜\x02b:\x04😭", * ), * "short_words" => "", * "short_mappings" => array() * } * ); * * This precomputed value can be stored directly in source code and will skip the * startup cost of generating the lookup strings. See `$html5_named_character_entities`. * * Note that any updates to the precomputed format should update the storage version * constant. It would also be best to provide an update function to take older known * versions and upgrade them in place when loading into `from_precomputed_table()`. * * ## Future Direction. * * It may be viable to dynamically increase the length limits such that there's no need to impose them. * The limit appears because of the packing structure, which indicates how many bytes each segment of * text in the lookup tables spans. If, however, care were taken to track the longest word length, then * the packing structure could change its representation to allow for that. Each additional byte storing * length, however, increases the memory overhead and lookup runtime. * * An alternative approach could be to borrow the UTF-8 variable-length encoding and store lengths of less * than 127 as a single byte with the high bit unset, storing longer lengths as the combination of * continuation bytes. * * Since it has not been shown during the development of this class that longer strings are required, this * update is deferred until such a need is clear. * * @since 6.6.0 */ class WP_Token_Map { /** * Denotes the version of the code which produces pre-computed source tables. * * This version will be used not only to verify pre-computed data, but also * to upgrade pre-computed data from older versions.
