Extensions

The following functions are unique to mooR and not found in original LambdaMOO:

XML/HTML Content Management:

• xml_parse - Parse a string containing XML into a tree of flyweight objects
• to_xml - Convert a tree of flyweight objects into a string containing XML

Import/Export of Objects:

• load_object - Load an object from objdef format with optional conflict detection and resolution options.
• dump_object - Takes an object and returns a list of strings representing the object definition in objdef format.

Flyweights & Symbols (New Types):

• toflyweight - Build a flyweight from a delegate, slots map, and optional contents list
• flyslots - Returns the slots on a given flyweight as a map
• flycontents - Returns the contents list from a flyweight
• flyslotset - Returns a copy of the flyweight with a slot added or updated
• flyslotremove - Returns a copy of the flyweight with the given slot removed, if present
• tosym - Turns the given value into a Symbol

Cryptography:

• age_generate_keypair - Generates a new X25519 keypair for use with age encryption
• age_encrypt - Encrypts a message using age encryption for one or more recipients, outputs as base64
• age_decrypt - Decrypts a base64-encoded age-encrypted message using one or more private keys
• age_passphrase_encrypt - Encrypts a message using age encryption with a passphrase
• age_passphrase_decrypt - Decrypts an age-encrypted message using a passphrase

Administration:

• vm_counters - Performance counters for profiling VM internals
• bf_counters - Performance counters for profiling builtin function performance
• db_counters - Performance counters for profiling DB performance
• function_help - Returns runtime documentation for builtin functions extracted from compiled code

Task Management:

• active_tasks - Return information about running non-suspended/non-queued tasks
• wait_task - Causes the current task to wait for a given task id to complete
• commit - Immediately commits data, suspends, then resumes (semantically same as suspend(0))
• rollback - Immediately rollbacks all mutations to the DB and aborts the current task

• encode_base64 - Encodes a string using Base64 encoding
• decode_base64 - Decodes a Base64-encoded string
• slice - Extracts a portion of a list
• generate_json - Converts a MOO value to a JSON string
• parse_json - Parses a JSON string into a MOO value
• ancestors - Gets a list of all ancestors of an object
• descendants - Gets a list of all descendants of an object
• isa - Checks if an object is a descendant of a specified ancestor
• responds_to - Checks if an object has a specific verb
• pcre_match - Enhanced pattern matching using PCRE regular expressions
• pcre_replace - Text replacement using PCRE regular expressions
