| LIST_VALUE_WRAP_LISTS | If value is a list, wrap it in a list so it can be used with list add/remove operations |
|---|---|
| UNTYPED_LIST_ADD | Add an untyped item to a list, taking care to handle list items by wrapping them in a list to remove the footgun |
| UNTYPED_LIST_REMOVE | Remove an untyped item to a list, taking care to handle list items by wrapping them in a list to remove the footgun |
| LAZYINITLIST | Initialize the lazylist |
| UNSETEMPTY | If the provided list is empty, set it to null |
| ASSOC_UNSETEMPTY | If the provided key -> list is empty, remove it from the list |
| LAZYLISTDUPLICATE | Like LAZYCOPY - copies an input list if the list has entries, If it doesn't the assigned list is nulled |
| LAZYREMOVE | Remove an item from the list, set the list to null if empty |
| LAZYADD | Add an item to the list, if the list is null it will initialize it |
| LAZYDISTINCTADD | Adds an item to the list, initalizing the list if necessary, if the item is not already in the list |
| LAZYOR | Add an item to the list if not already present, if the list is null it will initialize it |
| LAZYFIND | Returns the key of the submitted item in the list |
| LAZYACCESS | returns L[I] if L exists and I is a valid index of L, runtimes if L is not a list |

| LAZYLEN | Returns the lenght of the list |
| LAZYNULL | Sets a list to null |
| LAZYADDASSOC | Adds to the item K the value V, if the list is null it will initialize it |
| LAZYADDASSOCLIST | This is used to add onto lazy assoc list when the value you're adding is a /list/. This one has extra safety over lazyaddassoc because the value could be null (and thus cant be used to += objects) |
| LAZYREMOVEASSOC | Removes the value V from the item K, if the item K is empty will remove it from the list, if the list is empty will set the list to null |
| LAZYACCESSASSOC | Accesses an associative list, returns null if nothing is found |
| QDEL_LAZYLIST | Qdel every item in the list before setting the list to null |
| LAZYCOPY | Use LAZYLISTDUPLICATE instead if you want it to null with no entries |
| LAZYCLEARLIST | Consider LAZYNULL instead |
| SANITIZE_LIST | Returns the list if it's actually a valid list, otherwise will initialize it |

| COMPARE_KEY | Passed into BINARY_INSERT to compare keys |
| COMPARE_VALUE | Passed into BINARY_INSERT to compare values |
| BINARY_INSERT | Binary search sorted insert INPUT: Object to be inserted LIST: List to insert object into TYPECONT: The typepath of the contents of the list COMPARE: The object to compare against, usualy the same as INPUT COMPARISON: The variable on the objects to compare COMPTYPE: How should the values be compared?

Either COMPARE_KEY or COMPARE_VALUE. |
| /proc/english_list | Returns a list in plain english as a string |
| /proc/is_type_in_list | Checks for specific types in a list. |
| /proc/is_path_in_list | Checks for specific paths in a list. |

| /proc/typecache_filter_list_reverse | return a new list with atoms that are not in the typecache list |
| /proc/typecache_filter_multi_list_exclusion | similar to typecache_filter_list and typecache_filter_list_reverse but it supports an inclusion list and and exclusion list |
| /proc/typecacheof | Like typesof() or subtypesof(), but returns a typecache instead of a list. |
| /proc/zebra_typecacheof | Like typesof() or subtypesof(), but returns a typecache instead of a list. This time it also uses the associated values given by the input list for the values of the subtypes. |
| /proc/pick_weight | Picks a random element from a list based on a weighting system. For example, given the following list: A = 6, B = 3, C = 1, D = 0 A would have a 60% chance of being picked, B would have a 30% chance of being picked, C would have a 10% chance of being picked, and D would have a 0% chance of being picked. You should only pass integers in. |
| /proc/expand_weights | Takes a weighted list (see above) and expands it into raw entries This eats more memory, but saves time when actually picking from it |
| /proc/greatest_common_factor | Takes a list of numbers as input, returns the highest value that is cleanly divides them all Note: this implementation is expensive as heck for large numbers, I only use it because most of my usecase Is < 10 ints |
| /proc/pick_n_take | Pick a random element from the list and remove it from the list. |
| /proc/pop | Returns the top(last) element from the list and removes it from the list (typical stack function) |
| /proc/peek | Returns the top (last) element from the list, does not remove it from the list. Stack functionality. |
| /proc/next_list_item | Returns the next item in a list |
| /proc/previous_list_item | Returns the previous item in a list |
| /proc/shuffle | Randomize: Return the list in a random order |
| /proc/shuffle_inplace | same as shuffle, but returns nothing and acts on list in place |
| /proc/unique_list | Return a list with no duplicate entries |
| /proc/unique_list_in_place | same as unique_list, but returns nothing and acts on list in place (also handles associated values properly) |
| /proc/sort_key | for sorting clients or mobs by ckey |
| /proc/sort_record | Specifically for record datums in a list. |
| /proc/sort_list | sort any value in a list |
| /proc/sort_names | uses sort_list() but uses the var's name specifically. This should probably be using mergeAtom() instead |
| /proc/bitfield_to_list | Converts a bitfield to a list of numbers (or words if a wordlist is provided) |

| /proc/count_by_type | return the amount of items of the same type inside a list |
| /proc/move_element | Move a single element from position from_index within a list, to position to_index All elements in the range [1,to_index) before the move will be before the pivot afterwards All elements in the range [to_index, L.len+1) before the move will be after the pivot afterwards In other words, it's as if the range [from_index,to_index) have been rotated using a <<< operation common to other languages. from_index and to_index must be in the range [1,L.len+1] This will preserve associations ~Carnie |
| /proc/move_range | Move elements [from_index,from_index+len) to [to_index-len, to_index) Same as moveElement but for ranges of elements This will preserve associations ~Carnie |
| /proc/swap_range | Move elements from [from_index, from_index+len) to [to_index, to_index+len) Move any elements being overwritten by the move to the now-empty elements, preserving order Note: if the two ranges overlap, only the destination order will be preserved fully, since some elements will be within both ranges ~Carnie |
| /proc/reverse_range | replaces reverseList ~Carnie |
| /proc/get_element_by_var | return first thing in L which has var/varname == value this is typecaste as list/L, but you could actually feed it an atom instead. completely safe to use |
| /proc/deep_copy_list | Copies a list, and all lists inside it recusively Does not copy any other reference type |
| /proc/avoid_assoc_duplicate_keys | takes an input_key, as text, and the list of keys already used, outputting a replacement key in the format of "[input_key] ([number_of_duplicates])" if it finds a duplicate use this for lists of things that might have the same name, like mobs or objects, that you plan on giving to a player as input |
| /proc/flatten_list | Flattens a keyed list into a list of it's contents |
| /proc/make_associative | Make a normal list an associative one |
| DEFAULTPICK | Picks from the list, with some safeties, and returns the "default" arg if it fails |
| /proc/assoc_to_keys | Turns an associative list into a flat list of keys |
| /proc/compare_list | compare two lists, returns TRUE if they are the same |
| /proc/special_list_filter | Returns a list with items filtered from a list that can call callback |
| /proc/recursive_list_resolve | Returns a list with all weakrefs resolved |
| /proc/recursive_list_resolve_element | Helper for recursive_list_resolve() |
| /proc/refify_list | Returns a copy of the list where any element that is a datum or the world is converted into a ref |
| /proc/kvpify_list | Converts a list into a list of assoc lists of the form ("key" = key, "value" = value) so that list keys that are themselves lists can be fully json-encoded |
| /proc/deep_compare_list | Compares 2 lists, returns TRUE if they are the same |
| /proc/weakrefify_list | Returns a copy of the list where any element that is a datum is converted into a weakref |
| /proc/encode_text_and_nulls | Returns a copy of a list where text values (except assoc-keys and string representations of lua-only values) are wrapped in quotes and existing quote marks are escaped, and nulls are replaced with the string "null" |
| /proc/assert_sorted | Runtimes if the passed in list is not sorted |
| /proc/color_string_to_list | Turns a color string such as "#FFFFFF#00FFFF" into a list of ("#FFFFFF", #00FFFF) |
| /proc/color_list_to_string | Turns a list such as ("#FFFFFF", #00FFFF) into a color string of "#FFFFFF#00FFFF" |
