std_hashmap

std_hashmap is an implementation of the hashmap data type, also known as a dictionary or table.

fetch(std_hashmap);

obj my_hashmap = hashmap();

obj my_hashmap = hashmap_set(my_hashmap, "user", "bob");

obj my_hashmap = hashmap_set(my_hashmap, "age", 23);

obj my_hashmap = hashmap_set(my_hashmap, "birthday", "1/1/25");

obj birthday = hashmap_get(my_hashmap, "birthday");

bark(birthday); # output: 1/1/25

hashmap()

Constructs a new hashmap and returns it.

obj example = hashmap();

bark(example);

hashmap_set(hashmap_obj, key, value)

Sets the hashmap_obj's pair of key & value and returns a new version .

obj example = hashmap();

obj example = hashmap_set(example, "key", "value");

bark(example);

hashmap_get(hashmap_obj, key)

Returns the hashmap_obj's value of key.

obj example = hashmap();

obj example = hashmap_set(example, "key", "value");

bark(hashmap_get(example, "key")); # output: value

hashmap_remove(hashmap_obj, key)

Removes the hashmap_obj's pair of key and returns a new version with the removed pair.

obj example = hashmap();

obj example = hashmap_set(example, "key", "value");

obj removed = hashmap_remove(example, "key"); # empty hashmap because we removed the only key

bark(removed);

hashmap_keys(hashmap_obj)

Returns a list of the hashmap_obj's keys.

obj example = hashmap();

obj example = hashmap_set(example, "key1", "value");

obj example = hashmap_set(example, "key2", "value");

obj keys = hashmap_keys(example);

bark(keys); # output: [key1, key2]

hashmap_values(hashmap_obj)

Returns a list of the hashmap_obj's values.

obj example = hashmap();

obj example = hashmap_set(example, "key1", "value1");

obj example = hashmap_set(example, "key2", "value2");

obj values = hashmap_keys(example);

bark(values); # output: [value1, value2]

bark_hashmap(hashmap_obj)

Pretty print a hashmap.

obj example = hashmap();

obj example = hashmap_set(example, "key1", "value1");

bark_hashmap(example); 

# output: 

# { 

#     key1: value1 

# }
