Functions
- clone (table)
-
Performs a deep/recursive clone on the given table.
Parameters:
- table The table to deep clone.
Returns:
-
The clone of the table.
- comparator (a, b)

A comparator function that can be used for sorting a table with different
value types. It sorts numbers first, after that strings, tables and nil.
Parameters:
- a The first value.
- b The second value.
Returns:
-
true if the first value is less than (should come before) the second.
- equals (a, b)
-
Tests the two given tables for equality.
Parameters:
- a The first table.
- b The second table.
Returns:
-
true if the tables are equal.
- keys (...)
-
Returns a (unique) list with all keys of all tables.
Parameters:
- ... The list of tables.
Returns:
-
A list with all keys.
- merge (...)
-
Merges the given tables into one instance. Note that no cloning is performed
so fields may refer to the same instances.
Parameters:
- ... The tables to merge.
Returns:
-
The merged table.
- to_string (table, one_line, table_ids, indent)
-
Returns the string representation of the given table.
Parameters:
- table The table.
- one_line Optional. If the table should be printed on only one line. Defaults to false.
- table_ids Optional. If the table IDs should be printed. Defaults to true.
- indent Optional. The number of spaces of indentation.
Returns:
-
The string representation of the given table.
