Priority System (PR)

This project defines a Priority System that evaluates expressions and manages Lua code within a node pool. It offers a structured way to add and evaluate rules using a variety of data types and Lua-based code.

Features

• Lua Integration: Supports executing Lua scripts within nodes to extend the system’s functionality.
• Priority-based Rule Evaluation: Allows adding rules with priorities for ordered evaluation.
• Efficient Rule Sorting: Implements a quicksort algorithm to sort rules by priority.
• Boolean Expression Handling: Supports a range of boolean and comparison operations (AND, OR, NOT, GT, EQ, etc.).
• Error Handling: Includes error tracking within node pools to detect and manage issues during node operations.
• Streamlined Memory Management: Allocates pools from which it picks the needed objects.

Usage

Initializing Pools:

pr_node_pool *node_pool = pr_node_pool_init(256);        // 256 is the number of nodes
pr_lua_str_pool *lua_pool = pr_lua_str_pool_init(1024);  // 1024 is the number of characters

Adding nodes:

• Adding a value node:

   pr_value value;
   value.i32 = 10;
   uint32_t node_index = pr_add_value_node_to_pool(node_pool, PR_VAL_I32, value);

• Adding a Lua node:

   uint32_t lua_offset = pr_add_lua_code_from_file(lua_pool, "some.rule.lua");
   uint32_t lua_node_index = pr_add_lua_code_node_to_pool(node_pool, lua_pool, lua_offset);

Adding and Evaluating Rules:

pr_rule_pool *rule_pool = pr_rule_pool_init(10);
uint32_t rule_index = pr_add_rule(rule_pool, node_pool, 0, node_index);
bool result = pr_evaluate_rule(rule_pool, rule_index);

Sorting Rules:

pr_sort_rules(rule_pool);

Evaluating All Rules:

bool bool_buffer[10];
pr_evaluate_all_rules(rule_pool, bool_buffer, 10);
