## How to use

### Application Specification File

The application file (`app.yml` in the example) is a configuration file that defines the problem-solving logic for your application using Answer Set Programming (ASP). It includes sections for preprocessing, knowledge base (the main logic), and postprocessing.

#### Structure of `app.yml`

The `app.yml` file is structured into three main sections:

1. **Preprocessing**
2. **Knowledge Base**
3. **Postprocessing**

Each section has its own role in preparing the application, encoding the problem-solving logic, and formatting the output.

In the preprocessing section, you can define context information that should be applied before solving the problem and mappings from natural text to facts. The knowledge base section is where you define the main logic of your problem using ASP rules. These rules are used to encode the constraints, relationships, and logic that will drive the decision-making process. The postprocessing section defines the actions to take after the solution is generated by the ASP solver. This section allows you to format and refine the results, as well as provide specific responses.

Example from the file:

```yaml
preprocessing:
- _: You are helping a user with their datalog questions.
- edge(node1,node2): List all the edges from 'node1' to 'node2'.
- reaches(node1,node2): Asks whether 'node2' is reachable from 'node1'.

knowledge_base: |
  reaches(X,Y) :- edge(X,Y).
  reaches(X,Y) :- edge(X,Z), reaches(Z,Y).

postprocessing:
- _: You are helping a user with their datalog questions.
- reaches(node1,node2): Say that 'node2' is reachable from 'node1'. 
```

### Behavior Specification File

The **behavior specification file** (`beh.yml` in the example) defines a global behavior and how the application should process and transform data during both the preprocessing and postprocessing stages. It guides the system in converting natural language input to Answer Set Programming (ASP) code and vice versa, ensuring the logic and output are aligned with the intended behavior.

The file is divided into the following sections:

1. **Preprocessing**
2. **Postprocessing**

Each section serves a different purpose in processing the data from natural language input to ASP code, and from ASP code back to natural language.
The preprocessing section is responsible for converting natural language input into ASP code. It includes instructions that guide the translation process, ensuring that natural language descriptions are accurately and logically reflected in the corresponding ASP predicates. The postprocessing section is responsible for converting ASP facts into natural language output. This section defines how the results, represented as ASP facts, should be translated back into human-readable sentences.

```yaml
preprocessing:
  init: | 
    As an ASP translator, your primary task is to convert natural language descriptions, 
    provided in the format [INPUT]input[/INPUT], into precise ASP code, outputting 
    in the format [OUTPUT]predicate(terms).[/OUTPUT]. Focus on identifying key entities 
    and relationships to create facts (e.g., [INPUT]Alice is happy[/INPUT] becomes [OUTPUT]happy(alice).[/OUTPUT]), 
    [INPUT]Bob owns a car[/INPUT] becomes [OUTPUT]owns(bob, car)[/OUTPUT],
    [INPUT]The sky is blue[/INPUT] becomes [OUTPUT]color(sky, blue)[/OUTPUT], 
    and [INPUT]Cats are mammals[/INPUT] becomes [OUTPUT]mammal(cat)[/OUTPUT]. 
    Ensure that the natural language intent is accurately and logically reflected in the ASP code. 
    Maintain semantic accuracy by ensuring logical consistency and correctly reflecting 
    the natural language intent in your ASP code.
  context: |
    Here is some context that you MUST analyze and always remember.
    {context}
    Remember this context and don't say anything!
  mapping: |
    [INPUT]{input}[/INPUT]
    {instructions}
    [OUTPUT]{atom}[/OUTPUT]

postprocessing:
  init: |
    As an ASP to natural language translator, you will convert ASP facts provided in the format 
    [FACTS]atoms[/FACTS] into clear natural language statements using predefined mapping instructions. 
    For example, [FACTS]happy(alice)[/FACTS] should be translated to "Alice is happy," 
    [FACTS]friend(alice, bob)[/FACTS] to "Alice is friends with Bob," and [FACTS]owns(bob, car)[/FACTS] 
    to "Bob owns a car." Ensure each fact is accurately and clearly represented in natural language, 
    maintaining the integrity of the original information.
  context: |
    Here is some context that you MUST analyze and remember.
    {context}
    Remember this context and don't say anything!
  mapping: |
    [FACTS]{facts}[/FACTS]
    Each fact matching {atom} must be interpreted as follows: {intructions}
  summarize: |
    "Summarize the following responses: {responses}"
```

## Example

Here is a simple example that demonstrates how to use it:

```python
from llmasp import llm, asp

# Specify a model name
model_name = "llama3.1:8b"

# Specify ollama server
server = "http://localhost:11434/v1"

# Create an LLM handler instance
llm_handler = llm.LLMHandler(model_name, server)

# Create a solver instance
solver = asp.Solver()

# Initialize the LLMASP instance with configuration files and handler
llmasp_instance = llm.LLMASP("app.yml", "beh.yml", llm_handler, solver)

# Convert natural language to ASP query
user_input = "There are directed edges from node 1 to node 3, from node 3 to node 4, from node 3 to node 5, from node 4 to node 2, and from node 2 to node 5. Is node 2 reachable from node 1?"
# Indicate whether single or multiple queries should be made to the llm for facts extraction. 
# It's default value is False
single_pass = True
created_facts, asp_input, queries = pipeline.natural_to_asp(user_input, single_pass=single_pass)

# Give the input to the solver
result, interrupted, satisfiable  = solver.solve(asp_input)

# Convert ASP results to natural language
# If you want to give more context to the model, you can pass the history
# history = queries
natural_response = llmasp_instance.asp_to_natural(result, history=[], use_history=False)

print(natural_response)
```
