# ILAng with Python

## ILAng Python interface

{% hint style="info" %}
 The Python API will be deprecated and thus no future official support.
{% endhint %}

## Synthesis engine

As part of the ILAng platform, [ItSy](https://github.com/PrincetonUniversity/ItSy) (ILA synthesis engine) provides a Python API for writing synthesis templates, interfacing simulator, and scripting the synthesis process. To build the Python module:

```bash
cd itsy/root/dir
bjam -j$(nproc)
```

The Python module `ila.so` will be available in the `build` directory. Run or add the following command in your `.bashrc` file to set the path: 

```bash
export PYTHONPATH=$(pwd)/build:$PYTHONPATH
```

Once the path is set properly, you can then access the synthesis Python module:

```python
import ila
abs = ila.Abstraction("test")
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bo-yuan-huang.gitbook.io/ilang/start/python.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
