# LLM Functions
This project allows you to enhance large language models (LLMs) with custom functions written in bash/js/python. Imagine your LLM being able to execute system commands, access web APIs, or perform other complex tasks – all triggered by simple, natural language prompts.
## Prerequisites
Make sure you have the following tools installed:
- [argc](https://github.com/sigoden/argc): A bash command-line framewrok and command runner
- [jq](https://github.com/jqlang/jq): A JSON processor
## Getting Started with AIChat
**1. Clone the repository:**
```sh
git clone https://github.com/sigoden/llm-functions
```
**2. Build function declarations file and bin dir:**
First, create a `./functions.txt` file with each function name on a new line.
Then, run `argc build` to build function declarations file `./functions.json` and bin dir `./bin/`.
**3. Configure your AIChat:**
Symlink this repo directory to aichat **functions_dir**:
```sh
ln -s "$(pwd)" "$(aichat --info | grep functions_dir | awk '{print $2}')"
# OR
argc install
```
Don't forget to add the following config to your AIChat `config.yaml` file:
```yaml
function_calling: true
```
AIChat will automatically load `functions.json` and execute functions located in the `./bin` directory based on your prompts.
**4. Start using your functions:**
Now you can interact with your LLM using natural language prompts that trigger your defined functions.
## Function Types
### Retrieve Type
The function returns JSON data to LLM for further processing.
AIChat does not ask permission to run the function or print the output.
### Execute Type
The function does not have to return JSON data.
The function can perform dangerous tasks like creating/deleting files, changing network adapter, and setting a scheduled task...
AIChat will ask permission before running the function.
**AIChat categorizes functions starting with `may_` as `execute type` and all others as `retrieve type`.**
## Writing Your Own Functions
You can write functions in bash/javascript/python.
`llm-functions` will automatic generate function declarations from comments. Refer to `demo_tool.{sh,js,py}` for examples of how to use comments for autogeneration of declarations.
### Bash
Create a new bashscript in the [./tools/](./tools/) directory (.e.g. `may_execute_command.sh`).
```sh
#!/usr/bin/env bash
set -e
# @describe Runs a shell command.
# @option --command! The command to execute.
main() {
eval "$argc_command"
}
eval "$(argc --argc-eval "$0" "$@")"
```
### Javascript
Create a new javascript in the [./tools/](./tools/) directory (.e.g. `may_execute_js_code.js`).
```js
/**
* Runs the javascript code in node.js.
* @typedef {Object} Args
* @property {string} code - Javascript code to execute, such as `console.log("hello world")`
* @param {Args} args
*/
exports.main = function main({ code }) {
eval(code);
}
```
### Python
Create a new python script in the [./tools/](./tools/) directory (e.g., `may_execute_py_code.py`).
```py
def main(code: str):
"""Runs the python code.
Args:
code: Python code to execute, such as `print("hello world")`
"""
exec(code)
```
