windmill-infer-args

A TypeScript library for inferring arguments from code snippets in various languages for Windmill workflows.

Installation

``bash
npm install windmill-infer-args
`

Usage

`typescript
import { inferArgs } from 'windmill-infer-args'

// Example schema
const schema = {
properties: {},
required: []
}

async function main() {
// Infer arguments from Python code
const pythonCode =
def main(name: str, age: int = 30):
print(f"Hello, {name}! You are {age} years old.")

const result = await inferArgs('python3', pythonCode, schema)
console.log(schema)
// Output will contain properties for 'name' and 'age' with proper types
// 'name' will be in the required array since it has no default value
}

main()
`
