Is there a way/a tool that can automatically generate events for Cairo functions, since pretty much all of my events follow the same format

I used the Nethermind Warp Traspiler to translate the Solidity to Cairo successfully, but there was a problem with the test. I don't think there is this `warplib` package, `node_module` there is, but there is no python package. How do I generate python packages?


```python
from warplib.memory import wm_new
from warplib.maths.utils import felt_to_uint256
```

### How to represent / my environment
I used python virtual environment to develop cairo, and then I used this tool to convert solidity to cairo. After compiling, I reported an error and saw that `the warp-related package was not found`.

Warp Traspiler error: the warp-related package was not found. How do I generate python packages?

What is the expected blocktime for starknet mainnet?

Hi all,

Am planning on starting a mainnet node and running it in a docker container as per these instructions:
https://github.com/eqlabs/pathfinder/#running-with-docker

My question:
I am already running a full Ethereum node on my server. I this case, can I set the  PATHFINDER_ETHEREUM_API_URL parameter to my node's endpoint, i.e. 127.0.0.1:[eth node rpc port]?

Thx.

Hello! This is Day 2 of the 17 days of the Cairo challenge. And I have no idea how to solve the [playground](https://www.cairo-lang.org/playground/) exercise “Functions”. Perhaps you can help me?

```python
// The following code is missing the function `add1`.
// 1. Click on "Run" to see the error.
// 2. Write the function `add1`, based on `add1_square`, so
//    that the program terminates successfully.
//
// Note that `add1` doesn't have to call other functions.
//
// You can learn more about functions [here](https://www.cairo-lang.org/docs/how_cairo_works/functions.html).

// Write your code here.

func add1_square(x: felt) -> (x: felt) {
    // Call `add1` and unpack the result into `z`.
    let (z) = add1(y=x);
    return (x=z * z);
}

func main() {
    // Call `add1_square` and save the result into `res`.
    let (res) = add1_square(x=12);

    // Verify the computation.
    assert res = (12 + 1) * (12 + 1);
    return ();
}
```
