scratchattach 1.0.8

An Scratch API Wrapper for scratch.mit.edu

Scratch API wrapper with support for almost all site features

This library can set cloud variables, follow Scratchers, post comments and do so much more! It has special features that make it easy to transmit data through cloud variables.

Some functions require logging in to Scratch. You also need to have the coding language Python installed on your device. Download Python here if you don't have it: https://www.python.org/downloads/

The project is maintained by TimMcCool: https://scratch.mit.edu/users/TimMcCool/

Installation

Run the following command in your command prompt / shell:

pip install -U scratchattach

OR

Add this to your Python code:

import os

os.system("pip install -U scratchattach")

Logging in scratch3.Session

Logging in with username / password:

import scratchattach as scratch3

session = scratch3.login("username", "password")

login() returns a Session object that saves your login

Logging in with a sessionId: You can get your session id from your browser's cookies. More information

import scratchattach as scratch3

session = scratch3.Session("sessionId", username="username")

Attributes:

session.session_id #Returns the associated session id
session.xtoken
session.email #Returns the email address associated with the account
session.new_scratcher #Returns True if the associated account is a New Scratcher
session.mute_status
session.banned #Returns True if the associated account is banned

Cloud variables scratch3.CloudConnection

Make sure you're using the latest scratchattach version. Update scratchattach with pip install scratchattach --upgrade

Connect to the Scratch cloud:

With a Session object:

conn = session.connect_cloud("project_id")

Directly with a sessionId (cookie connect):

conn = scratch3.CloudConnection(project_id = "project_id", username="username", session_id="sessionId")

Connect to the TurboWarp cloud:

Does not require a session.

conn = scratch3.TwCloudConnection(project_id = "project_id", username="username")  
# Optional argument: cloud_host="wss://clouddata.turbowarp.org"
# To connect to forkphorus's cloud server, use cloud_host="wss://stratus.turbowarp.org"

Set a cloud var:

New Scratchers can set Scratch cloud variables too.

conn.set_var("variable", "value") #the variable name is specified without the cloud emoji

Get a Scratch cloud var from the clouddata logs:

Does not require a connection / session.

value = scratch3.get_var("project_id", "variable")
variables = scratch3.get_cloud("project_id") #Returns a dict with all cloud var values
logs = scratch3.get_cloud_logs("project_id") #Returns the cloud logs as list

Get a Scratch / TurboWarp cloud var from the websocket: (new in v0.8.0)

Requires a connection to Scratch or TurboWarp's cloud (a CloudConnection / TwCloudConnection object).

value = conn.get_var("variable")

Close the cloud connection:

conn.disconnect()

Encoding / Decoding scratch3.Encoding

Scratchattach has a built in encoder. Scratch sprite to decode texts encoded with scratchattach: https://scratch3-assets.1tim.repl.co/Encoder.sprite3

from scratchattach import Encoding

Encoding.encode("input") #will return the encoded text
Encoding.decode("encoded") #will decode an encoded text

Cloud events scratch3.CloudEvents

Cloud events allow reacting to cloud events in real time. If a Scratcher sets / creates / deletes a cloud var on the given project, an event will be called.

They do not require a session.

How to use with Scratch:

import scratchattach as scratch3

events = scratch3.CloudEvents("project_id")

@events.event
def on_set(event): #Called when a cloud var is set
    print(f"{event.user} set the variable {event.var} to the valuee {event.value} at {event.timestamp}")

@events.event
def on_del(event):
    print(f"{event.user} deleted variable {event.var}")

@events.event
def on_create(event):
    print(f"{event.user} created variable {event.var}")

@events.event #Called when the event listener is ready
def on_ready():
   print("Event listener ready!")

events.start()

How to use with TurboWarp: (new in v0.4.7)

import scratchattach as scratch3

events = scratch3.TwCloudEvents("project_id")

...

Functions:

events.start(thread=True)
events.pause()
events.resume()
events.stop()

Cloud Requests scratch3.CloudRequests

Cloud Requests Framework (inspired by discord.py) that allows Scratch projects and Python to interact

This makes it possible to access data like message counts, user stats and more from Scratch projects! Uses cloud variables to transmit data.

Cloud Requests are documented on this page:

https://github.com/TimMcCool/scratchattach/blob/main/CLOUD_REQUESTS.md

If you want to access external information in Scratch projects or store data on an external database, scratchattach's Cloud Requests are ideal for your project:

• Similar to cloud events, but send back data to the project
• Automatically encode / decode sent data
• Tons of extra features
