Usage

In contrast to the original version (https://github.com/kfei/slack-cleaner) this version is a focusing on pure python package that allows for easy scripting instead of a vast amount of different command line arguments.

basic usage

from slack_cleaner2 import *

s = SlackCleaner('SECRET TOKEN')
# list of users
s.users
# list of all kind of channels
s.conversations

# delete all messages in -bots channels
for msg in s.msgs(filter(match('.*-bots'), s.conversations)):
  # delete messages, its files, and all its replies (thread)
  msg.delete(replies=True, files=True)

# delete all general messages and also iterate over all replies
for msg in s.c.general.msgs(with_replies=True):
  msg.delete()

Token

The slack cleaner needs you to give Slack's API permission to let it run the operations it needs. You grant these by registering it as an app in the workspace you want to use it in.

You can grant these permissions to the app by:

1. going to Your Apps
2. select 'Create New App', fill out an App Name (eg 'Slack Cleaner') and select the Slack workspace you want to use it in
3. select 'OAuth & Permissions' in the sidebar
4. scroll down to User Token Scope and select all scopes you need according to list below
5. select 'Save changes'
6. select 'Install App to Workspace'
7. review the permissions and press 'Authorize'
8. copy the 'OAuth Access Token' shown, and use as the first argument to SlackCleaner

The token should start with xoxp and not like bot tokens with xoxb.

Beyond granting permissions, if you wish to use this library to delete messages or files posted by others, you will need to be an Owner or Admin of the workspace.

User Token Scopes by Use Case

General channel and user detection

• users:read
• channels:read
• groups:read
• im:read
• mpim:read

Deleting messages from public channels

• users:read
• channels:read
• channels:history
• chat:write

Deleting messages from private channels

• users:read
• groups:read
• groups:history
• chat:write

Deleting messages from 1:1 IMs

Note: You can only delete your own messages, not the ones of others. This is due to a restriction in the Slack API and there is nothing one can do about it.

• im:read
• im:history
• users:read
• chat:write

Deleting messages from multi-person IMs

• mpim:read
• mpim:history
• users:read
• chat:write

Deleting files

• files:read
• users:read
• files:write

All User Token scopes

Docker

There is no direct docker file available, however since it is a python module one can easily create one:

FROM python:3.9-alpine

LABEL maintainer="Samuel Gratzl <[email protected]>"

VOLUME "/backup"
WORKDIR /backup

RUN pip --no-cache-dir install slack-cleaner2

CMD ["python", "-"]

An Docker image named slack_cleaner2 with this Dockerfile would be used like

cat myscript.py | docker run -i slack_cleaner2

The myscript.py file is a python script using the slack_cleaner2 module.
