Slack Message Blocks Simplified Package

Overview

slack_message_blocks_simplified is a Python package that simplifies the process of creating and sending rich, structured messages to Slack channels using blocks. The package provides various classes to help you build and manage these blocks and interact with Slack's API efficiently.

Installation

pip install slack-message-blocks-simplified

Prerequisites

• Python Version: Ensure you are using Python 3.12 or higher.
• Dependencies:
  • slack_sdk (version 3.31.0)
  • dataclasses (built-in for Python 3.7+)
  • typing (for type hinting)

Usage

Importing the Package

from slack_message_blocks_simplified import  DividerBlock, HeaderBlock, ContextBlock, SectionBlock, ImageBlock, RichTextBlock, SlackBlock, SlackClient

Initialize the Slack client and Slack Block

slack_client = SlackClient(bot_token="xoxb-your-slack-token")
slack_message = SlackBlock(client=slack_client)

Create a message

header = HeaderBlock(title="Welcome to the Channel!")
divider = DividerBlock()
section = SectionBlock()
section.change_value(type="mrkdwn", text="This is a *section* with some _rich text_.")
section.add_image(image_url="https://example.com/image.png", alt_text="Example Image")

Upload file

slack_message.upload_file("C:/path/to/file.extension", "file.extension")

Post the message to a channel

slack_message.add_blocks([header, divider, section])
slack_message.post_message_block(channel_id="C1234567890")

Final code

from slack_message_blocks_simplified import DividerBlock, HeaderBlock, ContextBlock, SectionBlock, ImageBlock, RichTextBlock, SlackBlock, SlackClient

slack_client = SlackClient(bot_token="xoxb-your-slack-token")
slack_message = SlackBlock(client=slack_client)

header = HeaderBlock(title="Welcome to the Channel!")
divider = DividerBlock()
section = SectionBlock()
section.change_value(type="mrkdwn", text="This is a *section* with some _rich text_.")
section.add_image(image_url="https://example.com/image.png", alt_text="Example Image")

slack_message.upload_file("C:/path/to/file.extension", "file.extension")

slack_message.add_blocks([header, divider, section])
slack_message.post_message_block(channel_id="C1234567890")
