📄 Description

Summary

Enhanced Slack Bot plugin to support proper markdown formatting in messages. The bot now correctly converts standard markdown to Slack's mrkdwn format and uses proper Block Kit structure for rich message display. This is especially important in the era of LLMs, as many large models use markdown responses.

Changes Made

  • use https://github.com/fla9ua/markdown_to_mrkdwn to convert standard markdown syntax to Slack mrkdwn format
  • Updated message sending logic to use Block Kit with proper mrkdwn text type
  • Simplified code by removing complex original blocks manipulation
  • Added support for bold, italic, strikethrough, inline code, links, and code blocks formatting

Technical Details

  • Bold: **text** → *text*
  • Italic: *text* → _text_
  • Strikethrough: ~~text~~ → ~text~
  • Links: [text](url) → <url|text>
  • Code: `code` and code blocks remain compatible
  • Uses proper Block Kit structure with "type": "section" and "type": "mrkdwn"

Related Issues or Context

This enhancement addresses the need for proper markdown formatting support in Slack bot responses, ensuring that formatted text from Dify applications displays correctly in Slack channels with proper visual emphasis.
