The bridge connects to `irc.hackclub.com:6667` (no TLS) and forwards messages bidirectionally based on channel mappings:
92
94
95
+
- **NickServ Authentication**: If `NICKSERV_PASSWORD` is configured, the bridge authenticates on connect
96
+
- Waits for NickServ confirmation before joining channels
97
+
- Auto-registers the nick if not registered (requires `NICKSERV_EMAIL`)
98
+
- Prevents "No external channel messages" errors by ensuring proper authentication
93
99
- **IRC → Slack**: Messages from mapped IRC channels appear in their corresponding Slack channels
94
100
- Image URLs are automatically displayed as inline attachments
95
101
- IRC mentions (`@nick` or `nick:`) are converted to Slack mentions for mapped users
96
102
- IRC formatting codes are converted to Slack markdown
97
103
- **Slack → IRC**: Messages from mapped Slack channels are sent to their corresponding IRC channels
98
-
- Slack mentions are converted to `@displayName` format using Cachet
104
+
- Slack mentions are converted to mapped IRC nicks, or the display name from `<@U123|name>` format
99
105
- Slack markdown is converted to IRC formatting codes
100
106
- File attachments are uploaded to Hack Club CDN and URLs are shared
101
107
- **User mappings** allow custom IRC nicknames for specific Slack users and enable proper mentions both ways
