Debugging techniques

Communi recognizes the following environment variables at runtime:

IRC_DEBUG

Value	Description
0	Disable all debug output.
1	Enable debug output.

IRC_DEBUG_LEVEL

Value	Description
0 ("none")	No debug output.
1 ("error")	Output connection errors.
2 ("status")	Output connection status changes.
3 ("write")	Output written (sent) lines.
4 ("read")	Output read (received) lines.

IRC_DEBUG_NAME

The debug output can be filtered so that it only contains lines from specific connections. The filter is case-insensitive and supports wildcards. The filter is matched against the display name of each connection.

Examples:

• IRC_DEBUG_NAME=Freenode matches connections that have a display name "Freenode"
• IRC_DEBUG_NAME=*freenode* matches connections that have a display name "Freenode" or "irc.freenode.net"
