znc-backlog is a ZNC module that makes it easy to request backlog. Its intended use is for when you have just launched your IRC client and gotten a few lines of backlog sent to you, but want to read more. Instead of having to deal with shelling into the box where you run ZNC and manually sifting through the logs, you can issue a short command in your IRC client to request any amount of the most recent lines of log.

Setup[edit]

You can get this module's source code here. Read the README for information on compiling and installing.

At the moment you must specify a log path manually: See log for information on where ZNC's log module stores logs.

For ZNC versions after 1.6, you would use something like

/msg *backlog LogPath  /path/to/your/logs/$USER/$NETWORK/$WINDOW/*.log

For ZNC versions prior to 1.6, you would use something like

/msg *backlog LogPath /path/to/your/logs/$USER_$NETWORK_$WINDOW_*.log

$USER will be replaced with your ZNC username, $NETWORK with the current network and $WINDOW with the requested channel/window name. The last found asterisk character '*' in the string is assumed to be a date, and the order in which the files are read is determined by a simple alphabetical sort (i.e. date format order must be year-month-day, which is true of output from the log module).

Optionally, you may specify this path as an argument to the module, either in the webadmin textbox, or in the ZNC config file.

Usage[edit]

After the module is loaded and LogPath is set, you can request for logs with:

/msg *backlog <window-name> [num-lines]

e.g.

/msg *backlog #znc 42

[num-lines] is optional and defaults to 150.

Commands[edit]

Help

Prints this text

LogPath <path>

Sets path to log files. Use keywords $USER, $NETWORK, $WINDOW and an asterisk * to stand-in for a year-month-day date.

PrintStatusMsgs <true | false>

Show join/part/rename/etc. messages, in addition to lines of chat.

Tips[edit]

ZNC Alias Module[edit]

You can make requesting backlogs slightly easier in any client with ZNC's alias module.

First, make sure the alias module is loaded:

/msg *status LoadMod alias

Create an alias for using backlog:

/msg *alias create BL
/msg *alias add BL PRIVMSG *backlog :%1% %?2% 50

This creates and then adds to an alias named "BL" that you can use to playback logs. %1% will be replaced by the channel/window name you type when using the alias. %?2% will optionally be the number of lines to play back. If no number of lines is supplied, then the last number is used instead—in this example 50. You can set this number to anything you want.

Now try it out. To play back the default number of lines you set (50 in our example) in the channel #znc:

/bl #znc

To play back exactly 32 lines in the channel #znc:

/bl #znc 32


WeeChat[edit]

In weechat, you can create an alias to make requesting logs for the current window easier:

/alias bl msg *backlog $channel $1

Now you can:

/bl 42

or just:

/bl
