Irssi smart filter to selectively hide JOIN/QUIT in busy channels

irssi-smartfilter

This script filters JOIN, PART, QUIT and NICK event messages to active users only.

When the script is running, a user's events will only be displayed when they have been active recently. If the user is not active in the channel, their events will be ignored.

This script limits noise from large channels, while preventing you from talking to a conversation partner who has left (which can happen if you just ignore all events).

By default, a user is considered active if they have said something in the last 20 minutes. If they leave the channel, change nick etc., they are kept active, so you will not miss re-joins or subsequent nick changes.

Usage

• Download smartfilter.pl to your .irssi/scripts directory
• To run once: /run smartfilter
• To run automatically, create a symlink to smartfilter.pl in your .irssi/scripts/autorun directory

Optional configuration

• You can specify a space-separated list of channels for which the filtering will be disabled: /set smartfilter_ignored_chans #channel1 #channel2
• You can change the recent activity time (in seconds): /set smartfilter_delay 1200
• Old nicks are removed from memory periodically. You can change how often the garbage collection runs by picking after how many smartfilter-delays it runs: /set smartfilter_garbage_multiplier 4

irssi-smartfilter's Issues

Filter based on channel population

The more people in a channel, the more distracting it is to see all the joins and parts, but for smaller channels it's not such a big deal.

It would be nice to be able to set a population threshold (say 100), and automatically filter channels with more than that many users.

Trim the active list to prevent memory leaks

Any entries older than smartfilter_delay can be safely removed.

Avoid filtering autolog

The script is great at filtering out unnecessary join/quit messages, but they don't show up in the logs. This makes it difficult to tell when someone quit. Is there a way to ensure the filtered messages make it into the log? I'm using autolog for that.

Themes may break nickchange/quit detection

As of 2370378, smartfilter is broken with themes which alter the way quit and nickchange messages are displayed. For example, the theme I use contains (among other things):

formats = {
  "fe-common-core" = {
    quit = "%K[-] $0 quit -- $2%N";
    nick_changed = "%B** $0 is now known as $1";
  }
}

Perhaps there's another way to achieve per-channel filtering of nick and which is less brittle.

Filter channel mode changes associated with join/parts

I'm using smartfilter in combination with irssi-xmpp. It helps me get rid of join/part spam, but I'm left with user specific channelmodes that are set upon join.

E.g. 13:35 -!- mode/[email protected] [+p user] by [email protected]

Is ignoring channelmodes that are related to join/parts something that you would be interested in? I would imagine this to be useful for irc in general (e.g. 13:36 -!- #chan [+o foo] by bar), not just for my xmpp use-case, though the applicable modes are likely to differ.

Activate the script only in some channels

Hello,

Would it be possible to hide the join/parts only in specified channels?
In small private channels, hiding join/parts is inconvenient.

Cheers

Solved.

Not an issue anymore.

Should count the activity of queries or ignore them for filtering

Currently the script doesn't count the activity in a query so if a person who you are actively talking with in a query quits you won't see the event at all, neither in the channel or the query. This should be addressed.

Filter Netsplit quits

Hi,

Right now Netsplit quits are still displayed with irssi-smartfilter. It would be great if there were an option to hide them as well.
