The ScrollZ IRC Client User Guide

by JustMe_

Updated by Flier

This document describes how to install and use ScrollZ IRC client. It is the first document which a new ScrollZ user should read to get things started.


Legal aspects

This document is provided as is. I put great effort into writing it as accurately as I could, but you use the information contained in it at your own risk. In no event shall I be liable for any damages resulting from the use of this work.

Purpose of this document

ScrollZ is an advanced IRC client based on ircII client. It was developed on Linux, but can be compiled on variety of Unix platforms.

This document assumes that you have heard of and know about ScrollZ, and now want to sit down and use it. Those of you who don't know what IRC is shouldn't be reading this document, really.

New versions of this document

New versions of the ScrollZ IRC Client User Guide will be periodically updated on ScrollZ home pages.

Quoting and stuff

To make things more understandable I opted to enclose all multi word phrases in pairs of '', like 'This is really stupid.'. So if I say one has to type 'blah blah', they should really type blah blah without ' characters. This also avoids confusion when phrase ends with '.' and people are desperately trying to type the '.' character as well.

What is ScrollZ anyway ?

Basically ScrollZ is ircII client plus it adds a lot of features found in all sorts of scripts. You should be aware that the main difference between these scripts and ScrollZ is the code - whereas ircII scripts take a lot of disk and memory space and run slow, ScrollZ only takes a couple of extra kilobytes compared to stock ircII client yet runs faster than any ircII script. This was accomplished by using C code instead of ircII scripting language. This reduces memory and CPU usage and code tends to run way faster. Besides that, scripts also take long time to load since most of them are larger than 100k in size.

Here is a list of most important features :

  • supports colors
  • internal userlist and shitlist
  • a lot of things are stored in memory, so we don't have to contact
  • server at all in some cases
  • improved file exchange (based on Sheik's cdcc.c)
  • improved cosmetics (based on TooLie Box by Zakath)
  • improved flood protection
  • adds channel protection
  • comes with user-friendly options like tab key, auto reply and URL catcher
  • logs events important to you when you're away (customizable)
  • adds OperVision (optional; coded by Zakath)
  • supports virtual IP

As I have already said ScrollZ is ircII so everything that can be done in ircII can be done in ScrollZ too and all ircII scripts work without a problem (old scripts have to be converted to UTF-8 character set). NOTE: there is no ICB support nor DCC TALK support in ScrollZ so the ircII ICB or DCC TALK related stuff does NOT work!

Installing it

Read INSTALL.ScrollZ file located in doc subdirectory.

Setting up '.ScrollZ' directory

By default the first time you run the client it will create directory named '.ScrollZ' in your home directory together with an empty ScrollZ.save file. You can use another directory if you wish so, make sure you 'set load_path' in that case. The default mode for newly created '~/.ScrollZ' directory is 700 so other users can not read your ScrollZ files. You should put files like ScrollZ.addon and/or your scripts in there. Scripts can be placed in any other directory as well but that will require path to script to be supplied in '/load' command.

Setting up '.scrollzrc'

Second thing to do is to create file called '.scrollzrc' in your home directory. You can use your favourite editor to create one. It should contain at least the following line: 'set load_path ~/.ScrollZ'. In reality one doesn't have to set load_path if their ScrollZ dir is ~/.ScrollZ because the client itself will do that for them. Of course one has to type in another directory if they opted to use another directory for ScrollZ stuff in step 3.1. If you want to use ScrollZ help files and keep them in directory other than /share/scrollz/help/ be sure to add something like 'set help_path /home/user/irc/help/'.

Coexistence with other IRC clients

ScrollZ will co-exist with other IRC clients such as ircII, Ctoolz or BitchX. Main thing how to accomplish this is by keeping each IRC client's files in their own directory. And as they can all use their own '~/.xxxrc' file users can safely use all of them at the same time.

Choosing compile time options

I assume the source for your copy of ScrollZ client is one of the people from ScrollZ distro team. Now maybe they haven't notified you about this, but ScrollZ can be compiled in many ways which either add or remove some of the functionality. If you want to customize your copy of ScrollZ you will have to persuade your distro person to compile it for you. I leave it up to you to think of the way to do that ;^). Here's list of compile time options - some of them useful some of them not:

Option       Flag   Description
WANTANSI     A      enables colors
EXTRAS       E      adds a lot of commands like : autoinv, bki, bkt,
                    dirlmk, dirlnk, dobans, llook, llookup, massdv,
                    massv, modelock, modeunlock, msay and ranlk.
BETTERTIMER  T      timer accurate to 0.01s (default accuracy is 1s)
GENX         G      different look of whois
NEWCSCAN     C      formatted cscan, similar to that of BitchX
ACID         I      invite on notify for non +i channels
SORTEDNICKS  N      sorted nicks in cscan
SCKICKS      S      scatter (funny) kicks
OPERVISION   OV     for IRC Opers
CELE         cy     compile with celerity in client
HYPERDCC     D      compile with HyperDCC (faster DCC) by Annatar
VILAS        V      no ScrollZ trademarks in kicks and away msgs
JIMMIE       J      better newhost command
CTCPPAGE     P      CTCP PAGE for friends by Bighead
TDF          X      different msgs, chat msgs and CDCC
COUNTRY      Y      adds $country() function
OGRE         Z      different OV cosmetics
OPER         OPER   for IRC Opers

You can check which options was your copy of ScrollZ compiled with by typing '/version' and look for string enclosed in []'s. Scripts can check for availability of certain features by examining the value of '$J'. Upper case letters mean that option was disable while lower case letters denote disabled options.

Setting up environment variables

ScrollZ is aware of following environment variables:

  • IRCNICK - sets nick
  • IRCSERVER - sets servers to use
  • IRCHELP - sets path to ircII help directory
  • IRCLIB - sets path to irc lib directory
  • IRCUMODE - sets user mode
  • IRCNAME - sets gecos (shown in whois)
  • IRCPATH - much like 'set load_path'
  • IRCHOST - sets virtual host
  • IRCUSER - sets username (if your ident allows it)
  • IRCRC - sets rc file (instead of .scrollzrc)
  • IRCQUICK - sets quickrc file (instead of .scrollzquick)
  • DCCHOST - IP address for DCC sends
  • VIRTIP - sets IP address for client (system wide)
  • HOME - sets home directory
  • MAIL - sets mail file
  • TERM - sets terminal type
  • USER - sets username (if your ident allows it)

Usually they can be set in ~/.profile file like this :

a) for bash, ksh, zsh and sh users : IRCNICK="Nick" IRCSERVER="irc.server.com:port irc.server.org[:port]" ... export IRCNICK IRCSERVER

b) csh and tcsh users : setenv IRCNICK "Nick"

3.6. Setting up things under Windows

It is possible to compile and run ScrollZ under Windows using excellent CygWin product which is available for free from Cygnus. The compile process is exactly the same as under any U*IX platform using the configure script (see above for details). Once you have compiled the binary, create a directory that will hold ScrollZ :

cd \
mkdir ScrollZ

and copy scrollz.exe to this newly created directory. Optionally you can also copy the help directory to this directory. Now create a batch file called scrollz.bat that will be used to run the client with the following content :

set HOME=/cygdrive/d/ScrollZ
set IRCPATH=/cygdrive/d/ScrollZ
set IRCHELP=/cygdrive/d/ScrollZ/help
set IRCNICK=myircnick
set IRCSERVER=irc.server.com:port

Note that you should replace d in the batch file above with the drive letter that holds your ScrollZ directory. Now you should be able to run ScrollZ by executing scrollz.bat.

ScrollZ features

To start with let me just say I'm not going to explain every possible option out there but will rather focus on basic concepts of using it. Best way to learn all of its options is (like always) to use it for real - that way you will learn all about it. We will only deal with ScrollZ commands in this document and little or none attention will be payed to regular ircII commands. And remember, '/help' is your friend.

'ScrollZ.save' file

When you first start ScrollZ you should type '/sve' which will save all current options to 'ScrollZ.save' file located in first directory found in load_path variable. 'ScrollZ.save' file is a plain text file - thus it can be edited with every editor. But you will hardly ever need to edit it by hand, most of the settings can be changed via ScrollZ commands.

Here are exceptions to this rule :

  • DEFSERVER - sets default server (for /S command)
  • DEFSIGNOFF - sets default sign-off message
  • DEFSETAWAY - sets default away reason
  • DEFSETBACK - sets default back reason
  • DEFUSERINFO - sets default user info reply (CTCP)
  • DEFFINGER - sets default finger reply (CTCP)
  • DEFK - sets default kick message
  • DEFBK - sets default ban-kick message
  • DEFBKI - sets default ban-kick-ignore message
  • DEFBKT - sets default ban-kick-time message
  • DEFFK - sets default filter-kick message
  • DEFLK - sets default lame-kick message
  • DEFABK - sets default auto-ban-kick message
  • DEFSK - sets default scatter-kick message
  • DEFKILL - sets default kill message

You can edit 'ScrollZ.save' file in order to change those options. Don't forget to do '/reload' after editing file for changes to take effect.

Friends + Shit list

Why friends list ? Why shit list ? It started when people wanted to "keep" control of channels they were hanging in and having friends and shit list helped them in a big way. People that are on your friends list can benefit from it by being auto-opped, auto-voiced etc. while shit list makes sure that those who you hate stay away from your channel(s). ScrollZ's user list is channel aware - meaning that user can have separate friends list entry for every channel you want.

Commands that control friends list are :

  • addf - add person to friends list
  • addfflag - add flag to friends' list entry
  • addfchan - add channel to friends' list entry
  • frlist - sets friends list on/off
  • listf - list people on friends list
  • remf - remove person from friends list
  • remfflag - remove flag from friends' list entry
  • remfchan - remove channel from friends' list entry

Commands that control shit list are :

  • addbk - add person to shit list
  • bklist - sets shit list on/off
  • listbk - list people on shit list
  • rembk - remove person from shit list

Also be sure to read '/help levels' for more info on flags.

Notify list

ScrollZ can notify you when certain nicks signs on/off. To select which nicks do you want to be notified about use these commands :

  • addn - add person to notify list
  • listn - list people on notify list
  • remn - remove person form notify list
  • ntfymode - toggle brief or verbose mode of '/listn'

Channel protection

You can make ScrollZ "protect" channel from nasty stuff like mass deop, mass kick and the likes with this commands :

  • dprot - sets deop protection on/off
  • deops - sets deop protection sensor
  • deopt - sets deop protection time
  • kprot - sets kick protection on/off
  • kicks - sets kick protection sensor
  • kickt - sets kick protection time
  • nprot - sets nick flood protection on/off
  • nicks - sets nick flood protection sensor
  • nickt - sets nick flood protection time
  • kickonflood - sets kick-on-flood protection on/off
  • addw - add word to word kick list
  • listw - list words on word kick list
  • remw - remove word from word kick list
  • idlekick - kick idle users from a channel
  • idletime - sets idle kick timeout

Netsplits, nethacks and netjoins

This is one of the features where ScrollZ really excels. It is entirely controlled via '/nhprot' command - so '/help nhprot' for more info. If you have this option turned on you better make sure your userlist is pretty complete (most of regular channel ops should be on it) or else you will not be very popular channel op.

DCC - sending and receiving files, dcc chat

ScrollZ is based on ircII and it has the same command as ircII for controlling DCC stuff (that is '/dcc'). But it also features '/cdcc' command which is by far more powerful and user friendly. So I suggest you to forget about '/dcc' and use only '/cdcc' + '/chat' and '/nochat'. Again everything is explained in help, so let me just remind you of '/help cdcc get' which will show you examples on how to use that fancy filter for selecting dccs. And be careful with '/cdcc autoget' being turned on! Oh yeah, some people don't like to see others flooding channels with their offer lists - so better set '/cdcc channels' and '/cdcc ptime'.


Apart from ircII logging ScrollZ has logging on its own too. For more info try '/help awaysave'. Normally ScrollZ would log events to 'ScrollZ.away' only if you're set away - but you can change this with '/logon' command. You can set the file to log to by modifying the AWAY_FILE variable (example: '/set away_file ~/.away.log').

Other useful hints

Small things that will make your life with ScrollZ easier are :

  • get used to Tab key - what the hell is that you ask ? Well let me show how to use it. Say you want to send a file to 3 people from your current channel. Go and type '/cdcc send file1 file2, n1 n2 n3' where "n1", "n2" and "n3" are first two letters of first, second and third nick, respectively. Get it ? It expands the last word to nick if it finds a match for first two letters - if more nicks start with same prefix simply press Tab few more times. Of course you don't need to type first two letters of a nick, it can be any number (except 0 of course). You can complete channel names in much the same way.

  • Tab key, it acts much like ircII tabkey script - when someone sends you a msg his/her nick gets stored into an array and if you want to reply to that message just press Tab. ScrollZ will store up to 10 nicks for you. WARNING: this behaviour only works if your input line is empty!

  • turn auto-completion on ('/autocompl on :' for example) and learn how to use it

  • use Ctrl+R key - did you notice different color of nick on public messages which had your nick in them ? That's auto reply and Ctrl+R cycles through last 5 people's nicks that have triggered your auto-reply. You can change your autoreply word with '/repword' command. Hint : having '/repword' set to some very common word (like "just") will fill your away file with meaningless messages (for you) if you have AREPLY in your '/awaysave' setting. So add lines like this : 'alias setaway {^repword justme_ ;//setaway}' and 'alias setback {//setback ;^repword just,jm}' to '~/.scrollzrc'.

  • you hang in more channels and want each one in its own window ? Here's little alias to help you :

    alias wc { if ([$0]==[]) { echo $scrollz_string Usage : /WC [#]channel } { if ([$left(1 $0)]!=[#]) {^assign winchan #$0} {^assign winchan $0} echo $scrollz_string Creating new window for channel $winchan window new bind $winchan j $winchan window hide } ^assign -winchan }

    You also want channels to be in the same window all the time ? Ok add this to your '~/.scrollzrc' file :

    ^on -join_me "#chan1" window swap 1 bind $0 ^on -join_me "#chan2" window swap 2 bind $0 ^on -join_me "#chan3" window swap 3 bind $0

    This will bind #chan1 to window 1, #chan2 to window 2 and #chan3 to window 3.

    You have bot on channel and want to identify to it automatically without your intervention ? Add this to '~/.scrollzrc' :

    on -channel_synch "#chan" { if ([$ischanop(botnick $0)]==[1] && [$checkuser($uh(botnick) $0)]!=[-1]) { m botnick identify password m botnick op } }

    Change botnick to your bot's nick and make sure bot is on your friends list (flags don't matter).

  • if you want ScrollZ to automatically join certain channels use '/ajoin' command like : '/ajoin auto #chan1,#chan2' - ScrollZ will try to join #chan1 and #chan2 every 10 minutes (if you haven't already joined those channels of course).

  • if you don't want to be automatically set away after certain amount of time elapses without your activity do '/awayt 0'. Some channels don't like clients announcing they're away/back and you can control that with '/showaway'.

ScrollZ key bindings

Most of the key binds are the same as in ircII, here's a list of those that aren't :

Miscellaneous stuff

How to enable DCCs if you are behind a firewall

This is dependant on your firewall of course. Example will be given for Linux 2.4.x kernels using iptables. Nevertheless the aproach is generic enough so it can be applied to other types of firewalls. Note that we don't use the ip_conntrack_irc kernel feature! In the example ports 50000 to 50010 will be allowed for the DCC. Whenever we say <router_ip> we mean the IP address that is visible on the Internet. Whenever we say <internal_ip> we mean the IP address that is visible on the LAN (they could be the same if you are not using NAT or IP masquerading).

  1. We have to allow packets to ports 50000-50010: iptables -I INPUT -p tcp -s 0/0 --dport 50000:50010 -j ACCEPT

    If your firewall configuration is more sophisticated (NAT or IP masquerading) you have to redirect incoming packets on ports 50000-50010 to the internal_ip ports 50000-50010 (we assume the incoming packets on Ethernet interface eth1): iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 50000:50010
    -j REDIRECT --to <internal_ip>

  2. Tell the client to announce the router's IP address in the DCC requests: for ksh, sh, zsh, bash: DCCHOST="<router_ip>" export DCCHOST for csh, tcsh: setenv DCCHOST "<router_ip>"

  3. We tell the client to only use ports 50000-50010 for the DCC stuff: /set dcc_ports 50000-50010 (or 50000:50010)

How to connect via bouncer to multiple IRC networks

Suppose you have a shell account where you run IRC bouncer (a better name would be IRC proxy I guess) and connect to multiple IRC networks via it from your home machine. The problem is you can't connect to more than one IRC network from within the same client (it is an ircII limitation where you can't connect twice to the same server:port combination). You can work around this limitation, however. Here is what you have to do (on Linux at least, should work also on Solaris and HP-UX):

  1. The IRC bouncer is running on shell.domain.com

  2. Edit /etc/hosts on your home machine and add the following entries: shell_ipefnet.domain.com shell_ipircnet.domain.com shell_ipundernet.domain.com Insert the IP address of your shell in place of shell_ip. Where it says press TAB key. Change efnet/ircnet/undernet to whatever you prefer.

  3. Edit /etc/nsswitch.conf on your home machine and make sure the entry for hosts looks like this: hosts: files dns

  4. Run ScrollZ and do /server efnet.domain.com:bouncer_port Additionally do /net ircnet.domain.com:bouncer_port

    Now it works fine - you can connect through IRC bouncer to more than one IRC network from within the same client.

How to fix terminal size in screen

If you are attaching to a screen session in a terminal whose size is different from the terminal size when you detached screen, client might be confused about the terminal size. Here is how to fix it:

  1. Identify the terminal device client is using (ps -ef | grep scrollz)
  2. stty -F /path/to/terminal/device cols X rows Y where /path/to/terminal/device is the full path to the terminal device your client is running on, X is number of columns and Y is number of rows (example: stty -F /dev/pts0 cols 80 rows 38)

The above works at least on Linux, for other platforms you might have to read the manual page for stty command.
