FAQ
|
||||
|
||||
Where is IRC command xy (ignore etc.)?
|
||||
--------------------------------------
|
||||
ii is for advanced users, please use standard tools like awk, sed and grep for
|
||||
this. This can be done easily and will not bloat the code.
|
||||
|
||||
Where is a graphical interface?
|
||||
-------------------------------
|
||||
Basically ii follows the UNIX philosophie so it is only file based. But it
|
||||
should be easy to build different interface because they only have to handle
|
||||
the FIFOs and output files. Feel free to implement or wait until we have done
|
||||
this.
|
||||
|
||||
Which commands are supported?
|
||||
-----------------------------
|
||||
j (join), t (topic), a (away), m (msg), n (nick), l (leave). The missing are
|
||||
obsolete or can be easily used by typing the IRC commands itself (i.e. /WHO
|
||||
instead of /who).

Abstract
|
||||
--------
|
||||
ii is a minimalistic FIFO and filesystem based IRC client.
|
||||
It creates an irc directory tree with server, channel and
|
||||
nick name directories.
|
||||
In every directory a FIFO file (in) and and normal file (out)
|
||||
is placed.
|
||||
The in file is used to communicate with the servers and the out
|
||||
files includes the server messages. For every channel and every nick
|
||||
name there will be new in and out files.
|
||||
The basic idea of this is to be able to communicate with an IRC
|
||||
server with basic command line tools.
|
||||
For example if you will join a channel just do echo "/j #channel" > in
|
||||
and ii creates a new channel directory with in and out file.
|
||||
|
||||
Installation
|
||||
------------
|
||||
Edit config.mk to match your local setup. ii is installed into
|
||||
/usr/local by default.
|
||||
|
||||
Afterwards enter the following command to build and install ii (if
|
||||
necessary as root):
|
||||
|
||||
$ make clean install
|
||||
|
||||
Running ii
|
||||
------------
|
||||
Simply invoke the 'ii' command with required arguments
|
||||
|
||||
To make ii a bit more comfortable use it in combination with the multitail
|
||||
program and for example with vim. Run vim in the server directory and use
|
||||
key mapping like:
|
||||
map w1 :.w >> \#ii/in<cr>
|
||||
map w2 :.w >> \#wmii/in<cr>
|
||||
to post to channels. Thanks to Matthias Kopfermann for this hint.
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
No configuration is needed.
|
||||
|
||||
Contact
|
||||
-------
|
||||
If you want to contact the developers just write a mail to
|
||||

.SH DESCRIPTION
|
||||
.B ii
|
||||
is a minimalistic FIFO and filesystem based IRC client.
|
||||
It creates an irc directory tree with server, channel and
|
||||
nick name directories.
|
||||
In every directory a FIFO file (in) and and normal file (out)
|
||||
is placed. This will be for example ~/irc/irc.freenode.net/.
|
||||
The in file is used to communicate with the servers and the out
|
||||
files includes the server messages. For every channel and every nick
|
||||
name there will be new in and out files.
|
||||
The basic idea of this is to be able to communicate with an IRC
|
||||
server with basic command line tools.
|
||||
For example if you will join a channel just do echo "/j #channel" > in
|
||||
and ii creates a new channel directory with in and out file.
