 4 8f7f2f4a 2021-12-17 jrmu 
 5 8f7f2f4a 2021-12-17 jrmu   In our second lesson, we'll create an IRC bot that greets and interacts
 6 8f7f2f4a 2021-12-17 jrmu   with users.
 7 8f7f2f4a 2021-12-17 jrmu 
 8 8f7f2f4a 2021-12-17 jrmu   Copy the code for autogreet.pl to your home folder:
 9 8f7f2f4a 2021-12-17 jrmu 
10 8f7f2f4a 2021-12-17 jrmu   $ cp autogreet.pl ~/autogreet.pl
11 8f7f2f4a 2021-12-17 jrmu 
12 8f7f2f4a 2021-12-17 jrmu   Next, open up autogreet.pl using a text editor and make a few changes.
13 8f7f2f4a 2021-12-17 jrmu   (We recommend vim because it provides syntax highlighting)
14 8f7f2f4a 2021-12-17 jrmu 
15 8f7f2f4a 2021-12-17 jrmu   1. Edit the server in line 89. Replace irc.example.com with the server's
16 8f7f2f4a 2021-12-17 jrmu      real address. NOTE: Only IPv4 is supported.
17 8f7f2f4a 2021-12-17 jrmu   2. Edit line 92 to replace nickname with the nickname you want for the bot.
18 8f7f2f4a 2021-12-17 jrmu      WARNING: The nickname must not already be taken, or else the bot will
19 8f7f2f4a 2021-12-17 jrmu      fail to connect.
20 8f7f2f4a 2021-12-17 jrmu   3. Edit line 93 to replace username with the username you want for the bot.
21 8f7f2f4a 2021-12-17 jrmu      The username is what appears in a /whois on IRC; it can be different
22 8f7f2f4a 2021-12-17 jrmu      from the nickname.
23 8f7f2f4a 2021-12-17 jrmu 
24 8f7f2f4a 2021-12-17 jrmu   Next, you'll want to make the perl script executable:
25 8f7f2f4a 2021-12-17 jrmu 
26 8f7f2f4a 2021-12-17 jrmu   $ chmod u+x ~/autogreet.pl
27 8f7f2f4a 2021-12-17 jrmu 
28 8f7f2f4a 2021-12-17 jrmu   Then run the script:
29 8f7f2f4a 2021-12-17 jrmu 
30 8f7f2f4a 2021-12-17 jrmu   $ ~/autogreet.pl
31 8f7f2f4a 2021-12-17 jrmu 
32 8f7f2f4a 2021-12-17 jrmu   On IRC, /join #perl102
33 8f7f2f4a 2021-12-17 jrmu 
34 8f7f2f4a 2021-12-17 jrmu   Whenever a user joins or parts the channel, the bot will send a message.
35 8f7f2f4a 2021-12-17 jrmu   Try sending a /me action and a notice in the channel tos ee the bot respond.
36 8f7f2f4a 2021-12-17 jrmu   Lastly, try changing your nick or changing the topic in the channel.
37 8f7f2f4a 2021-12-17 jrmu   What happens?

42 8f7f2f4a 2021-12-17 jrmu 
43 8f7f2f4a 2021-12-17 jrmu   Next, take a look at the file called ~/comments to see an explanation of
44 8f7f2f4a 2021-12-17 jrmu   key lines in the program.
