xkcd-Bucket

Bucket is one of three bots in xkcd's IRC Channel. The source is available here, which includes a sample database with a minimal configuration.

The full database is not publicly available.

What is Bucket?

Bucket is a bot that can be taught factoids that will be triggered when certain phrases are said. The full documentation is available here, but this document will serve as a quick overview of some of Bucket's functionality.

Bucket must be addressed to be taught factoids, either as "Bucket:" or "Bucket," (or whatever you choose to name your instance), most clients should do this by tab-completion.

Installing

1. Clone this repository.
2. Set up a MySQL database, other databases may work but are not guaranteed to do so. $ sudo apt-get install mysql-server *Replace this appropriately depending on your operating system.
3. Create the tables in bucket.sql. You may need the arguments --user=root --password in order for it to work.

   $ mysql -D bucket < bucket.sql
   $ mysql -D bucket < sample.sql```
   

4. Create a user for Bucket, and grant all perms on the bucket database. $ echo 'grant all on bucket.* to bucket identified by "s3kr1tP@ss"' | mysql
5. Edit config file
6. Copy bucket.yml.sample -> bucket.yml
7. Edit bucket.yml and save
8. Install perl modules.

   Lingua::EN::Syllable YAML HTML::Entities URI::Escape XML::Simple```
   

9. Set bucket.pl as executable. $ chmod +x bucket.pl
10. Pre-flight checklist
11. Register your Bucket's nick with NickServ
12. Register your Bucket's logging and config channels, and configure them as private and restricted.
13. Add your Bucket's nick to the allow list for the logging and config channels.
14. Start Bucket. $ ./bucket.pl
15. Start adding factoids!

What can Bucket do?

This is only a brief overview, the full documentation is here.

Factoids

X is Y

This is the most common and basic method of teaching Bucket factoids, it is added by simply saying X is Y. If "X" is said later, Bucket will reply with "X is Y". Be careful, though, as it is also easy to accidentally create factoids this way. X is also Y will have the same effect.

X is Y is Z will be split between X and Y, and Bucket will respond to the trigger "X" with "X is Y is Z." X is Y <is> Z must be used for "X is Y" to trigger "X is Y is Z." See the section on s below.

X are Y

This is used identically to X is Y, with the exception being that Bucket will respond to "X" with "X are Y."

X <verb> Y

Bucket is smart enough to know verbs! X loves Y and similar phrases will cause X to trigger "X loves Y."

X<'s> Y is a special variant of this, making "X" trigger "X's Y."

X <reply> Y

Perhaps the second-most used factoids are X <reply> Y factoids. Saying "X" will make Bucket respond "Y."

X <action> Y

This will make Bucket use a /me when he replies. Thus, saying "X" will make Bucket /me Y.

Commands

Bucket is not a client! Teaching him factoids such as Quit <reply> /quit will not work as intended.

Quotes

Bucket has the ability to remember things that users have said. Remember {nick} {snippet_from_line} will remember that user's line under the trigger "nick quotes."

Searching and Editing

Listing

literal X will list all the factoids associated with that trigger, separated by |. If there are too many, Bucket will automatically create a new page and append "n more." literal[*p*] X will list page number p.

literal[*] X will make Bucket produce a URL of a text file with all of the associated factoids.

X =~ /m/ will make Bucket reply with the first factoid in trigger "X" containing "m."

"what was that?" will make Bucket list the last spoken factoid with all of its details: "That was X(#000): Y", the number being the factoid ID.

Editing

X =~ s/m/n/ will replace "m" with "n" in the trigger "X." X =~ s/m/n/i (adding an "i" flag) will replace case-insensitively. If there is more than one appearance of "m" in "X," it will replace the first instance. Channel operators can add a "g" flag to replace all.

undo last undoes the last change to a factoid. Non-ops can only undo last if they made the last change.

Variables

Variables will only work in responses.

$noun and $nouns will add random noun(s) where they are placed.

$verb, $verbed and $verbing will do similarily with verbs.

$adjective and $preposition have similar effects.

$who will be replaced with the person who triggered the factoid, while $someone will choose a (semi-)random user.

$to will be replaced by the intended recipient, for example, <someuser> anotherguy: blah blah will replace $to with "anotherguy."

Bucket also has gender variables (among other variables.) They can be found here.

Inventory

Items can be put in Bucket, given to Bucket, or items given to Bucket. Bucket is also smart enough to understand posession, and will add "username's item" appropriately. Bucket's inventory can be listed with the command inventory.

Ops can delete items using detailed inventory and delete item #x.

$item, $giveitem, and $newitem are all variables concerning items. $item will use an item in Bucket's inventory, $giveitem will use an item and discard it, and $newitem will use a random item from previously learned items.

Special Factoids

Bucket also has some factoids for hard-coded uses. These include "Don't Know", "Automatic Haiku" and "Band Name Reply."
