slackbot

Extensible, PHP-based bot for Slack, using Slack's Real-Time Messaging API, using Yii 2.0. Work in progress.

Requirements

1. PHP >5.6.8 OR PHP >5.5.20 (untested.. but it should work)
2. PHP Modules: mbstring, pdo, mysql, xml
3. OpenSSL development headers (openssl-devel on centos)
4. libevent2 compiled and installed AFTER openssl headers installed: http://libevent.org/
5. pecl event module installed with SSL support

Getting Started

1. import schema.sql into a new database
2. move config/db.php.example to config/db.php and update it with your database info.
3. INSERT INTO config VALUES ('slack.apikey', 'YOUR_SLACK_XOP_KEY'); at minimum. Other keys are needed for some commands to function.
4. run composer update
5. bin/bot start

Optional/Recommended Configuration

In order for some commands to work, you will need to set the following in the config table:

1. For WolframAlpha, INSERT INTO config VALUES ('wa.appid','YOUR_WOLFRAM_APP_ID');
2. For Imgur, INSERT INTO config VALUES ('imgur.client_id','YOUR_IMGUR_CLIENT_ID'), ('imgur.client_secret','YOUR_IMGUR_CLIENT_SECRET');

Using the Bot

Slackbot comes with a number of built in commands. You can inspect the files in components/Slack/Event/Message/ for more details, but here's a short list. Note that most of these commands need the bot's name in front of them (i.e. bot: roll 1d20)

1. roll: roll dice. syntax bot: roll [number of dice]d[die side count][, ...]
2. reaction: paste a reaction gif based on your text. requires imgur configuration. example bot: reaction deal with it
3. ping: make the bot respond with pong and the time it took to respond in ms (from the bot's perspective). bot: ping
4. WolframAlpha questions. This one is a bit freeform, but asking the bot 'what is' 'how is' etc questions should generate a response from W|A. you need W|A config in your config table. example: bot: what is the square root of pi?
5. wa: get a more detailed response from Woldfram, or ask something without having to form it into a question. example: bot: wa 192.168.0.0/21
6. asl: print a randomized silly A/S/L response. bot: asl?
7. password generator. ask the bot to generate you one or more passwords, which will be IMed to you. examples: bot: give me a password, bot: give me 5 passwords

Using eatpl

eatpl is a small tool for creating new EventAction classes from a TemPLate. (hence e-a-tpl). The syntax is like so:

./eatpl event_name[:subtype_name] nameforyouraction

For example, if you wanted to make a new action for the Message event, with the subtype being bot_message (i.e. an integration's message), you would do:

./eatpl message:bot_message nameofaction

This would create a new file, protected/components/Slack/Event/Message/Bot_messgae/NameofactionEventAction.php, from the highest-level Template.phpt it can find - in this case, in protected/components/Slack/Event/Message/
