dvdgbot

This is my personal playground for IRC bot stuff in Go. It will probably not be directly usable for others, but one might find bits and pieces that can be modified and reused.

It currently has some submodules that can be enabled/disabled by imports in main.go:

• leet:
  • This is the main motivation for the whole bot. It's a game.
  • Triggered by: !1337 [stats|reload]
  • See separate documentation.
• quoteshuffle:
  • Not a bot module. Just a helper lib. Could be used for anything else that fits, though.
  • Takes a JSON file with quotes (or whatever strings), and returns a random quote from the list.
  • To avoid often getting the same quotes, it will move the returned quote from the src array to the dst array, and when the src array is empty, all quotes are moved back to the src array from the dst array. This way, you won't see the same quote again until all others have been shown.
  • JSON format:

    {
      "src": [
      	"quote one",
      	"quote two",
      	"..."
      ],
      "dst": [
      ]
    }
    

• larsmonsen:
  • Based on https://github.com/go-chat-bot/plugins/chucknorris but has text from larsmonsenfacts.com
  • Triggered by the words "lars" or "monsen" (case insensitive) anywhere in a channel message.
  • Text is saved in a separate JSON file, shuffled and rotated by the quoteshuffle module.
  • Defaults to loading facts from /tmp/larsmonsenfacts.json, but can be overridden by the env var LARSMONSENFACTS_FILE
• timestamp:
  • Just prepends a detailed timestamp to a message.
  • Triggered by the prefix command !ts
• tool:
  • This is just a helper for Makefile, to make it easier to get the same date format both on Linux/OSX/Windows. Not used by the bot itself.
• userwatch:
  • Lets you add welcome/bye messages for given nicks for JOIN/PART/QUIT.
  • Loads and saves config in /tmp/userwatch.json. Override can be done through the InitBot method, which you must call within main() in main.go. See commented code in main()for an example.
  • See separate documentation.
• xkcdbot:
  • Returns the image URL for an XKCD comic.
  • Triggered by: !xkcd get <ID>|latest

Customize

You may customize witch submodules you want to include. Mostly, it's just a matter of an underscore import, but some modules requires extra steps.

Building

First, get your local copy of this repo:

$ git clone https://github.com/oddlid/dvdgbot.git
$ cd dvdgbot

Then, you can build a binary directly on your machine, if you have Golang installed, or you can build in Docker.

Build locally

$ make

Or, if you want the binary to be named something else than dvdgbot.bin, run:

$ make BINARY=mycoolbot (replace "mycoolbot" with desired name)

Build in Docker

If you've already built a binary with make as above, and would like to make a Docker image out of it, do like this, assuming you go with the default binary name:

$ docker build -t <repo>/<image_name>:<tag> -f Dockerfile.local .

Or, if you built with another binary name:

$ docker build -t <repo>/<image_name>:<tag> --build-arg BUILD_BIN=mycoolbot -f Dockerfile.local

If you just want to build a Docker image directly, without the intermediate step of a local binary, run:

$ docker build -t <repo>/<image_name>:<tag> .

Or if you want the binary to have some other name inside the Docker image, run:

$ docker build -t <repo>/<image_name>:<tag> --build-arg BUILD_BIN=mycoolbot .

Get pre-built docker image

I have a Docker image of this at Docker Hub, but that's configured with(out) the modules I currently use at the time of pulling. If that's fine by you, just run:

docker pull oddlid/dvdgbot:latest

...and you'll get my latest build ready for use. It builds directly from github (this repo), so what you see in the code, is what you get.
