titlebot

Synopsis

Titlebot is a minimal IRC bot that announces the title of web pages.

Features

• TOML-formatted configuration file with integrity checking using BLAKE2b
• On-the-fly configuration reload upon receiving signal SIGUSR1
• Graceful termination upon receiving signal SIGINT and SIGTERM
• Minimalistic permission system (permitted actions per NickServ account)
• Caching of titles, using both in-memory and persistent databases
• Use of archive.org's API for web pages that would otherwise have the title "Violation of ToS" or the like
• Automatic conversion of YouTube URLs to the form of https://www.youtube.com/embed/ID, and skip looking for an archived version
• Proxy support

For details, please do consult config.toml.example and main.go.

Planned Features

• Parsing of PRIVMSG NickServ :ACC when the IRCd has no account-tag capability

Prerequisites

• github.com/BurntSushi/toml
• github.com/lrstanley/girc
• golang.org/x/crypto/blake2b
• golang.org/x/net/html
• golang.org/x/net/proxy
• zolk3ri.name/go/logger

Getting Started

# Rename `config.toml.example` to `config.toml`:
mv config.toml.example config.toml

Note: do NOT forget to modify config.toml before executing any of the steps below, including deployment with Docker!

# With go version >= 1.11:
go build -mod vendor
# Otherwise you have to `go get <prerequisite>`, then:
go build
# And finally:
./titlebot

Deployment with Docker

docker build -t titlebot .
docker volume create titlebot
docker run -d --name titlebot -v titlebot:/go/src/zolk3ri.name/go/titlebot --restart always titlebot

This will 1) build an image from the Dockerfile and copy your current config.toml to it, 2) create a volume called titlebot for persistent storage, and 3) run titlebot through a daemon that will automatically restart on failure. This will render the configuration setting auto-reconnect pointless. Additionally, expertise in Docker is required to be able to use some of the features, for example the on-the-fly configuration reload, as it relies on sending and receiving signals. You may simply use screen or tmux instead.
