slack-to-irc bridge

This code is for slack to IRC bridge, also vice versa. You can build personal IRC client with slack. Original code is forked from https://github.com/voldyman/slack-irc-bridge.

not implemented

not implemented IRC's user listing browsing. also, no DCC or chat function. only for generic channel chat.

building

just clone source, go get and go build.

Usage

# using environment variables
./slack-irc-bridge

# with a custom config file
./slack-irc-bridge [configuration_file]

If you want to use slack as your personal IRC client, -> make channel in slack, mapping to irc channel. (set off relay option) if you want to migrate from IRC to slack, -> make this code run as just bridge. also, you can build automatic invite script.

Configuration

If no config file parameter is specified, configuration is pulled from environment variables.

Environment Variables

The following environment variables are respected:

IRC_URL (default: irc://username:password@irc.freenode.org:6667?relay_nick=true): A DSN containing connection information for irc.
SLACK_URL (default: none, required: true): A slack workspace url in the form https://example.slack.com.
SLACK_TOKEN (default: none, required: true): A slack bot token.
BRIDGES (default: none, required: true): A comma separate list of colon separated slack/irc mappings in the form #slack-channel:#irc-channel.

Config File

default file name is bot.config. if you want to use another name, just add file name as command parameter like ./slack-irc-bridge foo.cfg

bot.config file is json format. you can check it sample.

You can get your slack token from https://api.slack.com/web

{
    "bridges":[
        {"slack":"#general", "irc":"#foo"},
        {"slack":"#slack-channel2", "irc": "#bar"}
    ],
    "irc": {
        "server": "irc.freenode.org:6667",
        "nick" : "bot-nickname",
        "relay_nick": true
    },
    "slack": {
        "url": "https://foo.slack.com",
        "token": "token_here"
    }
}

irc/relay-nick is bool option. if you set true, bot will show your slack nick to IRC. if you use slack as single IRC client, turn off option.
irc/server is IRC server option. this bot doesn't translate code page, so if you are in specific locale environment, use UTF-8 server.
