Slack IRC client

Work in progress. Proceed with caution. Testers and contributions are welcome.

Slack IRC client is a node.js application that acts as an IRC client as well as a Slack client, bridging communication between the two networks for a single user.

It differs from the splendid ekmartin/slack-irc gateway in that instead of syncing messages for all users on a single channel, slack-irc-client syncs all messages for a single user on all channels.

Features

Chat on any IRC channel form your favorite Slack client
Send and receive IRC queries
Channel topics are synced both ways
Status messages delivered to Slackbot DM chat
Configured through Slack user and channel metadata

Instructions

Installation

Create new Slack team at https://slack.com/create
- Don't invite anyone else to the team
- Adding multiple users will lead to duplicate messages being sent to IRC
Remove the default channels, create and join the Slack channels you want to join in IRC
Set configuration in your user profile "What I do field" at https://slack.com/account/profile
- JSON formatted string with the following fields
  - server: IRC server to connect to
  - port: Port to connect to (defaults to 6668)
- All fields will be passed to node-irc
- For example:
```
{
  "server": "open.ircnet.net",
  "port": 6668,
  "userName": "aeirola"
}
```
- Optionally, a string field nsPassword will cause the bot to send /msg Nickserv IDENTIFY ${nsPassword} after 5 seconds of being connected which is the correct format for freenode's nickserv. Other nickservs may not like this format, but it's a start.
Generate a Test token for your newly created team at http://aeirola.github.io/slack-irc-client/
Install slack-irc-client from npm
```
npm install -g slack-irc-client
```
Start the gateway with
```
slack-irc-client -t ${SLACK_API_TOKEN}
```
Chat from your Slack!

Upgrade

Update the npm package:
```
npm update -g slack-irc-client
```
Reload the code by entering the command reload in the terminal running the application

Usage

Once everything is set up, normal usage of IRC through Slack should be pretty straightforward chatting. Messages are sent and received, topics are synced and so forth. Here are some special cases that might need additional instructions though.

Joining channels

Normal channels with names that adhere to Slacks channel naming convention (max 21 chars, alphanumerics underscore or dash) can be joined by just creating the channel in Slack. Leave out the preceding # in the name.

If you need to join other types of channels, you need to add a channel configuration in the channel "Purpose" field. The value of this field should be a JSON formatted string containing the following fields:

channelName: The IRC channel name to use

For example:

{
  "channelName": "!CUCREslack-irc-client"
}

Warning: Due to an issue in how Slack updates the channel purpose only after channel creation, the plain channel name will be joined in IRC on first creation of the channel. You need to leave this channel in Slack and join it again to join the correct IRC channel.

This can also be used if you just want the channel name to show differently within Slack.

Ignoring JOIN, PART, QUIT, etc.

To ignore various messages, you can configure your What I do JSON object to include the muteIrcEvents field:

{
  "server": "open.ircnet.net",
  // ...
  "muteIrcEvents": ["join", ...]
}

And you'll no longer see these messages in your Slack channels.

Valid values for this field are as follows:

Value	Description
`join`	Mute JOIN messages in the channel
`kick`	Mute KICK messages in the channel
`kill`	Mute KILL messages in the channel
`motd`	Mute MOTD direct messages from slackbot on join
`names`	Mute membership list in the channel on join
`part`	Mute PART messages in the channel
`quit`	Mute QUIT messages in the channel
`topic`	Don't set the topic in the channel on join

Sending direct messages

If an IRC users sends you a direct message, a new Slack group chat will be created for your 1-to-1 chat with the IRC user. No action is needed on your part.

If you want to initiate a 1-to-1 chat with an IRC user that has not yet sent you an message, you need to create a new Slack group chat with the nick of the IRC user you want to contact.

Additional IRC options

Since the What I do field is directly parsed into a JSON object, you can supply additional commands, listed at the node-irc API documentation. For example, if you want to connect with SASL, which you might need to from an AWS server to Freenode, your configuration could look like the following,

{
     "server": "irc.freenode.net", 
     "port": 6697, 
     "userName": "NICKNAME", 
     "nsPassword": "PASSWORD", 
     "sasl": true, 
     "nick": "NICKNAME",
     "password": "PASSWORD", 
     "realName": "MY REAL NAME", 
     "secure": true 
}

Which will set sasl to true, along with enabling SSL. Of course you need to replace the placeholders above with your own settings.
