Since 2009, the Haskell channel has grown large enough that we've split it in two parts:
  +
  +
* #haskell, for all the usual things
  +
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion
  +
  +
As always, #haskell remains the primary place for new user questions.

Revision as of 02:47, 28 April 2015

Internet Relay Chat is a worldwide text chat service with many thousands of users among various irc networks.

The Freenode IRC network hosts the very large #haskell channel, and we've had up to 1046 concurrent users, making the channel consistently one of the most popular of the thousands of channels on freenode. One famous resident is Lambdabot, another is hpaste (see the Bots section below).

The IRC channel can be an excellent place to learn more about Haskell, and to just keep in the loop on new things in the Haskell world. Many new developments in the Haskell world first appear on the irc channel.

Since 2009, the Haskell channel has grown large enough that we've split it in two parts:

  • #haskell, for all the usual things
  • #haskell-in-depth , for those seeking in depth, or more theoretical discussion

As always, #haskell remains the primary place for new user questions.

Getting there

If you point your irc client to chat.freenode.net and then join the #haskell channel, you'll be there. Alternately, you can try http://java.freenode.net/ or http://webchat.freenode.net/ which connects inside the browser.

Example, using irssi: 

   $ irssi -c chat.freenode.net -n myname -w mypassword
   /join #haskell

Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out ERC, The Emacs IRC client. Invoke it like this and follow the commands: 

   M-x erc-select
   ...
   /join #haskell
A screenshot of an irssi session in #haskell

Principles

The #haskell channel is a very friendly, welcoming place to hang out, teach and learn. The goal of #haskell is to encourage learning and discussion of Haskell, functional programming, and programming in general. As part of this we welcome newbies, and encourage teaching of the language.

Part of the #haskell success comes from the fact that the community is quite tight knit — we know each other — it's not just a homework channel. As a result, many collaborative projects have arisen between Haskell irc channel citizens.

To maintain the friendly, open culture, the following is required:

  • Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.
  • Helpful answers should be encouraged with name++ karma points, in public, as a reward for providing a good answer.
  • Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. Socratic questioning), rather than challenging the competence of the writer (ad hominem). As the channel grows, we see a diverse range of people with different programming backgrounds getting accustomed to Haskell. Be patient and take satisfaction from spreading knowledge.

History

The #haskell channel appeared in the late 90s, and really got going in early 2001, with the help of Shae Erisson (aka shapr).

Related channels

In addition to the main Haskell channel there are also:

Logs

Logs are kept at http://tunes.org/~nef/logs/haskell/ and can be searched at http://ircbrowse.net/browse/haskell


Bots

There are various bots on the channel. Their names and usage are described here.

lambdabot

Lambdabot is both the name of a software package and a bot on the channel. It provides many useful services for visitors to the IRC channel. It is available as a haskell package and can be integrated into ghci. Details on the software are found on a separate wiki page.

Here is its interface for the IRC user:

lambdabot's commands are prepended by a '@' sign.

Command Usage
@help display help to other commands, but help text is not available for all commands.
@type EXPR or ':t' EXPR shows the type of an expression
@kind TYPECONSTRUCTOR shows the kind of a type constructor
@run EXPR or '>' EXPR evaluates EXPR
@pl FUNCTION shows a pointfree version of FUNCTION
@pointful FUNCTION or '@unpl' FUNCTION shows a 'pointful' version of FUNCTION
@tell <nick> <msg> -- same as @ask Next time <nick> speaks in channel they will be notified they have a message pending and how to receive it.

preflex

is the name of a lambdabot with more commands/plugins enabled. It is run by ?? To talk to preflex, write preflex: command ARGS

Command Usage
help COMMAND displays help to other commands.
list lists all plugins with their commands
NICK++ / NICK-- in/decrements the karma of NICK.
karma NICK shows the karma of NICK
seen NICK shows information about the last message of a user
tell / ask sends NICK MSG a message when she becomes active.
xseen see 'seen' ?? any difference ?
quote NICK prints a random quote of NICK
remember NAME QUOTE associates NAME with quote. can be accessed by 'quote'
... ...

hpaste

The hpaste bot provides a notification interface to the hpaste pastebin. Emacs integration is available.

Usage?

Not online often !?

hackage

The hackage bot provides real-time notifications of new package uploads to Hackage.

Locations

To get an overview of where everybody on the channel might be, physically, please visit Haskell user locations.
