<hr />
<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />

<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />
<br />
The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

<br />
== Bots ==<br />
<br />
There are various bots on the channel. Their names and usage are described here.<br />
<br />
=== lambdabot ===<br />
<br />
[[Lambdabot]] is both the name of a software package and a bot on the channel. The bot is operated by IRC user <code>int-e</code> and provides many useful services for visitors to the IRC channel. You can interact with it in a private chat or publicly in any channel where it appears (#haskell and a number of others). It is available as a haskell package and can be integrated into ghci. Details on the software are found on a [[Lambdabot|separate wiki page]].<br />
<br />
Here is its interface for the IRC user:<br />
<br />
lambdabot's commands are prepended by a '@' sign.<br />
<br />
{| border="1" cellspacing="0" cellpadding="5"<br />
! Command<br />
! Usage<br />
|-<br />
| @help<br />
| display help to other commands, but help text is not available for all commands.<br />
|-<br />
| @where TOPIC (aliases: @what, @url) <br> @where ? <br> @where+ TOPIC NEWTEXT <br> @where+ TOPIC<br />
| show brief info about some TOPIC <br> list some useful topics (paste, cabalstackhelp, ...) <br> set/update a topic (check for collisions first with @where TOPIC) <br> delete a topic <br />
|-<br />
| @type EXPR or ':t' EXPR<br />

|-<br />
| @run EXPR or '>' EXPR<br />
| evaluates EXPR<br />
|-<br />
| @pl FUNCTION<br />
| shows a [[pointfree]] version of FUNCTION<br />
|-<br />
| @pointful FUNCTION or '@unpl' FUNCTION<br />
| shows a 'pointful' version of FUNCTION<br />
|-<br />
| @tell <nick> <msg> -- same as @ask<br />
| Next time <nick> speaks in channel they will be notified they have a message pending and how to receive it.<br />

* https://github.com/simonmichael/lambdabot-where - git repo and .tsv version of the @where db, updated occasionally<br />
<br />
=== yahb ===<br />
If lambdabot doesn't cut it for you, there is a bot called yahb which runs your request in an actual GHCi prompt, so you can use IO.<br />
<br />
Try e.g. <tt>% readFile "/proc/self/environ"</tt><br />
<br />
=== hackage ===<br />
The hackage bot, when running, provides real-time notifications of new package uploads to [http://hackage.haskell.org Hackage].<br />

<hr />
<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />
[[Image:Irc--haskell-screenshot.png|frame|A screenshot of an irssi session in #haskell]]<br />
<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />
<br />
The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

<hr />
<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

<br />
== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />
[[Image:Irc--haskell-screenshot.png|frame|A screenshot of an irssi session in #haskell]]<br />
<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />
<br />
The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

=== lambdabot ===<br />
<br />
[[Lambdabot]] is both the name of a software package and a bot on the channel. The bot is operated by IRC user int-e and provides many useful services for visitors to the IRC channel. You can interact with it in a private chat or publicly in any channel where it appears (#haskell and a number of others). It is available as a haskell package and can be integrated into ghci. Details on the software are found on a [[Lambdabot|separate wiki page]].<br />
<br />
Here is its interface for the IRC user:<br />
<br />
lambdabot's commands are prepended by a '@' sign.<br />
<br />

== Bots ==<br />
<br />
There are various bots on the channel. Their names and usage are described here.<br />
<br />
=== lambdabot ===<br />
<br />
[[Lambdabot]] is both the name of a software package and a bot on the channel. The bot is operated by int-e and provides many useful services for visitors to the IRC channel. You can interact with it in a private chat or publicly in any channel where it appears (#haskell and a number of others). It is available as a haskell package and can be integrated into ghci. Details on the software are found on a [[Lambdabot|separate wiki page]].<br />
<br />
Here is its interface for the IRC user:<br />
<br />
lambdabot's commands are prepended by a '@' sign.<br />
<br />
{| border="1" cellspacing="0" cellpadding="5"<br />
! Command<br />
! Usage<br />
|-<br />
| @help<br />
| display help to other commands, but help text is not available for all commands.<br />
|-<br />
| @where TOPIC (aliases: @what, @url) <br> @where ? <br> @where+ TOPIC NEWTEXT <br> @where+ TOPIC <br> &nbsp;<br />

|-<br />
| @pointful FUNCTION or '@unpl' FUNCTION<br />
| shows a 'pointful' version of FUNCTION<br />
|-<br />
| @tell <nick> <msg> -- same as @ask<br />
| Next time <nick> speaks in channel they will be notified they have a message pending and how to receive it.<br />
|}<br />
<br />
=== yahb ===<br />
If lambdabot doesn't cut it for you, there is a bot called yahb which runs your request in an actual GHCi prompt, so you can use IO.<br />
<br />
Try e.g. <tt>% readFile "/proc/self/environ"</tt><br />
<br />
=== hackage ===<br />
The hackage bot provides real-time notifications of new package uploads to [http://hackage.haskell.org Hackage].<br />

<hr />
<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />
[[Image:Irc--haskell-screenshot.png|frame|A screenshot of an irssi session in #haskell]]<br />
<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />

The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

== Bots ==<br />
<br />
There are various bots on the channel. Their names and usage are described here.<br />
<br />
=== lambdabot ===<br />
<br />
[[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. You can interact with it on the public channel or in a private chat. It is available as a haskell package and can be integrated into ghci. Details on the software are found on a [[Lambdabot|separate wiki page]].<br />
<br />
Here is its interface for the IRC user:<br />
<br />
lambdabot's commands are prepended by a '@' sign.<br />
<br />
{| border="1" cellspacing="0" cellpadding="5"<br />
! Command<br />
! Usage<br />
|-<br />
| @help<br />
| display help to other commands, but help text is not available for all commands.<br />
|-<br />
| @where TOPIC (aliases: @what, @url) <br> @where ? <br> @where+ TOPIC NEWTEXT <br> @where+ TOPIC <br> &nbsp;<br />

|-<br />
| @run EXPR or '>' EXPR<br />
| evaluates EXPR<br />
|-<br />
| @pl FUNCTION<br />
| shows a [[pointfree]] version of FUNCTION<br />
|-<br />
| @pointful FUNCTION or '@unpl' FUNCTION<br />
| shows a 'pointful' version of FUNCTION<br />
|-<br />
| @tell <nick> <msg> -- same as @ask<br />
| Next time <nick> speaks in channel they will be notified they have a message pending and how to receive it.<br />
|}<br />
<br />
=== yahb ===<br />
If lambdabot doesn't cut it for you, there is a bot called yahb which runs your request in an actual GHCi prompt, so you can use IO.<br />
<br />
Try e.g. <tt>% readFile "/proc/self/environ"</tt><br />
<br />
=== hackage ===<br />
The hackage bot provides real-time notifications of new package uploads to [http://hackage.haskell.org Hackage].<br />

<hr />
<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

<br />
== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />
[[Image:Irc--haskell-screenshot.png|frame|A screenshot of an irssi session in #haskell]]<br />
<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />
<br />
The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

== Bots ==<br />
<br />
There are various bots on the channel. Their names and usage are described here.<br />
<br />
=== lambdabot ===<br />
<br />
[[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 [[Lambdabot|separate wiki page]].<br />
<br />
Here is its interface for the IRC user:<br />
<br />
lambdabot's commands are prepended by a '@' sign.<br />
<br />
{| border="1" cellspacing="0" cellpadding="5"<br />
! Command<br />
! Usage<br />
|-<br />
| @help<br />
| display help to other commands, but help text is not available for all commands.<br />
|-<br />

|}<br />
<br />
=== yahb ===<br />
If lambdabot doesn't cut it for you, there is a bot called yahb which runs your request in an actual GHCi prompt, so you can use IO.<br />
<br />
Try e.g. <tt>% readFile "/proc/self/environ"</tt><br />
<br />
=== hackage ===<br />
The hackage bot provides real-time notifications of new package uploads to [http://hackage.haskell.org Hackage].<br />

<div>Internet Relay Chat is a worldwide text chat service with many thousands<br />
of users among various irc networks.<br />
<br />
The Freenode IRC network hosts the very large #haskell channel, and we've had<br />
up to 1046<br />
concurrent users, making the channel consistently<br />
[https://netsplit.de/channels/details.php?room=%23haskell&net=freenode one of the most popular]<br />
of the thousands of channels on freenode. One famous<br />
resident is [[Lambdabot]], another is [http://hpaste.org hpaste] (see<br />
the [[#Bots|Bots]] section below).<br />
<br />
The IRC channel can be an excellent place to learn more about Haskell,<br />
and to just keep in the loop on new things in the Haskell world. Many<br />
new developments in the Haskell world first appear on the irc channel.<br />
<br />
Since 2009, the Haskell channel has grown large enough that we've split it in two parts:<br />
<br />
* #haskell, for all the usual things<br />
* #haskell-in-depth , for those seeking in depth, or more theoretical discussion<br />
<br />
As always, #haskell remains the primary place for new user questions.<br />

<br />
== Getting there ==<br />
<br />
If you point your irc client to [irc://chat.freenode.net/haskell chat.freenode.net] and then join the #haskell channel, you'll be there. Alternately, you can try http://webchat.freenode.net/ which connects inside the browser.<br />
<br />
Example, using [http://www.irssi.org/ irssi]:<br />
<br />
$ irssi -c chat.freenode.net -n myname -w mypassword<br />
/join #haskell<br />
<br />
Tip, if you're using Emacs to edit your Haskell sources then why not use it to chat about Haskell? Check out [http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient ERC], The Emacs IRC client. Invoke it like this and follow the commands:<br />
<br />
M-x erc-select<br />
...<br />
/join #haskell<br />
<br />
[[Image:Irc--haskell-screenshot.png|frame|A screenshot of an irssi session in #haskell]]<br />
<br />
== Principles ==<br />
<br />
The #haskell channel is a very friendly, welcoming place to hang out,<br />
teach and learn. The goal of #haskell is to encourage learning and<br />
discussion of Haskell, functional programming, and programming in<br />
general. As part of this we welcome newbies, and encourage teaching of<br />
the language.<br />
<br />
Part of the #haskell success comes from the fact that the community<br />
is quite tight knit &mdash; we know each other &mdash; it's not just a homework<br />
channel. As a result, many collaborative projects have arisen between<br />
Haskell irc channel citizens.<br />
<br />
To maintain the friendly, open culture, the following is required:<br />
<br />
* Low to zero tolerance for ridiculing questions. Insulting new users is unacceptable. New Haskell users should feel entirely comfortable asking questions.<br />
<br />
* Helpful answers should be encouraged with <code>name++</code> karma points, in public, as a reward for providing a good answer.<br />
<br />
* Avoid getting frustrated by negative comments and ambiguous questions. Approach them by asking for details (i.e. [http://en.wikipedia.org/wiki/Socratic_method 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.<br />
<br />
== History ==<br />
<br />
The #haskell channel appeared in the late 90s, and really got going<br />
in early 2001, with the help of Shae Erisson (aka shapr).<br />
<br />
== Related channels ==<br />
<br />
In addition to the main Haskell channel there are also:<br />
<br />
=== Language/Country specific ===<br />
<br />
The Freenode staff have asked us to consolidate language channels into the "#haskell-" namespace rather than have them continue on in the "#haskell." namespace. Eventually the language channels below listed with "#haskell." will have to move.<br />

<div>__NOTOC__<br />
<br />
Haskell has a diverse range of use commercially, from aerospace and defense, to finance, to web startups, hardware design firms and a lawnmower manufacturer. This page collects resources on the industrial use of Haskell.<br />
<br />
* The main user conference for industrial Haskell use is CUFP - the [http://cufp.org/ Commercial Users of Functional Programming Workshop].<br />
* The [http://industry.haskell.org Industrial Haskell Group] supports commercial users.<br />
* There is a well-maintained (as of 2018) [https://github.com/erkmos/haskell-companies github repository] that collects information on companies using Haskell.<br />
* [http://commercialhaskell.com/ The commercial Haskell group] is a special interest group for companies and individuals interested in commercial usage of Haskell.<br />
<br />
The Reddit page [https://www.reddit.com/r/haskell/comments/377zyc/72_wouldbe_commercial_haskell_users_what_haskell/ 72 would-be commercial Haskell users: what Haskell success stories we need to see] has several stories of commercial Haskell users.<br />

Aetion was a defense contractor in operation from 1999 to 2011, whose applications use artificial intelligence. Rapidly changing priorities make it important to minimize the code impact of changes, which suits Haskell well. Aetion developed three main projects in<br />
Haskell, all successful. Haskell's concise code was perhaps most important for<br />
rewriting: it made it practicable to throw away old code occasionally. DSELs<br />
allowed the AI to be specified very declaratively. <br />

Developing a modern integrated circuit (ASIC or FPGA) is an enormously<br />
expensive process involving specification, modeling (to choose and fix the<br />
architecture), design (to describe what will become silicon) and verification<br />

silicon (where the cost of a failure can be tens of millions of dollars).<br />
Bluespec, Inc. is a three year-old company that provides language facilities,<br />
methodologies, and tools for this purpose, within the framework of the IEEE<br />
standard languages SystemVerilog and SystemC, but borrowing ideas heavily from<br />
Term Rewriting Systems and functional programming languages like Haskell. In<br />
this talk, after a brief technical overview to set the context, we will<br />
describe our tactics and strategies, and the challenges we face, in introducing<br />
declarative programming ideas into this field, both externally (convincing<br />
customers about the value of these ideas) and internally (using Haskell for our<br />
tool implementation). <br />

LumiGuide is an innovative software company which specialises in smart parking and guidance systems for both bicycles and cars. LumiGuide developed and installed the [https://bicycledutch.wordpress.com/2015/06/09/bicycle-parking-guidance-system-in-utrecht/ P-route Bicycle system] for the City of Utrecht in 2015. This system guides cyclists via digital, street-level displays to available parking space in a number of parking facilities in the city centre. Utrecht is the first city in the world that has a system like this. The detection technology is based on optical sensors which are independent of the bicycle stands. The sensors are mounted to the ceiling in indoor facilities and mounted to poles in outdoor facilities. Every minute, one sensor detects 40 to 60 parking places at the same time in either single- or two-tier bicycle stands as well as (stand-less) free parking places. Bicycles that exceed the maximum parking duration ('orphaned' bicycles) are also detected and the system will automatically keep a log of pictures of the orphaned bicycle which can be used as evidence when the orphaned bicycle is removed by a facility operator. The usage of the facility can be monitored with web-based control software. LumiGuide also develops the indoor and outdoor digital displays which can be controlled using the web-based control software.<br />

;[http://www.cis.upenn.edu/~cis194/spring13/lectures.html Introduction to Haskell (Spring 2013)]: An excellent tutorial to Haskell for beginners given as a course at UPenn by the author of the Typeclassopedia and Diagrams, Brent Yorgey. More compact than LYAH and RWH, but still communicates both basics and some notoriously unfamiliar concepts effectively.<br />
<br />
;[http://learnyouahaskell.com Learn You a Haskell for Great Good! (LYAH)]<br />
: Nicely illustrated tutorial showing Haskell concepts while interacting in GHCi. Written and drawn by Miran Lipovača.<br />
<br />
;[http://book.realworldhaskell.org/ Real World Haskell (RWH)]<br />
: A free online version of the complete book, with numerous reader-submitted comments. RWH is best suited for people who know the fundamentals of Haskell already, and can write basic Haskell programs themselves already. It makes a great follow up after finishing LYAH. It can easily be read cover-to-cover, or you can focus on the chapters that interest you most, or when you find an idea you don't yet understand.<br />

:A Haskell Tutorial, by Jonathan Tang. Most Haskell tutorials on the web seem to take a language-reference-manual approach to teaching. They show you the syntax of the language, a few language constructs, and then have you construct a few simple functions at the interactive prompt. The "hard stuff" of how to write a functioning, useful program is left to the end, or sometimes omitted entirely. This tutorial takes a different tack. You'll start off with command-line arguments and parsing, and progress to writing a fully-functional Scheme interpreter that implements a good-sized subset of R5RS Scheme. Along the way, you'll learn Haskell's I/O, mutable state, dynamic typing, error handling, and parsing features. By the time you finish, you should be fairly fluent in both Haskell and Scheme.<br />

An earlier version of this paper was presented at Functional and Declarative Programming in Education (FDPE02). <br> <strong>Abstract</strong> We argue that teaching purely functional programming as such in freshman courses is detrimental to both the curriculum as well as to promoting the paradigm. Instead, we need to focus on the more general aims of teaching elementary techniques of programming and essential concepts of computing. We support this viewpoint with experience gained during several semesters of teaching large first-year classes (up to 600 students) in Haskell. These classes consisted of computer science students as well as students from other disciplines. We have systematically gathered student feedback by conducting surveys after each semester. This article contributes an approach to the use of modern functional languages in first year courses and, based on this, advocates the use of functional languages in this setting.<br />

:By John Hughes and Magnus Carlsson. Many useful monads can be designed in a systematic way, by successively adding facilities to a trivial monad. The capabilities that can be added in this way include state, exceptions, backtracking, and output. Here we give a brief description of the trivial monad, each kind of extension, and sketches of some interesting operations that each monad supports.<br />

=== Best places to start ===<br />
<br />
;[http://www.cis.upenn.edu/~cis194/spring13/lectures.html Introduction to Haskell (Spring 2013)]: An excellent tutorial to Haskell for beginners given as a course at UPenn by the author of the Typeclassopedia and Diagrams, Brent Yorgey. More compact than LYAH and RWH, but still communicates both basics and some notoriously unfamiliar concepts effectively.<br />
<br />
;[http://learnyouahaskell.com Learn You a Haskell for Great Good! (LYAH)]<br />
: Nicely illustrated tutorial showing Haskell concepts while interacting in GHCi. Written and drawn by Miran Lipovača.<br />
<br />
;[http://book.realworldhaskell.org/ Real World Haskell (RWH)]<br />
: A free online version of the complete book, with numerous reader-submitted comments. RWH is best suited for people who know the fundamentals of Haskell already, and can write basic Haskell programs themselves already. It makes a great follow up after finishing LYAH. It can easily be read cover-to-cover, or you can focus on the chapters that interest you most, or when you find an idea you don't yet understand.<br />
<br />
;[http://en.wikibooks.org/wiki/Haskell/YAHT Yet Another Haskell Tutorial (YAHT)]<br />
:By Hal Daume III et al. A recommended tutorial for Haskell that is still under construction but covers already much ground. Also a classic text.<br />

<br />
;[http://en.wikibooks.org/wiki/Write_Yourself_a_Scheme_in_48_Hours Write Yourself a Scheme in 48 Hours in Haskell]<br />
:A Haskell Tutorial, by Jonathan Tang. Most Haskell tutorials on the web seem to take a language-reference-manual approach to teaching. They show you the syntax of the language, a few language constructs, and then have you construct a few simple functions at the interactive prompt. The "hard stuff" of how to write a functioning, useful program is left to the end, or sometimes omitted entirely. This tutorial takes a different tack. You'll start off with command-line arguments and parsing, and progress to writing a fully-functional Scheme interpreter that implements a good-sized subset of R5RS Scheme. Along the way, you'll learn Haskell's I/O, mutable state, dynamic typing, error handling, and parsing features. By the time you finish, you should be fairly fluent in both Haskell and Scheme.<br />

Journal of Functional Programming 14(1), pp 113-123, 2004. An earlier version of this paper was presented at Functional and Declarative Programming in Education (FDPE02). <br> <strong>Abstract</strong> We argue that teaching purely functional programming as such in freshman courses is detrimental to both the curriculum as well as to promoting the paradigm. Instead, we need to focus on the more general aims of teaching elementary techniques of programming and essential concepts of computing. We support this viewpoint with experience gained during several semesters of teaching large first-year classes (up to 600 students) in Haskell. These classes consisted of computer science students as well as students from other disciplines. We have systematically gathered student feedback by conducting surveys after each semester. This article contributes an approach to the use of modern functional languages in first year courses and, based on this, advocates the use of functional languages in this setting.<br />

<hr />
<div>The canonical time library for Haskell is the [http://hackage.haskell.org/package/time time] package by Ashley Yakeley. There are several similar but different concepts associated with time and the time package keeps these different concepts separated by different data types with appropriate transformations between them to help keep your logic sound. However, if you are trying to use the wrong data type for the wrong task, you may find yourself frustrated with the time library.<br />
<br />
To help avoid frustration, this guide will describe the various data types available in the time library and what temporal concepts they represent. This will help make sure you are using the right data type for the right task. The first few data types in this guide are not widely used in practice, but it is important to understand their associated concepts before moving onto the more complex, widely used, data types. <br />

= Data Types for Measuring Time =<br />
<br />
== AbsoluteTime ==<br />
<br />
<tt>AbsoluteTime</tt> is a data type is type for denoting when an event occurs. AbsoluteTime is a uniform time scale that simply counts the number of seconds since the TAI epoch. There are no leap seconds or timezones. You can compare two <tt>AbsoluteTime</tt>s directly to determine which one came first. You can reference time as far into the future or past as you like to within a resolution of 10<sup>-12</sup> seconds.<br />
<br />
Although <tt>AbsoluteTime</tt> is appropriate for many tasks, it is rarely used in applications and you will likely never use this data type. Unless you are a particularly pioneering person, you will probably want to use <tt>UTCTime</tt> which is more widely used in practice.<br />
<br />
== DiffTime ==<br />
<br />
<tt>DiffTime</tt> is used to represent an absolute duration of time measured in seconds. Subtracting two <tt>AbsoluteTime</tt>s with <tt>diffAbsoluteTime</tt> will produce a <tt>DiffTime</tt> and you can add a <tt>DiffTime</tt> to an <tt>AbsoluteTime</tt> to produce an offset <tt>AbsoluteTime</tt>.<br />
<br />
<tt>DiffTime</tt> is a member of the <tt>Num</tt> and <tt>Fractional</tt>, so can be generated by <tt>fromIntegral</tt> and <tt>realToFrac</tt>. <tt>DiffTime</tt> is also a member of <tt>RealFrac</tt> and <tt>Real</tt> so <tt>round</tt> and <tt>realToFrac</tt> can operate on it.<br />
<br />
<tt>DiffTime</tt> is appropriate in situations where precision time differences are required; however <tt>NominalDiffTime</tt> is more often used in practice.<br />
<br />
== UniversalTime ==<br />
<br />
The problem with <tt>AbsoluteTime</tt> is that Earth's rotation rate is not constant. Over the long term, solar noon would drift over time. <tt>UniversalTime</tt> measures time by counting the number of "solar" rotations, including fractions of a rotation, of the earth since the MJD (Modifed Julian Date) epoch.<br />
<br />
The variations in the Earth's rotation means that a difference in <tt>UniversalTime</tt> does not correspond to any particular amount of time. Your computer's hardware cannot track <tt>UniversalTime</tt> since it can only measure absolute durations. Converting between <tt>UniversalTime</tt> and <tt>AbsoluteTime</tt> would require a database build upon astronomical observations. No such conversion utilities are provided.<br />
<br />
<tt>UniversalTime</tt> is almost never used in practice.<br />
<br />
== UTCTime ==<br />
<br />
<tt>UTCTime</tt> measures "Coordinated Universal Time". One second of <tt>UTCTime</tt> is a constant amount of time equal to one second of <tt>AbsoluteTime</tt>. However, in order to keep "coordinated" with Universal Time, the number of seconds per day varies. Most days have 86400 seconds; however, on occasion a day will have a "leap second", meaning the day will consist of 86399 or 86401 seconds. <tt>UTCTime</tt> counts the number of days (each day consisting of between 86399-86401 seconds) since the MJD epoch plus an absolute time difference up to the number of seconds that occur in that day.<br />
<br />
It is unpredictable which days in the future will have a leap second. A leap second table is needed to convert between <tt>AbsoluteTime</tt> and <tt>UTCTime</tt>. This conversion can only be done reliably within recent history.<br />
<br />
<tt>UTCTime</tt> is the most popular way of referencing events in absolute time. Events occurring hundreds of years ago can be referenced with moderate precision because we may know approximately when during a particular day they occurred, even though we do not know the <tt>AbsoluteTime</tt> that they occurred (because we do not know the detailed historical changes in the rotation rate of the Earth). Events occurring in the recent past can be converted to <tt>AbsoluteTime</tt> with a leap second table. Future events are usually set relative to the day in which they are to occur, so the fact that the absolute time that they will occur at (that is exact the number seconds into the future that they will occur) is unknown is often not a problem.<br />
<br />
The major disadvantage with <tt>UTCTime</tt> is that one cannot compute the absolute difference between two <tt>UTCTime</tt>s without first converting them to <tt>AbsoluteTime</tt>, and that requires an accurate leap second tables. To circumvent this issue, one uses <tt>NominalDiffTime</tt>.<br />
<br />
== NominalDiffTime ==<br />
<br />
The <tt>diffUTCTime</tt> function computes a <tt>NominalDiffTime</tt> between two <tt>UTCTimes</tt> which is the number of seconds that would have occurred between two <tt>UTCTime</tt>s if no leap seconds had occurred between the two events. Therefore the <tt>diffUTCTime</tt> is not suitable for measuring the absolute time between two events to a high degree of precession. However a <tt>NominalDiffTime</tt> is often suitable for advancing an event by a week, a day, or an hour, since one would normally want said event to occur at the same time of day, or same minute of the hour, regardless of whether or not a leap second happens to be inserted in that duration.<br />
<br />
<tt>NominalDiffTime</tt> is a member of the <tt>Num</tt> and <tt>Fractional</tt>, so can be generated by <tt>fromIntegral</tt> and <tt>realToFrac</tt>. <tt>NominalDiffTime</tt> is also a member of <tt>RealFrac</tt> and <tt>Real</tt> so <tt>round</tt> and <tt>realToFrac</tt> can operate on it.<br />
<br />
<tt>NominialDiffTime</tt> is regularly used. In fact, <tt>POSIXTime</tt> is the <tt>NominalDiffTime</tt> since the UNIX epoch of Jan 1st, 1970, UTC.<br />
<br />
= Data Types for Denoting Time =<br />
<br />
So far our data have denoted occurrences of events by counting the number of days, or the number of seconds since some fixed reference epoch. However we usually tell time by using years, months, day of month, hours, minutes and seconds. The remain data types will assist with this more usual approach to telling time.<br />
<br />
== Day ==<br />
<br />
The <tt>Day</tt> data type is an abstract way of referring to a calender date. Due to time zone issues, the <tt>Day</tt> type does not necessarily refer to any specific 1-day long absolute time period.<br />
<br />
The standard calender used to reference a date is the Gregorian calendar. The <tt>toGregorian</tt> and <tt>fromGregorian</tt> functions will construct and deconstruct a <tt>Day</tt> from the usual year-month-day format. There are other calendars, such as the Julian calendar, which are only used in unusual situations.<br />
<br />
== TimeOfDay ==<br />
<br />
<tt>TimeOfDay</tt> represents "wall-clock" time. It consists of an hour of the day, a minute of the hour, and a second of the minute, including fractions of a second up to a precession of 10-12. The seconds could go up to 61 in order to accommodate leap seconds.<br />
<br />
== LocalTime ==<br />
<br />
A <tt>Day</tt> with a <tt>TimeOfDay</tt> forms a <tt>LocalTime</tt>. This is contains the data that we normally denote time with: a year, month, day, hour, minute, and second. However, it does not denote an absolute time because it contains no time zone information.<br />
<br />
<tt>LocalTime</tt> is used represent date and time for printing and parsing; however it should be avoided for computation. The biggest problem with <tt>LocalTime</tt> is that, due to daylight savings time, regularly the same time of day is repeated twice a day. This means you cannot even use <tt>LocalTime</tt>s to reliably determine the relative order of events.<br />
<br />
== TimeZone ==<br />
<br />
Somewhat confusingly named, a <tt>TimeZone</tt> represents an offset from UTC measured in minutes. It also contains ancillary data such as the timezone name and whether or not it is intended to be used for summer time only. Eastern Standard Time (EST) or Pacific Daylight Time (PDT) are examples of timezone that could be represented by a <tt>TimeZone</tt> value. <br />
<br />
It does not represent the time zone of a region, such as Eastern Time, because regions often vary their offsets from UTC depending on the time of year.<br />
<br />
The <tt>utc</tt> value is the value of the <tt>TimeZone</tt> with no offset from UTC.<br />
<br />
== ZonedTime == <br />
<br />
A <tt>ZonedTime</tt> is a <tt>LocalTime</tt> together with a <tt>TimeZone</tt>. This does refer to a specific event in absolute time and can be converted to a <tt>UTCTime</tt> with the <tt>zoneTimeToUTC</tt> function, and could be further converted into a <tt>AbsoluteTime</tt> if one has a leap second table.<br />
<br />
There are, of course, many different <tt>ZonedTime</tt> values corresponding to the same absolute, <tt>UTCTime</tt>. Given a <tt>TimeZone</tt> one can create a <tt>ZonedTime</tt> with that <tt>TimeZone</tt> by using the <tt>utcToZonedTime</tt> function.<br />
<br />
<tt>ZonedTime</tt> is a common stop when converting between common year-month-day-hour-minute-second human time format and absolute <tt>UTCTime</tt> time.<br />
<br />
== TimeZoneSeries ==<br />
<br />
Almost nothing in the time library deals with regional time zones such as "Eastern Time" or "Pacific time" For that we need to reach out to the timezone-series and timezone-olson packages. The difficulty with regional time zones is, like leap seconds, that they are unpredictable and subject to be changed. <br />
<br />
A <tt>TimeZoneSeries</tt> is a series of <tt>TimeZone</tt>s, that is offsets from UTC, along with the absolute times where those <tt>TimeZone</tt>s are in effect. This is a suitable structure for defining a regional time zone. The functions in the timezone-olson package will allow you to create a <tt>TimeZoneSeries</tt> from an Olson time zone database file.<br />
<br />
== getTimeZone ==<br />
<br />
There there is one set of functions in the time package that does deal with regional time zones. The <tt>getTimeZone</tt> function will compute the timezone for a given, <tt>UTCTime</tt>, but only the local region as set by the <tt>TZ</tt> environment variable. The <tt>getCurrentTimeZone</tt>, <tt>getZonedTime</tt>, and <tt>utcToLocalZonedTime</tt> are functions derived from <tt>getTimeZone</tt>.<br />
<br />
There is no functionality in the time package that will convert from a local regional time to <tt>UTCTime</tt>, owing to the fact that the same local regional time may refer to multiple different <tt>UTCTime</tt> due to daylight savings times. <tt>localTimeToUTC'</tt> from the <tt>timezone-series</tt> packages will do this conversion given a <tt>TimeZoneSeries</tt>.</div>SimonMichaelhttps://wiki.haskell.org/index.php?title=Time&diff=63143Time2019-11-21T19:29:45Z<p>SimonMichael: move the intro text & cheatsheet out from the subheading, note cheatsheet author</p>

The first few data types in this guide are not widely used in practice, but it is important to understand their associated concepts before moving onto the more complex, widely used, data types. <br />

= Data Types for Measuring Time =<br />
<br />
== AbsoluteTime ==<br />
<br />
<tt>AbsoluteTime</tt> is a data type is type for denoting when an event occurs. AbsoluteTime is a uniform time scale that simply counts the number of seconds since the TAI epoch. There are no leap seconds or timezones. You can compare two <tt>AbsoluteTime</tt>s directly to determine which one came first. You can reference time as far into the future or past as you like to within a resolution of 10<sup>-12</sup> seconds.<br />
<br />
Although <tt>AbsoluteTime</tt> is appropriate for many tasks, it is rarely used in applications and you will likely never use this data type. Unless you are a particularly pioneering person, you will probably want to use <tt>UTCTime</tt> which is more widely used in practice.<br />
<br />
== DiffTime ==<br />
<br />
<tt>DiffTime</tt> is used to represent an absolute duration of time measured in seconds. Subtracting two <tt>AbsoluteTime</tt>s with <tt>diffAbsoluteTime</tt> will produce a <tt>DiffTime</tt> and you can add a <tt>DiffTime</tt> to an <tt>AbsoluteTime</tt> to produce an offset <tt>AbsoluteTime</tt>.<br />
<br />
<tt>DiffTime</tt> is a member of the <tt>Num</tt> and <tt>Fractional</tt>, so can be generated by <tt>fromIntegral</tt> and <tt>realToFrac</tt>. <tt>DiffTime</tt> is also a member of <tt>RealFrac</tt> and <tt>Real</tt> so <tt>round</tt> and <tt>realToFrac</tt> can operate on it.<br />
<br />
<tt>DiffTime</tt> is appropriate in situations where precision time differences are required; however <tt>NominalDiffTime</tt> is more often used in practice.<br />
<br />
== UniversalTime ==<br />
<br />
The problem with <tt>AbsoluteTime</tt> is that Earth's rotation rate is not constant. Over the long term, solar noon would drift over time. <tt>UniversalTime</tt> measures time by counting the number of "solar" rotations, including fractions of a rotation, of the earth since the MJD (Modifed Julian Date) epoch.<br />
<br />
The variations in the Earth's rotation means that a difference in <tt>UniversalTime</tt> does not correspond to any particular amount of time. Your computer's hardware cannot track <tt>UniversalTime</tt> since it can only measure absolute durations. Converting between <tt>UniversalTime</tt> and <tt>AbsoluteTime</tt> would require a database build upon astronomical observations. No such conversion utilities are provided.<br />
<br />
<tt>UniversalTime</tt> is almost never used in practice.<br />
<br />
== UTCTime ==<br />
<br />
<tt>UTCTime</tt> measures "Coordinated Universal Time". One second of <tt>UTCTime</tt> is a constant amount of time equal to one second of <tt>AbsoluteTime</tt>. However, in order to keep "coordinated" with Universal Time, the number of seconds per day varies. Most days have 86400 seconds; however, on occasion a day will have a "leap second", meaning the day will consist of 86399 or 86401 seconds. <tt>UTCTime</tt> counts the number of days (each day consisting of between 86399-86401 seconds) since the MJD epoch plus an absolute time difference up to the number of seconds that occur in that day.<br />
<br />
It is unpredictable which days in the future will have a leap second. A leap second table is needed to convert between <tt>AbsoluteTime</tt> and <tt>UTCTime</tt>. This conversion can only be done reliably within recent history.<br />
<br />
<tt>UTCTime</tt> is the most popular way of referencing events in absolute time. Events occurring hundreds of years ago can be referenced with moderate precision because we may know approximately when during a particular day they occurred, even though we do not know the <tt>AbsoluteTime</tt> that they occurred (because we do not know the detailed historical changes in the rotation rate of the Earth). Events occurring in the recent past can be converted to <tt>AbsoluteTime</tt> with a leap second table. Future events are usually set relative to the day in which they are to occur, so the fact that the absolute time that they will occur at (that is exact the number seconds into the future that they will occur) is unknown is often not a problem.<br />
<br />
The major disadvantage with <tt>UTCTime</tt> is that one cannot compute the absolute difference between two <tt>UTCTime</tt>s without first converting them to <tt>AbsoluteTime</tt>, and that requires an accurate leap second tables. To circumvent this issue, one uses <tt>NominalDiffTime</tt>.<br />
<br />
== NominalDiffTime ==<br />
<br />
The <tt>diffUTCTime</tt> function computes a <tt>NominalDiffTime</tt> between two <tt>UTCTimes</tt> which is the number of seconds that would have occurred between two <tt>UTCTime</tt>s if no leap seconds had occurred between the two events. Therefore the <tt>diffUTCTime</tt> is not suitable for measuring the absolute time between two events to a high degree of precession. However a <tt>NominalDiffTime</tt> is often suitable for advancing an event by a week, a day, or an hour, since one would normally want said event to occur at the same time of day, or same minute of the hour, regardless of whether or not a leap second happens to be inserted in that duration.<br />
<br />
<tt>NominalDiffTime</tt> is a member of the <tt>Num</tt> and <tt>Fractional</tt>, so can be generated by <tt>fromIntegral</tt> and <tt>realToFrac</tt>. <tt>NominalDiffTime</tt> is also a member of <tt>RealFrac</tt> and <tt>Real</tt> so <tt>round</tt> and <tt>realToFrac</tt> can operate on it.<br />
<br />
<tt>NominialDiffTime</tt> is regularly used. In fact, <tt>POSIXTime</tt> is the <tt>NominalDiffTime</tt> since the UNIX epoch of Jan 1st, 1970, UTC.<br />
<br />
= Data Types for Denoting Time =<br />
<br />
So far our data have denoted occurrences of events by counting the number of days, or the number of seconds since some fixed reference epoch. However we usually tell time by using years, months, day of month, hours, minutes and seconds. The remain data types will assist with this more usual approach to telling time.<br />
<br />
== Day ==<br />
<br />
The <tt>Day</tt> data type is an abstract way of referring to a calender date. Due to time zone issues, the <tt>Day</tt> type does not necessarily refer to any specific 1-day long absolute time period.<br />
<br />
The standard calender used to reference a date is the Gregorian calendar. The <tt>toGregorian</tt> and <tt>fromGregorian</tt> functions will construct and deconstruct a <tt>Day</tt> from the usual year-month-day format. There are other calendars, such as the Julian calendar, which are only used in unusual situations.<br />
<br />
== TimeOfDay ==<br />
<br />
<tt>TimeOfDay</tt> represents "wall-clock" time. It consists of an hour of the day, a minute of the hour, and a second of the minute, including fractions of a second up to a precession of 10-12. The seconds could go up to 61 in order to accommodate leap seconds.<br />
<br />
== LocalTime ==<br />
<br />
A <tt>Day</tt> with a <tt>TimeOfDay</tt> forms a <tt>LocalTime</tt>. This is contains the data that we normally denote time with: a year, month, day, hour, minute, and second. However, it does not denote an absolute time because it contains no time zone information.<br />
<br />
<tt>LocalTime</tt> is used represent date and time for printing and parsing; however it should be avoided for computation. The biggest problem with <tt>LocalTime</tt> is that, due to daylight savings time, regularly the same time of day is repeated twice a day. This means you cannot even use <tt>LocalTime</tt>s to reliably determine the relative order of events.<br />
<br />
== TimeZone ==<br />
<br />
Somewhat confusingly named, a <tt>TimeZone</tt> represents an offset from UTC measured in minutes. It also contains ancillary data such as the timezone name and whether or not it is intended to be used for summer time only. Eastern Standard Time (EST) or Pacific Daylight Time (PDT) are examples of timezone that could be represented by a <tt>TimeZone</tt> value. <br />
<br />
It does not represent the time zone of a region, such as Eastern Time, because regions often vary their offsets from UTC depending on the time of year.<br />
<br />
The <tt>utc</tt> value is the value of the <tt>TimeZone</tt> with no offset from UTC.<br />
<br />
== ZonedTime == <br />
<br />
A <tt>ZonedTime</tt> is a <tt>LocalTime</tt> together with a <tt>TimeZone</tt>. This does refer to a specific event in absolute time and can be converted to a <tt>UTCTime</tt> with the <tt>zoneTimeToUTC</tt> function, and could be further converted into a <tt>AbsoluteTime</tt> if one has a leap second table.<br />
<br />
There are, of course, many different <tt>ZonedTime</tt> values corresponding to the same absolute, <tt>UTCTime</tt>. Given a <tt>TimeZone</tt> one can create a <tt>ZonedTime</tt> with that <tt>TimeZone</tt> by using the <tt>utcToZonedTime</tt> function.<br />
<br />
<tt>ZonedTime</tt> is a common stop when converting between common year-month-day-hour-minute-second human time format and absolute <tt>UTCTime</tt> time.<br />
<br />
== TimeZoneSeries ==<br />
<br />
Almost nothing in the time library deals with regional time zones such as "Eastern Time" or "Pacific time" For that we need to reach out to the timezone-series and timezone-olson packages. The difficulty with regional time zones is, like leap seconds, that they are unpredictable and subject to be changed. <br />
<br />
A <tt>TimeZoneSeries</tt> is a series of <tt>TimeZone</tt>s, that is offsets from UTC, along with the absolute times where those <tt>TimeZone</tt>s are in effect. This is a suitable structure for defining a regional time zone. The functions in the timezone-olson package will allow you to create a <tt>TimeZoneSeries</tt> from an Olson time zone database file.<br />
<br />
== getTimeZone ==<br />
<br />
There there is one set of functions in the time package that does deal with regional time zones. The <tt>getTimeZone</tt> function will compute the timezone for a given, <tt>UTCTime</tt>, but only the local region as set by the <tt>TZ</tt> environment variable. The <tt>getCurrentTimeZone</tt>, <tt>getZonedTime</tt>, and <tt>utcToLocalZonedTime</tt> are functions derived from <tt>getTimeZone</tt>.<br />
<br />
There is no functionality in the time package that will convert from a local regional time to <tt>UTCTime</tt>, owing to the fact that the same local regional time may refer to multiple different <tt>UTCTime</tt> due to daylight savings times. <tt>localTimeToUTC'</tt> from the <tt>timezone-series</tt> packages will do this conversion given a <tt>TimeZoneSeries</tt>.</div>SimonMichaelhttps://wiki.haskell.org/index.php?title=Time&diff=63141Time2019-11-21T19:03:02Z<p>SimonMichael: move image after intro text</p>

<div>= Data Types for Measuring Time =<br />
<br />
The canonical time library for Haskell is the time package by Ashley Yakeley. There are several similar but different concepts associated with time and the time package keeps these different concepts separated by different data types with appropriate transformations between them to help keep your logic sound. However, if you are trying to use the wrong data type for the wrong task, you may find yourself frustrated with the time library.<br />
<br />
To help avoid frustration, this guide will describe the various data types available in the time library and what temporal concepts they represent. This will help make sure you are using the right data type for the right task. The first few data types in this guide are not widely used in practice, but it is important to understand their associated concepts before moving onto the more complex, widely used, data types. <br />

<br />

<br />
Frag is a 3D first person shooting game written in Haskell, by Mun Hon<br />
Cheong. It is licensed under the GPL. The design and implementation of<br />
Frag is described in Mun's 2005 undergraduate thesis, <br />
[http://www.cse.unsw.edu.au/~pls/thesis/munc-thesis.pdf Functional Programming and 3D Games]. An AI system for Frag is described in Jayatheeban Soundararajan's 2007 undergrad thesis, [http://www.cse.unsw.edu.au/~pls/thesis/theeban-thesis.pdf Functional Programming and 3D<br />
Games].<br />
<br />
[http://uk.youtube.com/watch?v=0jYdu2u8gAU YouTube Video]<br />
<br />
== Features ==<br />
<br />
* Yampa, a domain-specific embedded language for the programming of hybrid systems that using the concepts of Functional Reactive Programming (FRP) was used to program the game entities.<br />
* The Quake 3 BSP level format, Q3Map2, and the MD3 format for models and animations are used in this game.<br />
* Sven Panne's OpenGL binding, HOpenGL is used to render graphics.<br />
<br />
== Requirements ==<br />
<br />
* GHC 6.8 or greater, providing HOpenGL-2.0.<br />
* OpenGL drivers that support the vertex array and multitexture OpenGL extensions<br />
* Frag has portability problems. It is known to work on i386 and AMD64, and known not to work on big-endian systems.<br />
<br />
See the blog article [http://monadickid.blogspot.com/2008/11/haskell-eye-for-windows-guy.html A Haskell eye for the windows guy] for the list of requirements and how to install for Windows users.<br />
<br />
== Download ==<br />
<br />
The code can be downloaded from<br />
[http://hackage.haskell.org/cgi-bin/hackage-scripts/package/frag Hackage]; it is also distributed via a Darcs repository: <br />
