/* This file is a compatability layer.  It allows the usage of flexible box 
model layouts accross multiple browsers, including older browsers.  The newest,
universal implementation of the flexible box model is used when available (see
`Modern browsers` comments below).  Browsers that are known to implement this 
new spec completely include:

    Firefox 28.0+

<p>A Haskell module is a collection of related functions, types and
typeclasses. A Haskell program is a collection of modules where the main
module loads up the other modules and then uses the functions defined in
them to do something. Having code split up into several modules has
quite a lot of advantages. If a module is generic enough, the functions
it exports can be used in a multitude of different programs. If your own
code is separated into self-contained modules which don't rely on each
other too much (we also say they are loosely coupled), you can reuse
them later on. It makes the whole deal of writing code more manageable
by having it split into several parts, each of which has some sort of
purpose.</p>
<p>The Haskell standard library is split into modules, each of them
contains functions and types that are somehow related and serve some
common purpose. There's a module for manipulating lists, a module for
concurrent programming, a module for dealing with complex numbers, etc.
All the functions, types and typeclasses that we've dealt with so far
were part of the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> module, which is imported by default. In this
chapter, we're going to examine a few useful modules and the functions
that they have. But first, we're going to see how to import modules.</p>

<p>The syntax for importing modules in a Haskell script is
<code>import &lt;module name&gt;</code>.
This must be done before defining any functions, so imports are
usually done at the top of the file. One script can, of course, import
several modules. Just put each import statement into a separate line.
Let's import the <code>Data.List</code> module, which has a bunch of useful functions
for working with lists and use a function that it exports to create a
function that tells us how many unique elements a list has.</p>

<p>When you do <code>import Data.List</code>, all the functions that <code>Data.List</code> exports
become available in the global namespace, meaning that you can call them
from wherever in the script. <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a> is a function defined in <code>Data.List</code> that
takes a list and weeds out duplicate elements. Composing <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:length"><code>length</code></a> and <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a>
by doing <code>length . nub</code> produces a function that's the equivalent of 
<code>\xs -&gt; length (nub xs)</code>.</p>
<p>You can also put the functions of modules into the global namespace when
using IHaskell or GHCI. If you're in IHaskell or GHCI and you want to be able to call the
functions exported by <code>Data.List</code>, do this:</p>

<p>However, if you've loaded a script that already imports a module, you

<p>If you just need a couple of functions from a module, you can

<a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a> and <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:sort"><code>sort</code></a> functions from <code>Data.List</code>, we'd do this:</p>

<p>You can also choose to import all of the functions of a module except a
few select ones. That's often useful when several modules export
functions with the same name and you want to get rid of the offending
ones. Say we already have our own function that's called <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a> and we want
to import all the functions from <code>Data.List</code> except the <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a> function:</p>

<p>Another way of dealing with name clashes is to do qualified imports. The
<code>Data.Map</code> module, which offers a data structure for looking up values by
key, exports a bunch of functions with the same name as <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a>
functions, like <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a> or <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:null"><code>null</code></a>. So when we import <code>Data.Map</code> and then call
<a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a>, Haskell won't know which function to use. Here's how we solve
this:</p>

</div>
</div>
</div>
<div class="cell border-box-sizing code_cell rendered">
<div class="input">
<div class="prompt input_prompt">In&nbsp;[5]:</div>
<div class="inner_cell">
    <div class="input_area">
<div class=" highlight hl-Haskell"><pre><span></span><span class="kr">import</span> <span class="k">qualified</span> <span class="nn">Data.Map</span>
</pre></div>

    </div>

</div>
<div class="cell border-box-sizing text_cell rendered"><div class="prompt input_prompt">
</div><div class="inner_cell">
<div class="text_cell_render border-box-sizing rendered_html">
<p>This makes it so that if we want to reference <code>Data.Map</code>'s <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a>
function, we have to do <code>Data.Map.filter</code>, whereas just <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a> still
refers to the normal <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a> we all know and love. But typing out
<code>Data.Map</code> in front of every function from that module is kind of tedious.
That's why we can rename the qualified import to something shorter:</p>

</div>
</div>
</div>
<div class="cell border-box-sizing code_cell rendered">
<div class="input">
<div class="prompt input_prompt">In&nbsp;[6]:</div>

</div>
<div class="cell border-box-sizing text_cell rendered"><div class="prompt input_prompt">
</div><div class="inner_cell">
<div class="text_cell_render border-box-sizing rendered_html">
<p>Now, to reference <code>Data.Map</code>'s <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a> function, we just use <code>M.filter</code>.</p>
<p>Use <a href="http:https://www.haskell.org/ghc/docs/latest/html/libraries/">this handy
reference</a> to
see which modules are in the standard library. A great way to pick up
new Haskell knowledge is to just click through the standard library
reference and explore the modules and their functions. You can also view
the Haskell source code for each module. Reading the source code of some
modules is a really good way to learn Haskell and get a solid feel for
it.</p>
<p>To search for functions or to find out where they're located, use
<a href="http:https://haskell.org/hoogle">Hoogle</a>. It's a really awesome Haskell
search engine, you can search by name, module name or even type
signature.</p>

<h2 id="Data.List">Data.List<a class="anchor-link" href="#Data.List">&#182;</a></h2><p>The <code>Data.List</code> module is all about lists, obviously. It provides some
very useful functions for dealing with them. We've already met some of
its functions (like <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:map"><code>map</code></a> and <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:filter"><code>filter</code></a>) because the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> module exports
some functions from <code>Data.List</code> for convenience. You don't have to import
<code>Data.List</code> via a qualified import because it doesn't clash with any
<a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> names except for those that <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> already steals from
<code>Data.List</code>. Let's take a look at some of the functions that we haven't
met before.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:intersperse"><code>intersperse</code></a></strong> takes an element and a list and then puts that element in
between each pair of elements in the list. Here's a demonstration:</p>

<p><strong><code>foldl'</code></strong> and <strong><code>foldl1'</code></strong> are stricter versions of their respective lazy
incarnations. When using lazy folds on really big lists, you might often
get a stack overflow error. The culprit for that is that due to the lazy
nature of the folds, the accumulator value isn't actually updated as the
folding happens. What actually happens is that the accumulator kind of
makes a promise that it will compute its value when asked to actually
produce the result (also called a thunk). That happens for every
intermediate accumulator and all those thunks overflow your stack. The
strict folds aren't lazy buggers and actually compute the intermediate
values as they go along instead of filling up your stack with thunks. So
if you ever get stack overflow errors when doing lazy folds, try
switching to their strict versions.</p>

<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:find"><code>find</code></a></strong> takes a list and a predicate and returns the first element that

value. We'll be covering algebraic data types more in depth in the next
chapter but for now, this is what you need to know: a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Maybe"><code>Maybe</code></a> value can
either be <code>Just something</code> or <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:Nothing"><code>Nothing</code></a>. Much like a list can be either an
empty list or a list with some elements, a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Maybe"><code>Maybe</code></a> value can be either no
elements or a single element. And like the type of a list of, say,
integers is <code>[Int]</code>, the type of maybe having an integer is <code>Maybe Int</code>.
Anyway, let's take our <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:find"><code>find</code></a> function for a spin.</p>

<p>Notice the type of <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:find"><code>find</code></a>. Its result is <code>Maybe a</code>. That's kind of like
having the type of <code>[a]</code>, only a value of the type <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Maybe"><code>Maybe</code></a> can contain
either no elements or one element, whereas a list can contain no
elements, one element or several elements.</p>
<p>Remember when we were searching for the first time our stock went over
\$1000. We did `head (dropWhile (\(val,y,m,d) -&gt; val &lt; 1000) stock)`.
Remember that [`head`](https://hackage.haskell.org/package/base/docs/Prelude.html#v:head) is not really safe. What would happen if our stock
never went over \$1000? Our application of <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:dropWhile"><code>dropWhile</code></a> would return an
empty list and getting the head of an empty list would result in an
error. However, if we rewrote that as
<code>find (\(val,y,m,d) -&gt; val &gt; 1000)</code>
stock, we'd be much safer. If our stock never went over \$1000 (so
if no element satisfied the predicate), we'd get back a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:Nothing"><code>Nothing</code></a>. But
there was a valid answer in that list, we'd get, say,
<code>Just (1001.4,2008,9,4)</code>.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:elemIndex"><code>elemIndex</code></a></strong> is kind of like <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:elem"><code>elem</code></a>, only it doesn't return a boolean value.
It maybe returns the index of the element we're looking for. If that
element isn't in our list, it returns a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:Nothing"><code>Nothing</code></a>.</p>

<p>We already covered <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:zip"><code>zip</code></a> and <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:zipWith"><code>zipWith</code></a>. We noted that they zip together two
lists, either in a tuple or with a binary function (meaning such a
function that takes two parameters). But what if we want to zip together
three lists? Or zip three lists with a function that takes three
parameters? Well, for that, we have <strong><code>zip3</code></strong>, <strong><code>zip4</code></strong>, etc. and <strong><code>zipWith3</code></strong>,
<strong><code>zipWith4</code></strong>, etc. These variants go up to 7. While this may look like a
hack, it works out pretty fine, because there aren't many times when you
want to zip 8 lists together. There's also a very clever way for zipping
infinite numbers of lists, but we're not advanced enough to cover that
just yet.</p>

The function does have a kind of strange name. It turns out that "nub"

should use real words for function names instead of old-people words.</p>

that they take an <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Int"><code>Int</code></a> as one of their parameters (or return an <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Int"><code>Int</code></a>),
even though they could be more generic and usable if they just took any
type that's part of the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Integral"><code>Integral</code></a> or <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Num"><code>Num</code></a> typeclasses (depending on the
functions). They do that for historical reasons. However, fixing that
would probably break a lot of existing code. That's why <code>Data.List</code> has
their more generic equivalents, named <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericLength"><code>genericLength</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericTake"><code>genericTake</code></a></strong>,
<strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericDrop"><code>genericDrop</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericSplitAt"><code>genericSplitAt</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericIndex"><code>genericIndex</code></a></strong> and <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericReplicate"><code>genericReplicate</code></a></strong>. For
instance, <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:length"><code>length</code></a> has a type signature of <code>length :: [a] -&gt; Int</code>. If we
try to get the average of a list of numbers by doing
<code>let xs = [1..6] in sum xs / length xs</code>,
we get a type error, because you can't use <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:-47-"><code>/</code></a> with an <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Int"><code>Int</code></a>.
<a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:genericLength"><code>genericLength</code></a>, on the other hand, has a type signature of
<code>genericLength :: (Num a) =&gt; [b] -&gt; a</code>. Because a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Num"><code>Num</code></a> can act like a
floating point number, getting the average by doing
<code>let xs = [1..6] in sum xs / genericLength xs</code> works out just fine.</p>
<p>The <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a>, <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:delete"><code>delete</code></a>, <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:union"><code>union</code></a>, <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:intersect"><code>intersect</code></a> and <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:group"><code>group</code></a> functions all have their
more general counterparts called <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nubBy"><code>nubBy</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:deleteBy"><code>deleteBy</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:unionBy"><code>unionBy</code></a></strong>, <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:intersectBy"><code>intersectBy</code></a></strong>
and <strong><a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:groupBy"><code>groupBy</code></a></strong>. The difference between them is that the first set of
functions use <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:-61--61-"><code>==</code></a> to test for equality, whereas the <em>By</em> ones also take
an equality function and then compare them by using that equality
function. <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:group"><code>group</code></a> is the same as <code>groupBy (==)</code>.</p>
<p>For instance, say we have a list that describes the value of a function
for every second. We want to segment it into sublists based on when the
value was below zero and when it went above. If we just did a normal
<a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:group"><code>group</code></a>, it would just group the equal adjacent values together. But what
we want is to group them by whether they are negative or not. That's
where <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:groupBy"><code>groupBy</code></a> comes in! The equality function supplied to the <em>By</em>
functions should take two elements of the same type and return <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:True"><code>True</code></a> if
it considers them equal by its standards.</p>

<p>From this, we clearly see which sections are positive and which are
negative. The equality function supplied takes two elements and then
returns <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:True"><code>True</code></a> only if they're both negative or if they're both positive.
This equality function can also be written as
<code>\x y -&gt; (x &gt; 0) &amp;&amp; (y &gt; 0) || (x &lt;= 0) &amp;&amp; (y &lt;= 0)</code>, although I think the first way is more

<p>Lists can be compared, but when they are, they are compared

<p>Awesome! <code>compare `on` length</code> ... man, that reads almost like real
English! If you're not sure how exactly the <a href="https://hackage.haskell.org/package/base/docs/Data-Function.html#v:on"><code>on</code></a> works here,
<code>compare `on` length</code> is the equivalent of
<code>\x y -&gt; length x `compare` length y</code>.
When you're dealing with <em>By</em> functions that take an equality
function, you usually do <code>(==) `on` something</code> and when you're dealing
with <em>By</em> functions that take an ordering function, you usually do
<code>compare `on` something</code>.</p>

<p>The <code>Data.Char</code> module does what its name suggests. It exports functions
that deal with characters. It's also helpful when filtering and mapping
over strings because they're just lists of characters.</p>
<p><code>Data.Char</code> exports a bunch of predicates over characters. That is,
functions that take a character and tell us whether some assumption
about it is true or false. Here's what they are:</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isControl"><code>isControl</code></a></strong> checks whether a character is a control character.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isSpace"><code>isSpace</code></a></strong> checks whether a character is a white-space characters. That
includes spaces, tab characters, newlines, etc.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isLower"><code>isLower</code></a></strong> checks whether a character is lower-cased.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isUpper"><code>isUpper</code></a></strong> checks whether a character is upper-cased.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isAlpha"><code>isAlpha</code></a></strong> checks whether a character is a letter.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isAlphaNum"><code>isAlphaNum</code></a></strong> checks whether a character is a letter or a number.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isPrint"><code>isPrint</code></a></strong> checks whether a character is printable. Control characters, for
instance, are not printable.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isDigit"><code>isDigit</code></a></strong> checks whether a character is a digit.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isOctDigit"><code>isOctDigit</code></a></strong> checks whether a character is an octal digit.</p>

<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isLetter"><code>isLetter</code></a></strong> checks whether a character is a letter.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isMark"><code>isMark</code></a></strong> checks for Unicode mark characters. Those are characters that
combine with preceding letters to form letters with accents. Use this if
you are French.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:isNumber"><code>isNumber</code></a></strong> checks whether a character is numeric.</p>

<p>All these predicates have a type signature of <code>Char -&gt; Bool</code>. Most of the
time you'll use this to filter out strings or something like that. For
instance, let's say we're making a program that takes a username and the
username can only be comprised of alphanumeric characters. We can use
the <code>Data.List</code> function <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:all"><code>all</code></a> in combination with the <code>Data.Char</code> predicates
to determine if the username is alright.</p>

<p>Ah.</p>
<p>The <code>Data.Char</code> also exports a datatype that's kind of like <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Ordering"><code>Ordering</code></a>. The
<a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Ordering"><code>Ordering</code></a> type can have a value of <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:LT"><code>LT</code></a>, <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:EQ"><code>EQ</code></a> or <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:GT"><code>GT</code></a>. It's a sort of
enumeration. It describes a few possible results that can arise from
comparing two elements. The <a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#t:GeneralCategory"><code>GeneralCategory</code></a> type is also an enumeration.
It presents us with a few possible categories that a character can fall
into. The main function for getting the general category of a character
is <a href="https://hackage.haskell.org/package/base/docs/Data-Char.html#v:generalCategory"><code>generalCategory</code></a>. It has a type of
<code>generalCategory :: Char -&gt; GeneralCategory</code>.
There are about 31 categories so we won't list them all
here, but let's play around with the function.</p>

<h2 id="Data.Map">Data.Map<a class="anchor-link" href="#Data.Map">&#182;</a></h2><p>Association lists (also called dictionaries) are lists that are used to
store key-value pairs where ordering doesn't matter. For instance, we
might use an association list to store phone numbers, where phone
numbers would be the values and people's names would be the keys. We
don't care in which order they're stored, we just want to get the right
phone number for the right person.</p>
<p>The most obvious way to represent association lists in Haskell would be
by having a list of pairs. The first component in the pair would be the
key, the second component the value. Here's an example of an association
list with phone numbers:</p>

<p>Pretty simple. The function that takes a key and a list, filters the
list so that only matching keys remain, gets the first key-value that
matches and returns the value. But what happens if the key we're looking
for isn't in the association list? Hmm. Here, if a key isn't in the
association list, we'll end up trying to get the head of an empty list,
which throws a runtime error. However, we should avoid making our
programs so easy to crash, so let's use the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Maybe"><code>Maybe</code></a> data type. If we don't
find the key, we'll return a <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:Nothing"><code>Nothing</code></a>. If we find it, we'll return
<code>Just something</code>, where something is the value corresponding to that key.</p>

<p>Look at the type declaration. It takes a key that can be equated, an
association list and then it maybe produces a value. Sounds about right.</p>
<p>This is a textbook recursive function that operates on a list. Edge
case, splitting a list into a head and a tail, recursive calls, they're

<p>Works like a charm! If we have the girl's phone number, we <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:Just"><code>Just</code></a> get the

<p>We just implemented the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:lookup"><code>lookup</code></a> function from <code>Data.List</code>. If we want to
find the corresponding value to a key, we have to traverse all the
elements of the list until we find it. The <code>Data.Map</code> module offers
association lists that are much faster (because they're internally
implemented with trees) and also it provides a lot of utility functions.
From now on, we'll say we're working with maps instead of association
lists.</p>
<p>Because <code>Data.Map</code> exports functions that clash with the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> and
<code>Data.List</code> ones, we'll do a qualified import.</p>

<p>It says that it takes a list of pairs of type <code>k</code> and <code>v</code> and returns a map
that maps from keys of type <code>k</code> to type <code>v</code>. Notice that when we were doing
association lists with normal lists, the keys only had to be equatable
(their type belonging to the <code>Eq</code> typeclass) but now they have to be
orderable. That's an essential constraint in the <code>Data.Map</code> module. It
needs the keys to be orderable so it can arrange them in a tree.</p>
<p>You should always use <code>Data.Map</code> for key-value associations unless you
have keys that aren't part of the <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Ord"><code>Ord</code></a> typeclass.</p>
<p><strong><a href="https://hackage.haskell.org/package/base/docs/Control-Applicative.html#v:empty"><code>empty</code></a></strong> represents an empty map. It takes no arguments, it just returns an
empty map.</p>

<p>These were just a few functions from <code>Data.Map</code>. You can see a complete
list of functions in the
<a href="http:https://www.haskell.org/ghc/docs/latest/html/libraries/containers/Data-Map.html#v%3Aassocs">documentation</a>.</p>
<h2 id="Data.Set">Data.Set<a class="anchor-link" href="#Data.Set">&#182;</a></h2><p><img src="img/legosets.png" title="legosets" style="float:right;margin-left:2em;" /></p>
<p>The <code>Data.Set</code> module offers us, well, sets. Like sets from mathematics.
Sets are kind of like a cross between lists and maps. All the elements
in a set are unique. And because they're internally implemented with
trees (much like maps in <code>Data.Map</code>), they're ordered. Checking for
membership, inserting, deleting, etc. is much faster than doing the same
thing with lists. The most common operation when dealing with sets are
inserting into a set, checking for membership and converting a set to a
list.</p>
<p>Because the names in <code>Data.Set</code> clash with a lot of <a href="https://hackage.haskell.org/package/base/docs/Prelude.html"><code>Prelude</code></a> and <code>Data.List</code>
names, we do a qualified import.</p>
<p>Put this import statement in a script:</p>

<p>Sets are often used to weed a list of duplicates from a list by first
making it into a set with <a href="https://hackage.haskell.org/package/base/docs/Data-List-NonEmpty.html#v:fromList"><code>fromList</code></a> and then converting it back to a list
with <strong><a href="https://hackage.haskell.org/package/base/docs/Data-Foldable.html#v:toList"><code>toList</code></a></strong>. The <code>Data.List</code> function <a href="https://hackage.haskell.org/package/base/docs/Data-List.html#v:nub"><code>nub</code></a> already does that, but weeding
out duplicates for large lists is much faster if you cram them into a

only requires the type of the list's elements to be part of the <code>Eq</code>
typeclass, whereas if you want to cram elements into a set, the type of
the list has to be in <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#t:Ord"><code>Ord</code></a>.</p>

<h2 id="Making-our-own-modules">Making our own modules<a class="anchor-link" href="#Making-our-own-modules">&#182;</a></h2><p><img src="img/making_modules.png" title="making modules" style="float:right;margin-left:2em;" /></p>
<p>We've looked at some cool modules so far, but how do we make our own
module? Almost every programming language enables you to split your code
up into several files and Haskell is no different. When making programs,
it's good practice to take functions and types that work towards a
similar purpose and put them in a module. That way, you can easily reuse
those functions in other programs by just importing your module.</p>
<p>Let's see how we can make our own modules by making a little module that
provides some functions for calculating the volume and area of a few
geometrical objects. We'll start by creating a file called <code>Geometry.hs</code>.</p>
<p>We say that a module <em>exports</em> functions. What that means is that when I
import a module, I can use the functions that it exports. It can define
functions that its functions call internally, but we can only see and
use the ones that it exports.</p>
<p>At the beginning of a module, we specify the module name. If we have a
file called <code>Geometry.hs</code>, then we should name our module <code>Geometry</code>. Then,
we specify the functions that it exports and after that, we can start
writing the functions. So we'll start with this.</p>

</div>

<p>As you can see, we'll be doing areas and volumes for spheres, cubes and
cuboids. Let's go ahead and define our functions then:</p>

<p>Pretty standard geometry right here. There are a few things to take note
of though. Because a cube is only a special case of a cuboid, we defined
its area and volume by treating it as a cuboid whose sides are all of
the same length. We also defined a helper function called <code>rectangleArea</code>,
which calculates a rectangle's area based on the lengths of its sides.
It's rather trivial because it's just multiplication. Notice that we
used it in our functions in the module (namely <code>cuboidArea</code> and
<code>cuboidVolume</code>) but we didn't export it! Because we want our module to
just present functions for dealing with three dimensional objects, we
used <code>rectangleArea</code> but we didn't export it.</p>
<p>When making a module, we usually export only those functions that act as
a sort of interface to our module so that the implementation is hidden.
If someone is using our <code>Geometry</code> module, they don't have to concern
themselves with functions that we don't export. We can decide to change
those functions completely or delete them in a newer version (we could
delete <code>rectangleArea</code> and just use <a href="https://hackage.haskell.org/package/base/docs/Prelude.html#v:-42-"><code>*</code></a> instead) and no one will mind
because we weren't exporting them in the first place.</p>
<p>To use our module, we just do:</p>

<p><code>Geometry.hs</code> has to be in the same folder that the program that's
importing it is in, though.</p>
<p>Modules can also be given a hierarchical structures. Each module can
have a number of sub-modules and they can have sub-modules of their own.
Let's section these functions off so that <code>Geometry</code> is a module that has
three sub-modules, one for each type of object.</p>
<p>First, we'll make a folder called <code>Geometry</code>. Mind the capital G. In it,
we'll place three files: <code>Sphere.hs</code>, <code>Cuboid.hs</code>, and <code>Cube.hs</code>. Here's what
the files will contain:</p>

<p>Alright! So first is <code>Geometry.Sphere</code>. Notice how we placed it in a
folder called <code>Geometry</code> and then defined the module name as
<code>Geometry.Sphere</code>. We did the same for the cuboid. Also notice how in all
three sub-modules, we defined functions with the same names. We can do
this because they're separate modules. We want to use functions from
<code>Geometry.Cuboid</code> in <code>Geometry.Cube</code> but we can't just straight up do
<code>import Geometry.Cuboid</code> because it exports functions with the same names as
<code>Geometry.Cube</code>. That's why we do a qualified import and all is well.</p>
<p>So now if we're in a file that's on the same level as the <code>Geometry</code>
folder, we can do, say:</p>

</div>

</div>
<div class="cell border-box-sizing code_cell rendered">
<div class="input">
<div class="prompt input_prompt">In&nbsp;[189]:</div>

</div><div class="inner_cell">
<div class="text_cell_render border-box-sizing rendered_html">
<p>And then we can call <code>area</code> and <code>volume</code> and they'll give us the area and
volume for a sphere. And if we want to juggle two or more of these
modules, we have to do qualified imports because they export functions
with the same names. So we just do something like:</p>

<div class="cell border-box-sizing text_cell rendered"><div class="prompt input_prompt">
</div><div class="inner_cell">
<div class="text_cell_render border-box-sizing rendered_html">
<p>And then we can call <code>Sphere.area</code>, <code>Sphere.volume</code>, <code>Cuboid.area</code>, etc. and
each will calculate the area or volume for their corresponding object.</p>
<p>The next time you find yourself writing a file that's really big and has
a lot of functions, try to see which functions serve some common purpose
and then see if you can put them in their own module. You'll be able to
just import your module the next time you're writing a program that
requires some of the same functionality.</p>
