+ <title>How to contribute</title>
+
+ <para>This project is driven by the Haskell community, so
+ contributions of all kinds are welcome. The first step is to join
+ the <ulink
+ url="http://www.haskell.org/mailman/listinfo/libraries">Haskell
+ libraries mailing list</ulink>, and maybe <ulink
+ url="http://www.haskell.org/pipermail/libraries/">browse the list
+ archives</ulink>. Some of the ways you can contribute are:</para>
+
+ <itemizedlist>
+ <listitem>
+ <para>By donating code: for libraries which don't yet have a
+ reference implementation, code is always welcome. Code that
+ conforms to the design guidelines (which aren't very strict,
+ see <xref linkend="library-design"/>) and comes with documentation
+ (<xref linkend="documentation"/>) and a test suite (<xref
+ linkend="testing"/>) is better, but these aren't essential. As
+ a library progresses through the stability scale (<xref
+ linkend="stability"/>) these things become more important, but
+ for an experimental library we're not going to worry too much
+ about this stuff.</para>
+
+ <para>See section <xref
+ linkend="contributing-reference-libraries"/> for details on
+ contributing new library code.</para>
+ </listitem>
+ <listitem>
+ <para>By porting code for an existing library to a new
+ compiler or architecture. A library is classed as portable if
+ it should be available regardless of which compiler/platform
+ combination you're using; however, many libraries are
+ non-portable for one reason or another (see <xref
+ linkend="portability"/>), and broadening the scope of these
+ libraries is always welcome.</para>
+ </listitem>
+ <listitem>
+ <para>Become a library maintainer: if you have a particular
+ interest in and/or knowledge about a certain library, and have
+ the time to spare, and the library in question doesn't already
+ have a maintainer, then you may be a suitable maintainer for
+ the library. The responsibilities of library maintainers are
+ given in <xref linkend="maintainership"/>. </para>
+ </listitem>
+ <listitem>
+ <para>Participating in the design process for new libraries,
+ and suggesting improvements to existing libraries. Everyone

+ <title>A possible extension</title>

+
+ <para>becomes</para>
+
+<programlisting>
+ import qualified Text.Xml.Parse

+
+ <para>It is usually more convenient to make use of Haskell's
+ <literal>as</literal> keyword to shorten qualified identifiers:</para>
+
+<programlisting>
+ import qualified Text.Xml.Parse as Parse
+ ... Parse.element f ...
+</programlisting>
+
+ <para>A possible extension to the proposal is to make this use
+ of <literal>as</literal> implicit, unless overridden by the
+ programmer with her own <literal>as</literal> clause. The
+ implicit <literal>as</literal> clause always uses the final

+
+ <para>Various proposals have been made to allow you to rename a

+ import Org.Com.Microsoft.* as Microsoft.*
+ import Microsoft.Foo

+ <title>Hierarchy design guidelines</title>
+
+ <para>Apart from the <literal>User</literal>,
+ <literal>Local</literal> and <literal>Org</literal> top-level
+ categories, the rest of the hierarchy is organised with a single
+ principle in mind:</para>
+
+ <blockquote>
+ <para>Modules are grouped by
+ <emphasis>functionality</emphasis>, since this is the single
+ property that is most helpful for a user of the library - we
+ want users to be able to find out where to obtain
+ functionality easily, and to easily find all the modules that
+ provide relevant functionality.</para>
+
+ <para>So, if two modules provide similar functionality, or
+ alternative interfaces to the same functionality, then they
+ should be children of the same node in the hierarchy. Modules
+ should not be grouped by standards compliance, portability,
+ stability, or any other property.</para>
+ </blockquote>
+
+ <para>It should be noted that this is a guideline rather than a
+ rule: sometimes it just isn't the right thing. For example, the
+ <literal>DotNet</literal> top-level name contains a mirror of
+ the Microsoft .NET base class library; if we had gone purely by
+ functionality then these libraries would have to be scattered
+ around the hierarchy, resulting in a situation where it would
+ probably be <emphasis>harder</emphasis> for a programmer to find
+ the functionality he or she is interested in.</para>
+
+ <para>There are some other considerations when choosing where to
+ place libraries. Where possible, choose a layout that finds a
+ good compromise between depth of nesting and logical grouping of
+ functionality; for example, although the <literal>Text</literal>
+ hierarchy could logically be placed as a child of
+ <literal>FileFormat</literal>, we choose not to because
+ <literal>Text</literal> is ubiquitous and we don't want to have
+ to type the extra component all the time.</para>
+
+ <para>Also consider consistency: if a particular sub-hierarchy
+ provides similar functionality to another sub-hierarchy in the
+ tree, then preferably the structure of the two subtrees should
+ also be similar. For example: under
+ <literal>Language.Haskell</literal> we have children
+ <literal>Syntax</literal>, <literal>Lexer</literal>,
+ <literal>Parser</literal> etc., so under
+ <literal>Language.C</literal> we should have a similar
+ structure.</para>

+ <para>We wish to accommodate source code from different

+ to tell whether they're violating the terms of the each license
+ or not).</para>
+
+ <para>So the solution is as follows: code under different
+ licenses will be clearly separate in the repository (i.e. in
+ separate subdirectories), and compilers are expected to present
+ packages of modules where all modules in a package fall under
+ the same license, and where the dependencies between packages
+ are clear.</para>
+
+ <para>It was decided that certain essential functionality should

+ following modules: <literal>Prelude</literal>,
+ <literal>Foreign</literal>, <emphasis>ToDo: what
+ else?</emphasis>.</para>
+
+ <para>There is one further requirement: reference libraries must
