<p><em>We have received the following grant application. Please leave fe=

<h1>Modern Object Oriented Programming in Perl</h1>
<ul>
<li><p>Name:</p>
<p>Toby Inkster</p></li>
<li><p>Amount Requested:</p>
<p>USD 4,000</p></li>
</ul>
<h2>Synopsis</h2>
<p>The proposal is to write a book on Modern OO programming techniques u=
sing Moose, Moo, and (where applicable) Class::Tiny. This would be writt=
en in a similar style to chromatic's <em>Modern Perl</em> book, followin=
g the same test-driven approach to development, but covering modern Perl=
OO programming tools, techniques, and patterns in greater depth.</p>
<p>The primary target audience would be people who are already familiar =
with programming in Perl, but want to learn about modern object-oriented=
programming techniques, using Moose and Moo. A secondary target audienc=
e would be non-Perl programmers wishing to learn about object-oriented c=
oncepts which might not be available in the programming languages they a=
re familiar with (e.g. many OO programming languages do not support the =
concept of roles) and expose themselves to ideas that might make them be=
tter OO programmers overall.</p>
<p>The starting point for the book would be <a href=3D"http://en.wikiboo=
ks.org/wiki/C_Sharp_Programming">C# Programming</a>, a book available on=
the Wikibooks website under the Creative Commons Attibution-ShareAlike =
licence, and the completed project would thus be made available under th=
e same licence.</p>
<h2>Benefits to the Perl Community</h2>
<p>The project will aim to make Moose and Moo more understandable to Per=
l programmers, and also aim to make programmers outside the Perl program=
ming community look at Perl afresh and understand that it may have somet=
hing to offer them.</p>
<p>Because Moose shares similarities with both Steven Little's proposed =
metaobject protocol for the Perl 5 core, and with Perl 6's object model,=
it is hoped that the book will provide a foundation for future books or=
tutorials on these.</p>
</div>
<div id=3D"more" class=3D"asset-more">
<h2>Deliverables</h2>
<ul>
<li><p>A book in at least 16 chapters, each of a similar length and dept=
h to those in the C# book covering the following topics (the list of top=
ics mostly being derived from the C# book):</p>
<ul>
<li><p>Introduction</p>
<p>An introduction to the book, and references to other books for establ=
ishing foundation knowledge upon which this book will build. It would in=
troduce the concept of metaprogramming, but not explain in much depth ho=
w to do it.</p></li>
<li><p>Namespaces</p>
<p>Giving your code its own space to live in.</p></li>
<li><p>Classes and Methods</p>
<p>The blueprints for objects that describe how they should work.</p></l=
i>
<li><p>Objects</p>
<p>Cornerstones of any object-oriented programming language, objects are=
the tools you use to perform work.</p></li>
<li><p>Encapsulation and accessor levels</p>
<p>Explains protection of object states by encapsulation, or the bundlin=
g of an object's data and functionality. (This would be quite substantia=
lly rewritten.)</p></li>
<li><p>Lazily built attributes</p>
<p>(A new chapter demonstrating programming patterns based on lazily-bui=
lt attributes.)</p></li>
<li><p>Type constraints and coercions</p>
<p>(C# is a typed language, so Perl would need a completely different tr=
eatment. This chapter would be written from scratch.)</p></li>
<li><p>Roles</p>
<p>(These are not covered by the C# book, so this chapter would be writt=
en from scratch, but I may be able to re-use some material from the C# c=
hapter on abstract classes.)</p></li>
<li><p>Interfaces</p>
<p>Define a template, on which to base sub-classes. (This would require =
significant rewriting from C#, and would discuss using roles as a way to=
formalize common interfaces.)</p></li>
<li><p>Delegation and callbacks</p>
<p>Learn about delegation and callbacks. (This is likely to also involve=
significant rewriting from the C# chapter on delegation and events. Thi=
s may cover dependency injection, or dependency injection may be split o=
ut into a separate chapter.)</p></li>
<li><p>Traits</p>
<p>(This would be a new chapter written from scratch about the run-time =
application of roles to objects and classes.)</p></li>
<li><p>Inheritance</p>
<p>Re-using existing code to improve or specialize the functionality of =
an object.</p></li>
<li><p>Exceptions</p>
<p>Responding to errors that can occur. (This would cover defining excep=
tion classes, and throwing and catching exceptions. It would also list s=
ome common exceptions thrown from within Moose, and give examples of cat=
ching them.)</p></li>
<li><p>Object Lifetime</p>
<p>Learn about the lifetime of objects, where they are allocated and lea=
rn about garbage collection.</p></li>
<li><p>Design Patterns</p>
<p>Learn commonly used design methodologies to simplify and/or improve y=
our development framework.</p></li>
<li><p>Metaprogramming Techniques</p>
<p>(A new from-scratch chapter introducing the Moose MOP, and discussing=
some limited ways of metaprogramming Moo - e.g. wrapping the \<code>has=
\</code> keyword.)</p></li>
</ul>
<p>The book would be made available in pod as a CPAN distribution, and i=
n HTML on the author's website. The source materials for the book would =
be mirrored on both GitHub.com and Bitbucket.org.</p>
<p><p>The CPAN distribution would also include executable scripts for ke=
y examples from the book.</p></li>
<li><p>A <code>Task::*</code> module would be uploaded to CPAN for one-s=
tep installation of all the modules covered by the book, and all the mod=
ules necessary to execute the example scripts provided.</p></li>
<li>If porting the C# examples to Perl brings to light any deficiencies =
in <a href=3D"https://metacpan.org/pod/Moose">Moose</a> or <a href=3D"ht=
tps://metacpan.org/pod/Moo">Moo</a>, whereby there are key OO ideas from=
C# that cannot be replicated in these frameworks, these will be discuss=
ed with the maintainers of those projects, and the best way to proceed w=
ill be decided. This may lead to improvements to <a href=3D"https://meta=
cpan.org/pod/Moose">Moose</a> or <a href=3D"https://metacpan.org/pod/Moo=
">Moo</a>, or the release of new <code>MooseX::*</code> or <code>MooX::*=
</code> extension modules.</li>
</ul></p>
<h2>Project Details</h2>
<p>The proposed title of the book, <em>Modern Object Oriented Programmin=
g in Perl</em> is a working title and subject to change. The chapter lis=
t may be rearranged slightly in the final version, with some chapters pe=
rhaps being merged, and others possibly split if they seem too lengthy.<=
/p>
<p>The code samples will primarily use <a href=3D"https://metacpan.org/p=
od/Moose">Moose</a> and <a href=3D"https://metacpan.org/pod/Moo">Moo</a>=
. When possible, sample code will be provided for both frameworks, so th=
at they can be compared side-by-side. For some advanced topics, Moo may =
not offer sufficient facilities, so only a Moose example would be provid=
ed. For some very basic topics, <a href=3D"https://metacpan.org/pod/Clas=
s::Tiny">Class::Tiny</a> and/or <a href=3D"https://metacpan.org/pod/Role=
::Tiny">Role::Tiny</a> code samples would also be provided. (The reason =
for this choice is that Role::Tiny is the basis for Moo's role system, a=
nd that there are tentative plans to enable some level of integration be=
tween Moo and Class::Tiny.)</p>
<p>The book may mention, but will not cover in any level of detail other=
Perl object-oriented frameworks such as <a href=3D"https://metacpan.org=
/pod/Mouse">Mouse</a>, <a href=3D"https://metacpan.org/pod/Moops">Moops<=
/a>, p5-mop, or <a href=3D"https://metacpan.org/pod/Class::Accessor">Cla=
ss::Accessor</a>. The book will not cover ""do-it-yourself"" techniques =
for writing constructors an accessors, except perhaps for comparison to =
demonstrate the superior approach of using an OO framework.</p>
<p>Overall the book would encourage correctness, robustness, encapsulati=
on, and non-repetitive design rather than writing especially memory-effi=
cient or fast code, but optimization techniques may be touched on, and t=
he compromises involved may be discussed.</p>
<p>The chapter on type constraints and coercions will cover Moose's and =
Moo's built-in type constraint systems, but will concentrate on <a href=3D=
"https://metacpan.org/pod/Type::Tiny">Type::Tiny</a>, a standalone type =
constraint framework which supports both Moose and Moo. (Disclaimer: I a=
m the developer of Type::Tiny.)</p>
<p>The chapter on exceptions will use <a href=3D"https://metacpan.org/po=
d/Try::Tiny">Try::Tiny</a> and <a href=3D"https://metacpan.org/pod/Throw=
able">Throwable</a>.</p>
<p>The chapter on encapsulation will make use of <a href=3D"https://meta=
cpan.org/pod/Lexical::Accessor">Lexical::Accessor</a>. (Disclaimer: I am=
also the developer of Lexical::Accessor.)</p>
<h2>Inch-stones</h2>
<p>The progress of the project as a whole can be measured by the complet=
ion of each chapter. Chapters will not necessarily be completed in the o=
rder which they are intended to appear in the book. (The introduction is=
in fact, likely to be the final chapter written.)</p>
<p>Naturally until the whole book is complete, even a chapter which is "=
"complete"" will be subject to revisions -- it is not frozen in stone.</=
p>
<h2>Project Schedule</h2>
<p>My estimate is that each chapter will require two to three days of so=
lid work on average. (Chapters which mostly replicate the original C# bo=
ok will take less; chapters which require substantial original work, som=
ewhat more.) Additionally, I estimate roughly a week will be needed to s=
titch the completed chapters together into a cohesive whole.</p>
<p>I plan to dedicate roughly two days a week to the project, over the c=
ourse of about four months. The planned start for the project is Septemb=
er 2014, with a planned completion date in January or February 2015.</p>=
<h2>Completeness Criteria</h2>
<p>All the chapters will be available in pod, on CPAN, under a free lice=
nce.</p>
<p>(Which is not to say that I'll abandon it thereafter. If errors or om=
issions are pointed out after the end of the grant, or if new versions o=
f <a href=3D"https://metacpan.org/pod/Moose">Moose</a> or <a href=3D"htt=
ps://metacpan.org/pod/Moo">Moo</a> are released which make the book inco=
rrect, I intend to continue updating the book for the foreseeable future=
.)</p>
<h2>Bio</h2>
<p>I am a freelance developer based in the UK who uses Perl as his prefe=
rred programming language, though also develops actively in PHP and Java=
script, and dabbles occasionally in other programming languages. I am th=
e author of over 200 CPAN distributions, including many extensions to <a=
href=3D"https://metacpan.org/pod/Moose">Moose</a> and <a href=3D"https:=
//metacpan.org/pod/Moo">Moo</a>. </p>
<p>I am the primary developer of <a href=3D"https://metacpan.org/pod/Typ=
e::Tiny">Type::Tiny</a> and <a href=3D"https://metacpan.org/pod/Moops">M=
oops</a>, each of which are frameworks designed to integrate with both M=
oo and Moose, which has taught me a great deal about the differences and=
similarities between them. Type::Tiny and Moops were each included in t=
he top 10 best distributions created in 2013, <a href=3D"http://niceperl=
.blogspot.co.uk/2014/01/best-perl-distributions-created-at-2013.html">ac=
cording to ratings on MetaCPAN</a>. Type::Tiny now has over 100 other CP=
AN distributions listing it as a direct dependency.</p>
<p>I have contributed, albeit often in minor ways, to many of the module=
s that I propose to cover in the book. I am listed as a contributor to <=
a href=3D"https://metacpan.org/pod/Moo">Moo</a>, <a href=3D"https://meta=
cpan.org/pod/Role::Tiny">Role::Tiny</a>, and <a href=3D"https://metacpan=
.org/pod/Class::Tiny">Class::Tiny</a>, according to their respective doc=
umentation; to <a href=3D"https://metacpan.org/pod/Throwable">Throwable<=
/a>, according to its change log; and to p5-mop-redux, according to GitH=
ub.</p>
<p>I have written an article on the O'Reilly Programming Blog comparing =
Moose roles with similar approaches for horizontal code reuse in other p=
rogramming languages. See <a href=3D"http://programming.oreilly.com/2014=
/01/horizontal-reuse-an-alternative-to-inheritance.html">http://programm=
ing.oreilly.com/2014/01/horizontal-reuse-an-alternative-to-inheritance.h=
tml</a>.</p>
<p>Raised in both Australia and the UK, I speak English natively.</p>

<p>I like the concept but I have a few concerns about this proposal.</p>=
<p>First, the submitter doesn't have much writing experience other than =
a single article to point to. Typically, book proposals are submitted wi=
th at least one sample chapter. I think that would be appropriate for th=
is grant proposal too.</p>
<p>Second, and perhaps more concerning, is that there is no mention of h=
ow editing and tech review will be done for this book. My experience as =
a book author tells me that both of these things are crucial for creatin=
g a solid end product.</p>
<p>I imagine tech reviewing could be obtained by simply asking people in=
the community to read the book and contribute changes via git, and woul=
dn't require additional funds. However, getting someone to act as an edi=
tor might take actual money.</p>

<p>I really like Toby's code on CPAN. I like the fact that you can conta=

<p>When the qualitiy of this book is as good as his code I really say "Y=

<p>I really hope that the book will focus on the Perl (scripting languag=

yinkster.co.uk/blog/2012/05/12/byo-big-brother/" rel=3D"nofollow">here</=
a> and <a href=3D"http://blogs.perl.org/users/toby_inkster/" rel=3D"nofo=
llow">here</a>, though blogging is a somewhat different style of writing=
than you'd expect in a book.</p>
<p>Many of my CPAN releases include extensive documentation, and sometim=
es mini-tutorials. Examples include <a href=3D"https://metacpan.org/pod/=
release/TOBYINK/Type-Tiny-0.043_03/lib/Type/Tiny/Manual/Libraries.pod" r=
el=3D"nofollow">Type::Tiny::Manual::Libraries</a>, <a href=3D"https://me=
tacpan.org/pod/distribution/Kavorka/lib/Kavorka/Manual/MultiSubs.pod" re=
l=3D"nofollow">Kavorka::Manual::MultiSubs</a>, and <a href=3D"https://me=
tacpan.org/pod/Set::Equivalence" rel=3D"nofollow">Set::Equivalence</a>. =
Another good example is <a href=3D"https://metacpan.org/pod/distribution=
/Moops/lib/Moops/Manual/Objects101.pod" rel=3D"nofollow">Moops::Manual::=
Objects101</a> which is somewhat relevant as it is a port of <a href=3D"=
http://en.wikibooks.org/wiki/A-level_Computing/AQA/Problem_Solving,_Prog=
ramming,_Operating_Systems,_Databases_and_Networking/Programming_Concept=
s/Object-oriented_programming_(OOP)" rel=3D"nofollow">an object-oriented=
programming tutorial in another programming language</a> (in this case,=
Visual Basic) to Perl; in some ways a miniature version of what I hope =
to produce if given this grant.</p>
<p>Regarding technical review, as per my open source code, I would be wr=
iting all this "in the open", with a repository on GitHub (and mirrored =
on Bitbucket.org). Feedback on any aspect of the writing as it progresse=
d would be not only welcomed, but actively encouraged. I'd also frequent=
ly upload "checkpoints" to the CPAN as developer releases (i.e. containi=
ng underscores in the version number) to ensure as wide as possible an a=
udience for the work in progress.</p>
<p>There are a couple of people that I would have loved to ask to edit t=
he book, but I couldn't really expect them to donate their time without =
any recompense. I was conscious of keeping the amount requested as low a=
s feasible, so didn't want to add the cost of hiring an editor to it. I =
will note that the Attribution-ShareAlike License would allow for edited=
versions to be produced afterwards.</p>
<p>Addressing one of Andreas Mock's points:</p>
<p>A "cookbook" does indeed sound like a very good idea. It could take t=
he form of a multi-author blog, or a wiki. I think that is certainly som=
ething to bear in mind for publishing the HTML version of the book.<br/>=

<p>Because I've been asked about it on IRC, here are a list of general p=
rinciples I hope to encourage through the book:</p>

<li><p><a href=3D"http://en.wikipedia.org/wiki/Dependency_injection" rel=

<li><p><a href=3D"http://en.wikipedia.org/wiki/Immutable_object" rel=3D"=

></li>
<li><p>Encapsulation: <a href=3D"http://c2.com/cgi/wiki?LawOfDemeter" re=

lDontAsk" rel=3D"nofollow">tell, don't ask</a>; distinguishing between p=
ublic and internal APIs.</p></li>
</ul>
<p>They won't be given their own chapters, not because they're too unimp=
ortant, but because they're too important. The concepts will be introduc=
ed early on, in the chapters about classes, objects, and encapsulation, =
and the principles will be followed in all the later chapters.</p>

<p>The initial focus would be to get it online as POD and HTML.</p>
<p>That said, I'm planning on re-using chromatic's authoring tools (whic=

t could be done if there is demand for it.</p>
<p>Certain ideas like showing side-by-side code samples for Moo and Moos=

<p>This sounds like a good idea. I would prefer more text spent on Moose=
than Moo since it is the main beast of the Perl OOP. </p>
<p>I would also be interested in a good section on Design Patterns. Alth=

ok on design patterns for awhile now. Most books that talk about design =
patterns are for Ruby/C++/Java, ect. I would love to have the topic cove=

<p>Toby asked my opinion on drafts of this proposal and revised them per=
my suggestions. The Perl community has long needed a book on this subje=
