Beginning Haskell: A Project-Based Approach by Alejandro Serrano Mena

By Alejandro Serrano Mena

Starting Haskell offers a broad-based creation to the Haskell language, its libraries and setting, and to the useful programming paradigm that's quick starting to be in value within the software program undefined. The booklet takes a project-based method of studying the language that's unified round the development of an online storefront. first-class insurance is given to the Haskell atmosphere and helping instruments. those contain the Cabal construct device for dealing with initiatives and modules, the HUnit and QuickCheck instruments for software program checking out, the Scotty framework for constructing internet functions, power and Esqueleto for database entry, and in addition parallel and allotted programming libraries.

Functional programming is collecting momentum, permitting programmers to precise themselves in a extra concise means, decreasing boilerplate and lengthening the security of code. certainly, mainstream languages reminiscent of C# and Java are adopting gains from practical programming, and from languages enforcing that paradigm. Haskell is a sublime and noise-free natural sensible language with an extended background, having an immense variety of library individuals and an lively group. This makes Haskell the simplest instrument for either studying and using useful programming, and starting Haskell the right publication to teach off the language and what it will possibly do.

* Takes you thru a chain of tasks exhibiting different elements of the language.
* presents an outline of crucial libraries and instruments within the Haskell ecosystem.
* Teaches you the way to use sensible styles in real-world eventualities.

The Principles of Object-Oriented JavaScript

If you’ve used a extra conventional object-oriented language, comparable to C++ or Java, JavaScript most likely doesn’t look object-oriented in any respect. It has no suggestion of sessions, and also you don’t even have to outline any items to be able to write code. yet don’t be fooled—JavaScript is a really strong and expressive object-oriented language that places many layout judgements correct into your arms.

The Ruby Programming Language

The Ruby Programming Language is the authoritative consultant to Ruby and gives entire insurance of types 1. eight and 1. nine of the language.

It used to be written (and illustrated! ) by means of an all-star team:
• David Flanagan, bestselling writer of programming language "bibles" (including JavaScript: The Definitive advisor and Java in a Nutshell) and committer to the Ruby Subversion repository.
• Yukihiro "Matz" Matsumoto, writer, dressmaker and lead developer of Ruby and writer of Ruby in a Nutshell, which has been elevated and revised to develop into this book.

Why the fortunate stiff, artist and Ruby programmer extraordinaire. This ebook starts with a quick-start instructional to the language, after which explains the language intimately from the ground up: from lexical and syntactic constitution to datatypes to expressions and statements and on via tools, blocks, lambdas, closures, periods and modules.

The booklet additionally incorporates a lengthy and thorough advent to the wealthy API of the Ruby platform, demonstrating -- with heavily-commented instance code -- Ruby's amenities for textual content processing, numeric manipulation, collections, input/output, networking, and concurrency. a whole bankruptcy is dedicated to Ruby's metaprogramming capabilities.

The Ruby Programming Language files the Ruby language definitively yet with out the formality of a language specification. it really is written for knowledgeable programmers who're new to Ruby, and for present Ruby programmers who are looking to problem their figuring out and elevate their mastery of the language.

Database. In this case, we want to find things. executing the operation. [ 44 ] Chapter 3 • The second argument is the callback, to be called with the reply of the query. We expect the reply to have a status key, with a value indicating if the operation was successful or not. °° In the case of a successful operation (the value of status being ok), we send a response back to the responder of the original event (in our case, the client code in the web browser). The responder is handed the mindMaps result from the database, which can be found in the results key of the reply object.

The name of each mind map displayed. x since, in which case the list will be empty). To see some results, proceed to the next section. [ 30 ] Chapter 2 Creating a mind map Listing the mind maps isn't very useful by itself. We need to be able to create some as well. Let's add the HTML markup first. js"> We have added a

tag with the create-form CSS class. Inside the form, we have a text input field and a standard form submit button. mindMaps, function() { renderListItem(this); }) }) }; The handler function grabs the name input from the form and assigns it to the local nameInput variable.

The value of the nameInput field is also cleared, so that the form is ready for adding the next mind map. Finally, the handler returns false, which lets jQuery know that it should stop the submission event from propagating further. When you now reload the page, you will be able to create mind maps using the form, and they will appear in the list when the form is submitted. Deleting a mind map The final operation that we still need to add is deletion. In the list of mind maps, we want to have a delete button next to each mind map.
