![]() Now let’s develop a first Scala Hello World application. That’s all you need to do in order to setup Scala on your Mac. To activate this changes you need to reopen Terminal and execute there the following command: profile:Įxport PATH=”/Users/your_user/scala/bin:$PATH”ĥ. In this section, Ill show you how to install the Scala REPL on Linux, MacOS, and Windows using a package manager. So you need to add the following line in the. profile file you can fix this by creating it. Move the scala folder to /Users/user_nameĤ. When you browse the scala directory you can find there folders: bin, doc, examples, … etc.ģ. Unzip the archive and rename a folder in “scala”. It helps to have recently updated your macports tree: sudo port selfupdate. When this article was written the version of Scala was 2.10.2Ģ. The first thing you need to do is find the latest available version of scala. Download scala-X.XX.tgz from the official site. The program relates to Development Tools. Enough words, let’s continue with practical steps.ġ. The 5.1.10.241 version of Scala is available as a free download on our website. Further I will write the same post but applied for Windows. In this post I’m going to make an overview of Scala installation on Mac OS. Learning of any programming language starts from setting up of environment. I don’t want to write a lot of paragraphs about Scala advantages which were crucial in my decision. As you can see looking on the topic, the new language is Scala. Scala is being used everywhere and importantly in enterprise web applications.Not so long time ago I decide to improve my programming skills with a new programming language. Scala has a set of features that completely differ from Java. It allows you to write codes in an immutable manner, which makes it easy to apply concurrency and parallelism (Synchronize). It reduces the number of lines and helps the programmer to code in a type-safe way. Scala allows you to express general programming patterns in an effective way. Scala can do Concurrent & Synchronize processing Scala enables you to use all the classes of the Java SDK and also your own custom Java classes, or your favorite Java open source projects. The ' scala' command is similar to the java command, in that it executes your compiled Scala code. The Scala compiler compiles your Scala code into Java Byte Code, which can then be executed by the ' scala' command. This means that Scala and Java have a common runtime platform. You can get Homebrew by following the instructions on it’s website. Homebrew makes your life a lot easier when it comes to installing applications and languages on a Mac OS. Here is a Step by Step guide to installing Scala and Apache Spark on MacOS. Scala is compiled into Java Byte Code which is executed by the Java Virtual Machine (JVM). How to Install Scala and Apache Spark on MacOS. You don't have to specify a type in most cases, and you certainly don't have to repeat it. Scala, unlike some of the other statically typed languages (C, Pascal, Rust, etc.), does not expect you to provide redundant type information. These concepts will be explained in subsequent chapters. Scala provides a lightweight syntax for defining anonymous functions, it supports higher-order functions, it allows functions to be nested, and supports currying. Scala is also a functional language in the sense that every function is a value and every value is an object so ultimately every function is an object. Types and behavior of objects are described by classes and traits which will be explained in subsequent chapters.Ĭlasses are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance. Scala is a pure object-oriented language in the sense that every value is an object. ![]() Here we have presented a few points that makes Scala the first choice of application developers. Many existing companies, who depend on Java for business critical applications, are turning to Scala to boost their development productivity, applications scalability and overall reliability. Scala is compiled to run on the Java Virtual Machine. Scala smoothly integrates the features of object-oriented and functional languages. ![]() Scala, short for Scalable Language, is a hybrid functional programming language.
