What is Erlang? Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance.
Erlang ( / ˈɜːrlæŋ / UR-lang) is a general-purpose, concurrent, functional high-level programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in ...
Erlang Tutorial - Erlang is a general purpose or you might say a functional programming language and runtime environment. It was built in such a way that it had inherent support for concurrency, distribution and fault tolerance. Erlang was originally developed to be used in several large telecommunication systems. Bu
The official home of the Erlang Programming Language. Download Erlang/OTP. The latest version of Erlang/OTP is 27.0.To install Erlang you can either build it from source or use a pre-built package.. Take a look at the Erlang/OTP 27 release description to see what changes Erlang/OTP 27 brings over the previous major version.. The Erlang/OTP version scheme is described in the Erlang/OTP Systems Principles Guide.
Erlang/OTP Documentation. Online documentation for the latest version of the run-time system as well as all the libraries. Programming Erlang: Software for a Concurrent World (Limited Free) Programming Erlang: Software for a Concurrent World (Joe Armstrong) is a book about Erlang written by one of the original inventors, published in 2007.
Erlang's distribution mechanisms are transparent: programs need not be aware that they are distributed. The OTP libraries provide support for many common problems in networking and telecommunications systems. The Erlang runtime environment (a virtual machine, much like the Java virtual machine) means that code compiled on one architecture runs anywhere. The runtime system also allows code in a running system to be updated without interrupting the program.
Feb 1, 2020 · Syntax. Erlang makes heavy use of recursion. Since data is immutable in Erlang, the use of while and for loops (where a variable needs to keep changing its value) is not allowed. Here’s an example of recursion, showing how a function repeatedly strips the first letter from the front of a name and prints it, only stopping when the last letter ...
View Source Erlang/OTP 27.0. Welcome to Erlang/OTP, a complete development environment for concurrent programming. The Erlang language is described in the Erlang Reference Manual. An Erlang tutorial can be found in Getting Started With Erlang. In addition to the documentation here Erlang is described in several books like:
Apr 29, 2021 · An Erlang is a unit of telecommunications traffic measurement. Strictly, an Erlang represents the continuous use of one voice path. In practice, it is used to describe the total traffic volume of one hour. For example, if a group of user made 30 calls in one hour and each call had an average call duration of 5 minutes, then the traffic figure ...
Now, we defined Erlang as a functional programming language, but there's also a large emphasis on concurrency and high reliability. To be able to have dozens of tasks being performed at the same time, Erlang uses the actor model, and each actor is a separate process in the virtual machine.
Oct 28, 2009 · Erlang will select the most appropriate version given the arguments received. (Config is a structure of type #config which has a type attribute). That means it is very easy and much clearer than chaining if/else or switch/case to make business rules. To wrap up. Writing scalable servers, that's the whole point of erlang. Everything is designed it making this easy. On the two previous features, I'd add :
Erlang has three significant advantages over other programming languages, which mainly stem from the unique way the language is built. Concurrency. BEAM, the Erlang virtual machine, uses lightweight threads of execution (called processes). These are isolated, run across all CPUs, and communicate through messages.
Erlang is a programming language and runtime system for building massively scalable soft real-time systems with requirements on high availability..

This section is a quick start tutorial to get you started with Erlang. Everything in this section is true, but only part of the truth. For example, only the simplest form of the syntax is shown, not all esoteric forms. Also, parts that are greatly simplified are indicated with manual. This means that a lot more information on the subject is to ...
Feb 16, 2023 · Erlang is a programming language that is well-suited for concurrent and distributed systems. One useful feature of Erlang is the ability to inspect the call stack, which is a record of the sequence of function calls that have led to the current point in the program's execution. This can be helpful for debugging purposes, or for gaining a better und. 2 min read.
Everything in this section is true, but only part of the truth. For example, only the simplest form of the syntax is shown, not all esoteric forms. Also, parts that are greatly simplified are indicated with *manual*. This means that a lot more information on the subject is to be found in the Erlang book or in Erlang Reference Manual.

On Windows, open a command prompt window and type "werl", or find the Erlang icon in the programs menu). To run the program from the Erlang shell:
Erlang - Overview - Erlang is a functional programming language which also has a runtime environment. It was built in such a way that it had integrated support for concurrency, distribution and fault tolerance. Erlang was originally developed to be used in several large telecommunication systems from Ericsson.
1 Introduction. 1.1 Introduction. This is a "kick start" tutorial to get you started with Erlang. Everything here is true, but only part of the truth. For example, I'll only tell you the simplest form of the syntax, not all esoteric forms. Where I've greatly oversimplified things I'll write *manual* which means there is lots more information to ...
The language constructs are described in text and with examples rather than formally specified. This is to make the manual more readable. The Erlang reference manual is not intended as a tutorial. Information about implementation of Erlang can, for example, be found, in the following: System Principles. Starting and stopping, boot scripts, code ...
In this section, all valid Erlang expressions are listed. When writing Erlang programs, it is also allowed to use macro and record expressions. However, these expressions are expanded during compilation and are in that sense not true Erlang expressions. Macro and record expressions are covered in separate sections:
