Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional 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, and a set of design principles for Erlang programs.

Next message (by thread): [erlang-questions] make_ref bug or feature? Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I was putting Refs into a term and then serializing them with term_to_binary and sending them into a socket to another independent Erlang system (ie not using distributed Erlang) - so yes it was a problem since I'd assumed these were unique.

I got a question from Ivo Danihelka about make_ref(). Isn't make_ref() supposed to generate "an almost unique reference" the manual says "Returns an almost unique reference. The returned reference will re-occur after approximately 2^82 calls; therefore it is unique enough for practical purposes." If I start two erlang shells and evaluate the following in both shells: 1> io:format("~p~n",[term

The Node term is an encoded atom, that is, ATOM_EXT , SMALL_ATOM_EXT , or ATOM_CACHE_REF . The ID field contains a big-endian unsigned integer, but is to be regarded as uninterpreted data , as this field is node-specific. A reference is a term which is unique in an Erlang runtime system, created by calling make ref/0. 1.2.6 Fun A fun is a functional object.

The Erlang services are always distributed, default is to use the service name as (short) node-name. DebugType: Can be one of none (default), new, reuse or console. Specifies that output from the Erlang shell should be sent to a "debug log".

be manipulated with Erlang's `:binary` module * Reference - a unique value in the runtime system, created with `make_ref/0` ### Data types: Elixir also provides other data types that are built on top of the types: listed above. Some of them are: * `Date` - `year-month-day` structs in a given calendar Note: yes, the standard library and the VM's kernel are applications themselves, which means that Erlang is a language used to build OTP, but whose runtime environment depends on OTP to work. It's circular. This gives you some idea of why the language is officially named 'Erlang/OTP'. Type Specifications and Erlang PLTs Are The Best Sandwiches. Back in Types (or lack thereof), I introduced Dialyzer, a tool to find type errors in Erlang.This chapter puts its full focus on Dialyzer and how to actually find some type errors with Erlang, and how to use the tool to find other types of discrepancies.

An important feature of the Erlang programming language is the ability to change module code in runtime, code replacement, as described in the Erlang Reference Manual. Based on this feature, the OTP application SASL provides a framework for upgrading and downgrading between different versions of an entire release in runtime. be manipulated with Erlang's `:binary` module * Reference - a unique value in the runtime system, created with `make_ref/0` ### Data types: Elixir also provides other data types that are built on top of the types: listed above.
