Reprint: http://agileprogrammer.blogspot.com/2006/08/erlang-abstract-form-moduleform.html We will examine the composition of the Erlang Abstract form in detail. The method is simple, refer to the Abstract form section of the ERALNG document and validate it with practical examples.Abstract FormIn the Abstract form document, a function rep is used to represent a mapping from the

In r13a, Erlang has added support for Unicode. The data types covered in this article include: list, binary, modules involved Stdlib/unicode, Stdlib/io, Kernel/file. Binary The binary type attribute increases the UTF-related Type:utf8, UTF16, UTF32, which correspond to UTF8, UTF16,UTF32 encoding respectively. Binary Constructing When binary is built, if UTF correlation type is specified, then the value of the corresponding integer must be at: 0. 16#D7

Recently I needed to compare a few Erlang web libraries and frameworks for a friend who was writing a simple internal API endpoint. He suggested I shoshould publish the rundown f

through gen_tcp: Listen (). In this case, {active, false} is blocked, and then enters the acceptor_loop to start loop listening to client TCP requests. This cycle mainly involves three processes: 1. gen_accept () generates socket; 2. gen_tcp: controlling_process () assigns the socket communication to the newly generated transport process for processing; 3. set the {active, once} of transport to start receiving the message -- handle_info ({tcp, socket, Bin}, state) after the message is rece

IntroductionCharacterizing the scalability of Erlang.VMOn kernel-core processorsExplanation: Erlang schedulers are based on execution ction counting as a method for measuring execution time. A function is roughly equivalent to a function call. since each function call may take a different amount of time, the actual periods are not the same between different functions. when a process is scheduled to run, it is assigned a number of functions that it

1.1. High concurrency 1. Process The smallest Execution Unit of Erlang is a process, and the biggest feature of the process is good isolation (with its own independent memory space, crash will not affect other work units ). Erlang process features 2. coroutine Switch by yourself Efficient. Because the system context (such as page tables) is not frequently switched, the efficiency

Variablethe variable must start with an uppercase letter. in Erlang, variables are like those in math. When associating a value with a variable, it is an assertion, that is, a statement of fact. This variable is the value, that's all.Two assumptions about the simple statement of x=1234. First, x is not a variable, it's not a concept that you're used to in Java and C languages. Second, = is not an assignment operator, b
