Erlang. Erlang is (un)widely known from it’s easiness of building distributed systems. A system written in Erlang can run great, despite being deployed on one, two or hundred machines. But even though it’s amazing in it’s particular niche, it also has unique syntax solutions that make it nice to develop in. Pattern matching

# erlang # elixir # bits. Istvan Apr 29, 2020 ・5 min read. In Erlang, it is easy to construct binaries and bitstrings and matching binary patterns. I was running into Mitchell Perilstein's excellent work on NTP with Erlang and I thought I am going to use this to explain how bitstrings and binaries work in Erlang. A pattern matching operation needs at least 2 parts: a pattern, and a term against wich the pattern is matched.

Erlang pattern matching

Pattern matching occurs when evaluating a function call, case - receive - try - expressions and match operator (=) expressions. In a pattern matching, a left-hand side pattern is matched against a right-hand side term. If the matching Like many other functional languages, Erlang has powerful pattern matching capabilities. Typically, a pattern (left side) is matched against a term (right side).

Feb 24, 2009 Mailbox processing with pattern matching. Let's look at these principles in more detail. An actor is a process that executes a function. Here a

Unlike functions in Erlang and LFE, arithmetic operators in Lisp are variadic (or n-ary), able to take any number of arguments. Lambda expressions and function definition.

If a match succeeds and the optional guard sequence Chapter 4. Logic and Recursion So far, Erlang seems logical but fairly simple. Pattern matching controls the flow through a program, and requests that match a Patterns aren't good at expressing ranges of values or types of data.

Pattern matching occurs when evaluating a function call, case - receive - try - expressions and match operator (=) expressions. In a pattern matching, a left-hand side pattern is matched against a right-hand side term. If the matching succeeds, any unbound variables in the pattern become bound. If the matching fails, a run-time error occurs. Examples:
