This document outlines general guidelines for those writing and publishing Elixir libraries meant to be consumed by other developers. Getting startedYou can create a new Elixir library by running the mix new command: $ mix new my_library The project name is given in the snake_case convention where all letters are lowercase and words are separate with underscores. This is the same convention used b

What we'll needThe only thing we'll need for this guide is a working Phoenix application. For those of us who need a simple application to deploy, please follow the Up and Running guide. L

In this guide, we will build a complete Elixir application, with its own supervision tree, configuration, tests, and more. The requirements for this guide are (see elixir -v): Elixir 1.18.0 onwardsErlang/OTP 27 onwardsThe application works as a distributed key-value store. We are going to organize key-value pairs into buckets and distribute those buckets across multiple nodes. We will also build a

Typespecs are not set-theoretic typesElixir is in the process of implementing its own type system based on set-theoretic types. Typespecs, which are described in the following document, are a distinct notation for declaring types and specifications based on Erlang. Typespecs may be phased out as the set-theoretic type effort moves forward. Elixir is a dynamically typed language, and as such, type

In this chapter we will learn more about Elixir basic types: integers, floats, booleans, atoms, and strings. Other data types, such as lists and tuples, will be explored in the next chapter. iex> 1 # integer iex> 0x1F # integer iex> 1.0 # float iex> true # boolean iex> :atom # atom / symbol iex> "elixir" # string iex> [1, 2, 3] # list iex> {1, 2, 3} # tupleBasic arithmeticOpen up iex and type the

In the previous chapter, we used agents to represent our buckets. In the introduction to mix, we specified we would like to name each bucket so we can do the following: CREATE shopping OK PUT shopping milk 1 OK GET shopping milk 1 OKIn the example session above we interacted with the "shopping" bucket by referencing its name. Therefore, an important feature in our key-value store is to give names

Elixir does not provide loop constructs. Instead we leverage recursion and high-level functions for working with collections. This chapter will explore the former. Loops through recursionDue to immutability, loops in Elixir (as in any functional programming language) are written differently from imperative languages. For example, in an imperative language like C, one would write: for(i = 0; i < si

Now let's talk about associative data structures. Associative data structures are able to associate a key to a certain value. Different languages call these different names like dictionaries, hashes, associative arrays, etc. In Elixir, we have two main associative data structures: keyword lists and maps. Keyword listsKeyword lists are a data-structure used to pass options to functions. Let's see a

In this chapter, we will learn about the case, cond, and if control flow structures. casecase allows us to compare a value against many patterns until we find a matching one: iex> case {1, 2, 3} do ...> {4, 5, 6} -> ...> "This clause won't match" ...> {1, x, 3} -> ...> "This clause will match and bind x to 2 in this clause" ...> _ -> ...> "This clause would match any value" ...> end "This clause w

In this chapter, we will learn why the = operator in Elixir is called the match operator and how to use it to pattern match inside data structures. We will learn about the pin operator ^ used to access previously bound values. The match operatorWe have used the = operator a couple times to assign variables in Elixir: iex> x = 1 1 iex> x 1In Elixir, the = operator is actually called the match opera

Welcome! This guide will teach you about Elixir fundamentals - the language syntax, how to define modules, the common data structures in the language, and more. This chapter will focus on ensuring that Elixir is installed and that you can successfully run Elixir's Interactive Shell, called IEx. Let's get started. InstallationIf you haven't yet installed Elixir, visit our installation page. Once yo
