Style matters.
[Elixir] has plenty of style but like all languages it can be stifled.
Don't stifle the style.
## About
This is community style guide for the [Elixir programming language][Elixir].
Please feel free to make pull requests and suggestions, and be a part of
Elixir's vibrant community.
If you're looking for other projects to contribute to please see the
[Hex package manager site][Hex].

## Formatting
Elixir v1.6 introduced a [Code Formatter] and [Mix format] task.
The formatter should be preferred for all new projects and source code.
The rules in this section are applied automatically by the code formatter, but
are provided here as examples of the preferred style.
### Whitespace
*
Avoid trailing whitespace.
[[link](#trailing-whitespace)]
*
End each file with a newline.
[[link](#newline-eof)]
*
Use Unix-style line endings (\*BSD/Solaris/Linux/OSX users are covered by
default, Windows users have to be extra careful).
[[link](#line-endings)]
*
If you're using Git you might want to add the following configuration
setting to protect your project from Windows line endings creeping in:
[[link](#autocrlf)]
```sh
git config --global core.autocrlf true
```
*
Limit lines to 98 characters.
Otherwise, set the `:line_length` option in your `.formatter.exs` file.
[[link](#line-length)]
*
Use spaces around operators, after commas, colons and semicolons.
Do not put spaces around matched pairs like brackets, parentheses, etc.
Whitespace might be (mostly) irrelevant to the Elixir runtime, but its proper
use is the key to writing easily readable code.
[[link](#spaces)]
```elixir
sum = 1 + 2
{a, b} = {2, 3}
[first | rest] = [1, 2, 3]
Enum.map(["one", <<"two">>, "three"], fn num -> IO.puts(num) end)
```
*
Do not use spaces after non-word operators that only take one argument; or
around the range operator.
[[link](#no-spaces)]
```elixir
0 - 1 == -1
^pinned = some_func()
5 in 1..10
```
*
Use blank lines between `def`s to break up a function into logical
paragraphs.
[[link](#def-spacing)]
```elixir
def some_function(some_data) do
some_data |> other_function() |> List.first()
end
def some_function do
result
end
def some_other_function do
another_result
end
def a_longer_function do
one
two
three
four
end
```
*
Don't put a blank line after `defmodule`.
[[link](#defmodule-spacing)]
*
If the function head and `do:` clause are too long to fit on the same line, put
`do:` on a new line, indented one level more than the previous line.
[[link](#long-dos)]
```elixir
def some_function([:foo, :bar, :baz] = args),
do: Enum.map(args, fn arg -> arg <> " is on a very long line!" end)
```
When the `do:` clause starts on its own line, treat it as a multiline
function by separating it with blank lines.
```elixir
# not preferred
def some_function([]), do: :empty
def some_function(_),
do: :very_long_line_here
# preferred
def some_function([]), do: :empty
def some_function(_),
do: :very_long_line_here
```
*
Add a blank line after a multiline assignment as a
visual cue that the assignment is 'over'.
[[link](#add-blank-line-after-multiline-assignment)]
```elixir
# not preferred
some_string =
"Hello"
|> String.downcase()
|> String.trim()
another_string <> some_string
# preferred
some_string =
"Hello"
|> String.downcase()
|> String.trim()
another_string <> some_string
```
```elixir
# also not preferred
something =
if x == 2 do
"Hi"
else
"Bye"
end
String.downcase(something)
# preferred
something =
if x == 2 do
"Hi"
else
"Bye"
end
String.downcase(something)
```
*
If a list, map, or struct spans multiple lines, put each element, as well as
the opening and closing brackets, on its own line.
Indent each element one level, but not the brackets.
[[link](#multiline-enums)]
```elixir
# not preferred
[:first_item, :second_item, :next_item,
:final_item]
# preferred
[
:first_item,
:second_item,
:next_item,
:final_item
]
```
*
When assigning a list, map, or struct, keep the opening bracket on the same
line as the assignment.
[[link](#multiline-list-assign)]
```elixir
# not preferred
list =
[
:first_item,
:second_item
]
# preferred
list = [
:first_item,
:second_item
]
```
*
If any `case` or `cond` clause needs more than one line (due to line length,
multiple expressions in the clause body, etc.), use multi-line syntax for all
clauses, and separate each one with a blank line.
[[link](#multiline-case-clauses)]
```elixir
# not preferred
case arg do
true -> IO.puts("ok"); :ok
false -> :error
end
# not preferred
case arg do
true ->
IO.puts("ok")
:ok
false -> :error
end
# preferred
case arg do
true ->
IO.puts("ok")
:ok
false ->
:error
end
```
*
Place comments above the line they comment on.
[[link](#comments-above-line)]
```elixir
String.first(some_string) # not preferred
# preferred
String.first(some_string)
```
*
Use one space between the leading `#` character of the comment and the text of
the comment.
[[link](#comment-leading-spaces)]
```elixir
#not preferred
String.first(some_string)
# preferred
String.first(some_string)
```
### Indentation
*
Indent and align successive `with` clauses.
Put the `do:` argument on a new line, aligned with the previous clauses.
[[link](#with-clauses)]
```elixir
with {:ok, foo} <- fetch(opts, :foo),
{:ok, my_var} <- fetch(opts, :my_var),
do: {:ok, foo, my_var}
```
*
If the `with` expression has a `do` block with more than one line, or has an
`else` option, use multiline syntax.
[[link](#with-else)]
```elixir
with {:ok, foo} <- fetch(opts, :foo),
{:ok, my_var} <- fetch(opts, :my_var) do
{:ok, foo, my_var}
else
:error ->
{:error, :bad_arg}
end
```
### Parentheses
*
Use parentheses for one-arity functions when using the pipe operator (`|>`).
[[link](#parentheses-pipe-operator)]
```elixir
# not preferred
some_string |> String.downcase |> String.trim
# preferred
some_string |> String.downcase() |> String.trim()
```
*
Never put a space between a function name and the opening parenthesis.
[[link](#function-names-with-parentheses)]
```elixir
# not preferred
f (3 + 2)
# preferred
f(3 + 2)
```
*
Use parentheses in function calls, especially inside a pipeline.
[[link](#function-calls-and-parentheses)]
```elixir
# not preferred
f 3
# preferred
f(3)
# not preferred and parses as rem(2, (3 |> g)), which is not what you want.
2 |> rem 3 |> g
# preferred
2 |> rem(3) |> g()
```
*
Omit square brackets from keyword lists whenever they are optional.
[[link](#keyword-list-brackets)]
```elixir
# not preferred
some_function(foo, bar, [a: "baz", b: "qux"])
# preferred
some_function(foo, bar, a: "baz", b: "qux")
```
## The Guide
The rules in this section may not be applied by the code formatter, but they are
generally preferred practice.
### Expressions
*
Run single-line `def`s that match for the same function together, but separate
multiline `def`s with a blank line.
[[link](#single-line-defs)]
```elixir
def some_function(nil), do: {:error, "No Value"}
def some_function([]), do: :ok
def some_function([first | rest]) do
some_function(rest)
end
```
*
If you have more than one multiline `def`, do not use single-line `def`s.
[[link](#multiple-function-defs)]
```elixir
def some_function(nil) do
{:error, "No Value"}
end
def some_function([]) do
:ok
end
def some_function([first | rest]) do
some_function(rest)
end
def some_function([first | rest], opts) do
some_function(rest, opts)
end
```
*
Use the pipe operator to chain functions together.
[[link](#pipe-operator)]
```elixir
# not preferred
String.trim(String.downcase(some_string))
# preferred
some_string |> String.downcase() |> String.trim()
# Multiline pipelines are not further indented
some_string
|> String.downcase()
|> String.trim()
# Multiline pipelines on the right side of a pattern match
# should be indented on a new line
sanitized_string =
some_string
|> String.downcase()
|> String.trim()
```
While this is the preferred method, take into account that copy-pasting
multiline pipelines into IEx might result in a syntax error, as IEx will
evaluate the first line without realizing that the next line has a pipeline.
To avoid this, you can wrap the pasted code in parentheses.
*
Avoid using the pipe operator just once.
[[link](#avoid-single-pipelines)]
```elixir
# not preferred
some_string |> String.downcase()
System.version() |> Version.parse()
# preferred
String.downcase(some_string)
Version.parse(System.version())
```
*
Use _bare_ variables in the first part of a function chain.
[[link](#bare-variables)]
```elixir
# not preferred
String.trim(some_string) |> String.downcase() |> String.codepoints()
# preferred
some_string |> String.trim() |> String.downcase() |> String.codepoints()
```
*
Use parentheses when a `def` has arguments, and omit them when it doesn't.
[[link](#fun-def-parentheses)]
```elixir
# not preferred
def some_function arg1, arg2 do
# body omitted
end
def some_function() do
# body omitted
end
# preferred
def some_function(arg1, arg2) do
# body omitted
end
def some_function do
# body omitted
end
```
*
Use `do:` for single line `if/unless` statements.
[[link](#do-with-single-line-if-unless)]
```elixir
# preferred
if some_condition, do: # some_stuff
```
*
Never use `unless` with `else`.
Rewrite these with the positive case first.
[[link](#unless-with-else)]
```elixir
# not preferred
unless success do
IO.puts('failure')
else
IO.puts('success')
end
# preferred
if success do
IO.puts('success')
else
IO.puts('failure')
end
```
*
Use `true` as the last condition of the `cond` special form when you need a
clause that always matches.
[[link](#true-as-last-condition)]
```elixir
# not preferred
cond do
1 + 2 == 5 ->
"Nope"
1 + 3 == 5 ->
"Uh, uh"
:else ->
"OK"
end
# preferred
cond do
1 + 2 == 5 ->
"Nope"
1 + 3 == 5 ->
"Uh, uh"
true ->
"OK"
end
```
*
Use parentheses for calls to functions with zero arity, so they can be
distinguished from variables.
Starting in Elixir 1.4, the compiler will warn you about
locations where this ambiguity exists.
[[link](#parentheses-and-functions-with-zero-arity)]
```elixir
defp do_stuff, do: ...
# not preferred
def my_func do
# is this a variable or a function call?
do_stuff
end
# preferred
def my_func do
# this is clearly a function call
do_stuff()
end
```
### Naming
This guide follows the [Naming Conventions] from the Elixir docs,
including the use of `snake_case` and `CamelCase` to describe the casing
rules.
*
Use `snake_case` for atoms, functions and variables.
[[link](#snake-case)]
```elixir
# not preferred
:"some atom"
:SomeAtom
:someAtom
someVar = 5
def someFunction do
...
end
# preferred
:some_atom
some_var = 5
def some_function do
...
end
```
*
Use `CamelCase` for modules (keep acronyms like HTTP, RFC, XML uppercase).
[[link](#camel-case)]
```elixir
# not preferred
defmodule Somemodule do
...
end
defmodule Some_Module do
...
end
defmodule SomeXml do
...
end
# preferred
defmodule SomeModule do
...
end
defmodule SomeXML do
...
end
```
*
Functions that return a boolean (`true` or `false`) should be named
with a trailing question mark.
[[link](#predicate-function-trailing-question-mark)]
```elixir
def cool?(var) do
String.contains?(var, "cool")
end
```
*
Boolean checks that can be used in guard clauses should be named with
an `is_` prefix.
For a list of allowed expressions, see the [Guard][Guard Expressions] docs.
[[link](#predicate-function-is-prefix)]
```elixir
defguard is_cool(var) when var == "cool"
defguard is_very_cool(var) when var == "very cool"
```
*
Private functions should not have the same name as public functions.
Also, the `def name` and `defp do_name` pattern is discouraged.
Usually one can try to find more descriptive names focusing on the differences.
[[link](#private-functions-with-same-name-as-public)]
```elixir
def sum(list), do: sum_total(list, 0)
# private functions
defp sum_total([], total), do: total
defp sum_total([head | tail], total), do: sum_total(tail, head + total)
```
### Comments
*
Write expressive code and try to convey your program's intention through
control-flow, structure and naming.
[[link](#expressive-code)]
*
Comments longer than a word are capitalized, and sentences use punctuation.
Use [one space][Sentence Spacing] after periods.
[[link](#comment-grammar)]
```elixir
# not preferred
# these lowercase comments are missing punctuation
# preferred
# Capitalization example
# Use punctuation for complete sentences.
```
*
Limit comment lines to 100 characters.
[[link](#comment-line-length)]
#### Comment Annotations
*
Annotations should usually be written on the line immediately above the
relevant code.
[[link](#annotations)]
*
The annotation keyword is uppercase, and is followed by a colon and a space,
then a note describing the problem.
[[link](#annotation-keyword)]
```elixir
# TODO: Deprecate in v1.5.
def some_function(arg), do: {:ok, arg}
```
*
In cases where the problem is so obvious that any documentation would be
redundant, annotations may be left with no note.
This usage should be the exception and not the rule.
[[link](#exceptions-to-annotations)]
```elixir
start_task()
# FIXME
Process.sleep(5000)
```
*
Use `TODO` to note missing features or functionality that should be added at a
later date.
[[link](#todo-notes)]
*
Use `FIXME` to note broken code that needs to be fixed.
[[link](#fixme-notes)]
*
Use `OPTIMIZE` to note slow or inefficient code that may cause performance
problems.
[[link](#optimize-notes)]
*
Use `HACK` to note code smells where questionable coding practices were used
and should be refactored away.
[[link](#hack-notes)]
*
Use `REVIEW` to note anything that should be looked at to confirm it is
working as intended.
For example: `REVIEW: Are we sure this is how the client does X currently?`
[[link](#review-notes)]
*
Use other custom annotation keywords if it feels appropriate, but be sure to
document them in your project's `README` or similar.
[[link](#custom-keywords)]
### Modules
*
Use one module per file unless the module is only used internally by another
module (such as a test).
[[link](#one-module-per-file)]
*
Use `snake_case` file names for `CamelCase` module names.
[[link](#underscored-filenames)]
```elixir
# file is called some_module.ex
defmodule SomeModule do
end
```
*
Represent each level of nesting within a module name as a directory.
[[link](#module-name-nesting)]
```elixir
# file is called parser/core/xml_parser.ex
defmodule Parser.Core.XMLParser do
end
```
*
List module attributes, directives, and macros in the following order:
[[link](#module-attribute-ordering)]
1. `@moduledoc`
1. `@behaviour`
1. `use`
1. `import`
1. `require`
1. `alias`
1. `@module_attribute`
1. `defstruct`
1. `@type`
1. `@callback`
1. `@macrocallback`
1. `@optional_callbacks`
1. `defmacro`, `defmodule`, `defguard`, `def`, etc.
Add a blank line between each grouping, and sort the terms (like module names)
alphabetically.
Here's an overall example of how you should order things in your modules:
```elixir
defmodule MyModule do
@moduledoc """
An example module
"""
@behaviour MyBehaviour
use GenServer
import Something
import SomethingElse
require Integer
alias My.Long.Module.Name
alias My.Other.Module.Example
@module_attribute :foo
@other_attribute 100
defstruct [:name, params: []]
@type params :: [{binary, binary}]
@callback some_function(term) :: :ok | {:error, term}
@macrocallback macro_name(term) :: Macro.t()
@optional_callbacks macro_name: 1
@doc false
defmacro __using__(_opts), do: :no_op
@doc """
Determines when a term is `:ok`. Allowed in guards.
"""
defguard is_ok(term) when term == :ok
@impl true
def init(state), do: {:ok, state}
# Define other functions here.
end
```
*
Use the `__MODULE__` pseudo variable when a module refers to itself. This
avoids having to update any self-references when the module name changes.
[[link](#module-pseudo-variable)]
```elixir
defmodule SomeProject.SomeModule do
defstruct [:name]
def name(%__MODULE__{name: name}), do: name
end
```
*
If you want a prettier name for a module self-reference, set up an alias.
[[link](#alias-self-referencing-modules)]
```elixir
defmodule SomeProject.SomeModule do
alias __MODULE__, as: SomeModule
defstruct [:name]
def name(%SomeModule{name: name}), do: name
end
```
*
Avoid repeating fragments in module names and namespaces.
This improves overall readability and
eliminates [ambiguous aliases][Conflicting Aliases].
[[link](#repetitive-module-names)]
```elixir
# not preferred
defmodule Todo.Todo do
...
end
# preferred
defmodule Todo.Item do
...
end
```
### Documentation
Documentation in Elixir (when read either in `iex` with `h` or generated with
[ExDoc]) uses the [Module Attributes] `@moduledoc` and `@doc`.
*
Always include a `@moduledoc` attribute in the line right after `defmodule` in
your module.
[[link](#moduledocs)]
```elixir
# not preferred
defmodule AnotherModule do
use SomeModule
@moduledoc """
About the module
"""
...
end
# preferred
defmodule AThirdModule do
@moduledoc """
About the module
"""
use SomeModule
...
end
```
*
Use `@moduledoc false` if you do not intend on documenting the module.
[[link](#moduledoc-false)]
```elixir
defmodule SomeModule do
@moduledoc false
...
end
```
*
Separate code after the `@moduledoc` with a blank line.
[[link](#moduledoc-spacing)]
```elixir
# not preferred
defmodule SomeModule do
@moduledoc """
About the module
"""
use AnotherModule
end
# preferred
defmodule SomeModule do
@moduledoc """
About the module
"""
use AnotherModule
end
```
*
Use heredocs with markdown for documentation.
[[link](#heredocs)]
```elixir
# not preferred
defmodule SomeModule do
@moduledoc "About the module"
end
defmodule SomeModule do
@moduledoc """
About the module
Examples:
iex> SomeModule.some_function
:result
"""
end
# preferred
defmodule SomeModule do
@moduledoc """
About the module
## Examples
iex> SomeModule.some_function
:result
"""
end
```
### Typespecs
Typespecs are notation for declaring types and specifications, for
documentation or for the static analysis tool Dialyzer.
Custom types should be defined at the top of the module with the other
directives (see [Modules](#modules)).
*
Place `@typedoc` and `@type` definitions together, and separate each
pair with a blank line.
[[link](#typedocs)]
```elixir
defmodule SomeModule do
@moduledoc false
@typedoc "The name"
@type name :: atom
@typedoc "The result"
@type result :: {:ok, term} | {:error, term}
...
end
```
*
If a union type is too long to fit on a single line, put each part of the
type on a separate line, indented one level past the name of the type.
[[link](#union-types)]
```elixir
# not preferred
@type long_union_type ::
some_type | another_type | some_other_type | one_more_type | a_final_type
# preferred
@type long_union_type ::
some_type
| another_type
| some_other_type
| one_more_type
| a_final_type
```
*
Name the main type for a module `t`, for example: the type specification for a
struct.
[[link](#naming-main-types)]
```elixir
defstruct [:name, params: []]
@type t :: %__MODULE__{
name: String.t() | nil,
params: Keyword.t()
}
```
*
Place specifications right before the function definition,
after the `@doc`,
without separating them by a blank line.
[[link](#spec-spacing)]
```elixir
@doc """
Some function description.
"""
@spec some_function(term) :: result
def some_function(some_data) do
{:ok, some_data}
end
```
### Structs
*
Use a list of atoms for struct fields that default to `nil`, followed by the
other keywords.
[[link](#nil-struct-field-defaults)]
```elixir
# not preferred
defstruct name: nil, params: nil, active: true
# preferred
defstruct [:name, :params, active: true]
```
*
Omit square brackets when the argument of a `defstruct` is a keyword list.
[[link](#struct-def-brackets)]
```elixir
# not preferred
defstruct [params: [], active: true]
# preferred
defstruct params: [], active: true
# required - brackets are not optional, with at least one atom in the list
defstruct [:name, params: [], active: true]
```
*
If a struct definition spans multiple lines, put each element on its own line,
keeping the elements aligned.
[[link](#multiline-structs)]
```elixir
defstruct foo: "test",
bar: true,
baz: false,
qux: false,
quux: 1
```
If a multiline struct requires brackets, format it as a multiline list:
```elixir
defstruct [
:name,
params: [],
active: true
]
```
### Exceptions
*
Make exception names end with a trailing `Error`.
[[link](#exception-names)]
```elixir
# not preferred
defmodule BadHTTPCode do
defexception [:message]
end
defmodule BadHTTPCodeException do
defexception [:message]
end
# preferred
defmodule BadHTTPCodeError do
defexception [:message]
end
```
*
Use lowercase error messages when raising exceptions, with no trailing
punctuation.
[[link](#lowercase-error-messages)]
```elixir
# not preferred
raise ArgumentError, "This is not valid."
# preferred
raise ArgumentError, "this is not valid"
```
### Collections
*
Always use the special syntax for keyword lists.
[[link](#keyword-list-syntax)]
```elixir
# not preferred
some_value = [{:a, "baz"}, {:b, "qux"}]
# preferred
some_value = [a: "baz", b: "qux"]
```
*
Use the shorthand key-value syntax for maps when all of the keys are atoms.
[[link](#map-key-atom)]
```elixir
# not preferred
%{:a => 1, :b => 2, :c => 0}
# preferred
%{a: 1, b: 2, c: 3}
```
*
Use the verbose key-value syntax for maps if any key is not an atom.
[[link](#map-key-arrow)]
```elixir
# not preferred
%{"c" => 0, a: 1, b: 2}
# preferred
%{:a => 1, :b => 2, "c" => 0}
```
### Strings
*
Match strings using the string concatenator rather than binary patterns:
[[link](#strings-matching-with-concatenator)]
```elixir
# not preferred
<<"my"::utf8, _rest::bytes>> = "my string"
# preferred
"my" <> _rest = "my string"
```
### Regular Expressions
_No guidelines for regular expressions have been added yet._
### Metaprogramming
*
Avoid needless metaprogramming.
[[link](#avoid-metaprogramming)]
### Testing
*
When writing [ExUnit] assertions, put the expression being tested to the left
of the operator, and the expected result to the right, unless the assertion is
a pattern match.
[[link](#testing-assert-order)]
```elixir
# preferred
assert actual_function(1) == true
# not preferred
assert true == actual_function(1)
# required - the assertion is a pattern match
assert {:ok, expected} = actual_function(3)
```
## Resources
### Alternative Style Guides
* [Aleksei Magusev's Elixir Style Guide](https://github.com/lexmag/elixir-style-guide#readme)
— An opinionated Elixir style guide stemming from the coding style practiced
