https://elixir-lang.org/blog/2024/06/12/elixir-v1-17-0-released/
This release includes type inference of patterns to provide warnings for an initial set of constructs (binaries, maps, and atoms) within the same function. It also includes a new Duration data type to interact with Calendar types, support for Erlang/OTP 27, and many other improvements.
Warnings from gradual set-theoretic types
This release introduces gradual set-theoretic types to infer types from patterns and use them to type check programs, enabling the Elixir compiler to find faults and bugs in codebases without requiring changes to existing software. The underlying principles, theory, and roadmap of our work have been outlined in "The Design Principles of the Elixir Type System" by Giuseppe Castagna, Guillaume Duboc, José Valim.
At the moment, Elixir developers will interact with set-theoretic types only through warnings found by the type system. The current implementation models all data types in the language:
binary()
,integer()
,float()
,pid()
,port()
,reference()
- these types are indivisible. This means both1
and13
get the sameinteger()
type.atom()
- it represents all atoms and it is divisible. For instance, the atom:foo
and:hello_world
are also valid (distinct) types.map()
and structs - maps can be "closed" or "open". Closed maps only allow the specified keys, such as%{key: atom(), value: integer()}
. Open maps support any other keys in addition to the ones listed and their definition starts with...
, such as%{..., key: atom(), value: integer()}
. Structs are closed maps with the__struct__
key.tuple()
,list()
, andfunction()
- currently they are modelled as indivisible types. The next Elixir versions will also introduce fine-grained support to them.We focused on atoms and maps on this initial release as they are respectively the simplest and the most complex types representations, so we can stress the performance of the type system and quality of error messages. Modelling these types will also provide the most immediate benefits to Elixir developers. Assuming there is a variable named
user
, holding a%User{}
struct with anaddress
field, Elixir v1.17 will emit the following warnings at compile-time:Pattern matching against a map or a struct that does not have the given key, such as
%{adress: ...} = user
(noticeaddress
vsadress
)Accessing a key on a map or a struct that does not have the given key, such as
user.adress
Updating a struct or a map that does not define the given key, such as
%{user | adress: ...}
Invoking a function on non-modules, such as
user.address()
Capturing a function on non-modules, such as
&user.address/0
Attempting to invoke to call an anonymous function without an actual function, such as
user.()
Performing structural comparisons with structs, such as
my_date < ~D[2010-04-17]
Performing structural comparisons between non-overlapping types, such as
integer >= string
Building and pattern matching on binaries without the relevant specifiers, such as
<<name>>
(this warns because by default it expects an integer, it should have been<<name::binary>>
instead)Attempting to rescue an undefined exception or a struct that is not an exception
Accessing a field that is not defined in a rescued exception
These new warnings help Elixir developers find bugs earlier and give more confidence when refactoring code, especially around maps and structs. While some of these warnings were emitted in the past, they were discovered using syntax analysis. The new warnings are more reliable, precise, and with better error messages. Keep in mind, however, that the Elixir typechecker only infers types from patterns within the same function at the moment. Analysis from guards and across function boundaries will be added in future relases. For more details, see our new reference document on gradual set-theoretic types.
The type system was made possible thanks to a partnership between CNRS and Remote. The development work is currently sponsored by Fresha, Starfish*, and Dashbit.
Erlang/OTP support
This release adds support for Erlang/OTP 27 and drops support for Erlang/OTP 24. We recommend Elixir developers to migrate to Erlang/OTP 26 or later, especially on Windows. Support for WERL (a graphical user interface for the Erlang terminal on Windows) will be removed in Elixir v1.18.
Adding
Duration
andshift/2
functionsElixir introduces the
Duration
data type and APIs to shift dates, times, and date times by a given duration, considering different calendars and time zones.Note the operation is called
shift
(instead ofadd
) since working with durations does not obey properties such as associativity. For instance, adding one month and then one month does not give the same result as adding two months:Still, durations are essential for building intervals, recurring events, and modelling scheduling complexities found in the world around us. For
DateTime
s, Elixir will correctly deal with time zone changes (such as Daylight Saving Time), but provisions are also available in case you want to surface conflicts (for example, you shifted to a wall clock that does not exist, because the clock has been moved forward by one hour). SeeDateTime.shift/2
for examples.Finally, a new
Kernel.to_timeout/1
function has been added, which helps developers normalize durations and integers to a timeout used by Process APIs. For example, to send a message after one hour, one can now write:v1.17.0 (2024-06-12)

This release adds basic support for Erlang/OTP 26. When migrating
to Erlang/OTP 26, keep it mind it changes how maps are stored
internally and they will be printed and traversed in a different
order (note maps never provided a guarantee of their order).
To aid migration, this release adds

Elixir v1.14 brings many improvements to the debugging experience in Elixir
and data-type inspection. It also includes a new abstraction for easy
partitioning of processes called
PartitionSupervisor
, as well as improvedcompilation times and error messages.
Elixir v1.14 is the last version to support Erlang/OTP 23. Consider updating
to Erlang/OTP 24 or Erlang/OTP 25.
dbg
Kernel.dbg/2
is a new macro that's somewhat similar toIO.inspect/2
, butspecifically tailored for debugging.
When called, it prints the value of whatever you pass to it, plus the debugged
code itself as well as its location. This code:
Prints this:
dbg/2
can do more. It's a macro, so it understands Elixir code. You can seethat when you pass a series of
|>
pipes to it.dbg/2
will print the valuefor every step of the pipeline. This code:
Prints this:
IEx and Prying
dbg/2
supports configurable backends. IEx automatically replaces the defaultbackend by one that halts the code execution with
IEx.Pry
, giving developersthe option to access local variables, imports, and more. This also works with
pipelines: if you pass a series of
|>
pipe calls todbg
(or pipe into it at theend, like
|> dbg()
), you'll be able to step through every line in the pipeline.You can keep the default behaviour by passing the
--no-pry
option to IEx.PartitionSupervisor
PartitionSupervisor
is a new module that implements a new supervisor type. Thepartition supervisor is designed to help with situations where you have a single
supervised process that becomes a bottleneck. If that process's state can be
easily partitioned, then you can use
PartitionSupervisor
to supervise multipleisolated copies of that process running concurrently, each assigned its own
partition.
For example, imagine you have an
ErrorReporter
process that you use to reporterrors to a monitoring service.
As the concurrency of your application goes up, the
ErrorReporter
processmight receive requests from many other processes and eventually become a
bottleneck. In a case like this, it could help to spin up multiple copies of the
ErrorReporter
process under aPartitionSupervisor
.The
PartitionSupervisor
will spin up a number of processes equal toSystem.schedulers_online()
by default (most often one per core). Now, whenrouting requests to
ErrorReporter
processes we can use a:via
tuple androute the requests through the partition supervisor.
Using
self()
as the partitioning key here means that the same process willalways report errors to the same
ErrorReporter
process, ensuring a form ofback-pressure. You can use any term as the partitioning key.
A Common Example
A common and practical example of a good use case for
PartitionSupervisor
ispartitioning something like a
DynamicSupervisor
. When starting many processesunder it, a dynamic supervisor can be a bottleneck, especially if said processes
take a long time to initialize. Instead of starting a single
DynamicSupervisor
,you can start multiple:
Now you start processes on the dynamic supervisor for the right partition.
For instance, you can partition by PID, like in the previous example:
Improved errors on binaries and evaluation
Erlang/OTP 25 improved errors on binary construction and evaluation. These improvements
apply to Elixir as well. Before v1.14, errors when constructing binaries would
often be hard-to-debug generic "argument errors". With Erlang/OTP 25 and Elixir v1.14,
more detail is provided for easier debugging. This work is part of EEP
54.
Before:
Now:
Slicing with steps
Elixir v1.12 introduced stepped ranges, which are ranges where you can
specify the "step":
Stepped ranges are particularly useful for numerical operations involving
vectors and matrices (see Nx, for example).
However, the Elixir standard library was not making use of stepped ranges in its
APIs. Elixir v1.14 starts to take advantage of steps with support for stepped
ranges in a couple of functions. One of them is
Enum.slice/2
:binary_slice/2
(andbinary_slice/3
for completeness) has been added to theKernel
module, that works with bytes and also support stepped ranges:Expression-based inspection and
Inspect
improvementsIn Elixir, it's conventional to implement the
Inspect
protocol for opaquestructs so that they're inspected with a special notation, resembling this:
This is generally done when the struct content or part of it is private and the
%name{...}
representation would reveal fields that are not part of the publicAPI.
The downside of the
#name<...>
convention is that the inspected output is notvalid Elixir code. For example, you cannot copy the inspected output and paste
it into an IEx session.
Elixir v1.14 changes the convention for some of the standard-library structs.
The
Inspect
implementation for those structs now returns a string with a validElixir expression that recreates the struct when evaluated. In the
MapSet
example above, this is what we have now:
The
MapSet.new/1
expression evaluates to exactly the struct that we'reinspecting. This allows us to hide the internals of
MapSet
, while keepingit as valid Elixir code. This expression-based inspection has been
implemented for
Version.Requirement
,MapSet
, andDate.Range
.Finally, we have improved the
Inspect
protocol for structs so thatfields are inspected in the order they are declared in
defstruct
.The option
:optional
has also been added when deriving theInspect
protocol, giving developers more control over the struct representation.
See the updated documentation for
Inspect
for a general rundown onthe approaches and options available.
