Back in November, during the .NET Conf Microsoft released F# 8.0 as part of the .NET 8 release. The new version of F# brings in many features to make F# code simpler, more uniform, and apps more performant. The new features are related to language changes, improved diagnostics, quality-of-life improvements, and performance boosts for project compilation and upgrades.
In the latest F# release, several noteworthy features have been introduced to enhance the language’s expressiveness and efficiency. One significant addition is the shorthand for defining simple lambda functions, which proves particularly useful for situations where a lambda function is confined to an atomic expression on the lambda argument. This shorthand, expressed as (fun x -> x.Property), simplifies the code, making it more concise and readable.
A second key feature addresses the copy-and-update functionality for nested records. This enhancement simplifies the process of copying and updating nested record fields, providing developers with a more efficient and straightforward approach to field manipulation within records.
The while!(while bang) feature, initially announced in an earlier preview, has been officially integrated. This feature simplifies the use of computation expressions, especially when looping over a boolean condition that needs evaluation within the computation expression, such as within an async block.
let doStuffWithWhileBang =
async
while! asyncCondition do
count <- count + 2
return count
F# 8 also introduces an extended string interpolation syntax, drawing inspiration from C#. This improvement enhances the support for existing interpolated strings in F#. Literal text output can now seamlessly combine with values and expressions by enclosing them in braces . However, to use braces as literal parts of the output, they need to be escaped by doubling (via and ). As stated, this can be helpful when dealing with texts containing numerous braces, such as when embedding other languages in F# strings, like JSON, CSS, or HTML-based templating languages likemustache.
Furthermore, another significant update involves string literals used in built-in printing functions (printfn, sprintfn, etc.). In previous versions, the specified format had to be a string literal typed directly at the usage location. With F# 8, string literals defined elsewhere are now supported. Additionally, developers can define a string literal using a concatenation of existing string literals. This allows for the reuse of commonly repeated format specifiers as patterns, reducing redundancy in the codebase.
[<Literal>]
let formatBody = "(%f,%f)"
[<Literal>]
let formatPrefix = "Person at coordinates"
[<Literal>]
let fullFormat = formatPrefix + formatBody
let renderedCoordinates = sprintf formatBody 0.25 0.75
let renderedText = sprintf fullFormat 0.25 0.75
With this release, F# is experiencing significant enhancements to improve uniformity and consistency. Static members can now be declared and implemented in interfaces, emphasizing concrete members in contrast to F#7’s static abstract members. Additionally, static bindings, including static let and static do, are extended to discriminated unions, records, structs, and types without primary constructors, promoting the encapsulation of data and logic within type definitions.
[<Interface>]
type IDemoable =
abstract member Show: string -> unit
static member AutoFormat(a) = sprintf "%A" a
Also, the try-with code construct is now supported within collection builders, such as seq for IEnumerable definitions, [] for list builders, and [||] for array builders. This extension enables exception handling within these expressions, allowing for various combinations of ‘try’ and ‘with’ scenarios, enhancing the overall clarity and conciseness of F# code.
F# 8 introduces several quality-of-life improvements. One significant improvement is the introduction of trimmability for compiler-generated code, enhancing code clarity and reducing unnecessary elements.
Parser recovery has been refined, contributing to a more robust and resilient parsing process for improved code comprehension. Strict indentation rules have been implemented, promoting consistent code formatting and enhancing readability across F# projects.
Autocomplete functionality has been refined, providing an improved developer experience by offering more accurate and context-aware suggestions during coding. Additionally, [<Struct>] unions now support over 49 cases, expanding the versatility of this construct within F#.
Compiler performance has been a focal point in this release, addressing crucial aspects related to the F# compiler and associated tooling. Special attention has been given to two key areas F# – incremental builds of large graphs of projects via the Reference assemblies feature, and CPU-parallelization of the compiler process.
Overall community feedback about this release, was positive and a couple of community members wrote that they already experienced the performance improvements. A user called David N wrote the following comment on the original blog post announcement:
Brilliant work. It’s taken me a while to get to read this and I see I have several things to go and try out now. Especially the new experimental compiler optimisations. I had already been trying the graph optimisations and they gave a 20% improvement to my project build times just with that one feature.
CHICAGO (AP) — United Airlines has struck a deal with Elon Musk’s SpaceX to offer satellite-based Starlink WiFi service on flights within the next several years.
The airline said Friday the service will be free to passengers.
United said it will begin testing the service early next year and begin offering it on some flights by later in 2025.
Financial details of the deal were not disclosed.
The announcement comes as airlines rush to offer more amenities as a way to stand out when passengers pick a carrier for a trip. United’s goal is to make sitting on a plane pretty much like being on the ground when it comes to browsing the internet, streaming entertainment and playing games.
“Everything you can do on the ground, you’ll soon be able to do on board a United plane at 35,000 feet, just about anywhere in the world,” CEO Scott Kirby said in announcing the deal.
The airline says Starlink will allow passengers to get internet access even over oceans and polar regions where traditional cell or Wi-Fi signals may be weak or missing.
