Published by cknitt over 1 year ago

🚀 New Feature

rescript-compiler - 11.0.0-alpha.1

Published by cknitt over 1 year ago

🚀 Main New Features

Introduce experimental uncurried mode. For experimentation only. PR #5796
Customization of runtime representation of variants and introduction of untagged variants PR #6095, PR #6103

🚀 New Feature

Add support for uncurried mode: a mode where everything is considered uncurried, whether with or without the .. This can be turned on with @@uncurried locally in a file. For project-level configuration in bsconfig.json, there's a boolean config "uncurried", which propagates to dependencies, to turn on uncurried mode.
Since there's no syntax for partial application in this new mode, introduce @res.partial foo(x) to express partial application. This is temporary and will later have some surface syntax.
Make uncurried functions a subtype of curried functions, and allow application for uncurried functions.
The make function of components is generated as an uncurried function.
Use best effort to determine the config when formatting a file.
https://github.com/rescript-lang/rescript-compiler/pull/5968 https://github.com/rescript-lang/rescript-compiler/pull/6080 https://github.com/rescript-lang/rescript-compiler/pull/6086 https://github.com/rescript-lang/rescript-compiler/pull/6087
Customization of runtime representation of variants. This is work in progress. E.g. some restrictions on the input. See comments of the form "TODO: put restriction on the variant definitions allowed, to make sure this never happens". https://github.com/rescript-lang/rescript-compiler/pull/6095
Introduce untagged variants https://github.com/rescript-lang/rescript-compiler/pull/6103
Add support for unary uncurried pipe in uncurried mode https://github.com/rescript-lang/rescript-compiler/pull/5804
Add support for partial application of uncurried functions: with uncurried application one can provide a
subset of the arguments, and return a curried type with the remaining ones https://github.com/rescript-lang/rescript-compiler/pull/5805
Add support for uncurried externals https://github.com/rescript-lang/rescript-compiler/pull/5815 https://github.com/rescript-lang/rescript-compiler/pull/5819 https://github.com/rescript-lang/rescript-compiler/pull/5830 https://github.com/rescript-lang/rescript-compiler/pull/5894
Parser/Printer: unify uncurried functions of arity 0, and of arity 1 taking unit. There's now only arity 1 in the source language. https://github.com/rescript-lang/rescript-compiler/pull/5825
Add support for default arguments in uncurried functions https://github.com/rescript-lang/rescript-compiler/pull/5835

GenType: add support for @genType annotations on module definitions. https://github.com/rescript-lang/rescript-compiler/pull/6113
Prebuilt binaries are now provided for all major platforms:
- macOS x64
- macOS ARM
- Linux x64 (statically linked)
- Linux ARM (statically linked)
- Windows x64

💥 Breaking Change

Remove support for the legacy Reason syntax. Existing Reason code can be converted to ReScript syntax using ReScript 9 as follows:
- npm i -g rescript@9
- rescript convert <reason files>
Remove obsolete built-in project templates and the "rescript init" functionality. This is replaced by create-rescript-app which is maintained separately.
Do not attempt to build ReScript from source on npm postinstall for platforms without prebuilt binaries anymore.
Made pinned dependencies transitive: if a is a pinned dependency of b and b is a pinned dependency of c, then a is implicitly a pinned dependency of c. This change is only breaking if your build process assumes non-transitivity.
Curried after uncurried is not fused anymore: (. x) => y => 3 is not equivalent to (. x, y) => 3 anymore. It's instead equivalent to (. x) => { y => 3 }.
Also, (. int) => string => bool is not equivalen to (. int, string) => bool anymore.
These are only breaking changes for unformatted code.
Exponentiation operator ** is now right-associative. 2. ** 3. ** 2. now compile to Math.pow(2, Math.pow(3, 2)) and not anymore Math.pow(Math.pow(2, 3), 2). Parentheses can be used to change precedence.
Remove unsafe j`$(a)$(b)` interpolation deprecated in compiler version 10 https://github.com/rescript-lang/rescript-compiler/pull/6068

@deriving(jsConverter) not supported anymore for variant types https://github.com/rescript-lang/rescript-compiler/pull/6088
New representation for variants, where the tag is a string instead of a number. https://github.com/rescript-lang/rescript-compiler/pull/6088
GenType: removed support for @genType.as for records and variants which has become unnecessary. Use the language's @as instead to channge the runtime representation without requiring any runtime conversion during FFI. https://github.com/rescript-lang/rescript-compiler/pull/6099 https://github.com/rescript-lang/rescript-compiler/pull/6101

Published by cknitt over 1 year ago

🚀 New Feature

Add experimental suppport for directives. An annotation such as @@directive("use client;") emits use client; verbatim before imports https://github.com/rescript-lang/rescript-compiler/pull/5999
genType: add Core standard library support for the following builtin types: Null.t, Nullable.t, Undefined.t, Dict.t<_>, Promise.t<_>, Date.t, BigInt.t, RegExp.t, Map.t<_, _>, WeakMap.t<_, _>, Set<_>, WeakSet<_> https://github.com/rescript-lang/rescript-compiler/pull/6024

💥 Breaking Change

genType: streamline the treatment of optionals as undefined https://github.com/rescript-lang/rescript-compiler/pull/6024
- Represent option<t> as undefined | t instead of null | undefined | t. This is more permissive when importing functions taking optional values (allows to use option types), but stricter when e.g. exporting ReScript functions taking arguments of option type. Fallback: use Js.undefined<_> instead.
- Represent {x:option<string>} as {x:(undefined | string)} instead of {x?: string}. This is more in line with TS's behaviour. Fallback: use {x?:string}.
