CHANGES:

  • CLI: passing --eval to melc now works as expected
    (#1040)
  • runtime: add some bindings to Js.Bigint
    (#1044)
  • core: emit throw new Error(..) rather than throwing a JS object with the
    Melange exception payload
    (#1036)
  • stdlib: fix runtime primitive for Float.{min,max} and related functions
    (#1050)
  • core: emit let instead of var in compiled JS
    (#1019)
  • core: in compiled JS, stop generating closures in loops that capture mutable
    variables (#1020)
  • runtime: add bindings to Js.Set
    (#1047)
  • runtime: add minimal bindings for JS iterators (#1060)
  • core: in compiled JS, emit const for variables that Melange knows aren't
    going to be reassigned
    (#1019,
    #1059).
  • runtime: add minimal bindings for JS iterators
    (#1060)
  • core: handle missing .cmj when compiling dune virtual libraries
    (#1067, fixes
    #658)
  • core: print lambda IR after TRMC pass when --drawlambda is passed
    (#1072)
  • core: remove unnecessary internal code from melange-compiler-libs, slimming
    down the melange executable and speeding up the build
    (#1075)
  • core: implement warning 51 in Melange (wrong-tailcall-expectation)
    • This warning had previously been disabled entirely in the typechecker
      version that Melange uses. It becomes more important with TRMC support
      added in Melange 2.1.0.
  • core: accept esm{,-global} in addition to es6{,-global} for
    --mel-module-type; accept --mel-module-system in addition to
    --mel-module-type too
    (#1086).
  • core: upgrade the OCaml type checker version to OCaml 5.2
    (#1074)
  • core: upgrade the Stdlib to match OCaml 5.2's
    (#1078)
  • runtime: add bindings for functions in WeakMap and WeakSet
    (#1058)
  • runtime: add bindings to Js.Map
    (#1101)
  • core: fix a recursive module code generation bug when submodule names inside
    recursive modules are mangled
    (#1111)

CHANGES:

  • BREAKING: remove Belt as a dependency of Stdlib
    (#796,
    #797)
    • Melange no longer includes the melange.belt library by default; after

    • Js.Option: use Stdlib.Option or Belt.Option instead;
    • Js.Result: use Stdlib.Result or Belt.Result instead;
    • Js.Cast.
  • BREAKING:
    • remove support for @bs / @bs.* attributes; Melange users should now

      (#818)

    #965)
    • Modules ending with 2 (e.g. Js.String2, Js.Array2,
      Js.TypedArray2) are no longer available in Melange
    • The functions in their corresponding modules now take labeled arguments
      and one positional argument, prioritizing the usage of |> but still
      allowing |. (-> in Reason) when optionally labeled arguments aren't
      omitted.
  • BREAKING(runtime): remove deprecated functions from Js.* modules
    (#897)
  • Consistently handle empty payloads in externals:
    (#852)

  • Fix error messages related to [@mel.meth] arity mismatches
    (PR)

      derived by the underlying record.

CHANGES:

  • Build executables for bytecode-only platforms too (#596)
  • Move the entire builtin PPX to melange.ppx. Preprocessing with melange.ppx will needed in most cases going forward, as it's responsible for processing external declarations, @deriving attributes and more, compared to the previous release where melange.ppx just processed AST extension nodes (#583)
  • Remove old BuckleScript-style conditional compilation (#605)
  • Don't emit JS import / require paths with foo/./bar.js (#598, #612)
  • Wrap the melange runtime (#624, #637). After this change, Melange exposes fewer toplevel modules. Melange runtime / stdlib modules are now wrapped under:
    • Caml* / Curry modules are part of the runtime and keep being exposed as before
    • Js.* contains all the modules previously accessible via Js_*, e.g. Js_int -> Js.Int
    • Belt.* wraps all the Belt modules; Belt_List etc. are not exposed anymore, but rather nested under Belt, e.g. Belt.List
    • Node.*: we now ship a melange.node library that includes the modules containing Node.js bindings. After this change, users will have to depend on melange.node explicitly in order to use the Node.* modules.
    • Dom.*: we now ship a melange.dom library that includes the modules containing Node.js bindings. After this change, users will have to depend on melange.dom explicitly in order to use the Dom.* module.
  • Disable warning 61 (unboxable-type-in-prim-decl) for externals generated by Melange (#641, #643)
  • Add --rectypes (#644) to enable recursive types
  • [melange.ppx]: Deprecate bs.* attributes in favor of mel.* (#566,
    #662, #663)
  • [melange]: Fix field access code generation when openin inline functor applications (#661, #664)
  • [melange]: Upgrade the OCaml typechecker version to 5.1 (#668)
  • [melange.ppx]: Deprecate [@@mel.val] and suggest its removal. This attribute is redundant and unnecessary (#675, #678)
  • [melange]: remove old, unused CLI flags: -bs-ns, -bs-cmi, -bs-cmj, -bs-no-builtin-ppx, -bs-super-errors (#686).
  • [melange]: generate correct code for types with the option shape (#700).
  • [melange]: stop exporting $$default in the generated JavaScript when using ES6 default exports let default = .. (#708).
  • [melange]: allow exporting invalid OCaml identifiers in the resulting JavaScript with @mel.as (#714, fixes #713).
  • [melange]: Allow using @mel.as in external declarations without explicitly annotating @mel.{string,int} ([#722 (https://github.com//pull/722), fixes #578).
  • [melange]: Allow using @mel.unwrap in external declarations with @mel.obj (#724, fixes #679).
  • [melange]: Support renaming fields in inline records / record extensions with @mel.as (#732, fixes #730).

  • melange: print an error message if $MELANGELIB is set to a directory that
    doesn't exist (#449)
  • melange: fix bug where --bs-module-name didn't always affect generated JS
    file casing (#446)
  • melange: fix bug where -o output.js didn't always write a JavaScript file
    (#454)
  • melange: remove the -bs-read-cmi flag in favor of the builtin
    -intf-suffix flag, standard in OCaml
    (#458,
    #460)
  • melange: return an actionable error message when no output is specified
    with -impl / -intf
    (#465,
    #466)
  • melange: use Object.prototype.hasOwnProperty in the Caml_obj runtime
    (#469)
  • melange: transform
    NonEscapeCharacter
    correctly in JS strings (those written using {js|string here|js})
    (#469)
  • melange: define MELANGE conditional compilation variable
    (#472)
  • melange: Make Pervasives exactly match the Stdlib behavior
    (#476)
  • melange: fix unbound error when trying to use Printexc.exn_slot_id
    (#482)
  • melange: fix codegen issue accessing a nested module path that is also
    included (#487)
  • melange: preserve the correct command-line order for load path directories
    (#492)
  • melange: respect the -nostdlib option; don't add stdlib / runtime to the
    load path in that case
    (#496)
  • melange: build the Melange runtime / stdlib / runtime tests with the dune
    integration (#493). Thus
    melange now requires Dune 3.8.
  • melange: allow shadowing sub-modules of Stdlib in user projects
    (#512)
  • melange, reactjs-jsx-ppx: introduce a reactjs-jsx-ppx package, remove its
    dependency from melange
    (#517)
  • melange: remove the --bs-jsx <version> flag from melc now that
    reactjs-jsx-ppx is a separate package
    (#525)
  • melange: add melpp executable to preprocess #if conditionals with the
    melange parser (#539)
  • mel: delete the mel package. The dune integration is now the only
    officially supported workflow for orchestrating melange builds
    (#546)
  • melange: Extract melange.ppx from the melange package. This preprocessing
    step interprets extensions such as %bs.obj, %bs.raw, %bs.re, etc.
    (#534)
  • melange: allow installing melange in more OCaml versions and compiler
    switches. Melange now migrates binary AST to the version it understands
    (#548)
  • melange: don't run anonymous args function from
    [@@@bs.config {flags = [| ... |]}] attributes
    (#554)
  • melange: add --preamble flag to add a preamble to emitted JS. An example is
    "use client"; in React Server Components, which needs to appear before
    imports (#545,
    #574)
  • melange: turn off warning 20 (ignore-extra-argument) by default. This
    warning is rarely useful in Melange due to false positives when invoking
    functions defined with %bs.raw
    (#488,
    #576)
