  • v0.18.0.2 Changes

    October 16, 2013

    ๐Ÿ› Bug fixes:

    • โ†ช Regression: Work around a bug in optparse-applicative 0.6 that prevents --strict from being used.
  • v0.18.0.1 Changes

    October 16, 2013
    • Source maps for top level definitions, use --sourcemap

    ๐Ÿ› Bug fixes:

    • Regression: Equality checks for (G)ADTs (deriving Eq)
    • ๐Ÿ›  Fix --strict for top level ADT values (such as module M where g = R)
    • Regression: Serialization in the presence of compression/renaming
    • Pass NoImplicitPrelude (and other enabled extensions) to haskell-names to resolve ambiguities when Prelude isn't imported.


    • โฌ†๏ธ Bump optparse-applicative to 0.6.*
    • โฌ†๏ธ Bump haskell-names to 0.3.1 to allow compilation with Cabal 1.14
    • Ignore more declarations (useful when code sharing with GHC)
  • v0.18.0.0 Changes

    September 24, 2013

    ๐Ÿ†• New features:

    • ๐Ÿ‘Œ Support for qualified imports. Note: You still can't have multiple constructors with the same name in the FFI since the instance field in the serialization is still unqualified.
    • ๐Ÿ‘€ Automatic transcoding now works for functions. See Calling Fay From JavaScript
    • ๐Ÿ‘€ --strict modulename[, ..] generates strict and transcoding wrappers for a module's exports. See Calling Fay From JavaScript
    • --typecheck-only just runs the GHC type checker with the appropriate Fay flags.
    • --runtime-path FILEPATH allows you to supply a custom runtime. Probably only useful for debugging.

    ๐Ÿ› Bug fixes:

    • Don't crash when trying to get the fayToJsFun of an object without
    • ๐Ÿ›  Fixed bug that accidentally flattened list arguments in jsToFay
    • ๐Ÿ›  Fix construction with RecordWildCards not taking already listed fields into account

    ๐Ÿ’ฅ Breaking Changes:

    • ๐Ÿšš Fay.Compiler.Debug has been removed (for now)
    • ๐Ÿšš The interactive compilation mode has been removed (for now)

    Internal changes:

    • Migrated to haskell-src-ext's annotated AST.
    • Name resolution is now done using haskell-names, Fay's name resolution code is now pure and a lot simpler.
  • v0.17.0.0 Changes

    August 27, 2013
    • With the RebindableSyntax and OverloadedStrings extensions Fay will treat Haskell string literals as JavaScript Strings. Add this in all modules and import Fay.Text (from the fay-text package). This is not a breaking change, without these extensions in a module String will be used, as before. All modules can still interoperate normally even if only some of them use this feature. Note that you may have to define fromInteger when using this with Num literals.

    • ๐Ÿ‘ The type signature of Fay.FFI.ffi (in fay) and FFI.ffi (in fay-base) has been generalized to IsString s => s -> a to support RebindableSyntax.

    • Much faster compile time (of the compiler itself) by having the executables depend on the library.

    ๐Ÿ›  Bugfixes:

    • The empty list and unit is now serialized to null when using Automatic (it used to throw an error).


    • Restrict upper bound on language-ecmascript to < 1.0
  • v0.16.0.3 Changes

    August 23, 2013
    • ๐Ÿ‘Œ Support for tuple constructors ((,,) 1,2,3)


    • โฌ†๏ธ Bump pretty-show to >= 1.6
    • โœ‚ Remove the -fdevel flag (when compiling fay itself)
  • v0.16.0.2 Changes

    August 21, 2013


    • โฌ†๏ธ Bump haskell-src-exts to >= 1.14
  • v0.16.0.1 Changes

    August 08, 2013

    ๐Ÿ›  Bugfixes:

    • Allow combining multiline strings with CPP
  • v0.16.0.0 Changes

    August 05, 2013
    • New module generation, modules generate code separately in the format instead of My$Module$foo
    • Transcoding information is also produced separately for each module
    • Removed --naked, --dispatcher, and --no-dispatcher. They are probably not needed anymore
    • Removed Fay$$fayToJsUserDefined and Fay$$jsToFayUserDefined, instead call Fay$$fayToJs and Fay$$jsToFay respectively
    • Escape semi reserved words from Object when printing (constructor -> $constructor). This only matters if you call Fay from JS
    • Automatic now handles lists and tuples (#251)
    • Language.Fay.FFI renamed to Fay.FFI (as before, Fay code can import FFI from fay-base)


    • Print location of parse errors
    • Compile with -XNoImplicitPrelude
    • Support for testing nested modules (module A, module A.B)
    • Bump language-ecmascript to >= 0.15 (new API)
    • Rename/remove some CompileErrors
    • All tests are now included in dist

    ๐Ÿ› Bug fixes:

    • Force cars in string serialization (#306)
  • v0.15.0.0 Changes

    June 08, 2013
    • Expression level FFI calls, ffi "alert('hello!')" :: Fay ()
    • Support let pattern matches
    • Smaller output for serialization code
    • --base-path flag to use a custom base (mainly for fay-prim)
    • Allow ExistentialQuantification, FlexibleContexts, FlexibleInstances, KindSignatures
    • Verify that GADTs using non-record syntax works
    • JS->Fay function serialization
    • Serialization support for (), tuples and Char
    • Add more reserved words for Google Closure

    ๐Ÿ›  Bugfixes:

    • Fix a bug with EModuleContents exports
    • Fix where clause inside pattern guards in function definitions
    • Fix type variables in serialization for multiple constructors
    • Fix EThingAll exports for types with constructors with a different name
    • Don't export types in EThingAll and EThingWith
  • v0.14.5.0 Changes

    April 24, 2013
    • ๐Ÿ‘Œ Support for newtypes (with no runtime cost!)
    • --base-path flag to specify custom locations for fay-base
    • ๐Ÿ›  Fix a bug where imports shadowing local bindings would prevent the local binding from being exported
