0.23.0.0

New features:

  • GHC 7.10 support
  • Add a --pretty-operators flag to replace the escaped operator names with their actual names - By Michal Seweryn
  • Add a --pretty-all flag that enables --pretty, --pretty-operators, and --pretty-thunks - By Michal Seweryn
  • De/serialize type variables as 'automatic'. You no longer have to annotate FFI functions with Automatic, this is now the default. If you need the old behavior, use Ptr. For most existing cases this change shouldn't change anything. - By Zachary Mason

Example output with --pretty-all:

Main.main = new $(function(){
  return _(_(Prelude["$"])(Prelude.print))(_(_(Prelude["++"])(Main.g))(Fay$$list("b")));
});

API changes - By Michal Seweryn:

  • Export CompileResult from Fay.Types
  • Export PrintReader and PrintWriter, and reducing number of PrintState fields (these are moved to PrinterReader and PrintWriter)
  • In the meanwhile PrintWriter field type changed - output is now stored as ShowS - tests run faster now
  • Replace monadic functions (askP, getP, ...) with higher level ones: indented, askIf, newline, write, mapping. askIf is pretty much like previous askP, but works like if-then-else.
  • Internally we are now using ExceptT instead of ErrorT. This fixes deprecation warnings when using transformers 0.4.*.

Bug fixes:

  • Defer automatic_function fayToJs call until after argument application - by Zachary Mason

Dependency bumps:

  • Allow utf8-string 1.0.*
  • Allow time == 1.5.*

0.22.0.0

  • Add a --pretty-thunks flag and compiler option that replaces Fay$$_ and Fay$$$ with _ and $ respectively. Consider this a development flag since it may clash with JS libraries (notably jQuery and underscore)
  • Allow language-ecmascript 0.17.*

0.21.2.1 (2014-11-10)

  • Hide all packages by default when typechecking. This avoids conflicting with packages that haven't been specified on the command-line with --package, e.g. the text package when you import Data.Text.

0.21.2 (2014-10-21)

  • Previously all package imports were ignored, now we only ignore "base" package imports.

0.21.1 (2014-10-21)

  • Lots of additions to in fay-base adding the following modules:
    • Data.Var - Mutable variables, Reactive variables, and reactive signals
    • Unsafe.Coerce
    • Data.Text (fay-text will be updated to reuse this module)
    • Data.Time
    • Data.Ord, Data.Function, Data.Maybe, Data.List, Data.Either
    • Data.Defined and Data.Nullable
    • Data.Mutex - Simple mutexes
    • Control.Exception
    • Data.LocalStorage
    • Data.MutMap - Mutable maps

The introduction of Data.Var required some additions to fay's runtime.

0.21.0.2 (2014-10-19)

  • Fallback to ghc and ghc-pkg in PATH if not available from GHC.Paths

0.21.0.1 (2014-10-12)

  • Update to optparse-applicative == 0.11.*

0.21.0.0 (2014-10-11)

  • Errors are now properly thrown from encodeFay. Changes the type signature to encodeFay :: (GenericQ Value -> GenericQ Value) -> GenericQ Value
  • Update to haskell-src-exts == 1.16.*, This changes the type signature of readerCompileLit to :: S.Sign -> S.Literal -> Compile JsExp
  • Fixes ghc-pkg describe stdout errors not always being printed

0.20.2.0 (2014-09-14)

  • Config option to disable optimizations of newtypes, treating them as normal data types. This can be triggered by setting configOptimizeNewtypes = False or passing --no-optimized-newtypes.

0.20.1.4 (2014-09-04)

  • Update to optparse-applicative == 0.10.*

0.20.1.3 (2014-08-29)

  • Test suite is no longer built by default, cabal install with -ftest to enable.

0.20.1.2 (2014-08-18)

  • Updated homepage URLs, fay-lang.org was 301'd

0.20.1.1 (2014-06-17)

  • Don't cache the main thunk in the generated main call.

0.20.1.0 (2014-06-14)

  • Add default case for UTCTime in Fay.Convert using the aeson instances. Note that this serializes to a json string so you won't be able to deserialize it as a separate type (such as Date) when using Automatic in Fay.

  • Added Fay.Config.defaultConfigWithSandbox that reads the HASKELL_PACKAGE_SANDBOX environment variable. Client libraries can use this instead of manually reading from getEnvironment.

0.20.0.4 (2014-05-23)

  • Allow optparse-applicative 0.9.*

0.20.0.3 (2014-05-09)

  • Allow mtl 2.2.*

0.20.0.2 (2014-05-08)

  • Allow haskell-names 0.4.*

0.20.0.1 (2014-05-08)

  • Allow transformers >= 0.4.1 && < 0.5

0.20.0.0 (2014-04-29)

  • Adds support for LambdaCase and MultiWayIf

  • Modules have moved around a lot and several modules have been un-exposed. From now on you will probably only need to deal with at most Fay (which re-exports a lot of things), Fay.Config, Fay.Types.CompileError, Fay.Convert, and Fay.Types.CompileResult. Please let us know if you would like us to expose more things

  • Config:

    • CompileConfig has been renamed to Config and is now located in Fay.Config.
    • CompileConfig has become a temporary type alias for Config.
    • Fay.Compiler.Config is deprecated, import Fay or Fay.Config instead.
    • The data-default instance for Config is deprecated, use defaultConfig instead.

  • compiling

    • compileFileWithState is deprecated, use compileFileWithResult which returns a Fay.Types.CompileResult instead. As a consequence CompileState is also deprecated from public consumption.
    • compileFile, compileFromToAndGenerateHtml no longer return a triple with the sourcemap, use compileFileWithResult if you want access to this.

  • Importing Fay.Types has been deprecated, import Fay instead.

  • readFromFay has been rewritten using syb instead of pretty-show (Thanks to Michael Sloan and Chris Done)

    • This introduces the following breaking changes:
      • readFromFay has a Data constraint instead of Show.
      • Drops support for Rational and Integer (see below for migration steps). The reason is that neither was serialized in a way that would roundtrip for all values. Also, for similar reasons, fromRational is potentially divergent for aeson's new use of the Scientific type.
    • And adds the following features:
      • You can now write custom Show instances targeting GHC for types shared with Fay.
      • Better performance.
      • Allows the serialization and deserialization to be customized on a per-type basis, via encodeFay and decodeFay.
    • To migrate code using Rational or Integer, use encodeFay and pass an argument e.g. (\f x -> maybe (f x) myIntegerToValueConversion (cast x)) and likewise to decodeFay.

Bugfixes:

  • Mltiple guards on a pattern in a case expression skipped everything but the first guard. To fix this an optimization we had on pattern conditions was disabled.

Dependency bumps:

  • Allow Cabal 1.20 and 1.21

Internal:

  • Test cases are now using tasty instead of test-framework. To run cases in parallel use fay-tests --num-threads=N (see fay-tests --help for more info).
  • Added a test group for desugaring.

0.19.2.1 (2014-04-14)

  • Allow haskell-src-exts 1.15.*

0.19.2 (2014-04-10)

  • Fixes a bug where arrays used with empty data decls would be deserialized into a Fay list instead of kept as is.

0.19.1.2 (2014-04-07)

  • Fix optimizations that were not applied and add codegen test cases.

0.19.1.1 (2014-03-17)

  • Allow optparse-applicative 0.8.*

0.19.1 (2014-03-13)

0.19.0.2 (2014-01-30)

Bugfixes:

  • Don't export transcoding information for fay-base packages when compiling with --no-stdlib
  • Better error messages when forgetting the type signature in an FFI declaration

0.19.0.1 (2014-01-15)

Dependency bumps:

  • Allow aeson 0.7.*

0.19 (2014-01-14)

  • Made import Prelude is implicit, but note that RebindableSyntax implies NoImplicitPrelude.
  • Allow FFI declarations in let and where statements: let f :: X; f = ffi "..." and where f :: X; f = ffi "..."

Bugfixes:

  • Removed extra tag that was generated by --html-wrapper
  • FFI expressions in top level declarations now produce identical code to a normal top level FFI declaration
  • Don't export Data.Ratio and Debug.Trace when using --no-stdlib

Dependency bumps:

  • Allow text 1.1
  • Allow attoparsec 0.11

Note: 0.18.0.1 added source mappings returned by Fay:compileFile and friends meaning it should have been a major bump. Sorry about this!

0.18.1.3 (2013-12-14)

  • Add parsing of Integer to Fay.Convert (note that the runtime doesn't have arbitrary precision Integers)
  • Allow text 1.0.*

0.18.1.2 (2013-11-26)

  • Add support for indirect application of newtypes (such as p = NewType; foo = p x and bar = NewType $ y)

0.18.1.1 (2013-11-22)

  • Fix a bug where records with the same name as top level modules wouldn't be initialized correctly.
  • Fail when using enum syntax on unsupported literal types (for instance ['a'..'z'])

0.18.1 (2013-11-07)

  • Add support for TupleSections

0.18.0.5 (2013-10-28)

Bugfixes:

  • Disallow unsupported patterns in where/let declarations instead of <<loop>>ing on them

Minor:

  • Put upper bounds on all dependencies

0.18.0.4 (2013-10-25)

Bugfixes:

  • Allow // as an operator name (added flag to hse-cpp)
  • Don't transcode function values when using an EmptyDataDecl

0.18.0.3 (2013-10-23)

0.18.0.2 (2013-10-16)

Bug fixes:

  • Regression: Work around a bug in optparse-applicative 0.6 that prevents --strict from being used.

0.18.0.1 (2013-10-16)

  • Source maps for top level definitions, use --sourcemap

Bug fixes:

  • Regression: Equality checks for (G)ADTs (deriving Eq)
  • 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.

Minor:

  • Bump optparse-applicative to 0.6.*
  • Bump haskell-names to 0.3.1 to allow compilation with Cabal 1.14
  • Ignore more declarations (useful when code sharing with GHC)

0.18.0.0 (2013-09-24)

New features:

  • 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.
  • Automatic transcoding now works for functions. See Calling Fay From JavaScript
  • --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.

Bug fixes:

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

Breaking Changes:

  • Fay.Compiler.Debug has been removed (for now)
  • 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.

0.17.0.0 (2013-08-27)

  • 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.

  • 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.

Bugfixes:

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

Minor:

  • Restrict upper bound on language-ecmascript to < 1.0

0.16.0.3 (2013-08-23)

  • Support for tuple constructors ((,,) 1,2,3)

Minor:

  • Bump haskell-src-exts to >= 1.14

0.16.0.1 (2013-08-08)

Bugfixes:

  • Allow combining multiline strings with CPP

0.16.0.0 (2013-08-05)

  • New module generation, modules generate code separately in the format My.Module.foo 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)

Minor:

  • 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

Bug fixes:

  • Force cars in string serialization (#306)

  • Don't export types in EThingAll and EThingWith

0.14.5.0 (2013-04-24)

  • Support for newtypes (with no runtime cost!)
  • --base-path flag to specify custom locations for fay-base
  • Fix a bug where imports shadowing local bindings would prevent the local binding from being exported

0.14.4.0 (2013-04-21)

  • Fix record updates on IE <= 8
  • Import tweaks, will make compilation a lot faster (4x reported) when there are a lot of imports
  • Parse hs sources with base fixities
