purescript v0.7.3 Release Notes

Release Date: 2015-08-13 // over 8 years ago

  • Major Features

    • @gbaz has implemented generic deriving. This allows instances for the Generic class in the purescript-generics package to be derived by the compiler.

    A Generic instance can be derived as follows:

      data Example = Foo String | Bar Int | Baz Boolean

  derive instance genericExample :: Generic Example

    purescript-generics provides examples of usage, such as gShow, gEq and gCompare, for printing, equality tests and comparison respectively.

    See #1138.

    • @garyb has implemented a test for orphan instances which will now cause the build to fail with an error. See #1247

    • ⚠ @mjgpy3 has added a warning when an input glob does not match any files.
