Changelog

0.2.0.0 / 2020-09-30

Added GHC-lib front end and command line option for front end selection
- A front end can be specified with --frontend=FRONTEND or -f FRONTEND.
- Allowed values are: haskell-src-exts, ghc-lib.
- haskell-src-exts is used by default.
Improved error messages
- Added and updated error messages state the cause of many errors more clearly.
- Warnings for skipped unsupported features have been added.
- Most error messages contain input code excerpts showing the location the error occurred.
Added support for module imports
- Regular, qualified and aliased imports between input modules are supported.
- Import specifications (explicitly importing or hiding certain types, constructors or functions) are not supported and skipped.
Source spans are now largely retained during the compilation
- This does not affect the output of the pattern matching compiler, but can be useful when using the compiler as a library.
Various bug fixes

Fixed compile-time warnings
The library and executable can now be compiled with GHC's -Wall and -Werror flags set.
