Released Version 3.5.5

A major addition in this release is support for the SRFI-1 List Library, which can be loaded using (require-extension (srfi 1)). Note that linear update functions (EG: map!) and circular lists are not supported at this time.

There are many other important changes as well, including:

  • Added a new LispVal type called Opaque for Haskell integration, courtesy of Josh Triplett. The Opaque type allows a native Haskell function to package an arbitrary Haskell type for use by other native code called by husk. See examples/ffi/Opaque.hs for an example of how to use this feature.
  • Implemented file-exists?, delete-file, char-ready?, rationalize, gcd, and lcm.
  • Enhanced the parser to read numbers in scientific notation such as 1e3 and 4.2e1.
  • Modified numerator and denominator to add support for integers and floating point numbers.
  • Fixed a bug in set-cdr! where an unsimplified list may be output. For example, (3 . (2 . (1 . ()))) instead of (3 2 1).
  • Allow apply to receive multiple arguments, as long as the last one is a list.
