Release Notes: This release includes major improvements to the macro module. In particular, husk now supports arbitrary nesting levels of macro 0-or-many matches and macros now correctly handle improper lists. The parser has also been updated to simplify improper lists. For example, '(1 2 . (3 . ())) will now be converted to (1 2 3).
Release Notes: This release improves R7RS library support, adds support for in-memory I/O buffers, allows "begin" to splice definitions into the enclosing scope, and adds a new commandline option to huski.
Release Notes: This release includes an online User Manual based on R7RS that documents the Scheme and Haskell APIs and explains the Scheme language as implemented by Husk. In addition, many smaller fixes and enhancements are included.
Release Notes: This release improves R7RS support and includes an updated parser that understands Unicode hex values and an expanded set of named characters, cond-expand syntax to statically expand different expressions depending upon whether features are present in the Scheme implementation, and new syntax/functions, including letrec*, syntax-error, include, unless, when, nan?, finite?, infinite?, exact-integer?, exact?, inexact?, square, boolean=?, symbol=?, read-line, flush-output-port, and eof-object. In addition, a library was added to compute simple random numbers.
Release Notes: This release provides many enhancements to improve support for r7rs, including command line flags to start in r7rs mode, r7rs standard libraries, extensions to syntax-rules, and the addition of many procedures to round out the sequence operations.
Release Notes: Significant enhancements have been made to the huski REPL in this release, including support for running Scheme scripts from the shell per SRFI 22 and tab completion for Scheme variables and special forms. This release also includes the (scheme time) library from R7RS and the ability to make system calls from a husk program using the (system) command.
