post Released Version 0.2 Release of Cyclone Scheme version 0.2

Today version 0.2 of the Cyclone Scheme-to-C compiler has been released:

http://justinethier.github.io/cyclone/

New features:

  • Added the following libraries from R7RS-large red edition (data structures):
    • SRFI 1 list library
    • SRFI 133 vector library
    • SRFI 111 boxes
    • SRFI 117 mutable queues
    • SRFI 132 sorting library
  • Added SRFI 2, and-let*
  • Added parameterize from section 4.2.6 of R7RS to the (scheme base) library.
  • Added let-values and let*-values to (scheme base).
  • Added infinite?, finite?, and nan? to (scheme inexact).
  • Added string ports to (scheme base) - open-input-string, open-output-string, and get-output-string.
  • Added bytevector ports to (scheme base) - get-output-bytevector, open-input-bytevector, and open-output-bytevector.
  • Modified cyclone to also search the current working directory for built-in headers and libraries.

Bug fixes:

  • Thanks to Mark Meyer, identified and fixed several segfaults in write and display.

  • Updated write to display escaped character sequences (EG: \t) instead of literal characters.

  • Prevent C compilation errors when building a program that only contains basic primitives or a constant at the top level.

  • Fixed the compiler to allow application of a function that can take any number of arguments. For example:

       ((lambda test (write test)) 1 2 3 4)

  • Updated eval to handle functions that take an optional number of arguments.

  • Updated number->string to omit leading zeros for binary conversions.

  • Fixed apply to use the proper semantics when receiving more than one data argument.

  • Changed the assoc and member functions to accept an optional comparison function, and modified both families of functions to be native Scheme functions instead of C primitives.

  • Allow libraries to contain multiple import, begin, and export sections.

Cyclone consists of a compiler and interpreter written entirely in R7RS Scheme, as well as a C runtime. A large portion of the R7RS is supported including libraries, exceptions, continuations, and macros.

Thanks,

Justin
