post	Released Cyclone Scheme 0.3.4	Cyclone Scheme 0.3.4 is now available.

Features

• Koz Ross added implementations of the following SRFI's:

  • SRFI 28 - Basic format strings
  • SRFI 60 - Integers as bits
  • SRFI 121 - Generators

• Allow a program to have more than one import declaration. A program can now also use cond-expand to selectively expand import declarations.

• Added the -A and -I compiler options from SRFI 138 to cyclone:

  -A directory

  Append directory to the list of directories that are searched in order to locate imported libraries.

  -I directory

  Prepend directory to the list of directories that are searched in order to locate imported libraries.

• Added the -CP, -CE, and -CL compiler options to allow passing arbitrary flags to the C compiler:

-CP cc-commands

Specify a custom command line for the C compiler to compile a program module. See Makefile.config for an example of how to construct such a command line.

-CE cc-commands

Specify a custom command line for the C compiler to compile an executable.

-CL cc-commands

Specify a custom command line for the C compiler to compile a library module.

• Updated the garbage collector to enhance performance for programs with a high allocation rate, and to scale better to multiple concurrent threads.
• Improved error handling by display and write.
• Removed the make_int C macro which was deprecated and could cause problems when used in FFI functions.
• Added a with-handler exception handler form based on the syntax from Bigloo.

Bug Fixes

• Thanks to Koz Ross, equal? has been updated to check bytevectors for deep equality.
• Prevent crashes when allocating large bytevectors.
• Display characters such as #\space correctly when output via write.
• Thanks to Seth Alves, removed unnecessary include of ck_string.h which is not provided in older versions of libck.
