Cyclone Scheme 0.20
August 14th, 2020
Features
* Added the ability to call Scheme code from C. This includes:
- C function Cyc_scm_call which allows execution of arbitrary
Scheme code, and returns objects that can be safely used by the
caller.
- C function Cyc_scm_call_no_gc. This function imposes more
restrictions but does not register with the Cyclone garbage
collector so there is less overhead.
- Full code examples in the examples/call-scm-from-c directory in the Cyclone source tree.
* Added the -COBJ compiler flag to allow Cyclone to link an executable
using objects that are generated by an external source
such as a makefile.
Cyclone Scheme 0.19
August 3rd, 2020
Features
* Improved error messages with filename and line numbers are now
provided for a wide range of syntax errors.
* Added c-void type into (cyclone foreign).
Bug Fixes
* Fixed a bug in the optimized numeric comparison operators when
comparing a double with a bignum, that could lead to undefined
behavior.
* Fixed make_empty_bytevector and make_c_opaque parameters on
(cyclone foreign).
* Avoid compilation errors when a program ends with a set! expression.
Thanks to Yorick Hardy for the bug report!
* Fixed a bug with the interpreter such that running an import will
no longer remove definitions from the global environment.
* Fixed another interpreter bug to allow import to load renamed
identifiers.
* Prevent compiler errors when calling an anonymous lambda that
accepts an optional argument list.
