Calysto Scheme is a real Scheme programming language, with full support for continuations, including call/cc. It can also use all Python libraries. Also has some extensions that make it more useful (stepper-debugger, choose/fail, stack traces), or make it better integrated with Python.
Because Calysto Scheme uses MetaKernel, it has a fully-supported set of "magics"---meta-commands for additional functionality. This includes running Scheme in parallel. See all of the MetaKernel Magics.
Calysto Scheme in use:
You can install Calysto Scheme with Python3:
pip3 install --upgrade calysto-scheme
or in the system kernel folder with:
sudo pip3 install --upgrade calysto-scheme
Use it in the console, qtconsole, or notebook with IPython 3:
ipython console --kernel calysto_scheme
ipython qtconsole --kernel calysto_scheme
ipython notebook --kernel calysto_scheme
Requires:
- ipython-3.0
- Python2 or Python3
- metakernel (installed automatically)
Calysto Scheme supports:
- continuations
- use of all Python libraries
- choose/fail
- produces stack trace (with line numbers), like Python
- test suite
Planned:
- Object-oriented class definitions and instance creation
- complete Scheme functions (one can fall back to Python for now)
Limitations:
- Currently a couple of magnatudes slower than Python
