calysto_prolog 0.8.3

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](https://github.com/Calysto/metakernel/blob/master/README.rst), 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](https://github.com/Calysto/metakernel/blob/master/metakernel/magics/README.md).

Calysto Scheme in use:

• [CS245: Programming Languages](http://jupyter.cs.brynmawr.edu/hub/dblank/public/CS245%20Programming%20Languages/2014/Programming%20Languages,%20Syllabus.ipynb)

• Videos: https://www.youtube.com/watch?v=2w-iO701g_w

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
