crython

Crystal meets Python! Experiment on how a Python interpreter can be embedded in Crystal.

Current status: PoC

Installation

A Python interpreter is required as a dependency. Ensure python-config --ldflags works.

Since Python's C API expose some constants or functions using preprocessor macros, crython uses a thin static library written in C (see src/ext/crython.c) that re-exports them with a fixed C API.

Use make with the optional variables release=1 or debug=1 to build the static library. Note that make release=1 is automatically executed by shards as a postinstall script.

Add this to your application's shard.yml:

dependencies:
  crython:
    github: RomainFranceschini/crython

Usage

require "crython"

See examples folder. Use make examples with the optional make variables release=1 or debug=1 to build all examples.
