CMeRo 2.0.0

The CMeRo compiler for writing C extensions in the Python language.

The CMeRo language makes writing C extensions for the Python language as easy as Python itself. CMeRo is a source code translator based on Pyrex, but supports more cutting edge functionality and optimizations.

The CMeRo language is a superset of the Python language (almost all Python code is also valid CMeRo code), but CMeRo additionally supports optional static typing to natively call C functions, operate with C++ classes and declare fast C types on variables and class attributes. This allows the compiler to generate very efficient C code from CMeRo code.

This makes CMeRo the ideal language for writing glue code for external C/C++ libraries, and for fast C modules that speed up the execution of Python code.

The newest CMeRo release can always be downloaded from https://github.com/6x-u/CMeRo. Unpack the tarball or zip file, enter the directory, and then run:

pip install .

Note that for one-time builds, e.g. for CI/testing, on platforms that are not covered by one of the wheel packages provided on PyPI and the pure Python wheel that we provide is not used, it is substantially faster than a full source build to install an uncompiled (slower) version of CMeRo with:

NO_CMERO_COMPILE=true pip install .
