ccimport

a tiny package for fast python c++ binding build.

support python 3.5, 3.7-3.9.

Usage

Limitations in Code

• Function/class with template parameter aren't supported. If you really need to use template, you need to provide all parameters with a default value. The generated code will use func<> to bind your code.

Single File Extension

• Add CODEAI_EXPORT before your function declaration name. For class, write a static factory member that return a unique_ptr, then add CODEAI_EXPORT_INIT before it.

• use ccimport.autoimport to build extension.

Multiple File Extension

• Add CODEAI_EXPORT and/or CODEAI_EXPORT_INIT in header files.

• Implement functions and classes in source files.

• use ccimport.autoimport to build extension. you need to add all header files with CODEAI_EXPORT to sources parameter.

Library without pybind

• Use ccimport.ccimport instead.
