PyCharm 2018.2 Help

Cython Support

Prerequisites

PyCharm provides initial Cython support out-of-the-box. PyCharm recognizes *.pyx, *.pxd, and *.pxi files, and allows you to edit them.

However, if you want to compile and run *.pyx files, make sure that the following prerequisites are met:

  • Cython is downloaded and installed on your computer.

  • C compiler is downloaded and installed on your computer.

Cython support

Cython files are marked with icon cython icon.

Cython support includes:

  1. Coding assistance:
  2. Code inspections. Almost all Python code inspections work for Cython.

  3. Refactorings.

  4. Advanced facilities to search through the source code, in particular, finding usages.

  5. Compiling Cython modules:
    • Compilation is done using external tools. The preferred build systems (Makefile, setup.py, etc.) should be configured as external tools.

    • C compiler should be downloaded and installed on your computer.

  6. Cython debugger. Refer to Cython documentation for details.
