Cython Language Extension for VS Code

Features

• Syntax highlighting
• Static syntax checking for C and CPP syntax
• Go to definitions
• Import resolver for .pyx and .pxd files

About

This extension provides syntax highlighting and a Static Syntax checker for the Cython language. Cython is a superset of Python with it's own C-styled syntax mixed with Python syntax.

The static checker is based on Pyright and will only support Cython/Python syntax version 3.0 and above.

This extension uses the configured Python interpreter/venv path from the VS Code Python extension.

Limitations

These features would be nice to have but are not implemented.

• In-depth type analysis
• C headers analysis / inline C code analysis

FAQ

• If no problems are reported will my code compile?
