Cython vs Haxelib

Cython is a free compiler for Python and the extended Cython language, used to create C extensions for Python. It translates source code into C or C++ that can be built as Python extension modules. Optional static type declarations can help produce more efficient C, while declared C and C++ types let Python code call existing C or C++ code. Cython supports source-level debugging across Python, Cython and C, and the project describes uses including wrapping external libraries, embedding CPython in applications and speeding up Python code with C modules. It can work with multidimensional NumPy arrays and integrate with low-level libraries and applications. Installation is available through pip, and some scientific Python distributions bundle it. A C compiler is required, with installation guidance for Linux, macOS and Windows. The project describes compatibility with major C and C++ compilers for CPython 3.8 and later, and characterizes PyPy support as mostly usable. Limited API and free-threading CPython support in Cython 3.1 are experimental. Cython is available under the Apache 2.0 License.

Haxelib is the library manager included with Haxe distributions. It connects to a central repository for finding, installing, and sharing Haxe libraries on Windows, macOS, and Linux, with API access. The command line installs the latest release or a specified version, resolves dependencies from HXML files, and supports offline installation. Search matches project names or descriptions, while the info command displays ownership, licensing, descriptions, websites, tags, versions, and release notes. Developers can submit ZIP archives or directories, use Git or Mercurial repositories, and create local repositories from project files. Installed libraries can be exposed to the Haxe compiler with --library or -L. Haxelib can use an HTTP proxy or a custom server. Libraries are distributed as source by default. The public HaxeFoundation repository is MIT licensed, and community links include GitHub, bug reports, Stack Overflow, forums, Discord, and Gitter. All libraries are free.
