A very common confusion for new users of Neovim is that their option settings for a particular filetype does not work in init.vim (or init.lua).

In Lua, to pass variable number of arguments, we can use ... (three ellipses) syntax in function argument.

Introduction

In Python, some packages are written mainly or partially in C++, and the Python interfaces are just wrappers around the binary C++ module. Among these packages, there is OpenCV.
