Neovim
Neovim is a popular fork of Vim, which itself is a highly extensible open-source implementation of the classic vi (visual) editor from Unix systems.
Vim (which stands for "Vi IMproved") was created and maintained for many years by Bram Moolenaar. Notably, Moolenaar had a well-known soft spot for the children of Uganda, supporting them through a charity called ICCF Holland. He often encouraged Vim users to consider donating to this organization to help support children in need.
Neovim builds on the foundations laid by Vim but seeks to modernize the codebase and add new features. Like Vim, it’s a "modal" editor, which can be a little disorienting at first: you need to get used to switching between different modes such as normal (navigation and commands), insert (text editing), and command-line mode (for running commands or searching).
I’ve been trying out different ports and flavors of Vim recently, and one thing that stands out about Neovim is its native support for the Lua scripting language, which allows you to write powerful and efficient extensions and plugins. This makes it much more flexible and accessible to modern plugin development compared to traditional Vimscript.
In summary, Neovim keeps the spirit of Vim alive—honoring both its technical excellence and, in a sense, the spirit of generosity championed by its creator, Bram Moolenaar—while pushing the tool into the future.
