This document gives an overview about nvim. The concepts here are also applicable for vim and partially for vi. But I will mostly focus on nvim. But to keep it short and generall i will use vim.
Originally there was vi, then vim came and finally neovim aka. nvim arrivied.
Why am I using in some cases vim?
Basically vim is installed by default on linux and mac - it's everywhere. So whenever we login to a machine we can start wird text editing. My other main reason is that in vim I am more focused. Especially that I not need a mouse and completely navigate via keyboard. This is the so called vim motion. And it's fast.
For me an alternative editor to vim (but with UI) are:
I used that editor's in the past to edit files from various formats. But none of them are fast as vim.
Another thing is that i usually done a lot of things in console. The reason for that are various.
One more thing is when editing text in any kind of program we navigate using usually with arrow keys. Pressing it several times.
Instead of hitting arrow keys several times we can invest time in vim shortcut's like dw - delete word right from cursor.
Now as mentioned vim is by default installed on your machine or server.
By hitting vim in console you are ready to code.
Vim has by default vim has a file explorer netrw.
When enriching with plugins it can even more.
You can even attach a language server (protocoll) so that code completion is possible. But in such cases i use IDE's like intellij or eclipse.
To keep the dependency less I used minimum plugins. The plugins should work for both vim and nvim.
The default vim is enough for editing text but with few plugins and colorscheme vim is more enriched.
Here I give the main plugins I use:
telescope - with this plugin you can filter files in your current working directy. So we can navigate fast in our current working directory.lualine - give you a good overview in status line. Like which vim mode or git branchnvim-treesitter - parses your text as tree and gives you syntax highlighting.To install the plugins I use nvim packer.
A short note here. vim works with .vim files nvim can also understand .lua files.
So when configuring nvim i prefer .lua.
