nvim_config

An efficient neovim config for programmers and academics.

Installation

I usually clone the project and create a symbolic link from ${HOME}/.config/nvim to the nvim_config directory. Doing so, every time nvim_config is updated with git pull, there is no need to re-install it.

When the files are deployed as explained above, the first start of neovim will load and install all the plugins. This procedure can take some time depending on your machine and internet speed connection. On my machine, it takes less than a minute anyway.

Then you will notice that Treesitter installs all the required languages grammars and Mason will install the required language servers. If you need to check the language servers or install more, call :Mason in neovim.

Simple installation procedure

cd
git clone https://github.com/yimyom/nvim_config
mkdir -p ~/.config/
ln -s ~/nvim_config .nvim

Of course, you might want to put the git repository somewhere else. In that case, you need to adapt the paths in the litle script above.

Directory structure

• init.lua: set the basic parameters, load lazy.vim the plugins manager
• lua/ contains config files and the plugins directory.
• lua/plugins: config files for all the neovim plugins

Vi configuration

• Install lazy package manager automatically
• Folding is done using Treesitter expressions
• Tabs are 4 spaces with smart indent
• When opening a terminal, the terminal becomes active immediately. Same when moving the cursor into an active terminal. Use esc to go back to normal mode from a terminal

About the plugins

Color schemes

• catpuccin is the default
• tokyonight
• sonokai
• everforest

To change the default colorscheme, go to the file lua/plugins/ui.lua, search for lines containing vim.cmd.colorscheme and uncomment the one you want to use by default. Make sure all the other lines containing the same string and commented out.

Languages support

Extra configuration's files

R Language

In the dotfiles directory, there is a file called .lintr which need to be placed in your home directory. It contains extra configuration for the R linter to avoid having too many messages on the screen. Depending on your preferences you might want to change this file.

I recommend linking the file directly from the git repository so that next time I update it, you can simply do git pull to get the latest version and everything will be update for you.

Let's assume the git repository is in ${HOME}/nvim_config:

ln -s ${HOME}/nvim_config/dotfiles/.lintr ${HOME}

Next, to have a more advanced configuration, refer to the lintr documentation.
