Neovim configs

My neovim configurations

Editors installation

• neovim
• vimr (For external Window Gui)

Prerequisites

The following packages need to be installed

• curl

Installation

1. Clone the repository.

mkdir -p ~/.config/

## Clone the repository to ~/.config/nvim
git clone --depth 1 https://github.com/aswinkarthik93/neovim-dotfiles.git ~/.config/nvim

## Open nvim
nvim

2. Nvim will automatically install Plugins. It will take some time to finish.

• For Installing new plugins, run :PlugInstall within the editor.
• For Updating the plugins, run :PlugUpdate within the editor.
• The default theme is NeoSolarized which is a Solarized dark theme and will work post plugin installation.

3. Post installation if there are issues, use :CheckHealth. Neovim will do a health check and report on what is missing and how to fix it.
