My personal nvim configuration

I made this public so I can easily clone without authentication,
but since I treat this as a personal use only stuff,
there can be some(read "a lot of") messy stuff.

Much of this might have been selectively copy pasted from plugin repos. Those repos are obviously listed in plugin setup part.

Basic usage of this config

First Time Setup

Installing system stuff (Fedora example):

sudo dnf install \
	python3-pip \
	neovim \
    ripgrep \
    fd-find \
    npm \
    tree-sitter-cli \
    wl-clipboard \
    dejavu-fonts-all \
    gnu-free-mono-fonts \
    clang \
    perl-App-cpanminus # optional, allow perlnavigator lsp working properly

pip install pynvim

git clone --depth 1 https://github.com/wbthomason/packer.nvim\
 ~/.local/share/nvim/site/pack/packer/start/packer.nvim

Inside vim

:PackerInstall
:PackerSync

# installing packages, which mason-lspconfig cannot autoinstall (?)
:MasonInstall phpcs

# tree-sitter setup
:TSInstall html dockerfile cpp css markdown c gitcommit bash phpdoc comment python http php regex json5 lua gitattributes gitignore json git_rebase javascript perl sql yaml

On Fedora there is need to make sure your system can display any unicode character. Hacked fonts are needed for filetype icons but there is also need for a dedicated package with unicode fonts (like unifont-fonts.noarch) that will have every character missing from default font used in Neovim editor.

General info

Mason:

Mason installs stuff in .local/share/nvim/mason/packages so they are independent from system stuff, like pip installed python packages.
