# 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

Repo: [https://github.com/Szwendacz99/nvim](https://github.com/Szwendacz99/nvim)

### First Time Setup

Installing system stuff (Fedora example):

```bash
sudo dnf install \
	neovim \
    ripgrep \
    fd-find \
    nodejs-bash-language-server \
    tree-sitter-cli \
    wl-clipboard \
    unifont-fonts.noarch

pip install \
	pynvim \
    'pylama[all]' \
    flake8 \
    jedi \
    bandit \
    yapf \
    rope

sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
       https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
```

#####

##### Inside vim

```
:PlugInstall
:CocInstall coc-git coc-pyright coc-sh coc-json coc-css coc-tsserver coc-eslint coc-prettier coc-snippets coc-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. Link to gacked fonts:

##### Optional stuff

perl very basic lsp server:

```bash
# Install perl module manager
sudo dnf install perl-App-cpanminus

# install language server module
sudo cpanm PLS

```

:Git blame # this will nicely show \
		   # for every line in separate split
           # Useful shortcuts for blame mode:
           # o - jump to patch or blob in horizontal split
           # A, C, D - different display (lenght) modes
           # g? - other keybindings

#other examples:
:Git add .
:Git commit
```

Nice single file diff viewer:

```
:Gdiffsplit
```

```bash
:CocCommand git.<command>

#examples:

:CocCommand git.showCommit
:CocCommand git.showBlameDoc
