# My Neovim configuration
## Motivation
After doing my first steps with <https://github.com/nvim-lua/kickstart.nvim>,
I decided to roll my own, custom, "lightweight" Neovim configuration in order to
better understand Neovim and its configuration/customization, package managers,
plugins etc. and have "my own" config that only includes things I really need.
## Installation
1. Install Neovim 0.9.x
1. Install OS dependencies documented in `init.lua`
1. Clone this Git repository to `~/.config/nvim`
### Finishing touches
- Install Treesitter comment parser (to highlight `FIXME:/NOTE:/TODO:/XXX:`)
with `:TSInstall comment`
- Create a `$HOME/.ignore` file and add big, useless directories to it, so
Telescope/ripgrep/fd can ignore those. My current list of files/directories is
available in `lua/weeheavy/plugins/telescope-fzf-native.lua`
## Speed
Output from lazy.nvim profiling (`:Lazy`, then `P`):
```bash
Startuptime: 52.04ms
Based on the actual CPU time of the Neovim process till UIEnter.
This is more accurate than `nvim --startuptime`.
LazyStart 10.78ms
LazyDone 48.72ms (+37.94ms)
UIEnter 52.04ms (+3.32ms)
```

## Command cheat sheet
### Vim/Neovim
#### Basics
- `Space` is set as the leader key
#### Plugin things
- `:so` Source file
- `:checkhealth <pluginname>` check for problems of a plugin. Use `:checkhealth`
to check base and all plugins
- `:Lazy` to bring up package manager UI
#### Navigation
##### Code navigation
- `w` move to start of next word (ignores punctuation due to remap)
- `e` move to end of next word (ignores punctuation due to remap)
- `b` move to start of previous word (ignores punctuation due to remap)
##### Code editing
- `leader+i` re-indent whole file
- `i` insert mode at cursor position
- `I` insert mode at the **beginning of the line**
- `a` insert mode **one character after the current** one
- `A` insert mode at the **end of the line**
- `o` insert mode a line **below** the cursor
- `O` insert mode a line **above** the cursor
##### Visual mode
- `v` visual mode at cursor position
- `V` visual mode line mode
- `Ctrl+v` visual block mode
##### Tab navigation
(Don't use tabs by default, but use buffers instead).
- `Ctrl+t` to open a file in e.g. a Telescope finder in a new tab
- `gt` or `gT` to switch between open tabs
##### Window navigation
- `Ctrl+wq` close window
- `Ctrl+ws` split window horizontally
- `Ctrl+wv` split window vertically
- `Ctrl+<h/j/k/l>` switch between split windows
##### Buffer navigation
- `Space+Space` shows open buffers (via `Telescope buffers`)
### Telescope
#### Navigation in live_grep, find_files, git_status and file_browser
- `↓` or `Ctrl+n` scroll down (**n**ext) file list
- `↑` or `Ctrl+p` scroll up (**p**revious) file list
- `Ctrl+d` scroll **d**own in preview
- `Ctrl+u` scroll **u**p in preview
- `Ctrl+/` help
### Treesitter
- `:TSUpdate` update all parsers
- `:TSModuleInfo` show installed parsers
## Open issues/TODOs
- Hinting for trailing spaces (EOL) and blank space on line
- LSP setup/config (mason?), consume <https://blog.pabuisson.com/2022/08/neovim-modern-features-treesitter-and-lsp/>
- ollama integration <https://github.com/nomnivore/ollama.nvim>
- Solution to run file_browser when doing a vertical/horizontal split?
