# 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.
More on the "why's" are explained [in my blog post](https://lugh.ch/neovim-lessons-learned.html).

## Installation

1. Install Neovim 0.9.x
1. Install macOS/Windows dependencies documented in `init.lua`
1. Clone this Git repository to
   1. `~/.config/nvim` when on macOS/Linux
   1. `c:\Users\foobar\AppData\Local\nvim` when on Windows

### Finishing touches

- 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`
- Install Mason LSP/linter/formatters in the table down

## Speed

Output from lazy.nvim profiling (`:Lazy profile`) on a MacBook Pro M2 Max,
macOS 14.

### Start and open init.lua

Around 20% of the plugins are lazy-loaded.

```bash
 Startuptime: 81.44ms

Based on the actual CPU time of the Neovim process till UIEnter.
This is more accurate than `nvim --startuptime`.
  LazyStart 11.34ms
  LazyDone  23.66ms (+12.32ms)
  UIEnter   81.44ms (+57.78ms)
```

### Starting with an empty file

Around 65% of the plugins are lazy-loaded.

```bash
Startuptime: 35.89ms

Based on the actual CPU time of the Neovim process till UIEnter.
This is more accurate than `nvim --startuptime`.
  LazyStart 11.55ms
  LazyDone  24.74ms (+13.18ms)
  UIEnter   35.89ms (+11.15ms)
```

## Looks

This is how it looks like:

## Mason essentials

This lists the LSPs/linter/formatters I consider ok for my use cases. Tools may
support many more languages than I document in the "Language" column. The
formatters installed here are used via `conform.nvim`.

| Type      | Language       | Name             | Benefits                   | Issues                    |
| --------- | -------------- | ---------------- | -------------------------- | ------------------------- |
| LSP       | Markdown       | **marksman**     | Autocompletes links        | n/a                       |
| LSP       | Go             | **gopls**        |                            | n/a                       |
| LSP       | Terraform      | **terraform-ls** |                            | n/a                       |
| Linter    | Ansible        | **ansible-lint** |                            | yamllint vs. ansible-lint |
| Linter    | YAML           | **yamllint**     |                            | yamllint vs. ansible-lint |
| Formatter | Markdown, YAML | **prettier**     | Markdown table formatting! | n/a                       |
