Documentation: Add nvim-lspconfig support to Neovim config guide
`nvim-lspconfig` has become more popular recently and is from the Neovim organization directly. Headers have also been shifted to match other documentation files.

# NVim Project Configuration
|
||||
# Neovim Project Configuration
|
||||
|
||||
NVim can be configured to use the [COC-clangd](https://github.com/clangd/coc-clangd)
|
||||
There are two documented ways to support clangd in Neovim for the Ladybird
|
||||
project:
|
||||
|
||||
1. With [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) (assumes existing setup)
|
||||
2. With [coc.nvim](https://github.com/neoclide/coc.nvim) (from scratch, potentially out of date)
|
||||
|
||||
For both setups, make sure you ran `./Meta/ladybird.sh run ladybird` at least
|
||||
once. Additionally, clangd should be configured with the following (in the
|
||||
`.clangd` file at the root of the project):
|
||||
|
||||
```yaml
|
||||
CompileFlags:
|
||||
CompilationDatabase: Build/ladybird
|
||||
|
||||
Diagnostics:
|
||||
UnusedIncludes: None
|
||||
MissingIncludes: None
|
||||
```
|
||||
|
||||
## With nvim-lspconfig
|
||||
|
||||
> Note: This guide assumes Lua is being used, but can easily be adapted to
|
||||
> VimScript.
|
||||
|
||||
If you have an [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig), setup
|
||||
already, registering clangd is similar to other LSPs:
|
||||
```lua
|
||||
require('lspconfig').clangd.setup {
|
||||
-- If you have an on_attach function, this is where you'd put it. If not,
|
||||
-- you can delete this line.
|
||||
-- on_attach = ...,
|
||||
|
||||
-- This is where you'd put capabilities (i.e. if you're useing nvim-cmp)
|
||||
-- capabilities = ...,
|
||||
|
||||
-- If you have another clangd installation, put it here. Note that we use
|
||||
-- clangd version 18 for the Ladybird project.
|
||||
-- cmd = { '/path/to/clangd' },
|
||||
}
|
||||
```
|
||||
|
||||
A base `setup` call should be enough to register the LSP, but if false-negative
|
||||
LSP errors occur upon opening Neovim, make sure your clangd installation is at
|
||||
least version 18.
|
||||
|
||||
## With coc.nvim
|
||||
|
||||
> Note: This guide assumes VimScript is being used, but can easily be adapted to
|
||||
> Lua. It also starts from scratch.
|
||||
|
||||
Neovim can be configured to use the [coc-clangd](https://github.com/clangd/coc-clangd)
|
||||
plugin to provide code-completion as well as inline
|
||||
[git blame](https://github.com/f-person/git-blame.nvim) using [vim-plug](https://github.com/junegunn/vim-plug).
|
||||
Formatting can also be configured with [formatter.nvim](https://github.com/mhartington/formatter.nvim).
|
||||
|
||||
Make sure you ran `Meta/ladybird.sh run ladybird` at least once already.
