## README

# lsp_extensions.nvim

Repo to hold a bunch of info & extension callbacks for built-in LSP. Use at your own risk :wink:

## Install

Requires Built-in LSP, [Neovim Nightly](https://github.com/neovim/neovim/releases/tag/nightly), [nvim-lsp](https://github.com/neovim/nvim-lsp)

```vimscript
" LSP Extensions
Plug 'nvim-lua/lsp_extensions.nvim'
```

### Available Features

#### Rust
- [Inlay Hints](#inlay-hints-rust-analyzer)

#### Dart

- [Outline](#outline-dartls)

#### Diagnostics

## Inlay Hints (rust-analyzer)

![Customized](https://i.imgur.com/FRRas1c.png)

Inlay hints for the whole file:

```vimscript
nnoremap <Leader>T :lua require'lsp_extensions'.inlay_hints()
```

Only current line:

```vimscript
nnoremap <Leader>t :lua require'lsp_extensions'.inlay_hints{ only_current_line = true }
```

Run on showing file or new file in buffer:

```vimscript
autocmd BufEnter,BufWinEnter,TabEnter *.rs :lua require'lsp_extensions'.inlay_hints{}
```

On cursor hover, get hints for current line:

```vimscript
autocmd CursorHold,CursorHoldI *.rs :lua require'lsp_extensions'.inlay_hints{ only_current_line = true }
```

By default only ChainingHint is enabled. This is due to Neovim not able to add virtual text injected into a line. To enable all hints: 
**Note:** Hints will overwrite if other hints using this. Only the last hint will be shown. 

```vimscript
:lua require('lsp_extensions').inlay_hints{ enabled = {"TypeHint", "ChainingHint", "ParameterHint"} }
```

Available Options (Showing defaults):

```lua
require'lsp_extensions'.inlay_hints{
	highlight = "Comment",
	prefix = " > ",
	aligned = false,
	only_current_line = false,
	enabled = { "ChainingHint" }
}
```

```vimscript
autocmd InsertLeave,BufEnter,BufWinEnter,TabEnter,BufWritePost *.rs :lua require'lsp_extensions'.inlay_hints{ prefix = ' » ', highlight = "NonText", enabled = {"ChainingHint"} }
```

## Workspace Diagnostics

To enable workspace diagnostics, you'll want do something like this:

```lua
-- use the same configuration you would use for `vim.lsp.diagnostic.on_publish_diagnostics`.
vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(
  require('lsp_extensions.workspace.diagnostic').handler, {
    signs = {
      severity_limit = "Error",
    }
  }
)
```

To use workspace diagnostics, you can do some of the following:

```lua
-- Get the counts from your curreent workspace:
local ws_errors = require('lsp_extensions.workspace.diagnostic').get_count(0, 'Error')
local ws_hints = require('lsp_extensions.workspace.diagnostic').get_count(0, 'Hint')

-- Set the qflist for the current workspace
--  For more information, see `:help vim.lsp.diagnostic.set_loc_list()`, since this has some of the same configuration.
require('lsp_extensions.workspace.diagnostic').set_qf_list()
```
