Language server for systemd unit files. Result of an exercise to learn the language server protocol.

## Supported Features

### `textDocument/completion`

Completion for

- unit file directives
- unit file sections

### `textDocument/hover`

Documentation for directives supplied on hovering.

![](https://raw.githubusercontent.com/psacawa/systemd-language-server/master/assets/hover.gif)

For markup in hover windows (i.e. the fancy highlighting), `pandoc` must be found in `$PATH`. Otherwise, there will be fallback to plain text.

## Installation

```
pip install systemd-language-server
```

```json
...

  "command": "systemd-language-server",
  "filetypes": ["systemd"]
}
...
```

### nvim-lspconfig

```lua
local lspconfig = require 'lspconfig'
local configs = require 'lspconfig.configs'

if not configs.systemd_ls then
  configs.systemd_ls = {
    default_config = {
      cmd = { 'systemd-language-server' },
      filetypes = { 'systemd' },
      root_dir = function() return nil end,
