Zig Language Server, or `zls`, is a language server for Zig. The Zig wiki states that "The Zig community is decentralized" and "There is no concept of 'official' or 'unofficial'", so instead of calling `zls` unofficial, and I'm going to call it a cool option, one of [many](https://github.com/search?q=zig+language+server).

## Installation

Installing `zls` is pretty simple;

```bash
git clone https://github.com/zigtools/zls
cd zls
zig build
```

### Build Options

| Option | Type | Default Value | What it Does |
| --- | --- | --- | --- |
| `-Ddata_version` | `string` (master or 0.6.0) | 0.6.0 | The data file version. This selects the files in the `src/data` folder that correspond to the Zig version being served.

Then, you can use the `zls` executable in an editor of your choice that has a Zig language server client!

*Note:`zls` itself must be built using the master branch of zig currently due to a bug in `std.json` which was [fixed](https://github.com/ziglang/zig/pull/5167) after 0.6.0 was released.*

### Configuration Options

You can configure zls by providing a zls.json file in the same directory as the executable.  
The following options are currently available.  

| Option | Type | Default value | What it Does |
| --- | --- | --- | --- |
| `enable_snippets` | `bool` | `true` | Enables snippet completion, set to false for compatibility with language clients that do not support snippets (such as ale). |
| `zig_lib_path` | `?[]const u8` | `null` | zig library path, used to analyze std library imports. |
| `warn_style` | `bool` | `false` | Enables warnings for style *guideline* mismatches |

## Usage

`zls` is in its early stages, with a full analysis/completion engine coming soon, but it is still usable. 

### VSCode

Install the `zls-vscode` extension from [here](https://github.com/zigtools/zls-vscode/releases).
