README
# Expert
Expert is the official language server implementation for the Elixir programming language.
## Installation
You can download Expert from the [releases page](https://github.com/elixir-lang/expert/releases) for your
operating system and architecture. Put the executable somewhere on your `$PATH`, like `~/.local/bin/expert`
For editor specific installation instructions, please refer to the [Installation Instructions](pages/installation.md)
### Nightly Builds
If you want to try out the latest features, you can download a nightly build.
Using the GH CLI, you can run the following command to download the latest nightly build:
```shell
gh release download nightly --pattern 'expert_linux_amd64' --repo elixir-lang/expert
```
Then point your editor to the downloaded binary.
### Building from source
Expert can be built in two ways: building a regular release for your own system(a "plain" release), or building
a "burrito" release that works on multiple systems.
To build Expert for your system, run the following command:
```sh
just release
```
You can then point your editor to the `start_expert` executable in the generated release.
You can also run `start_expert --help` to see available options.
> [!IMPORTANT]
>
> If your editor doesn't do it automatically, make sure to pass the `--stdio` flag to Expert.
To build Expert using burrito, you need Zig `0.15.2` installed on your system.
Later versions will not work.
Then you can run the following command:
```sh
just burrito-local
```
This will build the Expert binary and place it in the `apps/expert/burrito_out` directory. You can then point your
editor to this binary.
You can find more information in the [Installation Instructions](pages/installation.md).
