Here is an example configuration for `languages.toml`

```toml
[[language]]
name = "elixir"
scope = "source.elixir"
injection-regex = "elixir"
file-types = ["ex", "exs"]
roots = ["mix.exs"]
auto-format = false
diagnostic-severity = "Hint"
comment-token = "#"
indent = {tab-width = 2, unit = " "}
language-servers = ["elixir-ls", "credo"]

[language-server.elixir-ls]
command = "elixir-ls"
config = { elixirLS.dialyzerEnabled = true }

[language-server.credo]
command = "/path/to/executable/credo-language-server"
args = ["--stdio=true", "--port=999"]
```

</ul>

## Installation

The preferred way to use credo-language-server is through one of the supported editor extensions.

If you need to install credo-language-server on it's own, you can download the executable hosted by the GitHub release. The executable is an Elixir script that utilizes `Mix.install/2`.

### Note

Credo Language Server creates an `.elixir-tools` hidden directory in your project.

This should be added to your project's `.gitignore`.

## Code Actions

### DisableCheck

Check: all

If there is a check that you'd wish to disable, you can trigger the code action on that line to insert a magic comment to disable that check.

### ModuleDocFalse

Check: `Credo.Check.Readability.ModuleDoc`

Inject a `@moduledoc false` snippet into the module.
