## Dialyzer integration

ElixirLS will automatically analyze your project with Dialyzer after each successful build. It maintains a "manifest" file in `.elixir_ls/dialyzer_manifest` that stores the results of the analysis. The initial analysis for a project can take a few minutes, but after that's completed, modules are re-analyzed only if necessary, so subsequent analyses are typically very fast -- often less than a second. It also looks at your modules' abstract code to determine whether they reference any modules that haven't been analyzed and includes them automatically.

You can control which warnings are shown using the `elixirLS.dialyzerWarnOpts` setting in your project or IDE's `settings.json`. To disable it completely, set `elixirLS.dialyzerEnabled` to false.
You can control which warnings are shown using the `elixirLS.dialyzerWarnOpts` setting in your project or IDE's `settings.json`. Find available options in Erlang [docs](http://erlang.org/doc/man/dialyzer.html) at section "Warning options".

To disable Dialyzer completely, set `elixirLS.dialyzerEnabled` to false.

Check usage details in Dialyxir docs on [GitHub](https://github.com/jeremyjh/dialyxir#usage) and [hexdocs](https://hexdocs.pm/dialyxir/readme.html).

ElixirLS's Dialyzer integration uses internal, undocumented Dialyzer APIs, and so it won't be robust against changes to these APIs in future Erlang versions.
