Mix tasks to simplify use of Dialyzer in Elixir projects. Elixir 1.6 is required, to support the new pretty printing feature. If your project is not yet on 1.6, continue to specify 0.5 in your mix deps. Warning messages have been greatly improved, but are filtered through the legacy formatter to support your existing ignore files. You can optionally use the new Elixir term format for ignore files. You may want to use the --format short argument in your CI pipelines. There are several formats, also there is a new explain feature - for details see CLI options. If you are planning to use Dialyzer with an application built with the Phoenix Framework, check out the Quickstart wiki. Use dialyxir from the directory of the mix project you want to analyze; a PLT file will be created or updated if required and the project will be automatically compiled.
Features
- Dialyzer is a static analysis tool for Erlang and other languages that compile to BEAM bytecode for the Erlang VM
- It can analyze the BEAM files and provide warnings about problems in your code including type mismatches
- The analysis can be improved by inclusion of type hints (called specs)
- OTP application dependencies are (transitively) added to your PLT by default
- Explanations are available for classes of warnings
- Dialyzer supports a number of warning flags used to enable or disable certain kinds of analysis features
