# ALE Supported Languages and Tools

This plugin supports the following languages and tools. All available
tools will be run in combination, so they can be complementary.

<!--
Keep the table rows sorted alphabetically by the language name,
and the tools in the tools column sorted alphabetically by the tool
name. That seems to be the fairest way to arrange this table.

Remember to also update doc/ale.txt, which has a similar list with different
formatting.
