Language	Identifier	Optional alternative identifiers (if any)
C/C++	c-cpp	c or cpp
C#	csharp
Go	go
Java/Kotlin	java-kotlin	java or kotlin
JavaScript/TypeScript	javascript-typescript	javascript or typescript
Python	python
Ruby	ruby
Swift	swift
{% ifversion code-scanning-actions-language %}
{% data variables.product.prodname_actions %} workflows	actions
{% endif %}

Note

If you specify one of the alternative identifiers, this is equivalent to using the standard language identifier. For example, specifying javascript instead of javascript-typescript will not exclude analysis of TypeScript code. You can do this in an advanced setup workflow with the --paths-ignore option.
