	Lua        Language = "lua"
	Scala      Language = "scala"
	JSON       Language = "json" // Not in AllLanguages(); no LanguageSpec or tree-sitter grammar
)

func AllLanguages

func AllLanguages() []Language

AllLanguages returns all supported languages.

func LanguageForExtension

func LanguageForExtension(ext string) (Language, bool)

LanguageForExtension returns the Language for a file extension.

type LanguageSpec

type LanguageSpec struct {
	Language          Language
	FileExtensions    []string
	FunctionNodeTypes []string
	ClassNodeTypes    []string
