Function detect_lang::from_path

pub fn from_path<P: AsRef<Path>>(path: P) -> Option<Language<'static>>

Identifies the language from a path. The casing of the extension does not affect the result.

Note that from_path does not check if the path exists.

Example

assert_eq!(from_path("foo.rs"), Some(Language("Rust", "rust")));
assert_eq!(from_path("foo.md"), Some(Language("Markdown", "markdown")));
assert_eq!(from_path("foo.cpp"), Some(Language("C++", "cpp")));
assert_eq!(from_path("foo.unknown"), None);

// The case is ignored
assert_eq!(from_path("foo.jSoN"), Some(Language("JSON", "json")));
